Stamp duty calculator for private homes
Use this calculator for a private home: a condominium, an apartment or a landed house. Pick the buyer profile and how many homes are already owned, and it gives the residential BSD plus whatever ABSD applies. Swap the opening figure for your own price.
Illustrative figure, enter your own price.
Both duties fall due 14 days after the contract is signed. Free trade agreements put some buyers on citizen ABSD rates: US citizens and US permanent residents, along with citizens of Iceland, Liechtenstein, Norway or Switzerland. They should choose a citizen option. Couples with a Singaporean spouse can sometimes claim ABSD back under IRAS rules. Rates as at October 2026; check with IRAS before you sign.
How the duty is built
Buyer's stamp duty is charged in bands, from 1% on the first slice of the price up to 6% on the part above three million dollars, so the overall rate sits well below the top band. ABSD works differently: one flat percentage on the full price, fixed by citizenship or residency and by how many homes you hold. IRAS wants both settled within a fortnight of signing.

The buyer's stamp duty guide sets out the bands, the ABSD table and the refund rules. The seller's stamp duty guide covers the duty on a later sale. For an executive condominium, use the EC stamp duty calculator; for a shop, office or factory, use the industrial and commercial stamp duty calculator.
