Stamp Duty Calculator

Stamp duty is a tax payable on documents relating to the purchase, acquisition, sale or disposal of property in Singapore. For property buyers and sellers, the main stamp duties are Buyer's Stamp Duty, Additional Buyer's Stamp Duty and Seller's Stamp Duty.

The AsianPrime Stamp Duty Calculator estimates the stamp duty that may apply to a Singapore property transaction. Depending on the property type, buyer profile, number of properties owned and relevant transaction dates, it can help estimate Buyer's Stamp Duty, Additional Buyer's Stamp Duty and Seller's Stamp Duty.

Buyer's Stamp Duty, or BSD, is payable when you buy or acquire property located in Singapore. IRAS states that BSD is tax paid on documents signed when property in Singapore is bought or acquired.

Yes. Buyer's Stamp Duty generally applies to every purchase or acquisition of property in Singapore, whether residential or non-residential. It is computed based on the purchase price or market value of the property, whichever is higher.

Additional Buyer's Stamp Duty, or ABSD, is an additional stamp duty payable by certain buyers of residential property in Singapore. It is paid on top of Buyer's Stamp Duty and depends on the buyer profile, residency status and number of residential properties owned.

ABSD may apply to Singapore Permanent Residents, foreigners, entities and Singapore Citizens buying their second or subsequent residential property. Singapore Citizens buying their first residential property generally do not pay ABSD, but the position may differ for joint purchases, trust arrangements, entities and other special cases. Buyers should verify the applicable treatment before committing to a purchase.

ABSD is calculated on the purchase price stated in the dutiable document or the market value of the property, whichever is higher. IRAS states that ABSD and BSD are computed on the higher of the purchase price or market value.

Seller's Stamp Duty, or SSD, is a stamp duty that may be payable when a residential property is sold or disposed of within the applicable holding period. It is designed to discourage short-term property flipping and is calculated based on the disposal value and holding period.

Seller's Stamp Duty may apply when a residential property is sold within the applicable SSD holding period. IRAS announced changes for residential properties purchased on or after 4 July 2025, including an increase in the holding period from 3 years to 4 years and higher SSD rates for each holding-period tier.

For residential properties purchased on or after 4 July 2025, the SSD holding period was extended from 3 years to 4 years, and the SSD rates were increased by 4 percentage points for each tier. These changes apply to residential properties purchased on and after 4 July 2025, with no transition period.

Generally, no Seller's Stamp Duty is payable once the property has been held beyond the applicable SSD holding period. However, the correct treatment depends on the property type, acquisition date and disposal circumstances.

BSD is payable by buyers on most property purchases in Singapore. ABSD is an additional duty that may apply to residential property buyers depending on buyer profile and property count. SSD is payable by sellers in certain cases when a residential property is sold within the applicable holding period.

Yes. The calculator may be used to estimate stamp duty for different property types, including residential and non-residential transactions, subject to the inputs selected and the applicable rules for that transaction.

Stamp duty is generally computed on the purchase price or market value, whichever is higher. This means a buyer or seller should not assume that duty is always based only on the stated transaction price.

Stamp duty must generally be paid within the prescribed statutory timeline after the relevant document is signed. The exact deadline depends on the type of document, where it is signed and the nature of the transaction. Buyers and sellers should check the applicable deadline early, because late stamping may result in penalties.

No. The calculator provides an indicative estimate only. The final stamp duty payable may depend on the exact legal document, buyer profile, residency status, property count, ownership structure, acquisition date, disposal date, market value, available remission and IRAS assessment.

ABSD remission may be available in selected situations, such as certain married-couple replacement home scenarios, subject to IRAS conditions. Buyers should not assume remission applies automatically. They should check the eligibility conditions before exercising an Option to Purchase or signing the Sale and Purchase Agreement.

Stamp duty can be a significant upfront cost. Calculating BSD and ABSD early helps buyers understand the full cash and CPF requirement before exercising an Option to Purchase or signing the Sale and Purchase Agreement.

Sellers should check SSD before granting an Option to Purchase because an early sale may trigger a substantial duty. The applicable SSD depends on the acquisition date, disposal date, holding period and relevant SSD rate structure.

After using the calculator, review the estimated BSD, ABSD and SSD against your purchase or sale timeline, buyer profile, property count, ownership structure and available funds. For a binding position, confirm the final duty treatment with IRAS, your conveyancing lawyer or a qualified adviser before committing to the transaction.
