What Is ABSD? Additional Buyer's Stamp Duty Explained

Additional Buyer's Stamp Duty (ABSD) is one of the most-tested — and most misunderstood — topics in the RES exam's tax section. Here's the plain-English version.

What ABSD is

ABSD is a stamp duty charged on top ofthe standard Buyer's Stamp Duty (BSD) when someone buys residential property in Singapore. It's a government cooling measure designed to moderate demand, and the rate depends on the buyer's residency/profile and how many residential properties they already own.

BSD vs ABSD — the key difference

• BSD applies to (almost) every property purchase, tiered by price, for residential and non-residential alike.
• ABSD applies only to residential property and varies by buyer profile (Singapore Citizen, PR, foreigner, entity) and the count of properties owned.

Who pays more

Broadly, a Singapore Citizen buying their first home pays no ABSD, while PRs, foreigners, entities, and anyone buying a second or subsequent property pay progressively higher ABSD. Rates are revised by the government from time to time as a policy lever, so always confirm the current ABSD rates with IRAS before relying on a figure.

Why it matters for the RES exam

Expect questions that give a buyer scenario (e.g. "a PR buying their first condo") and ask which duties apply. The trick is to identify the buyer profile and property count correctly — then apply the right rule. Don't just memorise a rate table; understand the logic.

Practise ABSD, BSD and SSD scenario questions in the taxes & stamp duty topic, and see the exam format guide for how these appear in Section B.
