Frequently asked questions

How much is stamp duty on a mortgage in Singapore?

IRAS charges 0.4% of the loan granted, capped at S$500, rounded down to the dollar. Any loan of S$125,000 or more pays S$500.

Who pays the mortgage stamp duty?

The mortgagor, which is you as the borrower. IRAS lists mortgage duty under the mortgagor for property mortgages.

When must mortgage duty be paid?

Within 14 days after signing the mortgage in Singapore, or within 30 days after receiving it in Singapore if it was signed overseas. Inside these windows, there is no penalty.

Do HDB loans pay mortgage stamp duty?

Yes. HDB charges 0.40% of the loan granted, up to S$500, and says the solicitor acting for the buyer or mortgagor collects it.

Do I pay mortgage duty again when I refinance?

Yes, if you refinance to a new bank. IRAS says a transfer of mortgage from Bank A to Bank B for refinancing pays 0.4% of the loan, capped at S$500.

What if I take an additional loan on the same property?

Under an existing open mortgage, you pay only the difference between S$500 and the duty already paid. Under a fixed mortgage, the further mortgage is a fresh security and pays full duty again, up to S$500.

What is the penalty for paying mortgage duty late?

Up to 3 months late, the greater of S$10 or the duty. More than 3 months late, the greater of S$25 or 4 times the duty. For S$500 of duty, that is S$500 or S$2,000 on top.

Is mortgage duty the same as buyer's stamp duty?

No. Buyer's stamp duty is on the property price and can run to tens of thousands of dollars. Mortgage duty is on the loan and stops at S$500.
