Singapore extends the CORENET X qualifying period for the developer ABSD remission timeline extension to September 2026 and September 2027

The 3 September 2025 change expanded the qualifying window; the existing 6-month extension to each of the ABSD remission commencement, completion and sale timelines remained unchanged.

Guidance and release, not statute. A statement of continuity: these are not six additional months introduced in September 2025; the 6 months was already in the 5 March 2025 release. Register ADJ-CX-2023, add months 6, on base rules rule 3(2)(c) commencement and rule 3(2)(d) completion and sale. For private residential projects of licensed housing developers only, granted on application (claim 10).

The project must have at least 6 months of its 2-year commencement timeline left when its first submission is made under CORENET X.

Guidance and release, not statute. Register ADJ-CX-2023, the third criterion, unchanged on 3 September 2025. It is 6 months of the base 2-year timeline, measured at the first submission. The 5 March 2025 release gives the worked case: a commencement timeline ending 31 December 2025 needs a first submission before 1 July 2025. This is where the land acquisition date enters, because it starts the commencement timeline.

A CORENET X help centre article created on 7 January 2026 states that the project completion period is extended by 6 months for qualifying projects on Government sale sites, on land directly alienated or lease-renewed by SLA, and under the qualifying certificate regime, where the project goes entirely through CORENET X and makes its first Design Gateway submission by 30 September 2026 or 30 September 2027, by GFA.

Guidance, not statute, later corroboration. Register ADJ-CX-PCP, on base rules GLS-PCP and QC-COMPLETION. Partially verified because the text is four months later than this event: what the article says is verified, but no text of September 2025 on the PCP extension is held, so whether its window moved on 3 September 2025, and whether its criteria were published then, is not established. The Minister named a PCP extension as already introduced on 23 January 2025. The article states two criteria and no 6-months-left test; whether one applies is not stated, and none is added here. It covers commercial and industrial projects as well.

Each window's closing date moved 9 months later: 31 December 2025 to 30 September 2026, and 31 December 2026 to 30 September 2027.

Release, arithmetic here. No source states the 9 months. Each move is 273 days, or 9 calendar months from month end to month end. The extension itself stayed at 6 months. No source links the new closing dates to the mandatory CORENET X dates, and none is drawn here.

The project's first submission at the Design Gateway under CORENET X determines the window test; the applicable acquisition date, which starts the 2-year commencement timeline, remains relevant to the 6-months-left test.

GUIDANCE. Register ADJ-CX-2023, trigger first corenet x submission date. IRAS asks for the acknowledgment email bearing the date of the first Design Gateway submission. Land bought before 3 September 2025 is not shut out by the window test, but a purchase early enough to leave less than 6 months of the commencement timeline at the first submission fails claim 8.

Under the published window, first submissions after 30 September 2026 for projects of 30,000 sqm GFA or more, and after 30 September 2027 for smaller projects, fall outside this measure; that is window version V3 as published and observed on 27 September 2026.

Guidance, on living pages observed on 27 September 2026. No structured value: dates, not quantities. Register ADJ-CX-2023, window version V3. The help centre calls it "a time-limited extension" in an article last edited on 7 January 2026. A later version of the window would change the dates. Nothing held says a project that qualified in time loses its extension when the window closes.

Calculated on the base timelines in rule 3(2) of the remission Rules, each counted from the date of execution of the land instrument, a project confirmed for the extension would have 2 years and 6 months to commence and 5 years and 6 months to complete and to sell all units. This is a calculation under those baseline and starting-date rules, not a deadline for any project.

Statute for the base, guidance for the extension, arithmetic here. No structured value: three derived periods. Derivation: base 2 years, 5 years and 5 years, each plus 6 months. Assumptions: the unreplaced periods of rule 3(2)(c) and (d) apply, and the clock starts on the land instrument's date, not on the first submission. A project on a replaced period under rule 3(2A) to (2C), or with another extension, has a different baseline, so its own base timeline, instrument date and confirmation must be established before a deadline is returned. No source prints the extended CORENET X periods. The documents deadlines in rule 3(2)(e) and (f) are not named in the extension, and none is asserted to move.

The project must go entirely through the CORENET X approval process for building works, submitting and securing clearance at the Design and Construction Gateways.

Guidance, not statute. Register ADJ-CX-2023, the first of three criteria, unchanged on 3 September 2025. A project that moves part of its building works approvals outside CORENET X does not meet it.

A developer seeking the extension approaches URA's project facilitators with documents showing the criteria are met, such as the acknowledgment email dating the first Design Gateway submission and URA's Provisional Permission and Written Permission.

Guidance, not statute, undated. Register ADJ-CX-2023, mode APPLICATION. Using CORENET X does not by itself extend any timeline: the developer applies and shows the criteria are met. No held source says the extension is automatic, and none gives a processing time for a CORENET X application.

The CORENET X extension cannot be combined and added to the extensions granted for complex projects.

Guidance and release, not statute. Register STACK-CORENETX-COMPLEX, stackable NO. Neither source says which extension applies when a project qualifies for both, or whether the developer chooses. The release ties the rule to its four categories of 5 March 2025; the IRAS page, which now also lists the en bloc Categories 1A and 1B of July 2026, says "complex projects" without qualification.

The same later help centre article says the PCP and ABSD are two separate regimes and that PCP extension requests are assessed independently from ABSD remission extensions, with queries to the land sales agents, SLA's Land Transfer and Land Sales Division, or SLA's Land Dealings Approval Unit for qualifying certificate sites.

Guidance, later corroboration, created 7 January 2026. Register STACK-CORENETX-ABSD-PCP, stackable INDEPENDENT. Partially verified because whether this procedure was published in September 2025 is not established by anything held. On the article's terms an ABSD extension does not bring a PCP or qualifying certificate extension with it, and the reverse holds too. The land sales agents named are URA, HDB and JTC.

A calculation on stated assumptions finds no project on a COVID-19 replacement period that could meet the 6-months-left test at a first submission in the window; no source addresses the combination, and this is not a rule against combining the two reliefs.

Statute and guidance, derived here, not stated by any source. Register STACK-COVID-CORENETX. Assumptions: the test is measured on the project's commencement timeline as the Rules set it; the window opens on 18 December 2023; the replacement periods reach instruments dated up to 7 May 2021. Calculation: the latest replaced commencement deadlines are an instrument of 1 June 2020 plus 3 years and 6 months, and one of 7 May 2021 plus 2 years and 6 months, both in late 2023 and before 18 December 2023, so no time is left at any first submission in the window. On the unreplaced 2-year timeline a project needs a land instrument dated about mid-June 2022 or later to have 6 months left on 18 December 2023; the register's day count gives 19 June 2022, so the result holds on either reading. If a case meeting both ever arose, no source says how they would combine.

Where an extension applies, IRAS says the proportion of units sold for the Budget 2024 lower clawback rates is assessed at the end of the extended sale timeline; the other conditions for those rates still apply.

Guidance, undated. No structured value: the digits name Budget 2024 and a condition this measure did not set. Register NOTE-GRADUATED-AT-EXTENDED-SALE. This claim concerns the assessment date only. An extended project does not qualify for the lower rates by being extended: at least 90% of units must be sold by the end of the sale timeline, and the commencement and completion timelines must also be met. The FAQ sits under complex projects but speaks of the extended timelines generally.

For a project with a GFA of 30,000 sqm or more, a first submission made from 18 December 2023 to 30 September 2026 inclusive meets the submission-window condition for the CORENET X extension, subject to the other requirements; before 3 September 2025 the window closed on 31 December 2025.

Guidance and release, not statute. No structured value: the moved parameter is a cut-off date. Register ADJ-CX-2023, window version V3. The date is the last day for the first Design Gateway submission, not for commencing works or buying land. Meeting the window is one condition of three: claims 7 and 8 set the others, and claim 10 the application. The 30,000 sqm line did not move.

For a project with a GFA of less than 30,000 sqm, a first submission made from 18 December 2023 to 30 September 2027 inclusive meets the submission-window condition, subject to the other requirements; before 3 September 2025 the window closed on 31 December 2026.

Guidance and release, not statute. No structured value: a cut-off date. Register ADJ-CX-2023, window version V3. IRAS gives the opening date and "inclusive"; the factsheet gives the old and new closing dates. As for claim 1, the window is one of three criteria.

IRAS dates the extension of the qualifying period to an announcement on 3 September 2025.

Guidance, on a living page observed on 27 September 2026. No structured value: the only digits are the date. The quote is IRAS's note and is cited to the IRAS page only. The factsheet's parent media release and the Minister's IBEW dinner speech, which may carry the announcement, were not read, so the date rests on IRAS's statement alone.

As announced by BCA and URA on 23 January 2025 and restated in the factsheet, CORENET X submission was to become mandatory for new projects of 30,000 sqm GFA or more from 1 October 2025 and for all new projects from 1 October 2026, and all ongoing projects were to be onboarded from 1 October 2027.

Guidance (a bca and URA circular), not statute. No structured value: dates. The timetable as announced at the time; on 3 September 2025 all three dates were still ahead. A later revision of the timetable is reported but no text of it is held, so no revised date is stated here. The circular does not mention ABSD, PCP or stamp duty; the dates are context for the windows, not part of the extension. A new project is one that has not begun a planning or development control application.

In the factsheet issued with the announcement IRAS dates to 3 September 2025, BCA said more than 50 projects involving 100 firms had made voluntary CORENET X submissions since the soft launch on 18 December 2023, a count at that time rather than a current figure.

RELEASE. No structured value: "more than 50" is a floor, not a count. The factsheet carries no date of its own (claim 4), so the count is attributed to the factsheet and to the announcement date IRAS gives, and is not displayed as current adoption. It covers all building types, not residential projects only, and is not a count of ABSD extensions granted.

BCA said the extended eligibility window would give the industry added assurance while it adjusts to CORENET X processes and digital tools.

RELEASE. Verified as a statement the Government made, not as a finding. Paragraph 14 gives the reason for the original extension as the industry's concern that a transition period was needed.

In the copy retrieved on 27 September 2026, the BCA factsheet that states the extension carries no date on its face.

Release, observed, not stated by the source. An absence found in one copy, so it earns no more than partly verified. It does not show that no dated version exists: the factsheet is an annex to a BCA Awards 2025 media release that was not located. The date of the extension is IRAS's (claim 3), not read off this document.

The original qualifying window ran from 18 December 2023 to 31 December 2025 for all projects; its announcement is not held, and the window is known from the 5 March 2025 release's statement of the position then current.

Release, not statute, stating an earlier position. No structured value: dates. Register ADJ-CX-2023, window version V1. Verified as the release's statement of what applied "currently" on 5 March 2025. The original announcement is not held, and no date is given for it here.

On 5 March 2025 MOF and MND revised the window: it would cease for new projects of 30,000 sqm GFA or more whose first submission was made after 31 December 2025, and was extended for smaller projects to first submissions made until 31 December 2026 inclusive.

Release, not statute. No structured value: dates. Register ADJ-CX-2023, window version V2. The step is the published event of 5 March 2025; the factsheet restates the two closing dates.

On 3 September 2025, the date IRAS gives, the window was further extended from 31 December 2025 to 30 September 2026 for projects of 30,000 sqm GFA or more, and from 31 December 2026 to 30 September 2027 for smaller projects.

Release and guidance, not statute. No structured value: dates. Register ADJ-CX-2023, window version V3. The text is BCA's and undated (claim 4); the date is IRAS's (claim 3).

On 23 January 2025 the Minister for National Development said the Government had introduced a six-month extension to ABSD remission and PCP timelines to give practitioners more time to learn the new processes.

Release (a ministerial speech). No structured value: the only digits are the date. The earliest dated official mention held, in the past tense. The original announcement, with the window opening on 18 December 2023, is not held, and no date is given for it here.
