Singapore Seller Stamp Duty Calculator

Enter the sale price (or market value, whichever is higher), the date you purchased the property, and the date of the sale. The sale date defaults to today, but you can change it to model a future sale. The calculator updates instantly with no submit button to press.

The purchase date is required and drives everything: it determines which rate table applies and, combined with the sale date, how long you held the property. Picking the wrong table for your purchase date is the single most common error in this calculation, so the calculator shows exactly which table it used and why.

If your purchase date is before 11 March 2017, the calculator flags it as out of scope rather than guessing a rate, since that predates both tables it is built on.

Seller Stamp Duty is a flat percentage of the sale price, not a band walk like Buyer Stamp Duty. The rate depends on how long you held the property and which rate table applies to your purchase date.

Table A applies to properties purchased on or after 4 July 2025: 16% if sold within 1 year, 12% within more than 1 up to 2 years, 8% within more than 2 up to 3 years, 4% within more than 3 up to 4 years, and 0% after more than 4 years.

Table B applies to properties purchased between 11 March 2017 and 3 July 2025 inclusive: 12% if sold within 1 year, 8% within more than 1 up to 2 years, 4% within more than 2 up to 3 years, and 0% after more than 3 years.

The holding period is counted in full calendar months between your purchase and sale dates, then converted to years and months. SSD payable is simply the sale price multiplied by the rate for the band your holding period falls into.

The large green figure is the SSD payable, with the applicable rate and band shown just below it. The three cards break out your exact holding period, the rate applied, and which table was used, so you can see at a glance whether you are close to crossing into a lower band.

Because SSD drops to 0% once you clear the final band, timing a sale to cross that threshold can save a meaningful amount, especially on Table A where the top rate is 16%. The "which table applied and why" note explains the reasoning behind the table selection so you can double check it against your own purchase date.

This is an estimate based on the published SSD rate tables. It does not account for any exemptions that may apply to your situation. Confirm the exact figure with IRAS or a qualified conveyancing lawyer before relying on it for a transaction.
