Stamp duty calculator FAQ

Quick answers for BSD, ABSD, co-buyers, FTA remission and timing.

What is the difference between BSD and ABSD?

BSD applies to most property purchases and is calculated using residential tiered rates. ABSD is additional stamp duty that depends on buyer profile, number of properties owned, residency status and entity type.

How does ABSD work for joint buyers?

For joint buyers, the highest applicable ABSD profile generally applies to the whole property. That is why a partner or co-buyer profile can change the estimate sharply.

Do some foreigners get Singapore Citizen ABSD treatment?

Yes. IRAS lists FTA remission scenarios where eligible buyers, including US nationals and nationals or permanent residents of Iceland, Liechtenstein, Norway and Switzerland, can receive Singapore Citizen ABSD treatment. Always confirm eligibility against IRAS guidance.

Is stamp duty based on purchase price or market value?

IRAS generally computes BSD and ABSD on the higher of the purchase price and market value. If those are different, use the higher number for a more conservative estimate.

When is stamp duty usually due?

For documents signed in Singapore, stamp duty is generally due within 14 days after signing. If documents are signed overseas, timing can differ, so confirm the exact deadline with IRAS or your lawyer.

Does this calculator include Seller's Stamp Duty?

No. This calculator focuses on buyer-side BSD and ABSD. Seller's Stamp Duty is a separate issue for disposal of residential property within the applicable holding period.

How to use this estimate

Use the result as a decision aid, then verify the numbers that can change your cashflow, tax bill or approval.

Use real market inputs

A calculator is only as good as the rent, price, rate, loan and buyer profile you put into it. Start from a project page or district page when possible.

Treat this as an estimate

These results are for comparison and planning. Confirm taxes with IRAS, loan terms with your bank, and legal dates with your lawyer.

Stress-test the decision

Try a higher interest rate, lower rent, longer vacancy, bigger cash buffer or different holding period before treating the number as comfortable.
