BSD and ABSD Estimator
Estimate Buyer’s Stamp Duty and selected Additional Buyer’s Stamp Duty scenarios using source-dated residential-property assumptions.
How to use this BSD / ABSD estimator
Enter the higher of purchase price or market value, then choose the buyer profile and ownership count. Use the result as an upfront-cost estimate when comparing projects or deciding whether ABSD affects the purchase. It excludes remissions, refunds, trust/entity nuances, transitional rules and legal advice.
Rate reference: BSD assumptions are as at 15 Feb 2023 and ABSD assumptions are as at 27 Apr 2023; both rate tables were re-checked against IRAS on 25 Aug 2026. Rules, exceptions and rates can change; verify against live IRAS guidance before making a decision.
Illustrative only. Use the higher of purchase price or market value where applicable, and verify taxes, financing and eligibility with IRAS, your lender, lawyer and relevant professionals.
