Stamp duty calculator: BSD + ABSD
Enter the purchase price (or market value, if higher) and your buyer profile to see Buyer's Stamp Duty and ABSD for a Singapore property.
Worked example
A Singapore Citizen buying a second home at S$1.5 million: BSD = 1% x 180,000 + 2% x 180,000 + 3% x 640,000 + 4% x 500,000 = S$44,600; ABSD at 20% = S$300,000; total S$344,600.
Figures computed with the same formula as the calculator and unit-tested against official examples.
How it works
BSD is tiered. For residential property bought on or after 15 Feb 2023: 1% on the first S$180,000, 2% on the next S$180,000, 3% on the next S$640,000, 4% on the next S$500,000, 5% on the next S$1.5 million and 6% on the rest. Non-residential property tops out at 5%. IRAS's own worked example of a S$4,500,100 home gives S$209,606 of BSD, which this calculator reproduces.
ABSD is a flat rate on the whole price and depends on who is buying and how many homes they already own. From 27 Apr 2023: Singapore Citizens pay 0% on a first home, 20% on a second and 30% on a third or more; PRs pay 5%, 30% and 35%; foreigners 60%; entities 65%. Some couples and buyers can get remission or a refund (for example, married couples with at least one Singapore Citizen who sell their first home within six months) - check IRAS.
Stamp duty is computed on the higher of the price and market value and is usually due within 14 days of signing. IRAS rounds BSD and ABSD down to the nearest dollar (minimum duty S$1); the calculator does the same.
