Vi arbetar på en omfattande utbildningsguide för Additional Buyer Stamp Duty (ABSD). Kom tillbaka snart för steg-för-steg-förklaringar, formler, verkliga exempel och experttips.
The Additional Buyer's Stamp Duty (ABSD) calculator helps property buyers in Singapore determine how much additional stamp duty they must pay on top of the standard Buyer's Stamp Duty (BSD). ABSD was introduced in 2011 and has been revised multiple times to cool the residential property market and prioritise housing for Singapore Citizens. ABSD is charged on the purchase price or market value of a residential property, whichever is higher, and the rate depends on the buyer's citizenship status and the number of residential properties they already own. As of 2023, Singapore Citizens pay 0% ABSD on their first property, 20% on their second, and 30% on their third and subsequent properties. Permanent Residents pay 5% on the first property and 30% on the second. Foreigners pay a flat 60% on any residential property purchase. Entities such as companies and trusts pay 65%. These rates represent a significant cost that can amount to hundreds of thousands of dollars on expensive properties. There are limited remissions: married couples with at least one SC partner can claim a remission on their first jointly-owned property if neither has previously owned Singapore property. The decoupling strategy — where one spouse transfers their share to the other before buying a second property — is also used by some buyers to reset property count, though this itself triggers stamp duties and legal costs. Understanding ABSD is critical before making any property purchase decision in Singapore.
ABSD Amount = Property Price × ABSD Rate; Total Stamp Duty = BSD + ABSD; Effective Cost = Purchase Price + BSD + ABSD + Legal Fees
- 1Determine the buyer's citizenship status: Singapore Citizen, PR, Foreigner, or Entity.
- 2Count how many residential properties the buyer currently owns in Singapore.
- 3Apply the relevant ABSD rate from the 2023 rate table to the purchase price or market value (higher of the two).
- 4Calculate BSD separately on the same value using the progressive BSD rate schedule.
- 5Add ABSD and BSD to find the total stamp duty payable.
- 6Check if any remissions apply — for example, married SC/PR couples buying a first joint property under specific conditions.
- 7Factor in ABSD when comparing properties and financing to understand the true total acquisition cost.
No ABSD on first residential property for SCs
Singapore Citizens are fully exempt from ABSD on their first residential purchase. BSD alone applies.
Second property ABSD rate is 20% for SCs since April 2023
ABSD of $400,000 is a very significant cost. A buyer paying $2M for a property effectively pays $2.45M all-in including stamp duties.
60% ABSD applies to all foreign buyers regardless of property count
At 60% ABSD, foreigners pay almost as much in stamp duty as the property itself. This rate was doubled in April 2023 to further discourage speculative foreign demand.
Remission available if at least one SC and property is first for both
Married SC/PR couples can claim ABSD remission on their first residential property purchase. The application must be submitted within 6 months of purchase.

SC/PR married couple remission
{'title': 'SC/PR married couple remission', 'body': 'Married couples where at least one is a SC can claim ABSD remission on their first joint residential property if both have not previously owned residential property. The remission must be applied for and approved by IRAS.'} When encountering this scenario in absd singapore calculations, users should verify that their input values fall within the expected range for the formula to produce meaningful results. Out-of-range inputs can lead to mathematically valid but practically meaningless outputs that do not reflect real-world conditions.
Trustee purchases
{'title': 'Trustee purchases', 'body': 'Properties purchased by trustees on behalf of beneficiaries are assessed ABSD based on the citizenship status and property count of the beneficial owner, not the trustee. Trusts as entities pay 65%.'} This edge case frequently arises in professional applications of absd singapore where boundary conditions or extreme values are involved. Practitioners should document when this situation occurs and consider whether alternative calculation methods or adjustment factors are more appropriate for their specific use case.
Inherited properties
{'title': 'Inherited properties', 'body': 'Properties acquired through inheritance may still count toward the property ownership total for ABSD purposes when the buyer subsequently makes a new purchase.'} In the context of absd singapore, this special case requires careful interpretation because standard assumptions may not hold. Users should cross-reference results with domain expertise and consider consulting additional references or tools to validate the output under these atypical conditions.
Properties held overseas
{'title': 'Properties held overseas', 'body': 'Overseas properties do not count toward the Singapore property count for ABSD purposes. Only residential properties in Singapore are counted.'} When encountering this scenario in absd singapore calculations, users should verify that their input values fall within the expected range for the formula to produce meaningful results. Out-of-range inputs can lead to mathematically valid but practically meaningless outputs that do not reflect real-world conditions.

What is the ABSD rate for foreigners in 2023?
Foreigners pay 60% ABSD on any residential property purchase in Singapore, regardless of how many properties they own. This rate was raised from 30% in April 2023. In practice, this concept is central to absd singapore because it determines the core relationship between the input variables. Understanding this helps users interpret results more accurately and apply them to real-world scenarios in their specific context.
Do PRs pay ABSD on their first property?
Yes. Permanent Residents pay 5% ABSD on their first residential property and 30% on the second. There is no ABSD exemption for PRs on the first property. This is an important consideration when working with absd singapore calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied. For best results, users should consider their specific requirements and validate the output against known benchmarks or professional standards.
What happens if a spouse owns property before marriage?
Each buyer's property count includes properties owned before marriage. If either spouse previously owned a property, the joint purchase may not qualify for the first-property ABSD rate. This is an important consideration when working with absd singapore calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied. For best results, users should consider their specific requirements and validate the output against known benchmarks or professional standards.
Is ABSD payable on HDB flats?
ABSD applies to all residential properties including HDB flats. However, since HDB eligibility restricts buyers from owning private property, ABSD mostly applies to private residential transactions. This is an important consideration when working with absd singapore calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied. For best results, users should consider their specific requirements and validate the output against known benchmarks or professional standards.
Can developers get ABSD remission?
Yes. Licensed housing developers can apply for ABSD remission if they sell all units within 5 years of acquiring the land. Failure to sell within the deadline forfeits the remission. This is an important consideration when working with absd singapore calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied.
When must ABSD be paid?
ABSD must be paid within 14 days of signing the Sales and Purchase Agreement or the Option to Purchase (if exercised). Late payment attracts penalties. This applies across multiple contexts where absd singapore values need to be determined with precision. Common scenarios include professional analysis, academic study, and personal planning where quantitative accuracy is essential. The calculation is most useful when comparing alternatives or validating estimates against established benchmarks.
What is decoupling and does it reduce ABSD?
Decoupling involves one co-owner transferring their share to the other so one spouse has zero properties and can buy a new one without ABSD. However, the transfer itself triggers BSD and possibly ABSD, so the math must be done carefully. In practice, this concept is central to absd singapore because it determines the core relationship between the input variables. Understanding this helps users interpret results more accurately and apply them to real-world scenarios in their specific context.
Are industrial or commercial properties subject to ABSD?
No. ABSD only applies to residential properties. Commercial and industrial properties are subject only to BSD. This is an important consideration when working with absd singapore calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied. For best results, users should consider their specific requirements and validate the output against known benchmarks or professional standards.
Proffstips
Always calculate ABSD upfront before signing any option to purchase. At 20–60% of the property price, ABSD can be the single largest acquisition cost. If you are an SC buying a second property, model whether the rental yield justifies the ABSD outlay before committing.
Visste du?
Singapore has one of the highest property stamp duty rates in Asia. The 60% ABSD for foreigners introduced in April 2023 was designed to send a clear signal that Singapore prioritises housing affordability for its own residents — and it caused a measurable drop in foreigner purchases within months of implementation.
