According to Article 65(4) of the Constitution, the maximum term of any given Parliament is five years from the date of its first sitting following a general election, after which it is dissolved by operation of law. However, the prime minister may advise the President to dissolve Parliament at any time during the five-year period. A general election must be held within three months after every dissolution of Parliament. Elections are conducted by the Elections Department (ELD), which is under the Prime Minister's Office.

There are 93 elected seats in Parliament organised into 14 Single Member Constituencies (SMCs) and 17 Group Representation Constituencies (GRCs). Each SMC returns one Member of Parliament using the first past the post (FPTP) voting system, while each GRC returns four or five MPs through the party block voting electoral system, where at least one of whom must be from the Malay, Indian or other minority communities. A group of candidates wishing to stand for election in a GRC must all be members of the same political party, or a group of independent candidates, resulting in a situation where the victorious party obtains 100% of the seats in a given GRC. The voting age in Singapore is 21 years, with eligibility to voters who were born before 1 March 1999.

On 23 June 2020 at 16:00 Prime Minister Lee Hsien Loong announced during a live televised announcement that President Halimah Yacob had dissolved the 13th Parliament of Singapore on the same day and had issued a writ of election with nominations to be held a week later on 30 June 2020.

The returning officer was Tan Meng Dui, a former deputy secretary at the Ministry of National Development and CEO of the National Environment Agency. This is his first election as Returning Officer, taking over from Ng Wai Choong who had served in this role in the previous general election.

The governing People's Action Party has been in power since 1959 and is currently led by the prime minister, Lee Hsien Loong. The leading opposition party is the Workers' Party led by Pritam Singh, with six elected seats and three NCMP seats before the election. A total of ten opposition parties challenged the ruling party in this election.

The Elections Department introduced several new features for this election to help ease the election process for voters, candidates and election volunteers. Registration of voters on polling day will be done electronically and election officials need not manually strike out a voter's particulars from a hardcopy register of electors. Voters will be able to mark their candidate(s) choices more clearly using self-inking pens and enjoy shorter queuing time with the introduction of the e-registration system. Candidates are able to fill in most of the necessary documents online while election volunteers are able to count the number of votes within a shorter duration with the help of counting machines, enabling election results to be released at least 50 minutes earlier. In addition, there will be more polling stations, reducing the average number of voters per polling station from 3,000 to about 2,400. Senior citizens above the age of 65 will be given priority to vote between 8 am and 12 pm on Polling Day.

Election recount can occur if the margin of results for a constituency are within a 2% range (or scores between 49% and 51%). Unlike the previous elections, the recount is now triggered automatically rather than being called out manually from the candidates or counting agents, which was previously seen in 1991 (Nee Soon Central SMC), 2011 (both Presidential and Potong Pasir SMC) and 2015 (Aljunied GRC); additionally, a standby counting machine would be used for recount instead of being manually counted. Similar to past elections, overseas votes is disregarded during a recount of votes as it does not cause any impact from the eventual results, unless if the total overseas electorate is greater than the difference of votes.

On 27 January 2016, an amendment to the Constitution was passed, increasing the minimum number of opposition Members of Parliament by three to 12 members. This is the first increase for the number of opposition MPs allocated since the 2011 Singaporean general election, when it was increased from three members to nine. As in the case for previous elections, NCMP seats are offered to the best-performing non-elected opposition candidates, with the number determined by the total number of opposition candidates elected; if there are at least 12 opposition candidates elected, then NCMP seats will not be offered, as previously seen in the 1991 election. The names of the eligible candidates are announced a few days after the polling day. Candidates may decline the post if offered, as was seen previously in the 1984 and 2015 elections.

The Electoral Boundaries Review Committee is made up of senior civil servants and charged with adjusting the boundaries of electoral divisions prior to an election. The government officially claims this as necessary to ensure minority participation in Parliament amidst demographic changes while ensuring an equitable number of voters represented per MP, though critics have raised allegations of gerrymandering to disadvantage the opposition. As of 2015, there were 16 GRCs and 13 SMCs. Prime Minister Lee convened the committee on 1 August 2019 with instructions to reduce the size of GRCs and increase the number of SMCs. The exact date of formation was revealed only when Pritam Singh asked Trade and Industry Minister Chan Chun Sing in a written reply in Parliament.

The Committee released its report on 13 March 2020 with the formation of 17 GRCs and 14 SMCs. For the first time since 1991, six-member GRCs were eliminated and reduced to five. A new Sengkang GRC was formed from portions of the former Punggol East and Sengkang West SMCs and the boundaries of Tampines GRC were altered for the first time since 2001, due to the increase in population in the northeastern area of Singapore. Four new SMCs were also carved out (Kebun Baru, Yio Chu Kang, Marymount and Punggol West), three former SMCs were absorbed into neighbouring GRCs (Fengshan, Punggol East and Sengkang West), while two SMCs (Hong Kah North and Potong Pasir) had their boundaries modified. The remaining SMCs and four GRCs (Aljunied, Holland–Bukit Timah, Jurong and Tanjong Pagar) were left untouched, though the Workers' Party raised questions on the abolition of SMCs that it had previously contested and lost by a narrow margin. The changes saw about 13% of voters being allocated to a new constituency and increased the number of seats from 89 to 93.

The changes made in the electoral divisions are as follows:

During a Straits Times forum on 11 March, Deputy Prime Minister Heng Swee Keat said that the timing of the elections could be affected in view of the worsening pandemic. On 25 March, Senior Minister Teo Chee Hean told Parliament that he believed it would be unconstitutional for the President to form a caretaker government unless a state of emergency had been recommended by the Cabinet to the President.

On 28 March, Tan Cheng Bock responded to Teo's comments by saying that the unconstitutional nature of a caretaker government as a result of a postponing a general election would be far more preferred than having a health emergency by exposing millions of Singaporeans to potential COVID-19 infection.

On 7 April, Minister for Trade and Industry Chan Chun Sing introduced the Parliamentary Elections (COVID-19 Special Arrangements) Bill to Parliament which would allow voters under Stay-Home Notices or Quarantine Orders related to COVID-19 to vote outside of their normal electoral divisions in the upcoming General Election. The Bill was passed by Parliament on 4 May and assented to by the President on 15 May. The Parliamentary Elections (COVID-19 Special Arrangements) Act 2020 came into operation on 26 May.

On 1 July, the Parliamentary Elections (COVID-19 Special Arrangements) Regulations 2020 was made to provide for mobile polling teams at special polling stations and to allow voters who have fever or on COVID-19 stay orders to vote from 7 pm to 8 pm on polling day.

On 18 June, the ELD introduced temporary measures to reduce the risk of transmission of COVID-19, such as no rallies and TV screenings pertaining to the election are to be held, instead replacing with e-rallies and a new "Constituency Political Broadcast", and nomination centres will no longer admit members of the public or supporters during nomination day. Walkabouts and campaigning vehicles are still allowed, though safe distancing and minimal physical contact still applies, and candidates are also not allowed to make speeches or physical rallies, including during the campaigning from campaigning vehicles, meaning that there will be no parades held by the candidates after the election, though it can still broadcast any pre-recorded messages.

Voters were given a recommended two-hour time slot to cast their vote on Polling Day (from 8 am to 8 pm) on their ballot card as a measure to counter long queues during polling. Measures for safe distancing still apply on polling day. Voters with fever or respiratory symptoms would be denied entry from the polling stations, except during the last hour (7 pm to 8 pm). Voters who are unable to vote because of medical issues, or because they are overseas, will be delisted from the registrar of voters due to mandatory voting, but will not need to pay the $50 fee for reinstating their names. Voters had to use hand sanitizer before voting, and were initially required to wear disposible gloves, but this was later changed due to the requirement causing long queues. Elderly voters above the age of 65 were given a special time slot in the morning. The restrictions caused long queues at polling stations.

For overseas voting (which was held in ten cities, Dubai, London, Tokyo, Beijing, Washington, D.C., Hong Kong, Shanghai, San Francisco, New York City and Canberra), voting was subject to the approval of the authorities in the affected countries, while ELD announced that they would release the arrangements for returning Singaporeans who are issued a mandatory 14-day stay home notice to vote in hotels and reducing the risk of infecting others. These arrangements were later officially announced on 1 July, when the Singapore government announced that special polling stations will be set up in Marina Bay Sands and JW Marriott Hotel Singapore South Beach to accommodate voters serving their stay-home notices in the two hotels.

350 voters who are quarantined at the time did not vote as they are not allowed to leave their place where they were currently isolated to cast their vote.

The polls were slated to close at 8 pm; however, in an unprecedented move in Singapore electoral history, the Elections Department extended the voting hours till 10 pm, just within two hours before its initial closing time. According to the Elections Department, there were long queues at some polling stations, and the extension was to "allow enough time for all voters to cast their votes". This drew criticism from several opposition parties for compromising the integrity of the election, as some were unable to field a polling agent to supervise the sealing of ballot boxes. The Elections Department replied that polling and counting procedures will continue as normal.

On 13 March 2016, the PAP MP for Bukit Batok SMC David Ong resigned over personal indiscretions with a party grassroots activist. In the subsequent Bukit Batok by-election, the PAP candidate and former Aljunied GRC candidate Murali Pillai defeated the opposition SDP candidate Chee Soon Juan to reclaim the seat for the PAP.

In the lead up to the 2017 Singapore presidential election, Speaker of Parliament and MP for Marsiling–Yew Tee GRC Halimah Yacob resigned from the party on 7 August 2017 to fulfil regulations which prohibit the President of Singapore from any party affiliations. As she had vacated her seat in Parliament, there were calls for a by-election, though the Court of Appeal eventually ruled that there was "no duty to call a by-election when a single vacancy arises in a GRC".

On 23 November 2018, Heng Swee Keat and Chan Chun Sing were respectively elected as the party's first and second assistant secretary-general to the PAP's 35th Central Executive Committee (CEC). The two assistant posts were seen as an indicator of Lee Hsien Loong's successor, given that the upcoming election is likely to be Lee's last. Following the announcement of Heng Swee Keat's appointment as the sole deputy prime minister on 1 May 2019, succeeding Teo Chee Hean and Tharman Shanmugaratnam, former MP Inderjit Singh said that the PAP intends to showcase Heng's imminent ascent to the top post and dispel rumours of any surprises in the leadership succession.

On 3 November 2017, then-secretary-general and Aljunied GRC incumbent MP Low Thia Khiang announced during a speech on the party's 60th anniversary that he would not contest the next party elections. During the party's 2016 CEC election, Chen Show Mao had mounted a surprise challenge for the leadership post but lost the election to Low in a 41–65 vote. In the leadership election on 8 April 2018, Pritam Singh was elected unopposed as successor to Low as the party's new secretary-general.

Observers say that the lack of a contest was a good sign of internal unity, and that the party is keen to demonstrate its multiracial credentials now that it has a non-Chinese secretary-general, for the first time since 2001 with J. B. Jeyaretnam.

On 30 April 2020, Low was hospitalised due to a head injury, and was discharged on 21 May. On 25 June, while Low was on rehabilitation, the party announced he (and along with Chen and Png Eng Huat) will not seek election for the first time in his 32-year career, though he has not ruled out his retirement from politics; in his interview, he cited his satisfaction on his leadership, saying that 'I felt my work was done'.

• 2011 presidential election candidate and former Ayer Rajah SMC MP Tan Cheng Bock returned to politics under the Progress Singapore Party that he founded together with several previously contested candidates on 18 January 2019. The PSP was registered by the Registrar of Societies on 28 March 2019. The PSP announced on 26 June 2020 its line-up of candidates for the nine constituencies it will be contesting, with party chief Tan Cheng Bock leading a team in West Coast GRC, a ward that has his former constituency of Ayer Rajah.
• Former leader of the National Solidarity Party, Lim Tean founded Peoples Voice which was registered by the Registrar of Societies on 31 October 2018.
• On 29 May 2020, Ravi Philemon and Michelle Lee jad submitted an application to register a new political party, Red Dot United (RDU), with the Registrar of Societies. Prior to the foundation, they were former members from the Progress Singapore Party. The party was registered on 15 June 2020.

• Singapore Democratic Party began campaigning on 23 February 2019, and announced a few key campaign agendas over March and May that year. Ahead of the election, the party recruited ex-DPP leader Benjamin Pwee.
• On 16 October 2019, the Singapore People's Party saw its first major leadership change since its formation with opposition veteran Chiam See Tong stepping down as secretary-general of the SPP after holding the post for 23 years since December 1996, with former Non-constituency Member of Parliament Steve Chia succeeding Chiam on 5 November 2019.
• On 3 January 2020, four political parties (Singaporeans First, People's Power Party, Reform Party and Democratic Progressive Party) formally agreed to contest in the election as an alliance. Three months later, on 1 April, the four parties decided to join the Singapore Democratic Alliance instead; however, the SDA has since placed their membership applications on hold, though it seeks to maintain an informal alliance. On 25 June, Singaporeans First's chief Tan Jee Say announced the party's dissolution. On 27 June, the Democratic Progressive Party announced its withdrawal from contesting the election.

Polls closed at 10 pm and vote counting began soon after. The results were announced by the returning officer Tan Meng Dui, who is also CEO of the National Environment Agency.

Similar to the 2015 Singaporean general election and 2016 by-election, sample counts were released by the Elections Department prior to the announcement of the actual results to prevent any unnecessary speculation or reliance on unofficial sources of information while counting was still under way.

The first results were announced at 1:22 am for Bukit Panjang SMC where the PAP's Liang Eng Hwa was elected with 53.74% of the vote. The last results came at 3:44 am, when Aljunied GRC and Nee Soon GRC were announced to have been retained by WP leader Pritam Singh and the PAP with 59.93% and 61.90% respectively.

PAP's vote share island-wide was reduced to 61.24%, down from 69.86% in the last election in 2015 and its lowest share since the 2011 elections. In addition to retaining the six seats it held in the last election, the WP also went on to win the new Sengkang GRC, making it the second GRC to be won by an opposition party and the first time in history a new constituency was captured by an opposition party on its first attempt, creating the largest representation for any single opposition party in Parliament since independence, with 10 MPs. WP's victory in Sengkang also lead to the defeat of cabinet minister Ng Chee Meng, who became the third cabinet minister to lose re-election since independence, after Lim Hwee Hua and George Yeo lost in Aljunied in 2011. The WP also broke the record for overall contested vote share for any opposition party with 50.49% of the votes, surpassing the previous record of 48.55% held by the Singapore Democratic Party in 1991. Six candidates, one from a SMC and five from a GRC, each lost their $13,500 deposit in the election, the biggest number of candidates to do so since the 1980 election. Furthermore, out of 40 female candidates, 28 women (including four opposition members) were elected as MPs, setting a record for the most ever female MPs in parliament, at 29% of the chamber, including its first female minority opposition and youngest MP-elect at 26 years of age, Raeesah Khan.

In western Singapore, the PSP and SDP made massive inroads, reducing landslide PAP vote margins with huge swings against the PAP, converting them into marginal seats, most notably Bukit Batok (54.80%), Bukit Panjang (53.74%) and West Coast (51.69%). The latter also saw a swing of 26.88% against the PAP, the largest in any constituency in this election, which helped the PSP win two non-constituency seats even as the PAP retained the constituency. They were taken up by Hazel Poa and Leong Mun Wai for achieving the best-performing non-elected result of any opposition slate, which was confirmed on 14 July. For the second consecutive election, the PAP safe seat of Jurong GRC saw the best result of the PAP, or any party, in any constituency in the election, with 74.62% of the vote.

Excluding the overseas electorate, voter turnout was 95.54%, or 2,535,565 voters, the highest turnout rate of any election (including both general and presidential elections) since the 1997 general election, when 95.91% voted. 1.81% of votes cast were invalid votes, the lowest rate in a general election in independent Singapore, and the lowest rate since the 1963 election when 0.99% were invalid (when Singapore was still a state in Malaysia).

In a press conference held in the early hours of 11 July following the results, Prime Minister Lee described PAP's 61.24% of the popular vote as "respectable" and reflected "broad-based support for the PAP" but "was not as strong a mandate as [he] had hoped for". He pledged to use the "clear mandate" responsibly to take Singapore "safely through the (COVID-19) crisis and beyond". Lee also acknowledged that there was a "clear desire" for alternative voices in parliament especially from young and first time voters and called the loss of three incumbent office holders in Sengkang as a "major loss" to his team. In an unprecedented move, Lee announced that Workers' Party leader Pritam Singh would be designated as the official Leader of the Opposition and "will be provided with appropriate staff support and resources" to perform his role. Lee added that 24 newly elected first-time PAP MPs will "reinforce the renewal process" of the party. Lee added that he was "determined" to hand over to a new team of leaders in good working order after the COVID-19 crisis is overcome. Finally, PM Lee also suggested that disruption caused by the circuit breaker and the safe distancing restrictions just before the election which led to loss of income and jobs was reflected in the results.

PM Lee added that a thorough review into the conduct of the election would take place, acknowledging that the arrangements "could have been done better" following the reports of long queues at polling stations caused by additional arrangements for COVID-19.

Speaking later in the day while thanking voters with his successful GRC team in Nee Soon GRC, Law and Home Affairs Minister K. Shanmugam said "a lot of soul searching and reflection" would be required to understand the message sent by the voters in the swing against PAP. When asked on his view of the PAP statement which questioned Sengkang GRC WP candidate Raeesah Khan of whether she was "worthy of consideration as an MP" which was said to have backfired and resulted in a WP victory, Shanmugam suggested that the older generation of Singaporeans takes a different approach with the younger generation of how race and religion is discussed in Singapore. Shanmugam added there "needs to be a way in which the viewpoints of younger Singaporeans" are addressed. In a radio interview with Money FM 89.3 on 28 July, he mentioned that the results reflected the strain in the economy amid COVID-19, and adding that he was keenly aware of the voters' desire, especially younger ones, for diversity of representation in Parliament, with a difference between perception and reality.

Former prime minister Goh Chok Tong called PAP's victory a "clear mandate" and called PM Lee's move to designate Pritam Singh as official leader of the opposition a "very significant move". He added opposition MPs and NCMPs will now have to "go beyond merely serving as a check-and-balance" and "put forward their alternative policies and solutions" to Singaporeans.

On 17 July, Lawrence Wong mentioned on a separate virtual conference for the multi-task force relating to the social distancing in Hougang Avenue 5 after the polling hours ended that featured a large group of WP supporters making close contacts despite wearing masks and safe distancing, which produced a safe-distancing risks by individuals. Wong told that Singaporeans should not be complacent and added a warning that "anyone decides to abandon caution, thinks that, 'It's okay'" could "put the whole country at risk". Despite the warning, however, there was no change in the enforcement and Wong believed that polling was conducted in open spaces and there was no close contact in terms of touching and talking, and had arranged voters different safety protocols while they cast their votes.

On 19 July, Senior Minister and Co-ordinating Minister for Social Policies Tharman Shanmugaratnam mentioned that the politics had been changed permanently after the election, one with a solid mandate and one for a changing electorate, adding a fact on the results that "were also good for opposition politics", especially the performance for the WP and "reflected a discerning public and a political culture that bodes well for Singapore." Tharman aimed to achieve the balance and having a "vigorous and informed" debate between PAP and the oppositions in the upcoming government to improve efficiency and democracy.

Workers' Party leader Pritam Singh said he was "grateful" and "humbled" at the support WP received, adding that he was "not feeling euphoric at all" and acknowledged "a lot of work to do". He reminded the successful candidates to keep their feet "firmly grounded" after the WP secured a second GRC in Sengkang and held onto Aljunied and Hougang with increased margins. In a Facebook post, he wrote that he looked forward to doing his best serving as leader of the opposition.

Progress Singapore Party leader Tan Cheng Bock said he was proud that his party achieved an average vote share of 40.85% in the seats it contested on their maiden election despite being founded a year prior. He called it "the beginning of a new chapter for PSP", and believes the "movement" that he created will grow. He added that the party executive committee will discuss sending two candidates from West Coast GRC to serve the NCMP role in Parliament.

Singapore Democratic Party leader Chee Soon Juan said the SDP ran a "very good campaign" focused on policies and issues but "came up short" on winning. He thanked voters and said the SDP "will continue to press on". SDP chairman Paul Tambyah added they could "hold (their) heads high for a strong campaign under the circumstances" and "will do better the next time". Tambyah accused the PAP government of "recklessness and opportunism" for holding the election during a pandemic, and also called the long queues of voters due to the requirement to wear gloves when casting ballots and lack of personal protective equipment for polling agents when voters on stay home orders came to vote as a "fiasco".

Under the current constitution, opposition will be guaranteed 12 parliamentary seats which may consist of elected members of parliament (MP) from the opposition team and unsuccessful candidates in this election from the best-performing losing opposition party or parties. The number of NCMPs offered will be 12 less the number of elected MPs; there are 10 opposition-elects and thus two NCMPs will be offered after the election. Additional rules also states there could be up to two NCMPs from the best performing GRC and one from the best performing SMC.

Since the Progress Singapore Party (PSP) team led by Tan Cheng Bock contesting in the West Coast GRC were the best-performing losing opposition team by garnering 48.31% of valid votes, both NCMPs seats were offered to PSP. On 14 July, PSP announced that Hazel Poa and Leong Mun Wai will take up the two NCMP positions, making them the third and fourth NCMPs that were not from WP, and a parliament with three parties representing since the 12th Parliament; it also marked the first election since 2001 the NCMPs are not awarded to WP. Leong and Poa's election as NCMPs were finalised by the Returning Officer Tan on 16 July.

On 14 July, Koh Siong Ling, the head of the Election Department, issued an apology to the public and senior voters, while conducting a review on what went wrong during the election, such as long queues during voting in the early morning hours (a timing block reserved for senior voters) unlike previous elections, and the queues which was likely caused by an unnecessary, additional step on equipping disposable gloves, as voters had sanitised their hands a few times prior. ELD also acknowledged the procedures needed to ensure safety of the voters while revealed that they have removed a mandatory step on wearing gloves in the midst of election and there were difficulties experienced by voters on its station layout, though revealed that the queues were mostly improved by 2 pm and the extension of polling hours, despite adopting safe distancing practices. ELD also reviewed that 13 voters who were still serving the Stay-Home Notice did not vote that day due to the duration.

On 15 July, ELD revealed that a technical glitch had occurred in one of the voting centers for Holland-Bukit Timah GRC. A voter had reported being unable to vote due to the system stating that she had already cast her vote prior. The case was escalated to the assistant returning officer and the police. Investigations revealed human error had resulted in the e-registration system being inadvertently logged out which prevented the registration of her NRIC into the system. ELD subsequently apologised to the voter over the mishap and allowed her to restore her name while exempting the $50 payment fee.

At about 11:40 pm on 15 July, Elections Department published a report for overseas votes. The turnout was 4,794, or 72.97% out of the 6,570 voters in total, bringing the overall turnout to 2,540,359 and its percentage to 95.81%. Excluding the 50 spoilt/invalid votes, only 2,710 voters had voted in favour for PAP but percentages for the majority of the constituencies were in favour towards the opposition except for six (Hong Kah North SMC, Pasir Ris-Punggol GRC, Pioneer SMC, Potong Pasir SMC, Punggol West SMC and Sengkang GRC). While the percentages for the 10 constituencies (Ang Mo Kio GRC, Bukit Batok SMC, Chua Chu Kang GRC, Holland-Bukit Timah GRC, Marsiling-Yew Tee GRC, Marymount SMC, Nee Soon GRC, Sembawang GRC, Tampines GRC and Yuhua SMC) were not affected, the PAP's vote share fell to 61.23%. The vote counting was held inside the Elections Department Training Centre at Victoria Street under the witness of most Workers' Party candidates.

The new cabinet was announced on a live televised announcement held in The Istana by Prime Minister Lee on Saturday, 25 July at 2:30 pm on his Facebook page as well as CNA, CNA938 and YouTube. While most ministry portfolios from the last Parliament were unchanged, Deputy Prime Minister Heng Swee Keat was also conferred a brand new portfolio for Co-ordinating Minister for Economic Policies. Ong Ye Kung became the Transport Minister, Lawrence Wong became the Education Minister, Desmond Lee became the National Development Minister and is also given an additional new portfolio for Minister-in-charge of Social Service Integration; Masagos Zulkifli was appointed as a Social and Family Development Minister and a second minister for Health while relinquishing his Environment Ministry portfolio to Grace Fu (portfolio renaming to Ministry of Sustainability and the Environment); Indranee Rajah was given National Development portfolio while relinquishing Education and retained both her Prime Minister's Office and Finance portfolios. Lee mentioned that not changing most existing portfolios was to promote continuity and urging a need for experienced ministers to provide steady hands and mentoring the younger ministers, especially during the ongoing COVID-19 crisis.

Eight existing MPs were also promoted, among which Senior Ministers of State Edwin Tong and Maliki Osman were promoted to Cabinet ministers as Minister for Culture, Community and Youth and Second Minister for Law, and Minister in the Prime Minister's Office and Second Minister for Education and Foreign Affairs, respectively; Backbencher Rahayu Mahzam was promoted to Parliamentary Secretary in the Ministry of Health with effect on 1 September; Minister of State for Manpower Zaqy Mohamad promoting to a Senior Minister of State and also given the Defence portfolio; senior Parliamentary Secretaries Low Yen Ling, Faishal Ibrahim and Sun Xueling as Ministers of State while given new portfolios (Low as Culture, Community and Youth and Trade and Industry, Faishal as Home Affairs and National Development, and Sun as Education and Social and Family Development); and Alex Yam as the new mayor for North West Community Development Council replacing Teo Ho Pin.

While not announced live, other portfolios were changed for five existing Senior Ministers of State, among which Amy Khor relinquished her Health portfolio for Transport while retaining Sustainability and Environment, Sim Ann relinquished Culture, Community and Youth portfolio for National Development while retaining Communications and Information, Chee Hong Tat relinquishing both portfolios for Education and Trade and Industry for Foreign Affairs and Transport, Janil Puthucheary relinquishing Transport portfolio for Health while retaining Communications & Information, and Koh Poh Koon relinquishing Trade and Industry portfolio for Health. Additionally, Tan Wu Meng have relinquished his Senior Parliamentary Secretary portfolios (Foreign Affairs and Trade and Industry) and returned to a backbencher, while Baey Yam Keng relinquished his Culture, Community and Youth portfolio but retained his Transport ministry. The Co-ordinating Minister for Infrastructure did not announce its successor and thus became vacant.

Seven fresh MPs were promoted in the office, among which Tan See Leng become the third MP (after Heng and Richard Hu) to be directly promoted to a Cabinet Minister, taking on the portfolios for the Prime Minister's Office and Second Minister for Manpower and Trade and Industry; four were given Minister of State portfolios, namely Gan Siow Huang (Education and Manpower), Alvin Tan (Culture, Community and Youth and Trade and Industry), Desmond Tan (Home Affairs and Sustainability and Environment) and Tan Kiat How (Prime Minister's Office and National Development); Eric Chua promoting as a Parliamentary Secretary in the Ministry of Culture, Community and Youth and Social and Family Development with effect on 1 September; and Mohd Fahmi Aliman as the new mayor for South East Community Development Council replacing Maliki.

A total of 37 MPs out of 93 were office holders, the same number that comprises the previous cabinet; they were inaugurated two days later on 27 July at separate venues in Parliament House and in The Istana due to safe distancing, a first in Singapore's history the inauguration were held at multiple venues. Finally, Prime Minister Lee announced that the annual National Day Rally will be cancelled but will instead deliver his speech when the Parliament opens a month later on 24 August.

The following day, while Foreign Minister Vivian Balakrishnan held a meeting with Malaysian Foreign Minister Hishammudin Hussein at the Johor–Singapore Causeway, he mentioned on a separate interview that the assembly of the upcoming cabinet was a "complete unity" that balanced the components of continuity, exposure and renewal, and endorses Heng's leadership for the "fourth-generation" (4G) cabinet.

All 10 WP MPs also observed the inauguration that day but fielded into two teams of five, with the Aljunied GRC team attending at The Istana, and Sengkang GRC and Dennis Tan at the Parliament House. The following day, PM Lee announced that Singh would be entitled to additional parliamentary privileges and doubling his annual MP salary to S$385,000 as the leader of the opposition. Lee mentioned on a speech that there was an emerging trend that "shown a strong desire among Singaporeans for a greater diversity of views in politics", and its purpose on adding the role added was to "maintaining our cohesion and sense of national purpose". Previously, the title as a leader of the opposition was unofficial and paid the same reimbursement as a regular MP. When parliament held its first session on 31 August, Parliament also moved a motion allowing Singh to have double time (40 minutes) on making speeches, and entitled to hiring three legislative assistants and one secretarial assistant, as opposed to backbencher's one. Although WP lack candidates required to form a Shadow Cabinet due to the supermajority, Singh told that they would be scrutinising five key areas that were heavily concerned with (health, ageing and retirement adequacy; jobs, businesses and the economy; education, inequality and the cost of living; housing, transport and infrastructure; and national sustainability). Singh also told while delivering his maiden speech on three things: certain things that changed in Singapore, things that must not change, and things that should change, while described Singapore as a "glass half-full that can be topped up".

On 20 August, the parliament confirmed Tan Chuan-Jin will reprise his role as a Speaker of Parliament, while Fu and Lee were replaced by Rajah and Zaqy respectively, as the new leader and deputy leader for the upcoming parliament. Puthucheary and Sim were also reprised in their roles as Party Whip and deputy Whip respectively. On 31 August, both Christopher de Souza and Jessica Tan were elected as Deputy Speakers, replacing Charles Chong and Lim Biow Chuan.

Separately, the Government Parliamentary Committees (GPCs) were also announced with Vikram Nair, Liang Eng Hwa and Seah Kian Peng reprising their chairman roles, while Tin Pei Ling replacing retiring MP Cedric Foo as the deputy chairman for the Communications and Information GPC, and Sitoh Yih Pin, Patrick Tay, Desmond Choo, Tan Wu Meng, Saktiandi Supaat and Louis Ng as chairmen for the GPCs for Culture, Community and Youth, Education, Manpower, Health, Transport and Sustainability and the Environment, respectively. Most other roles for the GPCs were left untouched.

The 14th parliament opened on 24 August at 8 pm SGT, and similar to the cabinet inauguration, also for the first time in Singapore history, the parliament opened on separate venues due to safe distancing, both on the Parliament House and The Arts House, the latter being the venue of the former Parliament House before 1999. According to Rajah's Facebook post on the eve of opening, the fifth COVID-19 budget statement by Heng a week prior on the 17th was meant "the best option" and ensuring MPs, businesses and workers proper clarification on the Government's plans before the opening. During the opening, President of Singapore Halimah Yacob mentioned on her address that the start of the term was "under the shadow of COVID-19" with the situation "remain grave for some time", while the rise of the fourth-generation (4G) cabinet was meant "to take Singapore the next steps forward". Speaker Tan mentioned that the 12-member opposition representation along with Singh's role as the Leader of the Opposition was meant for "contestation", but warned about "polarisation and division" which could cause short-termism and populism if triggered.

On 2 September, Prime Minister Lee revealed on a live broadcast message in Parliament on the decision to open the 14th Parliament early, due to the urgency on dealing COVID-19 and the economy, while praising the current situation on mitigating the infection rate and healthcare, and mentioned that implementing a "Circuit Breaker" for two months was a big move and was successful.

The Ministry of National Development (MND) announced on 30 July that there were 17 town councils formed, with each town council formed from one GRC and at least one SMC in 11 out of 17 towns. Among which, Sengkang Town Council (SKTC) was brand new which was formed from the standalone Sengkang GRC, while 11 towns had changes in at least one of the areas due to redistricting and carving out divisions into SMCs, such as Ang Mo Kio Town Council (AMKTC) which was formed along with Kebun Baru SMC (transferred from Nee Soon Town Council (NSTC)) and Yio Chu Kang SMC, and Bishan-Toa Payoh Town Council (BTPTC) and Pasir Ris-Punggol Town Council (PRPTC) which were formed from its namesake GRCs and the newly carved Marymount SMC and Punggol West SMC, respectively. The boundaries for the five town councils were untouched from the last parliament term, namely Aljunied-Hougang (AHTC), East Coast-Fengshan (ECTC; renamed to East Coast), Holland-Bukit Panjang (HBPTC), Jurong-Clementi (JCTC) and Tanjong Pagar (TPTC), with the exception of East Coast GRC due to Fengshan SMC being absorbed into, four out of the five GRCs had experienced no boundary changes. 15 out of 17 towns were managed by PAP with the exception of AHTC and SKTC, which were managed by WP.

Under the Town Council Act, each town have until 28 October, 90 days from the date of the order issued, to effectively transfer services to the required towns applicable, though it can also mutually agree to an earlier date.

On 17 July, two weeks ahead of the announcement, He Ting Ru requested to manage their own Sengkang Town Council without any merging of other town councils as a chairwoman of the town council, and added that she also wrote to both AMKTC and PRPTC on 11 July to request a preliminary meeting to discuss the handover, as most of the divisions in Sengkang were under PRPTC in the last election, except Anchorvale, which is based on Sengkang West SMC (part of AMKTC).

On 20 July, a legal poser was also brought by the Pasir Ris-Punggol Town Council (PRPTC) citing that who would be the next plaintiff after the Sengkang ward was claimed by WP; SKTC contains a division (Rivervale) which was based on Punggol East SMC, a ward previously held by the WP between the 2013 by-election and the last election, and AHTC is currently facing a situation of civil lawsuit over a breach of duties and auditing problems worth over S$33 million, which WP had since lodged an appeal prior to the election. On 3 August, the High Court updated lawyer representatives for the AHTC applied amendments to the claims against previous town councillor Singh and four others in a case which was decided last year. The update found Singh and two others councillors, Kenneth Foo and Chua Zhi Hon, were in breach of their duties. According to Singh, the amended statement for which court approval was sought was meant to understand the proposed amendments, which Singh did not reply to a request for comment by press time. A hearing on the application was scheduled to be held in chambers before High Court Justice Ramesh Kannan that day. The defendants were notified by the High Court that the trial had ended and were given a judgement prior, as AHTC filed the lawsuit late in 2017, by then the town would have time to make the claims. In an oral judgment released by Justice Ramesh on 20 August, he mentioned the amendments that pertained to Singh, Chua and Foo were neither involved issues during the trial, and that amendment was sought to allow the three defendants to address any new claims, which is now before the Court of Appeal; however both lawsuits were tried but not consolidated. He ordered the parties to file submissions on costs within one week of the judgment.

On 22 August, the appeal was postponed under a request by He under SKTC to allow "sufficient time" to consider its legal status according to court papers, after she submitted a six-week adjournment on 10 August and explained references to the Town Councils (Declaration) Order 2020 and defended judgements of the court of appeal, added with sought of legal advice. The adjournment was approved by several law firms including the Davinder Singh Chambers.

Under the current constitution from the Parliamentary Elections Act, voting in the general election is mandatory and candidates who did not cast the vote are delisted from the Registrar of Electors at the end of voting. Including overseas voters, a total of 111,076 voters, which comprises 4.19% of the whole 2,651,435 electors eligible, did not cast the vote on 10 July.

On 5 October, the Election Department announces that the inspection of a list of non-voters were open to public and non-voters can restore their names at any time until the writ of election for the next election is issued. A $50 fee must be paid to reinstate the names, though it can be waived under approved reasons according to the Election Department; the exception is the 350 voters who were quarantined at the time of polling day as the names are automatically restored.

Under the act, all the ballots boxes are sealed and guarded under maximum security inside the vault located at the Supreme Court within six months upon the first locking until 16 January 2021, after which the ballot boxes are transported to Tuas South Incineration Plant for incineration, ensuring integrity and that the privacy of the electors are not compromised. Only a judge of the Supreme Court may have the order to open the sealed boxes and inspect the contents during the time, though it is to institute or maintain a prosecution or an application to invalidate an election.

While electors are allowed for inspection from the date onwards, only the voters who cast in Elias Park Primary School (PN23, or the 23rd polling district for the Pasir Ris-Punggol GRC, which encompasses voters from one of the Elias subdivision from Pasir Ris) are unable to do so until 10 January 2021 as a copy of the register of electors was among the documents sealed wrongly by an election officer. President Halimah Yacob approved the order of retrieving the document; while the ballot box is destroyed after the date, the destruction of the copy is delayed up till 9 February (maximum 30 days) upon its retrieval. The list for PN23 was made available on 25 January, with both PAP and Singapore Democratic Alliance (SDA) witnessing the event.

The number of people witnessing the incineration of boxes on 16 January were on limited capacity because of social distancing, among which members present include new MPs Yeo Wan Ling and Derrick Goh, and WP representatives Singh and Nicole Seah, and SDP's chairman Paul Tambyah.

On 8 November 2020, the 36th Central Executive Committee for the People's Action Party (PAP) was held. On an announcement, many members were re-elected in their roles, so were new members Edwin Tong, Alex Yam, Ng Chee Meng, and Victor Lye who were co-opted on 19 November. It also elected Desmond Lee and Grace Fu as Organising Secretaries, while Yam, Chee Hong Tat and Janil Puthucheary were elected as Assistant Organising Secretaries. The CEC also appointed Josephine Teo as the chair of the PAP's Women's Wing, Lee as the chair of the PAP Senior Group (PAP.SG), Puthucheary as the chair of the Young PAP (YP), and Lawrence Wong as the Advisor to PAP Policy Forum (PPF).

In a statement by Prime Minister and party's secretary-general Lee Hsien Loong, the change was meant to keep this cycle going for as long as possible and along with the prior election results. Lee noted on countries that have fiercely contested democratic systems but was not perfect, leading to contestation that often causes politics unstable and divided, with those in power focusing only on their own short-term political survival, and those out of power offering remedies without being upfront about the costs and consequences. Lee stated that the party will need to work even harder to build consensus and create the political space for the future of Singapore during a turbulent and uncertain future.

Similarly, Workers' Party (WP) also held a biennial CEC election on 27 December at Clarke Quay instead of the headquarters at Geylang. Party chairman Sylvia Lim and Secretary-General Pritam Singh were re-elected in their respective posts, so were elected MPs Faisal Manap, Gerald Giam, Leon Perera, Dennis Tan and former MPs Low Thia Khiang and Png Eng Huat. All four Sengkang GRC MPs as well as Nicole Seah and Kenneth Foo were included in the list, replacing outgoing CEC members Firuz Khan, Dylan Foo, Terrence Tan and John Yam, as well as former MPs Chen Show Mao, Daniel Goh and Lee Li Lian.

Singh mentioned it was important for the party to retain some of its most experienced members like Low, who has been with the party since the early 1980s, especially the need of a younger cohort. Lim told on the media on her re-election that the party would continue to be mentored by the older cohort while entering a phase of renewal and growth for the next generation of leaders.

On 22 December, Jose Raymond stepped down as the chairman for the Singapore People's Party and retires from politics, so was the Assistant Secretary-General, Ariffin Sha, who also resigned from the party earlier in August. These resignations were accepted on 17 January 2021, and co-opted two new members, Osman Suliaman from the Reform Party, and Melvyn Chiu from the defunct Singaporeans First. The party's vice-chairman Williiamson Lee served as acting chairman, but no replacement was filled for the Assistant Secretary-General post and was left vacant.

On 28 March 2021, Progress Singapore Party held its CEC election with 11 members stepping down and 6 new members elected. On 1 April, Francis Yuen took over as Secretary-General of the Party with Tan Cheng Bock being chairperson.

On 5 August, Reform Party (RP) was the first to held a CEC renewal after the elections ended. RP's secretary-general Kenneth Jeyaretnam appointed Charles Yeo and Mahaboob Batcha (a businessman) as the new party's Chairman and Treasurer respectively, as part of the party's leadership renewal.

Former chairman Andy Zhu shortly posted on Facebook that he was unfairly dismissed by the party before allegations made against him by Jeyaretnam have been resolved and told that it was an "undemocratic stance". Jeyaretnam earlier had made changes to the party's payment methods without official approval, requiring all cheques for payments to be signed by the treasurer and one member from the CEC; Zhu said he had applied for Paynow and reactivated the party's online banking account, because of the need to quickly make full payment to contractors for services such as printing posters and distributing fliers, but Jeyretnam was accused on making payments to contractors using the wrong channels; he also mentioned the move was unfair and disputed Jeyaretnam's claim about the CEC's unanimous decision to suspend the duties for him and former Treasurer Noraini Yunus. However, Jeyaretnam added that the duo still have the opportunity to appeal the decision at a later time, and the post was taken down as the CEC has yet to deliberate the issues and makes a decision to appoint members of the CEC.

The seven members, including Zhu and Yunus, subsequently resigned from RP and formed a splinter party named Singapore United Party, with Zhu being the party's secretary-general. The party was registered to the gazette on 24 December. Osman Suliaman was among the members who resigned, but joined the Singapore People's Party instead.

The police arrested Lim Song Huat, a 48-year-old part-time security officer, for destroying election posters along with his accomplice Constantine Paul, 51, on 3 July, after police reports were first lodged on 1 July by both PAP and PSP. Lim faced three charges for vandalism, all for vandalizing three posters at Woodlands Street 13 reported at about 9:30 am on 3 July, while Paul was charged twice, each for vandalizing a poster at Bukit Batok East Avenue 5 and one of the PAP's team posters for Aljunied GRC. Lim was arrested by the Woodlands Police Division the following day after a closed-circuit television (CCTV) managed to record a footage of Lim vandalizing the post.

On 4 February 2021, the court fined Lim S$1,000 for a charge of vandalism, making it the first case of such kind a person was charged. Two other similar charges were taken into consideration. Paul, who also faces charges under the Act, is expected to plead guilty on 5 April.

Under Act 78A of the Parliamentary Elections Act, it is illegal for people attempting to vandalize and destroy election posters or banners, with each charge carrying a S$1,000 fine or a year imprisonment, or both. According to Deputy Public Prosecutor Selene Yap who foresees the case, she asked for the maximum fine of S$1,000, citing difficulties on detection as the posters were placed in public areas across Singapore.

The police arrested Sirajudeen Abdul Majeed, 52, for his racist remarks received on a WhatsApp message group, PSP MM Ground Group. Few weeks leading to the election on 12 June, the group was used to share information pertaining the election, but Sirajudeen purportedly received an image that have information of voters of racial groups living in Marymount SMC, which he studied without verifying the data with any official sources. Elections Department revealed that the distribution was not published publicly and its polling district boundaries depict in the image were not accurate. The following day at 1:50 pm, Sirajudeen shared the image to three men and encouraging to share it, commenting "the PAP wants to make the Malay community a sub-minority. But the Malays were the original residents of Singapore." and another comment that also included foreign immigrants. One of the people receiving the message, Mohammad Azri, immediately lodged a police report, which he explained that it "create awareness of what he perceived to be a strategy". Sirajudeen was again called by the police on August for another racial indecency, this time involving a dispute against his neighbors, in return he lodged two police reports citing "criminal harassment" and calling Malay "unprofessional" in terms on entering elite forces such as the Singapore Air Force.

Deputy Public Prosecutors Ng Yiwen and Tessa Tan, throughout the investigation, mentioned that Sirajuddeen's move was "to stoke fears that the PAP Government was seeking to marginalise the Malays in the country by allowing more immigrants into the country", adding that it was posted on a critical timing and the fear-mongering could have affected the foundation of multi-racism. Sirajudeen pleaded for mercy and leniency, adding that he was his family's sole breadwinner and has a child with special needs; in return, the judges ruled that these remarks could create friction and conflict between different races in Singapore, which cannot be taken lightly in the current security climate. Court documents also ruled that it did not mention whether PSP referred to the Progress Singapore Party, which the party also contested Marymount SMC.

On 8 February 2021, the court ruled Sirajudeen guilty of a charge of ill-will and slandering racial groups that intend to harm racial feelings and was jailed for two weeks and fined S$7,000; Sirajudeen took a $5,000 bail and is expected to begin his imprisonment by before 22 February. Two charges promoting enmity were currently taken in consideration. Penalties under Section 298A of the Penal Code under racial enmity carries a maximum three years imprisonment or a fine, or both.
