Stamp duty in Singapore has two components: Buyer's Stamp Duty (BSD), paid by every purchaser on a tiered scale up to 6%, and Additional Buyer's Stamp Duty (ABSD), an extra levy that depends on your residency status and how many properties you already own. Both must be paid within 14 days of signing the Option to Purchase or Sale & Purchase Agreement (as of 2026-06).
Stamp duty is often the largest upfront cost after the down payment itself. A Singapore Citizen buying a S$1.5 million condominium for the first time will owe roughly S$44,600 in BSD alone — and a second-property purchase at the same price adds a further S$300,000 in ABSD. Knowing the exact figures before you sign an Option to Purchase lets you stress-test your cash flow, avoid nasty surprises at completion, and decide whether strategies such as decoupling are worth exploring. Use the ShiokNest Stamp Duty Calculator to run your specific numbers in under a minute.
What is Buyer's Stamp Duty (BSD)?
BSD is a tax on every property purchase in Singapore, levied on the higher of the transacted price or the market value. It applies to residential, commercial, and industrial properties alike. The rates are tiered — lower bands attract lower percentages — so the effective rate is always blended. For residential property the current bands are (as of 2026-06, per IRAS BSD guidance):
- First S$180,000 at 1%
- Next S$180,000 at 2%
- Next S$640,000 at 3%
- Amounts from S$1,000,001 to S$1,500,000 at 4%
- Amounts from S$1,500,001 to S$3,000,000 at 5%
- Amounts above S$3,000,000 at 6%
The top two residential tiers (5% and 6%) were introduced in February 2023 as part of the government's property market cooling measures. Non-residential BSD rates differ — they top out at 5% — so always verify the property type before computing.
What is Additional Buyer's Stamp Duty (ABSD)?
ABSD is a separate levy stacked on top of BSD. Its purpose is to moderate investment demand and prioritise Singaporean owner-occupiers. The rate depends on two factors: the buyer's residency status and the number of residential properties the buyer (or any co-purchaser) already owns. ABSD applies only to residential property; commercial and industrial purchases are exempt. The current ABSD schedule is (as of 2026-06, per IRAS ABSD guidance):
| Buyer profile | 1st property | 2nd property | 3rd+ property |
|---|---|---|---|
| Singapore Citizen (SC) | 0% | 20% | 30% |
| Singapore Permanent Resident (SPR) | 5% | 30% | 35% |
| Foreigner (non-SC, non-SPR) | 60% | 60% | 60% |
| Entity (company, trust) | 65% | 65% | 65% |
When a property is purchased by co-buyers with different profiles, ABSD is charged on each buyer's share at their respective rate, then summed — unless they qualify for a remission scheme. Married couples where one is SC and one is SPR buying their first home together may apply for a remission to pay at the SC rate. Married SC couples who already own one property can buy a second and claim a refund of the ABSD component paid, provided they sell the first within six months of the second property's completion (or six months of the purchase date for completed properties). This window, and the paperwork, is strict — missing the deadline means the refund is forfeited.
- BSD is progressive (1-6%) and applies to all buyers; ABSD (0-60%) depends on residency and property count.
- Foreigners pay 60% ABSD on top of BSD — stamp duty can exceed $600k on a $1M property.
- Stamp duty must be paid within 14 days of signing the Sales & Purchase Agreement.
- Married couples may qualify for ABSD remission on their first joint property purchase.
You have found the perfect condo at $1.5M. You budget for the down payment, legal fees, maybe even renovation. But have you accounted for stamp duty? For a Singapore Citizen buying their first property, BSD alone adds $44,600 to the bill. For a foreigner? The total stamp duty is a staggering $944,600. The difference between these numbers could make or break your budget.
Stamp duty is the largest hidden cost in Singapore property transactions, and it varies enormously based on your residency status and how many properties you already own. This calculator makes it crystal clear.
What This Calculator Does
Stamp duty can add tens or even hundreds of thousands to your purchase price. Instantly calculate your Buyer's Stamp Duty (BSD) and Additional Buyer's Stamp Duty (ABSD) based on your property price, residency status, and number of properties owned. Updated for 2025 Singapore rates.
You can find this calculator in the Calculators tab on ShiokNest. It updates results instantly as you adjust inputs — no waiting, no page reloads.
Why This Matters
Stamp duty is the single largest transaction cost in Singapore property. For many buyer profiles, it dwarfs legal fees, valuation fees, and agent commissions combined. Getting the stamp duty calculation wrong can leave you short on cash at completion. This matters because:
- ABSD rates range from 0% (SC first property) to 65% (entities) — the same property costs vastly different amounts depending on who buys it
- Stamp duty must be paid in cash — it cannot come from your loan
- ABSD alone on a $1.5M property ranges from $0 to $975K depending on buyer profile
What You Will Discover
After running this calculator with your personal numbers, you will know:
- Your exact BSD amount using the current progressive rate bands
- Your ABSD amount based on your specific buyer profile
- Total stamp duty payable — the number to add to your budget
- How your stamp duty compares across different buyer profiles

Worked Example
Meet three buyers all looking at the same $1,500,000 condo. Watch how stamp duty changes dramatically based on buyer profile:
| Buyer Profile | BSD | ABSD | Total Stamp Duty |
|---|---|---|---|
| SC — 1st property | $44,600 | $0 | $44,600 |
| SC — 2nd property | $44,600 | $300,000 | $344,600 |
| PR — 1st property | $44,600 | $75,000 | $119,600 |
| Foreigner | $44,600 | $900,000 | $944,600 |
The shocking difference: A Singapore Citizen buying their first home pays just $44,600 in stamp duty. But a foreigner buying the same unit pays $944,600 — that is an extra $900,000 in ABSD alone. This is why buyer profile selection in the calculator is so critical.
BSD breakdown: BSD is calculated on a progressive scale: 1% on the first $180K, 2% on the next $180K, 3% on the next $640K, 4% on the next $500K, 5% on the next $1.5M, and 6% on the remainder. The calculator handles all of this automatically.

| Foreigner investor | Price: $2.0M, Profile: Foreigner | The staggering 60% ABSD that makes foreign investment very expensive |
Expert Tips and Common Pitfalls
💡 Pro Tips
- Use realistic assumptions — Singapore condo appreciation has historically averaged 2-4% per year. Avoid overly optimistic projections. When in doubt, use 3% as a baseline.
- Married couple strategy — If both spouses are SC with no existing property, buying under one name keeps the other spouse's "SC 1st property" status for a future purchase.
- Check for ABSD remissions — Married couples buying a joint property may qualify for ABSD remission if they sell their existing property within 6 months.
- Budget stamp duty separately — Stamp duty must be paid in cash (not from loan). Set it aside early.
⚠️ Common Pitfalls
- Forgetting stamp duty is cash-only — You cannot use your loan to pay stamp duty. This catches many first-time buyers off guard.
- Not checking PR upgrade timing — If you are about to receive PR status, waiting could save you thousands in ABSD compared to buying as a foreigner.

Common Mistakes to Avoid
Always check your ABSD rate based on residency status and property count. PRs pay 5% on first property; foreigners pay 60%. Enter your correct buyer profile in the calculator.
Stamp duty is calculated on the purchase price or market value, whichever is higher. For new launches, use the purchase price. For resale, ensure the valuation supports the agreed price.
Stamp duty is due within 14 days of signing. Budget for it as part of your upfront cash requirement, not as a later expense. Use the Total Acquisition Cost calculator to see the full picture.
Worked example: SC couple buying a S$1.5 million condo as their second property
Assume a Singapore Citizen couple (both SC) who already own one HDB flat are buying a S$1,500,000 private condominium. Both are named on the title. The property count of the buyer with the highest count is used, so this is treated as a second property purchase.
Step 1 — BSD on S$1,500,000:
- 1% x S$180,000 = S$1,800
- 2% x S$180,000 = S$3,600
- 3% x S$640,000 = S$19,200
- 4% x S$500,000 = S$20,000
- Total BSD = S$44,600
Step 2 — ABSD on S$1,500,000 at 20% (SC, second property):
- 20% x S$1,500,000 = S$300,000
Total stamp duty payable = S$344,600, due within 14 days of the OTP date. If the couple later sells the HDB within six months of obtaining the keys (assuming an off-plan purchase), they may apply for a full refund of the S$300,000 ABSD. If the flat is sold first before purchasing the condo, the ABSD rate drops to 0% — but they lose the HDB while searching for a replacement and risk bridging gaps. Compare the total cost scenario for your situation using the Total Cost of Ownership calculator.
Decoupling consideration: One way some couples reduce ABSD exposure is decoupling — having one spouse buy out the other's share of the first property so the second purchase falls under a first-property count for the remaining buyer. This strategy involves its own transaction costs (BSD on the share transfer, legal fees, potential MSR/TDSR implications) and is not suitable for HDB flats. The net saving only makes sense above a certain price threshold. Check the broader picture with the Affordability calculator before committing.

Step by step
- Confirm the property type. Residential, commercial, and industrial properties each have different BSD rate schedules. This guide covers residential. If you are buying a shophouse or office unit, use the non-residential BSD table instead.
- Determine the valuation basis. Stamp duty is levied on the higher of purchase price or market value. For a resale purchase, obtain an independent valuation before exercising the OTP if you suspect the price differs from market value. For new launches, the developer's price is typically the higher figure.
- Count the buyer's existing residential properties. ABSD is based on the highest property count among all co-purchasers. Include overseas residential properties — ABSD does not exempt foreign-held assets. If in doubt, consult the IRAS ABSD FAQ.
- Identify the buyer's residency status. Each co-buyer's status matters. If buyers have mixed statuses (for example, SC and foreigner), ABSD is computed per-share unless a remission applies.
- Calculate BSD using the tiered bands. Apply each band rate to the corresponding slice of the purchase price, then sum the results. The ShiokNest Stamp Duty Calculator does this automatically.
- Calculate ABSD. Multiply the full purchase price by the applicable ABSD rate and add the result to your BSD figure.
- Check for remissions or exemptions. Married SC couples, married SC-SPR couples buying their first home together, and qualifying industrial property buyers may be eligible. Apply through IRAS within the prescribed period — remissions are not automatic.
- Verify the payment deadline. Both BSD and ABSD must be paid within 14 days of the date the OTP is exercised or the date of the Sale & Purchase Agreement, whichever is earlier. Late payment attracts penalties. Arrange for cashier's order or online payment through the IRAS e-Stamping portal in advance.
- Factor stamp duty into your overall cash requirement. Stamp duty cannot generally be paid from CPF for investment properties. For owner-occupied purchases, only BSD may qualify under certain conditions. Treat the full ABSD amount as a cash outlay when stress-testing your budget with the Affordability calculator.
- Re-run the numbers if the price is renegotiated. Any price change between OTP and completion that affects the stamp duty basis requires a revised computation. Confirm with your solicitor before completion.
