Key numbers

In brief

On 19 February 2018 the Minister for Finance announced in Budget 2018 that the top buyer's stamp duty rate on residential property would rise from 3% to 4%, charged only on the part of the value above S$1 million, for property acquired from the next day. Nothing changed for a purchase at or below S$1 million, and non-residential property kept its old schedule. Options granted by 19 February 2018 kept the old rates if exercised by 12 March 2018 or within their validity, whichever came first.

Why it mattersInterpretation

A marginal rate, not a rate on the whole price

The 4% is charged on the portion above S$1 million. A S$1.5 million purchase pays it on S$500,000 and the lower bands on the first S$1 million, exactly as before. Headlines reading "4% stamp duty on homes above S$1 million" describe a tax the release does not impose, and the error grows with price, because it applies the higher rate to the first S$1 million as well.

The first split between residential and non-residential buyers

Until 20 February 2018 one schedule covered every property. The release left non-residential property at 1%, 2% and 3% and moved only residential, so the property class became a rate parameter. That split is what the February 2023 revision later built on, when both classes gained higher bands on different thresholds.

For agents

A buyer above S$1 million pays an extra 1% of the excess and nothing more. The number to give a client is the excess times 1%, not the price times 1%, and a buyer at or below S$1 million faces no change at all.

What changed

A fourth band was added at the TOP. Residential property acquired on or after 20 February 2018 pays 1% on the first S$180,000, 2% on the next S$180,000, 3% on the next S$640,000 and 4% on everything above S$1,000,000. Before, the 3% band ran without limit above S$360,000. The rate on the first S$1 million did not move, so the change reaches only the part of a purchase above that figure, at a rate one percentage point higher than before. Non-residential property stayed at 1%, 2% and 3%, which split the two classes onto different schedules for the first time. The Option to Purchase provision kept pre-announcement options on the old rates for up to three weeks, and the release stated that the additional conveyance duties would be adjusted to match, without giving the rates.

Instruments and scope
Residential property in Singapore acquired on or after 20 February 2018, on the portion of the purchase price or market value that exceeds S$1,000,000. Non-residential property is outside the measure and keeps its 1%, 2% and 3% schedule.

Before this framework
Before 20 February 2018 every property, residential or not, paid buyer's stamp duty on the same bands: 1% on the first S$180,000, 2% on the next S$180,000 and 3% on the amount exceeding S$360,000. The 3% band had no upper limit, so 3% was the rate on every dollar above S$360,000 however large the purchase. The duty was charged on the actual price or market value.
Positioning at introduction
Announced by the Minister for Finance in the Budget Speech of 19 February 2018 as a rise in the top marginal buyer's stamp duty rate from 3% to 4%, applied on the value of residential property in excess of S$1 million. The Ministry of Finance release that followed gives the revised bands and a transitional provision and states no market objective.
Current status
Amended. Residential BSD, top marginal rate changed 15 February 2023; Non-residential BSD changed 15 February 2023.

Market context

We've seen this before

5 July 2018 · 6 July 2018

Singapore raises ABSD by 5 to 10 points and tightens LTV limitsSame year, different instrument

Why relevant

The other stamp duty change of 2018, and the one most likely to be confused with this one. Both raised a duty paid by buyers of residential property within five months of each other, and a reader searching for 2018 stamp duty will find both.

Where the comparison breaks

  • February 2018 moved buyer's stamp duty, which every buyer pays by value band. July 2018 moved additional buyer's stamp duty, which depends on the buyer's residency and the number of properties held, and also cut loan-to-value limits.
  • February 2018 was a Budget measure from the Ministry of Finance alone and states no market objective. July 2018 was a joint package presented as promoting a stable and sustainable property market.
  • February 2018 reached only the value above S$1 million and left every smaller purchase unchanged. July 2018 reached buyers by class regardless of price.

What happened after

July 2018 cuts short any outcome window for this event. From 6 July 2018 two stamp duties and the loan limits moved together, so nothing observed after that date can be attributed to the February band alone.

Not a precedent for: Additional buyer's stamp duty (ABSD); Seller's stamp duty; Credit instruments such as loan-to-value limits, TDSR and MSR; Non-residential buyer's stamp duty; Annual property tax

20 February 2018 to 5 July 2018

Bunching of residential purchase prices just below S$1 million

Show detail
CALENDAR · 20 February 2018 to 5 July 2018Residential property, Singapore

Interpretation

A marginal band adds only 1% of the excess above S$1 million and leaves the duty at S$1 million untouched, so it gives no reason to price a unit just under the threshold. The test is whether residential caveats priced just below S$1,000,000 rose as a share of the market after 20 February 2018 relative to 2017, beyond the usual clustering at round prices. A visible excess would show the band being treated as a cliff.

Why this grade

No grade is assigned because no price distribution is held in this archive. The window closes on 5 July 2018, because the July 2018 measures changed additional buyer's stamp duty and loan limits from 6 July 2018 and any comparison after that date mixes the two.

No caveat price distribution is loaded here. The window is also cut short by the July 2018 measures.

CALENDAR · 19 February 2018 to 12 March 2018 · FROM ANNOUNCEMENTResidential property above S$1 million, Singapore

Interpretation

Holders of options granted by 19 February 2018 on properties above S$1 million had a reason to exercise inside the three-week window. The test is whether exercises in those weeks ran above the same weeks of 2017. No rise would suggest a 1% increment on the excess was too small to move timing.

Why this grade

No grade is assigned because option-exercise dates are not held here, and the effect, if any, is bounded by the size of the increment on each purchase.

No option-exercise series is loaded in this archive.

CALENDAR · FY2018 onwardResidential property, Singapore

Interpretation

The direct measure of the band would be the duty it raised. IRAS does not publish buyer's stamp duty collections by band, so the measure cannot be tested on its own fiscal terms. Recorded so the absence is visible rather than assumed.

Why this grade

Not gradeable. Aggregate stamp duty collections mix every stamp duty, every property class and every price band, and would not isolate this one.

No band-level collection series exists in public data known to this archive.

Prevo analysis

Prevo view

Interpretation

A small, well-targeted change whose main significance is structural. The fiscal increment is 1% of the excess above S$1 million and reaches no one below it, so it was unlikely to move prices on its own, and nothing in this archive can show that it did. What lasted was the split: from this date residential and non-residential property sat on different schedules, and the 2023 revision extended both along separate thresholds. Read as a cooling measure it is weak; the release does not present it as one.

Confidence: MEDIUM

What would change this view: A band-level count of residential purchases above S$1 million, or the duty collected in the 4% band, would show whether the increment reached a material share of the market. A visible cluster of prices just under S$1 million in early 2018 would show buyers treating the band as a cliff, which the design does not justify. A government-hosted copy of the Budget Statement would put the Government's own rationale on the record.

The case for and the case against2

The case for

The measure raises the duty only where the value is highest, leaves the first S$1 million of every purchase untouched and reaches no non-residential buyer. A marginal band avoids a cliff at the threshold, so it gives no reason to price a unit just under S$1 million. The transitional provision protected buyers who had already been granted an option, with a fixed outer date.

The case against

The increment is small: 1% of the excess above S$1 million. The release gives no objective, no estimate of revenue and no count of the purchases affected, so the measure cannot be tested against its own stated purpose because none is stated. Its effect on prices or volumes, if any, cannot be separated from the July 2018 measures, which changed additional buyer's stamp duty and loan limits less than five months later. And the adjustment to the additional conveyance duties is announced without rates, so part of the package is not on the record held here.

What this view assumes4
  • The residential schedule from 20 February 2018 is 1% on the first S$180,000, 2% on the next S$180,000, 3% on the next S$640,000 and 4% above S$1,000,000.
  • The 4% applies only on the portion of value above S$1 million.
  • An option granted on or before 19 February 2018 kept the old rates only if exercised on or before 12 March 2018 or within its validity, whichever was earlier.
  • Non-residential rates stayed at 1%, 2% and 3%.
What we don't know4
  • The number and share of residential purchases above S$1 million in 2018
  • The duty raised by the 4% band
  • The adjusted additional conveyance duty rates
  • The Government's stated rationale, held only through a third-party capture of the Budget Statement

Rates, figures and counts7
  1. Claim 1

    The top marginal buyer's stamp duty rate for residential property was raised from 3% to 4%, charged on the portion of value above S$1 million.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, paragraph 1 and Annex, row "4% (New)"; IRAS, "Buyer's Stamp Duty (BSD)", rates and computation, table for 20 February 2018 to 14 February 2023]

    A marginal rate, not an effective one. The 4% applies on the portion above S$1 million and on nothing below it, so a S$1.5 million purchase pays 4% on S$500,000 and the lower bands on the rest. Residential property only, acquired on or after 20 February 2018, subject to the Option to Purchase provision in claim 3. The non-residential top rate stayed at 3%.

  2. Claim 2

    A new 4% residential band applies on the portion of value above S$1,000,000, that is S$1 million; the annex records a 4% rate as previously not applicable.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, Annex, row "4% (New)", residential column and the tiers-before column reading "Previously not applicable"]

    A new band, so no before-value is stored and none is invented. The threshold is where the 4% starts, not a price at which a buyer becomes liable to the higher rate on the whole value: a purchase at S$1,000,001 pays 4% on one dollar. Residential property only.

  3. Claim 3

    Where an Option to Purchase was granted on or before 19 February 2018, the old rates applied if the option was exercised within three weeks of the announcement, that is on or before 12 March 2018, or within the option's validity period, whichever was earlier.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, paragraph 2 under "Transitional Provision"]

    The earlier of two limits. An option whose validity ended before 12 March 2018 had to be exercised by its own expiry to keep the old rates. Covers options granted by sellers to potential buyers on or before 19 February 2018. The release does not define the date of acquisition beyond this provision.

  4. Claim 4

    The 3% residential band, which had applied to all value above S$360,000, was capped at the next S$640,000, so that it runs from S$360,000 to S$1,000,000.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, Annex, row "3%", residential column reading "Next" S$640,000 "(Revised)", against "Amount exceeding" S$360,000 in the tiers-before column]

    The rate did not move, only the width. Value between S$360,000 and S$1,000,000 pays 3% exactly as before. No before-width is stored, because the old band had no upper limit and an unbounded width has no numeric form.

  5. Claim 5

    The 1% band on the first S$180,000 of a residential purchase was unchanged.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, Annex, row "1%", residential column, marked "(No Change)"]
  6. Claim 6

    The 2% band on the next S$180,000 of a residential purchase was unchanged.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, Annex, row "2%", residential column, marked "(No Change)"]
  7. Claim 7

    Buyer's stamp duty on non-residential property was unchanged at 1% on the first S$180,000, 2% on the next S$180,000 and 3% on the amount exceeding S$360,000, with no 4% band.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, Annex, column "Non-Residential Properties (No Change)"; National Archives copy of the same release, where the 4% cell reads "Not applicable"]

    The stored pair is the top non-residential rate. From 20 February 2018 residential and non-residential property carried different schedules for the first time. The IRAS guidance page lays out its 2018 to 2023 non-residential column ambiguously when transcribed, so this claim rests on the release, where the MOF page truncates the last cell and the archived copy shows it whole.

Rules and scope2
  1. Claim 9

    Buyer's stamp duty is charged on the actual price or market value of the property, whichever is higher, according to the date of acquisition.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, Annex, first column heading; IRAS, "Buyer's Stamp Duty (BSD)", rates and computation, first sentence]

    The release says "actual price or market value"; the words "whichever is higher" are the IRAS page's. Unchanged by this measure.

  2. Claim 10

    The release stated that the additional conveyance duties rates would also be adjusted accordingly, without stating the adjusted rates.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, Annex, footnote 1]

    The footnote states a direction only. No rate, instrument or wording for the additional conveyance duties is given, and this archive holds none. Additional conveyance duties are not additional buyer's stamp duty, and the footnote says nothing about ABSD.

Dates1
  1. Claim 8

    The revised rates apply to all residential properties acquired on or after 20 February 2018.

    VERIFIED PRIMARY[MOF press release, 19 February 2018, paragraph 1, second sentence]

    The trigger is the acquisition date, and the release does not define it. The Option to Purchase provision in claim 3 is the only refinement it states.

Characterisations and comparisons1
  1. Claim 12

    Because the 4% applies only on the portion above S$1 million, the revision leaves the duty on any residential purchase at or below S$1 million unchanged and adds 1% of the amount above S$1 million to the duty on a larger one.

    PARTIALLY VERIFIED[Prevo reading of the bands in the MOF press release, 19 February 2018, Annex]

    The inputs are primary and the reading is prevo's. Every band it rests on is in the release, and the arithmetic follows from them, but the release itself states no duty on any price and works no example. So this is stored as interpretation and not as a policy fact, and no duty figure on a specific price is published from it.

Background1
  1. Claim 11

    IRAS records the buyer's stamp duty rate as up to 3% before 20 February 2018 and the rate for residential property acquired from 20 February 2018 to 14 February 2023 as up to 4%.

    VERIFIED PRIMARY[IRAS, "Buyer's Stamp Duty (BSD)", rates and computation, second paragraph, retrieved 26 September 2026]

    A later reading that bounds the 2018 schedule in time. It is carried so that the 4% top rate is never displayed without the date its band was narrowed; the later schedule belongs to the February 2023 event, not to this one.

How this is scored

Counts are by provenance, meaning who established the claim, not by how confident we are. A policy fact is one the regulator's own document states. A market observation comes from a named data series. A derived calculation is one we computed, with the working recorded on the claim.

Interpretations are counted, never netted out. This page will not display zero unsupported claims while interpretive sections sit outside the claim ledger, because that number would be true only by excluding the material most likely to be wrong.

A claim of one type is only treated as verified by a source of the matching type. A market observation is not verified by a regulator press release.

Claims are grouped by the type recorded on each one. Grouping hides nothing: every claim is in exactly one group, in full.
