Two Duties on a Purchase at Thomson Eight
A purchase at Thomson Eight brings two possible stamp duties. The first, Buyer’s Stamp Duty, is levied on each purchase and scaled purely to the price. The second, ABSD, is scaled to the purchaser instead: a Citizen, a permanent resident, a foreign buyer or a company or trust, and the count of residential properties held when the contract is signed.
IRAS expects both within a fortnight of the signing date. The rates below are those set by IRAS as at November 2026.
Under progressive payments the price falls due in stages as the building rises, yet both duties are still computed on the whole price when the contract is signed. The sum is therefore ready from day one, in cash or from CPF, together with the first instalment.
Thomson Eight Buyer’s Stamp Duty in Bands
| Band of the price | Rate |
|---|---|
| First S$180,000 | 1% |
| Following S$180,000 | 2% |
| Following S$640,000 | 3% |
| Following S$500,000 | 4% |
| Following S$1,500,000 | 5% |
| Above S$3,000,000 | 6% |
Work from an illustrative S$2,000,000, picked only to show the arithmetic and having nothing to do with any Thomson Eight price. Its bands total S$69,600: S$1,800, S$3,600, S$19,200, S$20,000 and S$25,000.
ABSD for Each Thomson Eight Buyer Profile
| Who signs | Owns no home yet | Owns one already | Owns two or more |
|---|---|---|---|
| Citizen | 0% | 20% | 30% |
| Permanent resident | 5% | 30% | 35% |
| Foreign buyer | 60% | 60% | 60% |
| Company or trust | 65% | 65% | 65% |
Staying with that illustrative S$2,000,000, ABSD comes to nothing on a Citizen’s first home, S$100,000 on a permanent resident’s first, and S$400,000 on a Citizen’s second. Under trade treaties, Americans, Icelanders, Liechtensteiners, Norwegians and the Swiss, along with American permanent residents, pay ABSD as Citizens would.
Thomson Eight Duty Timing and Remission
Because ABSD looks at what a buyer owns on the day of signing, upgraders who still hold a home at that point pay the higher rate. Spouses buying together, one or both of them Citizens, can claim it back by selling the earlier home inside the IRAS deadline, provided they meet every condition.
Seller’s Stamp Duty is separate. For properties acquired on or after 4 July 2025, it applies to a resale inside four years, at 16% in year one, then 12%, 8% and 4%.
