Seller’s Stamp Duty: rates and the 4-year rule.
Seller’s Stamp Duty (SSD) applies when you sell a home soon after buying it. It is charged on the sale price or market value, whichever is higher, whether or not you made a profit.

| Sold within | SSD |
|---|---|
| 1 year | 16% |
| More than 1 to 2 years | 12% |
| More than 2 to 3 years | 8% |

How is the holding period counted?
For most purchases the clock starts on the date you accepted the Option to Purchase, and the sale date is generally when your buyer accepts yours. IRAS’s example: a home bought on 7 July 2025 has no SSD if sold on or after 7 July 2029.
Does SSD apply to HDB flats?
Yes, if an HDB flat is sold within the holding period. For normal sales the 5-year MOP usually runs past the holding period, but check your dates.
Who pays, and when?
The seller pays, within 14 days of the sale contract, through myTax Portal. Late payment attracts a penalty.
How to avoid it
Time the sale. If you are close to the anniversary, the OTP date of your sale decides the rate, so plan marketing so the OTP falls after it. The stamp duty calculator shows BSD, ABSD and SSD together.
