Buyer's Stamp Duty (BSD) Calculator

Every buyer of Singapore residential property pays Buyer's Stamp Duty, and because the rates are tiered, the total is rarely a round number. This calculator applies the latest 2026 IRAS schedule — 1% on the first $180,000 of the price, rising in steps to 6% on any amount above $3,000,000 — and shows you exactly how much duty falls into each band.

Enter the higher of your purchase price and the property's market valuation and you will instantly see the total BSD payable plus a line-by-line breakdown. Use it to budget your upfront costs before you commit, to sanity-check the figure your lawyer quotes, or to compare two properties side by side. Remember that BSD is only one part of the upfront cost: Additional Buyer's Stamp Duty may also apply depending on your residency and property count.

Frequently asked questions

How is Buyer's Stamp Duty calculated in Singapore?

BSD on residential property is tiered: 1% on the first $180,000, 2% on the next $180,000, 3% on the next $640,000, 4% on the next $500,000, 5% on the next $1,500,000, and 6% on any amount above $3,000,000. The rate is applied to whichever is higher between the purchase price and the property's market value.

Is BSD the same as ABSD?

No. Buyer's Stamp Duty (BSD) applies to every property purchase regardless of who is buying. Additional Buyer's Stamp Duty (ABSD) is a separate, additional tax based on the buyer's residency status and how many residential properties they already own. Many buyers pay both.

Do I pay BSD on the purchase price or the valuation?

IRAS assesses BSD on the higher of the purchase price and the market value. If you negotiate a price below valuation, stamp duty is still charged on the valuation, so enter the higher figure into the calculator for an accurate estimate.

When is Buyer's Stamp Duty due?

BSD is payable within 14 days of signing the Sale and Purchase Agreement (or the date of the document if signed overseas, within 30 days). In practice your conveyancing lawyer arranges payment to IRAS as part of completion.

Can I use CPF to pay Buyer's Stamp Duty?

BSD must generally be paid in cash up front, but you may be able to reimburse yourself from your CPF Ordinary Account afterwards, subject to CPF usage rules for the property. Check with your lawyer and the CPF Board before relying on this.
