Buyer’s Stamp Duty (BSD) is the base stamp duty Singapore buyers must pay on any property purchase, and it is calculated on the higher of the purchase price or market value using tiered marginal rates. Every buyer owes it, regardless of nationality or how many properties they already hold. You have 14 days from signing to stamp and pay, or 30 days if the document was executed overseas, and Additional Buyer’s Stamp Duty (ABSD), when it applies, comes on top.
TL;DR:
- Buyers should prepare for BSD costs up to S$179,600 for high-value properties exceeding S$3 million, with rates increasing progressively by price bands.
- The BSD calculation must be based on the higher of the purchase price or market value, rounded down to the nearest dollar, with a minimum duty of S$1.
- Stamp duty must be paid within 14 days of signing the contract for Singapore-based deals, or 30 days if executed overseas, to avoid penalties and audit risks.
- ABSD and SSD are separate taxes layered on top of BSD, with ABSD depending on buyer nationality, ownership history, and property count.
- Early valuation checks and timely legal coordination can prevent costly mistakes and ensure compliance with stamping deadlines.

How much is Buyer’s Stamp Duty in Singapore?
For residential property, the current BSD structure) applies marginal rates across six price bands, with the top rate reserved for the portion of the price or value above S$3 million. The Ministry of Finance raised the top marginal rates for higher-value properties effective February 15, 2023, to make the duty more progressive.
Here is the residential schedule as it stands:
| Portion of price or value | BSD rate |
|---|---|
| First S$180,000 | 1% |
| Next S$180,000 | 2% |
| Next S$640,000 | 3% |
| Next S$500,000 | 4% |
| Next S$1,500,000 | 5% |
| Remaining amount above S$3,000,000 | 6% |
Non-residential property, which covers commercial and industrial purchases, uses a shorter schedule with a lower top rate. This is one of the clearest practical differences between residential and non-residential BSD exposure, and it matters if you are weighing a shophouse or industrial unit against a condo at a similar price point.
Two technical details catch buyers off guard. First, BSD is rounded down to the nearest dollar, so a calculation that lands on S$45,678.90 is payable as S$45,678. Second, there is a minimum duty of S$1, which only matters for nominal or very low-value transfers but confirms that no purchase is entirely duty-free.
How to calculate your stamp duty with worked examples
BSD is worked out on whichever is higher: the price you agreed to pay, or the property’s market value as assessed by IRAS. If you strike a deal below market value, perhaps buying from a relative or in a distressed sale, IRAS can charge BSD on the higher assessed figure instead of your contract price. This is why a valuation report matters even when you already have a signed price.
The calculation itself is mechanical. You apply each band’s rate only to the portion of the price that falls within that band, add the results, then round down.
- Identify the higher of purchase price or market value.
- Slot that figure into the residential or non-residential schedule.
- Multiply each band’s portion by its own rate.
- Add every band together.
- Round the total down to the nearest dollar.
Example 1: HDB resale flat at S$550,000. The first S$180,000 is taxed at 1% (S$1,800), the next S$180,000 at 2% (S$3,600), and the remaining S$190,000 at 3% (S$5,700). Total BSD: S$11,100.
Example 2: Private condo at S$1,800,000. First S$180,000 at 1% (S$1,800), next S$180,000 at 2% (S$3,600), next S$640,000 at 3% (S$19,200), and the remaining S$800,000 at 4% (S$32,000). Total BSD: S$56,600.
Example 3: Landed home at S$4,000,000. The first four bands (S$180,000, S$180,000, S$640,000, S$500,000) generate S$1,800, S$3,600, S$19,200, and S$20,000 respectively. The next S$1,500,000 at 5% adds S$75,000, and the remaining S$1,000,000 above the S$3 million mark is taxed at 6%, adding S$60,000. Total BSD: S$179,600.
Total BSD: S$21,600.
Statistic callout: On a S$1,800,000 condo purchase, BSD alone comes to S$56,600, before any ABSD that may apply to your buyer profile.
When is stamp duty due, and what happens if you’re late?
BSD must be paid within 14 days of the date of the signed contract, which is usually the date you exercise the Option to Purchase or sign the Sale and Purchase Agreement. For documents executed outside Singapore, you get 30 days from the date the document is received in Singapore, which matters if you are overseas when the deal closes.
A few points trip up buyers consistently:
- The clock starts from the OTP exercise date for private property, not the completion or handover date.
- HDB resale buyers should track the date the resale application is approved and the agreement is signed, since HDB timelines run on their own schedule.
- Late or non-payment can trigger penalties of up to four times the unpaid duty, a scale that makes missed deadlines far costlier than the administrative hassle of stamping on time.
- IRAS conducts audit checks on stamped documents, so underpaying based on a lowball price rather than assessed market value carries real risk.
- If you are signing documents while based overseas, confirm the receipt date in Singapore in writing, since that date, not your signing date, starts the 30-day clock as explained in Buying Australian Property From Singapore – West Legal & Associates.
BSD versus ABSD and SSD: what’s the difference?
BSD is a flat, universal tax on the transaction itself. Every buyer pays it, and the rate depends only on price and property type, never on who you are. Additional Buyer’s Stamp Duty is a separate charge layered on top for certain buyer profiles, and it can dwarf BSD in dollar terms for investors or foreign buyers. Our earlier breakdown of BSD versus ABSD exposure covers how quickly the combined bill can climb for a second or third property.
- ABSD depends on citizenship, permanent residency status, and the number of residential properties you already own, with rates that rise sharply for additional purchases.
- You must complete an ABSD Declaration Form and retain it, since IRAS does not require submission at purchase but does require it for audit purposes for at least five years.
- Seller’s Stamp Duty (SSD) is a different obligation entirely: it falls on the seller if they dispose of a residential property within a set holding period, and it never substitutes for the buyer’s BSD or ABSD liability.
- Our guide to ABSD rates and exemptions walks through the profile-based rate tiers in more depth than this BSD-focused piece allows.
Because BSD and ABSD are assessed separately but due at the same time, your total stamp duty bill on a single purchase can include both, and planning for only one is a common and costly oversight.
Are there exemptions or remissions from Buyer’s Stamp Duty?
BSD remission exists for specific residential land purchases intended for non-residential development, such as land bought for approved commercial or industrial use, though IRAS requires documentation proving the intended use before granting remission.
- Mixed-use properties without clear zoning documentation are often treated as fully residential for BSD purposes by default, which pushes the calculation toward higher rates.
- A professional valuation can support a different allocation between residential and non-residential components, and it is worth commissioning one before you stamp if your property has a mixed-use title.
- CPF funds can be used toward BSD for eligible property purchases, but the usage rules depend on your CPF balances and the specific scheme, so confirm the limits with your conveyancing lawyer before counting on CPF to cover the full amount.
Budgeting checklist: what consultants check before you stamp
Getting the BSD number right is only part of the job. The bigger risk is discovering a valuation gap, a missed ABSD scenario, or a stamping deadline after the fact. A practical budget for any purchase should include BSD, a realistic ABSD estimate for your buyer profile, legal conveyancing fees, a valuation report fee, caveat registration costs, and any CPF offset you plan to apply. Our breakdown of these hidden upfront costs lays out typical fee ranges buyers overlook.
Timing matters as much as the math. Instruct your lawyer as soon as the OTP is exercised, not after, so the 14-day stamping clock never catches you by surprise. Request a valuation early if your purchase price looks lower than comparable transactions, since IRAS may assess BSD on market value instead. If you are signing from overseas, get written confirmation of the document’s receipt date in Singapore, since that date starts your 30-day window, not your signature date.
Pro Tip: Before you stamp, confirm your OTP exercise date, gather any valuation evidence, and complete your ABSD Declaration Form, even if you believe ABSD does not apply to you. Consultants typically check all three before advising a client to proceed.
Buyers planning a second property often underestimate how BSD and ABSD stack. Our guide to budgeting for a second property walks through that combined exposure in more detail.
A practitioner’s view on stamp duty mistakes
The most common error we see is buyers treating BSD as an afterthought, calculated only once the deal is done. The second is assuming a below-market price will simply be accepted by IRAS without question. Both mistakes are avoidable with an early valuation check and a clear read on the stamping deadline the moment an OTP is signed.
Clients who budget BSD, and any ABSD exposure, before they negotiate tend to walk into completion with no surprises. That single habit saves far more stress than any last-minute scramble to meet a 14-day deadline.

FAQ
How can I avoid paying stamp duty?
You cannot avoid Buyer’s Stamp Duty itself since it applies to every property purchase in Singapore. Legitimate remission only exists for narrow cases such as residential land earmarked for approved non-residential development, and these require documentation submitted to IRAS before stamping.
Do foreigners need to pay ABSD?
Foreign buyers generally face Additional Buyer’s Stamp Duty on top of BSD, with the exact rate depending on their residency status and the number of properties they already own. This is separate from BSD, which every buyer pays regardless of nationality.
How do I get a stamp duty certificate from IRAS?
Once you pay your stamp duty through IRAS, a stamp certificate is generated electronically through the e-stamping system as proof of payment. You can retrieve or reprint this certificate through your IRAS myTax Portal account using the document reference number from your original transaction.
Does the seller have to pay stamp duty too?
Sellers do not pay Buyer’s Stamp Duty, since that obligation sits entirely with the buyer. A seller may owe Seller’s Stamp Duty if they sell a residential property within the applicable holding period, but this is a distinct obligation that never replaces or reduces the buyer’s BSD liability.
