Avoid a Surprise Seller’s Stamp Duty Bill in Singapore After July 2026
Seller’s stamp duty applies if you bought your residential property on or after 20 February 2010, or an industrial property on or after 12 January 2013, and you’re selling within the holding period. Since 4 July 2025, following the MAS and MOF announcement, the residential holding period is extended, and duty is charged on whichever is higher: your selling price or the property’s market value.
TL;DR:
- SSD rates for residential properties purchased after July 4, 2025, are now higher, with a four-percentage-point increase across all tiers, and the holding period extended to four years.
- The applicable SSD depends on whether the sale occurs within the new four-year holding period, with rates applied to the higher of the sale price or market value, not just the sale price.
- Industrial property has its own schedule, with no SSD owed after holding property for more than three years, regardless of the purchase date, and the old rates still apply.
- Classifying a property correctly relies on zoning, not its use, making IRAS enquiries crucial to avoid unexpected SSD charges for industrial or mixed-use units.
- For sales after July 4, 2025, the exercise date of the Option to Purchase determines whether the new or old schedule applies, impacting the SSD rate significantly.

Who has to pay seller’s stamp duty in Singapore?
Whether seller’s stamp duty (SSD) touches your sale depends on two things: what the property is classified as, and when you bought it. For residential property, IRAS applies SSD-for-residential-property) to purchases made on or after 20 February 2010. For industrial property, the trigger date is 12 January 2013, under a separate industrial SSD schedule.
Zoning under the Master Plan decides the classification, not what the unit looks like or how it’s currently used. A few practical points to check before you assume you’re clear:
- HDB flats are affected too, but you can’t sell before fulfilling the Minimum Occupation Period (MOP), so SSD rarely bites here unless you’re disposing of an investment property acquired separately.
- Commercial property (shops, offices) generally sits outside SSD entirely.
- Land zoned for industrial use, even if partly used for storage or light commercial activity, usually falls under industrial SSD rules.
- Properties acquired before the relevant threshold date are outside SSD scope regardless of how soon you sell.
Current SSD rates and how long you need to hold a property
The rates below reflect the schedule that took effect on 4 July 2025, which now applies to any residential property purchased on or after that date. If you bought earlier, an older schedule may still govern your sale, so the purchase date matters as much as the sale date.
Properties bought before 4 July 2025 remain subject to the previous three-year holding period and lower rate bands, so anyone who exchanged an Option to Purchase (OTP) before that date should check which table their sale actually falls under rather than assume the new one applies.
Industrial property runs on its own, older schedule, unaffected by the July 2025 change:
| Holding period | SSD rate (industrial, purchased on/after 12 Jan 2013) |
|---|---|
| Up to 1 year | 12% |
| More than 1 year, up to 2 years | 12% |
| More than 2 years, up to 3 years | 5% |
Industrial sellers holding past the three-year mark owe nothing under SSD, though other duties may still apply to the transaction.
How is seller’s stamp duty actually calculated?
SSD isn’t simply a percentage of your sale price. IRAS applies the rate to whichever figure is higher: the actual selling price or the property’s market value at the point of disposal. This stops sellers from underdeclaring a sale price to shrink the duty owed.
The calculation follows a consistent process:
- Determine the higher of selling price or market value (a professional valuation settles any dispute here).
- Apply the SSD rate that matches your holding period and purchase date.
- Round the resulting figure down to the nearest dollar.
- Check the minimum duty payable applies if your calculated amount falls below it.
Partial interests complicate things further. If you inherited a share of a property, or co-own it with someone who bought their portion at a different time, SSD is worked out separately for each portion based on its own acquisition date. A flat bought jointly by siblings at different points, for instance, could carry two different SSD rates on the same sale.
Which sales are exempt from seller’s stamp duty?
Not every disposal within the holding period triggers SSD. IRAS carves out several scenarios where duty doesn’t apply, and a smaller set where it applies but can be remitted on application.
Exemptions that generally apply without a separate application include:
- Sales to or acquisitions by the Government or a statutory board.
- Compulsory acquisition of the property by the state.
- Disposal by a court-appointed party in bankruptcy or company insolvency proceedings.
- Transfers under a will or the rules of intestacy.
Remissions are different. Some situations, such as certain transfers within a family arrangement or specific restructuring cases, require you to apply directly to the Commissioner of Stamp Duties rather than assume the exemption applies automatically.
Pro Tip: Don’t assume a transfer “within the family” is automatically exempt. Gifting a property to a relative or transferring it into a trust structure can still attract SSD if the holding period hasn’t lapsed, so get written confirmation from IRAS or your conveyancing lawyer before you sign anything.
What the July 2025 changes mean for your sale
On 3 July 2025, MAS and MOF jointly announced two changes to SSD: the holding period for residential property extended from three years to four, and the rate for every tier rose by four percentage points. The changes took effect the next day, with no transition window.
That last point catches sellers out. If your OTP was exercised on or after 4 July 2025, the new schedule applies to you even if you’d agreed terms, or even signed the OTP itself, before that date. The trigger is the exercise date, not when negotiations started.
The policy intent, according to MOF’s own framing, is to discourage short-term flipping rather than raise revenue, particularly targeting sub-sales of uncompleted units, explained in detail in Why Singapore has no capital gains tax.
In practical terms:
- A property bought in June 2025 and sold ten months later would still fall under the older three-year, lower-rate schedule.
- The same purchase made in August 2025 and sold ten months later would face the new 16% first-year rate, four points higher than before.
- A seller sitting just past the old three-year exemption point now faces one more year of exposure before SSD drops to zero.
Avoiding classification mistakes on industrial and mixed-use property
Misjudging whether a property counts as industrial is one of the most common ways sellers get an unwelcome SSD bill. The Master Plan zoning code, not how the space is currently used, decides the outcome. Categories like B1 (light industrial) and B2 (general industrial) are treated as industrial for SSD purposes, while zoning such as Business Park (BP) can sit in a greyer area depending on the specific use permitted.
A few situations worth flagging before you list a property:
- A unit zoned B1 but rented out as a showroom or office is still industrial for SSD purposes.
- Strata-titled industrial units sold within a business park development often get mistaken for commercial stock.
- IRAS’s own definition of industrial property is the reference point, not the marketing description used when the unit was first sold.
- When in doubt, a written enquiry to IRAS before you accept an offer avoids a costly surprise at completion.
A worked example and checklist before you instruct a lawyer
Say you bought a condo unit for $1,200,000 in September 2025 and receive an offer of $1,350,000 in July 2026, roughly ten months later. A recent valuation puts market value at $1,340,000, so IRAS applies the rate to the higher figure: $1,350,000.
Before instructing a conveyancing lawyer, confirm:
- Your exact OTP exercise date, not just the date you moved in or completed the purchase.
- Whether the holding period has crossed a rate-tier boundary since your purchase.
- A current valuation, ideally from a licensed valuer, to compare against your intended asking price.
- Any history of partial acquisition if you co-own or inherited part of the property.
- Whether your lawyer has the Seller’s Stamp Duty declaration form ready ahead of completion.
Paying SSD: forms, portals and what happens if you get it wrong
SSD is paid through myTax Portal under the Stamp Duty login, and in practice, your conveyancing lawyer usually handles this as part of the completion process rather than leaving it to you.
For residential sales, the law firm acting for you must complete a mandatory Seller’s Stamp Duty declaration form, and these records are typically retained for five years in case IRAS raises a query later.
Getting this wrong carries real consequences:
- Late payment attracts penalties on top of the duty owed.
- Incorrect declarations can trigger an IRAS audit of the transaction.
- Underpaying because of a mistaken exemption claim can leave the seller, not just the lawyer, liable for the shortfall.
What sellers should prioritise right now
If you’re weighing a sale, verify your exact OTP exercise date first. That single detail decides which rate table applies and whether waiting a few more months saves you tens of thousands of dollars. Get an independent market valuation early, since IRAS calculates duty on whichever figure is higher, and a low asking price won’t help you if the market value comes in above it. An experienced agent who understands the current schedule will flag these numbers before you commit, not after you’ve signed.

How Registertoday helps you get the SSD numbers right before you sell
Registertoday is the practical alternative to guessing your SSD exposure from an online calculator with no context for your specific holding period or property classification. Because SSD is charged on whichever is higher between your selling price and market value, an accurate valuation matters as much as the tax table itself, and that’s where a proper home valuation makes the real difference to your bottom line.
Registertoday’s team works through the purchase date, holding period, and classification questions with you directly, then supports the negotiation so the final price reflects what the market will genuinely bear, not a figure that triggers an unexpected higher SSD tier. You can browse comparable sold properties to sanity-check any valuation you’re given, or check current listings via property search before deciding on timing. If you’re planning a sale in the next year, start with a free home valuation and get the SSD conversation settled before you list.
