Singapore ABSD Calculator: Additional Buyer's Stamp Duty
Work out the Singapore ABSD (Additional Buyer's Stamp Duty) on a residential property purchase — the extra duty that depends on your buyer profile and how many properties you own — on top of the standard Buyer's Stamp Duty.

Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Additional Buyer's Stamp Duty | Price after ABSD |
|---|---|---|
| 20% of $1,000,000 ($200,000) | 200,000 | 800,000 |
| 60% of $1,500,000 (foreigner) | 900,000 | 600,000 |
| 5% of $800,000 (PR, first home) | 40,000 | 760,000 |
| 30% of $1,200,000 (Citizen, third) | 360,000 | 840,000 |
How This Calculator Works
Enter the ABSD rate for your profile and the property price (or market value, whichever is higher). The calculator returns the ABSD payable and the price net of it. ABSD is a cooling measure: it's charged in addition to the Buyer's Stamp Duty (BSD) that every buyer pays, and the rate rises steeply for additional properties and for permanent residents and foreigners.
The Formula
Percentage of an Amount
Amount is the base value, Percentage is the rate applied to it
Worked Example
At a 20% ABSD rate on a $1,000,000 property, the ABSD is $200,000 — payable on top of the standard BSD. ABSD is a Singapore property cooling measure layered on the standard Buyer's Stamp Duty. The rate depends on the buyer's profile: a Singapore Citizen pays no ABSD on their first residential property but 20% on a second and 30% on a third or more; Permanent Residents pay from the first property; and foreigners pay the highest rate (60%). Entities and trustees face higher rates still.
Key Insight
ABSD is the central lever of Singapore's property cooling policy, and the rate — not the formula — is what matters, because it's driven entirely by buyer profile. The structure is tiered by residency and property count: Singapore Citizens pay 0% on their first residential property, a substantial rate on a second (20% after the latest hikes), and more on a third or subsequent (30%); Permanent Residents pay ABSD even on their first property (5%) and steeply more on further ones; foreigners pay a flat very high rate on any residential purchase (60%); and companies, trusts and housing developers face their own (high) rates. The duty is charged on the higher of the purchase price or market value and is paid within 14 days of the agreement — and crucially it stacks on top of the Buyer's Stamp Duty (BSD), the baseline duty every buyer pays on a progressive scale, which this calculator deliberately excludes so you can isolate the ABSD. Important reliefs and rules this tool doesn't model: married couples with at least one Singapore Citizen can claim an ABSD remission when buying a second home if they sell their first within a set period; certain nationalities receive Citizen-equivalent treatment under free-trade agreements; and the 'count' of properties includes those held partially or overseas in some assessments. Because ABSD can dwarf the BSD — 20% of a million-dollar flat is $200,000 — it heavily shapes second-property and foreign-buyer decisions, decoupling strategies, and timing of sales. This calculator shows the ABSD at the rate you choose and the price net of it; for your full upfront duty, add the BSD, confirm the exact ABSD rate for your profile and property count, and check whether any remission applies.
Frequently Asked Questions
How is ABSD calculated?
Multiply the higher of the property's price or market value by your ABSD rate. At 20% on a $1,000,000 property, the ABSD is $200,000. This is on top of the standard Buyer's Stamp Duty (BSD) every buyer pays, which this calculator doesn't include.
What is ABSD?
Additional Buyer's Stamp Duty — a Singapore property cooling measure charged in addition to the Buyer's Stamp Duty. The rate depends on the buyer's profile (Citizen, Permanent Resident, foreigner, or entity) and how many residential properties they already own, rising steeply for additional properties.
What are the ABSD rates?
They depend on profile. A Singapore Citizen pays 0% on a first home, 20% on a second, and 30% on a third or more; Permanent Residents pay from the first property; foreigners pay a flat 60% on any residential purchase; entities and trustees pay higher rates. Rates have been raised several times as cooling measures.
Is ABSD on top of the normal stamp duty?
Yes — ABSD stacks on top of the Buyer's Stamp Duty (BSD) that every buyer pays on a progressive scale. This calculator isolates the ABSD only, so to get your total upfront duty you need to add the BSD as well. Both are payable shortly after signing the purchase agreement.
Can ABSD be remitted or refunded?
In some cases. Married couples with at least one Singapore Citizen can claim a remission on a second home if they sell their first within the qualifying period. Certain nationalities get Citizen-equivalent treatment under free-trade agreements. Check the current rules, as remission conditions are specific and time-limited.

Methodology & Review
The ABSD is the applicable rate (set by buyer profile and number of properties) applied to the property price or value, whichever is higher; the remainder is the price after the duty. It models ABSD only and does not add the separate Buyer's Stamp Duty (BSD) payable by all buyers, nor any remission for qualifying cases.
