Additional Buyer's Stamp Duty (ABSD) is the tax that catches the most Singapore property buyers off guard — and the one where a single timing decision can cost or save hundreds of thousands of dollars. After 200+ landed transactions and years guiding upgraders, I can tell you that most ABSD “mistakes” are not about the rates at all; they are about sequence and structure. This guide covers both.
What ABSD is and when it applies
ABSD is a stamp duty charged on top ofthe standard Buyer's Stamp Duty (BSD) when you buy residential property. It is calculated on the higher of the purchase price or market valuation, and it is payable within 14 days of signing the Sale and Purchase Agreement or exercising the Option to Purchase. The rate you pay depends on two things: your residency/profile and the number of residential properties you already own.
Current ABSD rates (2026)
The prevailing ABSD rates following the latest cooling measures are:
- Singapore Citizens: 0% on the first property, 20% on the second, 30% on the third and beyond.
- Singapore PRs: 5% on the first property, 30% on the second, 35% on the third and beyond.
- Foreigners: 60% on any residential purchase.
- Entities / trusts: 65% (with an additional non-remittable component for trusts).
Notice the cliff: for a citizen, going from a first to a second property jumps from 0% to 20%. On a $2 million home that is $400,000. This is why the order in which you buy and sell matters more than almost any other decision in your transaction.
How property count is determined
Your “count” is the number of residential properties you hold an interest in at the moment you commit to the new purchase — including overseas? No, ABSD counts Singapore residential propertiesyou own or partly own, including a share inherited or held jointly. A 1% share still counts as owning a property. This trips up buyers who co-own a parent's flat or hold a small stake in a family property.
ABSD remission for married couples
The most important relief: a married couple where at least one spouse is a Singapore Citizen can buy a replacement home, pay the ABSD up front, and claim a full refund— provided they sell their existing property within the prescribed window (6 months of the new purchase for a completed property, or within 6 months of the new property's completion/TOP if it is under construction) and the couple owns only the one new property after the sale. Both names must be on the new purchase.
Miss the deadline by even a day and the refund is forfeited. I have seen couples lose six-figure refunds because a buyer for their old flat fell through at the last minute. If you are going down the buy-first route, the exit plan for your current home has to be as solid as the purchase itself.
Sell-first vs buy-first: the ABSD decision
For most upgraders the cleanest path is to sell first. Once you own zero residential property, your new home is a first property and there is no ABSD to pay or reclaim. The trade-off is a possible interim rental. Buy-first avoids the double move but exposes you to the remission deadline and a large temporary cash outlay. Neither is universally right — it depends on your cash position and the market.
Decoupling — and why it is now rarely worth it
“Decoupling” — transferring one spouse's share of a property to the other so that the freed-up spouse can buy again as a “first-timer” — used to be a popular ABSD-avoidance route. It still exists, but BSD on the transfer, legal costs, and refinancing usually erode the benefit, and it does not work for HDB flats in the same way. Treat any decoupling pitch with caution and run the full numbers before assuming it saves money.
ABSD for foreigners and entities
At 60%, foreigner ABSD has materially cooled overseas buying — though citizens of certain countries with Free Trade Agreements (such as the USA, and nationals of Switzerland, Liechtenstein, Norway and Iceland) may be accorded the same treatment as Singapore Citizens under the respective FTAs. Entity and trust purchases at 65% are now almost entirely the domain of genuine development or specific structuring, not ordinary buyers.
Worked example: a typical upgrader
Say a citizen couple owns an HDB flat worth $700,000 and wants a $2 million condo. If they buy first without remission planning, they face 20% ABSD = $400,000 up front. If they sell their flat first, ABSD is $0. If they buy first with proper remission and sell within the window, they pay the $400,000 then reclaim it — but they must fund it in the meantime. The strategy chosen here is worth more than any discount they could negotiate on the condo itself.
How to plan your ABSD position
- Confirm exactly how many residential properties you (and your spouse) hold an interest in.
- Decide sell-first vs buy-first deliberately, with the cash flow modelled.
- If buying first, diarise the remission deadline and line up your sale before you commit.
- Get the BSD + ABSD + downpayment total in writing before you view, so your budget is real.
Get your ABSD position checked before you commit
ABSD rules are unforgiving, and the cost of getting the sequence wrong dwarfs almost anything else in your purchase. As Senior Director of Agency at ERA Realty Network (CEA Reg No. R045215J), leading the #KND team of 400+ agents, I map every client's ABSD and remission position before a single viewing. If you are planning a purchase or an upgrade in 2026, message me first and we'll structure it properly.
