Property Stamp Duty Audits

IRAS reviews stamping accuracy using a risk-based approach; audit selection does not necessarily mean a mistake has occurred.

Source checked · 11 October 2026

Records and cooperation

IRAS can request signed instruments, valuation evidence and trust-beneficial-owner records. Field officers carry authority cards. Provide access and timely, complete, accurate answers. Unstamped or underpaid instruments can attract penalties up to four times the deficiency; deliberate false statements or omissions can also create criminal consequences.

Assessment and dispute deadlines

A revised assessment states additional duty, penalty and charges. Object in writing with evidence within 30 days of the notice, while paying by the stated due date. A dissatisfied taxpayer may appeal the written decision to the High Court within 30 days and serve the appeal on IRAS within that period. Check third-party stamp certificates and maintain reliable internal stamping controls.
