Seller Stamp Duty Singapore: Rates, Calculation & How to Avoid It
Most investors obsess over the entry costs of Singapore property — ABSD, BSD, legal fees — and underestimate the exit tax. That exit tax is the Seller's Stamp Duty, and for anyone who sells within three years of buying, it can wipe out an entire year's rental income in a single transaction.
What Is Seller's Stamp Duty?
Seller's Stamp Duty (SSD) is a transaction tax imposed by IRAS on the seller of any residential property disposed of within three years of its acquisition. It was introduced specifically to deter short-term speculative flipping, and the rates are steep enough to accomplish that goal.
The holding period is measured from the date of the purchase contract (or the Option to Purchase) to the date of the sale contract — not the legal completion dates.
SSD Rate Table
| Holding Period from Acquisition Date | SSD Rate |
|---|---|
| Up to 12 months (Year 1) | 12% |
| More than 12 months, up to 24 months (Year 2) | 8% |
| More than 24 months, up to 36 months (Year 3) | 4% |
| More than 36 months (after Year 3) | 0% |
SSD is calculated on the higher of the sale price or the market value of the property at the time of sale.
Worked Example: The Cost of Selling in Year 1
An investor purchases a condominium for S$1.5M in January 2026. The market rises, and the investor sells the same unit for S$1.8M in November 2026 — eleven months later, still within Year 1 of the holding period.
SSD calculation:
- Sale price: S$1,800,000
- SSD rate (sold within 12 months): 12%
- SSD payable: S$216,000
The property appreciated by S$300,000. After S$216,000 in SSD, the pre-tax capital gain is only S$84,000 — before legal fees, agent commissions, and any ABSD paid at purchase. In many scenarios, the effective return on capital is negative.

What Counts as the Acquisition Date?
The holding period starts on the date the Option to Purchase (OTP) is exercised, or the date of the Sale and Purchase Agreement — whichever triggers the formal transaction. It is not the date of legal completion or the date keys are handed over.
This matters because new launch condominiums typically have a 3-4 year construction period. An investor who exercises their OTP on a new launch in early 2026 and receives their TOP in 2029 must still hold for 36 months from the 2026 OTP exercise date before they can sell SSD-free. Selling immediately upon receiving the keys — which could feel like a brand new property — may still attract 4% or 8% SSD depending on the exact dates.
When SSD Does Not Apply
- Holding for more than 36 months: The single most reliable way to avoid SSD. Investors with a clear 3+ year horizon can freely plan their exit.
- En bloc (collective sale) proceeds: If your development is sold en bloc by the Collective Sale Committee through a statutory process, SSD is still payable on your share of the proceeds if you are within the three-year window. The en bloc structure does not provide SSD relief.
- Inherited property: When you inherit a property via a will or the Intestacy Law, you inherit the deceased's acquisition date. If the deceased owned it for more than three years, the heirs can sell immediately without SSD.
- Transfers between divorcing spouses: Courts can grant relief from SSD on transfers made pursuant to divorce proceedings.
The Interaction Between SSD and ABSD
The double duty problem is most severe when a buyer pays ABSD to acquire a second property and then needs to sell within three years — whether due to changed circumstances, job relocation, or financial pressure.
An SC who paid 20% ABSD (S$300,000) on a S$1.5M second property and sells in Year 2 faces:
- BSD already paid: S$44,600
- ABSD already paid: S$300,000
- SSD at 8% on S$1.6M sale proceeds: S$128,000
- Total government duties across the full transaction: S$472,600
This is why the standard advisory for Singapore investment property is a minimum five-year holding horizon — long enough to avoid SSD, generate meaningful rental income to recover ABSD, and see two housing market cycles.
How the Stamp Duty Calculator Works
For any residential property, the combined stamp duty cost on entry and exit can be modelled as:
Entry: BSD (progressive) + ABSD (flat, by profile) Exit within 3 years: SSD (flat, by holding period)
The break-even holding period — the point at which cumulative rental income and capital appreciation recover the combined stamp duty outlay — is highly sensitive to the ABSD rate paid. For an SC investor paying 20% ABSD on a S$1.5M purchase, break-even at a 3% net rental yield sits around 12 to 15 years, assuming no SSD (which means holding for 3+ years minimum).
For a detailed calculation that maps your specific buyer profile, holding period, and projected rental yield against the full stamp duty stack, the Singapore Investment Property Guide includes worked worksheets for the most common investor scenarios.
SSD rates are set by IRAS. All figures above are based on current IRAS schedules. Confirm with a licensed conveyancing solicitor before executing any transaction.
