Property Mortgage Stamp Duty

Mortgage duty depends on the instrument and secured amount, with a S$500 maximum for the listed categories.

Source checked · 11 October 2026

Rates and calculation

From 22 February 2014, a mortgage is charged at 0.4% of the loan amount, capped at S$500. An equitable mortgage signed under hand is charged at 0.2%, also capped at S$500. Transfers or assignments of a mortgage or debenture use 0.2% of the amount transferred, including arrears interest, subject to the same cap. Round down to a whole dollar, with minimum duty of S$1.

Additional borrowing and refinancing

An additional loan secured under an existing open mortgage can require the difference between S$500 and duty already paid; none is due once that open mortgage has reached the cap. A further fixed mortgage is a fresh security with its own charge. Refinancing through a mortgage from one bank to another can attract 0.4% duty. Under-hand security over property outside Singapore is exempt under the stated rule.
