If you are buying a private condo, an HDB resale flat or a shophouse in Singapore, thebuyer stamp duty singapore system will hit your wallet before the keys reach your hand. Buyer Stamp Duty, usually shortened to BSD, is a tax paid on the document that transfers the property to you. On a 1.2 million dollar condo, the bill is 32,600 dollars. On top of that, some buyers also pay Additional Buyer Stamp Duty (ABSD), which can run into six figures. This guide breaks down the 2026 BSD rates, shows you the exact formula, and explains when the tax must be paid so you do not get slapped with a penalty.
What Is Buyer Stamp Duty in Singapore?
Stamp duty is a document tax, not a property tax. It is triggered the moment a document such as an Option to Purchase, a Sale and Purchase Agreement or a transfer instrument is signed. You pay it once, at the point of purchase, and it is not refunded if you later sell at a loss.
Two things determine the amount: the dutiable value and the property type. IRAS uses whichever is higher between the price you agreed to pay and the market value of the property. That rule exists to stop buyers declaring a fake low price to shrink the tax bill.
BSD applies to almost every property acquisition, including HDB resale flats, executive condominiums after their minimum occupation period, private condos, landed homes, commercial units and industrial space. Even a transfer into a trust attracts BSD, because the document still moves an interest.
BSD Rates for 2026: Residential vs Non-Residential
The rate structure has been tiered since 20 February 2018, and the current top marginal rates took effect on 15 February 2023. For residential property the top rate is 6 percent. For non-residential property it is 5 percent. The first few tiers are identical, which means most buyer stamp duty Singapore calculations below 1.5 million dollars come out at the same percentage either way.
| Portion of price or market value | Residential BSD rate | Non-residential BSD rate |
|---|---|---|
| First $180,000 | 1% | 1% |
| Next $180,000 | 2% | 2% |
| Next $640,000 | 3% | 3% |
| Next $500,000 | 4% | 4% |
| Next $1,500,000 | 5% | 5% |
| Remaining amount above $3,000,000 | 6% | 5% |
The tax is rounded down to the nearest dollar, subject to a minimum duty of 1 dollar. That minimum exists so that even a nominal transfer of a 1 dollar property still carries a recorded stamp.
How to Calculate BSD: Step by Step
Any buyer stamp duty Singapore calculation works the same way. It is not a flat percentage of the whole price. You apply each rate only to the slice of value that falls inside that band, then add the slices together. Here is the method:
- Confirm the dutiable value - take the higher of the purchase price and the market value.
- Slice the value into bands - 180,000, then 180,000, then 640,000, then 500,000, then 1,500,000.
- Multiply each slice by its band rate.
- Add everything up and round down to the nearest dollar.
Example 1: HDB resale flat at $600,000
First 180,000 at 1 percent gives 1,800. The next 180,000 at 2 percent gives 3,600. The remaining 240,000 falls in the 3 percent band and gives 7,200. Total BSD payable is 12,600 dollars. That is an effective rate of 2.1 percent.
Example 2: Private condo at $1,200,000
First 180,000 at 1 percent is 1,800. Next 180,000 at 2 percent is 3,600. The next 640,000 at 3 percent is 19,200. That brings the running total to 1,000,000 dollars of value. The final 200,000 sits in the 4 percent band and adds 8,000. Total BSD is 32,600 dollars, an effective rate of about 2.72 percent.
Example 3: Private condo at $2,000,000
Add one more tier. The first 1,000,000 dollars of value produces 24,600 dollars of duty. The next 500,000 at 4 percent adds 20,000, and the last 500,000 at 5 percent adds 25,000. Total BSD is 69,600 dollars. A commercial shophouse at the same price would also pay 69,600, because the 6 percent tier only starts above 3 million dollars.
BSD vs ABSD: The Other Taxes Buyers Pay
BSD is only the entry fee. Depending on your residency status and how many homes you already own, ABSD is charged on top, using the same dutiable value. These rates apply for acquisitions on or after 27 April 2023 and remain unchanged in 2026.
| Buyer profile | ABSD rate |
|---|---|
| Singapore Citizen, first residential property | 0% |
| Singapore Citizen, second residential property | 20% |
| Singapore Citizen, third and subsequent | 30% |
| Singapore Permanent Resident, first property | 5% |
| Singapore Permanent Resident, second property | 30% |
| Singapore Permanent Resident, third and subsequent | 35% |
| Foreigner, any residential property | 60% |
| Entity or trustee, any residential property | 65% |
The gap between profiles is brutal. A foreign buyer purchasing a 1.2 million dollar condo pays 32,600 in BSD plus 720,000 in ABSD, for a total of 752,600 dollars in tax alone. A first-time Singapore Citizen buying the same unit pays only the 32,600. That single difference explains why so many expatriates buy through a Singapore Citizen spouse, or choose non-residential assets that escape ABSD entirely.
Two reliefs are worth knowing. Citizens of the United States, Switzerland, Liechtenstein, Norway and Iceland can be treated as Singapore Citizens for ABSD on their first residential property under the relevant Free Trade Agreements. Separately, a married Singapore Citizen couple may qualify for ABSD remission on a replacement home if they sell the previous one within the allowed window. Both routes have strict conditions, so check the official rules before committing to an Option to Purchase.

When and How to Pay BSD
Timing matters more than most buyers expect. IRAS requires the document to be stamped before you sign it. If you have already signed, the duty must be paid within 14 days after signing for documents signed in Singapore, or within 30 days after the document is received in Singapore for documents signed overseas. Late payments attract penalties that grow with the delay.
Almost everyone stamps online through the myTax Portal using the e-Stamping service. You fill in the property details, pay by internet banking or GIRO, and receive a stamp certificate immediately. Keep that certificate: your lawyer and the other side of the transaction will ask for it, and IRAS can verify its authenticity through its own portal.
Practical points that catch people out:
- The 14 day clock runs from the date the document is first signed, not from completion or the date you collect keys.
- If you grant an Option to Purchase and the buyer exercises it, the exercised option is the document that gets stamped.
- For a joint purchase, duty is computed on the full price, not on your share. Tenancy-in-common splits do not split the bill.
- Budget BSD as cash. It is payable before the CPF withdrawal for the purchase is processed.
Cash flow planning is the usual stumbling block. If you are still building the down payment, our comparison of cash management accounts in Singapore shows where short-term funds can sit while earning a yield, and the HDB grants guide covers the subsidies that can offset part of the price. The Singapore bank account comparison helps you see which banks move fastest on loan servicing.
FAQ: Buyer Stamp Duty in Singapore
Is buyer stamp duty payable on HDB resale flats?
Yes. BSD applies to HDB resale flats and to executive condominiums bought from the open market. New flats bought directly from HDB also attract BSD on the purchase price, computed using the same tiered rates.
Is buyer stamp duty Singapore the same as ABSD?
No. Both are stamp duties but they are separate taxes. BSD applies to nearly every property purchase and is tiered from 1 to 6 percent. ABSD applies only to residential property and depends on your residency status and the number of homes you already own.
Who is responsible for paying buyer stamp duty Singapore?
The buyer, in almost every case. The stamp certificate is issued in the buyer's name and the duty must be paid before the transfer can be registered. Some sale contracts allocate the cost differently between parties, but the legal liability sits with the person acquiring the property.
Can BSD be paid using CPF?
No. Stamp duty must be paid in cash. CPF Ordinary Account savings can be used for the purchase price, the down payment and the legal fees, but the stamp duty itself is not a CPF-eligible expense.
What happens if I pay BSD late?
IRAS imposes a penalty for late stamping. The penalty increases with the length of the delay, and in serious cases IRAS can pursue the unpaid duty plus penalties through the courts. Stamp within 14 days of signing if the document was signed in Singapore.
Is BSD based on purchase price or valuation?
Whichever is higher. If you negotiate a price below market value, IRAS will still compute the duty on the market value. This prevents under-declaration and is why a below-market deal does not reduce your tax.
Do foreigners pay buyer stamp duty as well as ABSD?
Yes. Both apply. A foreign buyer pays BSD at the normal tiered residential rates and then ABSD at 60 percent of the purchase price or market value for any residential property.
Is stamp duty refundable if the sale falls through?
Generally no. Once a document is stamped, the duty stands. There are narrow remission routes for specific situations, such as a rescinded contract ordered by a court or an aborted en bloc sale, but a change of mind is not one of them.
Key Takeaways
- BSD is charged on the higher of the purchase price or market value, using tiered rates from 1 percent to 6 percent for residential property.
- The top residential rate of 6 percent applies only to the portion above 3 million dollars. Most HDB and mass-market condo buyers pay an effective 2 to 3 percent.
- ABSD is separate and stacks on top, ranging from 0 percent for a Citizen's first home to 65 percent for entities and trustees.
- The document must be stamped within 14 days of signing in Singapore, or 30 days of receipt if signed overseas.
- Budget the duty as cash. CPF cannot be used for stamp duty even when it is used for the rest of the purchase.
Conclusion
The buyer stamp duty Singapore bill is one of the few costs in a property purchase that is fully predictable before you sign anything. Work out the band by band figure, add ABSD if it applies to your profile, and set that money aside in cash. Doing the maths before you negotiate puts you in a stronger position, because you will know exactly what each extra 100,000 dollars of offer really costs.
