Frequently Asked Questions

IRAS says the party who pays is usually stated in the agreement; where it isn't, IRAS lists the purchaser as the party who pays BSD and ABSD. A seller who sells within the seller's stamp duty (SSD) holding period pays SSD separately.

Within 14 days after signing the document in Singapore, or within 30 days after receiving it in Singapore if it was signed overseas. IRAS imposes a penalty for late payment.

For an HDB flat, or a new EC bought from the developer, ABSD is remitted automatically: in full if any buyer is a Singapore Citizen, down to a flat 5% for Singapore PR buyers. For private property, a married couple that includes a Singapore Citizen and buys a second home in both names can have the ABSD refunded if they sell their first home within 6 months of buying a completed home, or within 6 months of the new home's TOP or CSC (whichever is earlier) if it is still under construction. Under free trade agreements, nationals of the USA, and nationals and permanent residents of Iceland, Liechtenstein, Norway and Switzerland, get the same stamp duty treatment as Singapore Citizens. Conditions and documentation are strict — confirm with IRAS or your lawyer.

ABSD is assessed at the highest rate among all the buyers. A married SC + Foreigner couple is therefore charged the Foreigner ABSD rate unless they qualify for the marital remission.

Yes, frequently. ABSD rates were last revised in Apr 2023 (foreigner rate doubled from 30% to 60%). Always verify the latest rates on IRAS before transacting.
