Additional Buyer's Stamp Duty (ABSD) is on top of standard Buyer's Stamp Duty (BSD). Singaporean Citizens: 0% on first property, 20% on second, 30% on third+. PRs: 5% on first, 30% on second. Foreigners: 60% on any residential property (raised from 30% in April 2023). Married couple property count is shared - one spouse owning means second purchase = "second property" rate.
How ABSD works alongside BSD
Every residential purchase in Singapore pays BSD (Buyer's Stamp Duty) on a sliding scale: 1% on first S$180K, 2% next S$180K, 3% next S$640K, 4% next S$500K, 5% next S$1.5M, 6% above S$3M. So a S$1.5M property pays S$44,600 in BSD.
ABSD adds on top, based on buyer profile and how many residential properties you already own.
Worked example: SC couple buying second property at S$1.5M. BSD = S$44,600. ABSD 20% = S$300,000. Total stamp duty: S$344,600 - 23% of purchase price.
Foreigner buying same S$1.5M: BSD S$44,600 + ABSD 60% (S$900,000) = S$944,600. The April 2023 hike effectively shut foreign demand for SG residential.
Married couples: combined property count
Married couples are treated as one unit for ABSD. If either spouse owns property, the next purchase counts as a "2nd property" purchase at the higher ABSD rate. This applies even if only one spouse is on the new title.
Decoupling strategy (largely closed post-2024): Pre-2024, couples sometimes "decoupled" - selling one spouse's interest in their first property to the other so the "free" spouse could buy a new property at first-property rates. New IRAS rules (2024+) treat this as a property transfer subject to BSD/ABSD. Decoupling no longer effective for ABSD avoidance in most cases.
ABSD remission for married SC couples: If both are SCs, you buy a second property, AND you sell your first within 6 months of TOP/key collection - the ABSD on the second is fully refunded. Strict timeline.
Foreigner exceptions
Some Free Trade Agreement (FTA) nationals get treated as PRs for ABSD: USA, Iceland, Liechtenstein, Norway, Switzerland (FTA national tier-1 list). Means Americans pay PR rates (5%/30%/35%) instead of foreigner 60%.
Note: this only applies to natural persons; entities still pay 65%. And the FTA list is small - check IRAS for current.

Use our 🇸🇬 Singapore calculator to plug in your own numbers and see exactly what you owe / save.
April 2023 hike from 30% to 60% was part of property cooling measures. The aim: shut foreign speculative demand. It worked - foreign buying dropped sharply.
Can I avoid ABSD by buying under company?
Entities pay 65% ABSD (60% + 5% additional for entities). Trust structures are also flagged. ABSD avoidance schemes are heavily penalized.
What's the 6-month ABSD remission?
If a married SC couple buys a second residential and sells the first within 6 months of TOP/key collection, the ABSD on the second is fully refunded.
ABSD on commercial property?
No - ABSD applies only to residential. Commercial / industrial / shophouses (mixed-use) have different stamp duty rules.
Can I refund ABSD if I sell quickly?
No - ABSD is non-refundable except for the SC married-couple 6-month sale-of-first-property remission. Selling for any other reason doesn't refund ABSD.
Key takeaways

Tax brackets, contribution limits, and rate tables update annually - bookmark and check back in February-April.
Most planning decisions hinge on marginal tax rate, not effective rate.
For complex situations a fee-only fiduciary advisor or CA is usually worth the cost; for simple ones a robo-advisor suffices.

By audience: what to focus on
Different reader types need different angles on this topic. Pick the one closest to your situation.
Salaried employees
Maximise tax-advantaged retirement contributions (EPF/401(k)/SIPP/RRSP). Check whether your country prefers the old vs new regime, employer-match thresholds, and salary-sacrifice options. Use the calculators below with your CTC / gross income.
Freelancers / self-employed
You bear higher self-employment tax + lose the employer match, but get access to higher contribution limits (Solo 401k, SEP-IRA, NPS Tier-I). Track business expenses meticulously. Quarterly estimated tax payments avoid underpayment penalty.
NRIs / expats
Tax residency rules (183-day, tie-breaker), double-taxation treaties, foreign tax credits all come into play. NRI restrictions on PPF (no new accounts) but expanded options on NPS. Cross-border income often needs specialist advice.
Retirees / pre-retirees
Sequence-of-returns risk in early retirement is the largest threat. Glide-path asset allocation, Roth-conversion analysis in low-income years, Required Minimum Distribution planning, and Medicare/healthcare gap funding (US) are the big items.

What is the most important thing to know about this topic?
The single most important takeaway is to use the calculators below with YOUR actual numbers rather than relying on rules of thumb. Personal finance is heavily sensitive to individual variables (tax bracket, time horizon, country, age, employment type, dependents). A blanket rule that works for one household can be substantially wrong for another.
Where can I find authoritative source data for this?
Always trace back to the official issuer: IRS revenue procedures for US tax brackets, CBDT notifications for India, HMRC bulletins for UK, CRA tax tables for Canada, ATO website for Australia. Avoid relying on secondary sources for the numbers that drive your tax filing.
How often do these numbers change?
Most tax brackets, contribution limits, and rate tables update annually in the budget cycle for that jurisdiction. Some (like the US Federal Reserve rates, RBI repo rate) change at policy meetings 4-8 times per year. Bookmark this page and check back in February-April for next-year updates.
Does this apply to non-resident / NRI / expat scenarios?
Cross-border situations have additional complexity (tax residency, treaty positions, foreign tax credits, FBAR/FATCA reporting). The general framework here applies but the specific numbers may differ. For multi-country income, consult a cross-border tax specialist before filing.
Yes. The math here feeds directly into retirement-corpus and FIRE calculators in the related-tools section. Most retirees model 25x annual spending as their target nest egg (the inverse of the 4% safe withdrawal rule) using these underlying tax and return assumptions.
How accurate are the calculators on this site?
Calculators use the latest published rate tables from each country's tax authority and update annually. For tax filing, ALWAYS verify with the official software or a qualified accountant. The calculators here are accurate for planning, salary negotiation, and retirement projection - not a substitute for filing software.
Are there country-specific versions of this content?
Yes. Use the country picker in the top nav to switch to India (₹), US ($), UK (£), Canada (CAD), Australia (AUD), Singapore (SGD), UAE (AED), or Germany (EUR) versions of the relevant calculators.
What's the difference between effective and marginal tax rate?
Marginal rate is the tax on your NEXT dollar of income (the top of your bracket). Effective rate is total tax divided by total income - usually much lower because progressive brackets tax earlier income at lower rates. Deductions save tax at your marginal rate, not effective. Most planning decisions hinge on marginal rate, not effective.
Is this information current?
Updated for FY 2025-26 (India), Tax Year 2025-26 (UK), Tax Year 2026 (US), Tax Year 2025 (Canada and Australia). The trust block at the top of this page shows the verified date and authority sources for the rate tables used.
Where can I get personalised advice?
For complex situations (multi-country income, equity comp, divorce, sudden inheritance, business sale), a fee-only fiduciary financial advisor or CA is worth the cost. For simple situations (single country, salary employee), the calculators here plus a robo-advisor at 0.25% AUM is usually enough.
