Seller's Stamp Duty (SSD) in Singapore: 5 Mistakes to Avoid
Calculates SSD for residential property bought on or after 4 July 2025 and sold within four years. The maths is not complicated, but a handful of errors come up again and again in this and related property & hdb calculations. Here is what to watch for.
Singapore's property market is shaped by cooling measures introduced since 2009, including Additional Buyer's Stamp Duty, loan-to-value limits and debt servicing ratios. These rules are adjusted when the market runs hot, so the numbers you see today may differ from what friends paid a few years ago.
Beyond the price, buyers should budget for legal fees, valuation, home insurance, renovation and furnishing. Running the figures in advance helps you decide how much cash to hold back and whether a smaller loan or longer tenure makes more sense.
1. Forgetting the cash portion
Part of the downpayment must be in cash, and CPF cannot be used for it.
2. Using the advertised interest rate for affordability
Banks apply a stress-test rate to TDSR and MSR calculations.
3. Ignoring SSD when selling early
Selling within four years of buying (for purchases from 4 July 2025) attracts Seller's Stamp Duty.
4. Forgetting ABSD on a second property
Citizens pay 20% ABSD on a second residential property, which can be hundreds of thousands of dollars.
5. Overlooking other costs
Legal fees, valuation, fire insurance, renovation and agent fees all add to the total outlay.
The correct method
16% if sold within one year, 12% in year two, 8% in year three, 4% in year four, and nothing after that.
For example, with these inputs:
- Selling price or market value (S$): 1,500,000
- How long you held the property: Up to 1 year
the calculator returns:
- Seller's Stamp Duty: S$240,000.00
Properties bought before 4 July 2025 follow the older three-year schedule (12%, 8%, 4%).
