Understanding stamp duty

What is stamp duty?

Stamp duty is a government charge on certain legal documents and property transactions. For property buyers, it is usually one of the main costs when transferring land or a house.

Who usually pays it?

In a normal property purchase, the buyer usually pays stamp duty and related registration costs. The final responsibility depends on the agreement and legal process.

Why can the final amount change?

The final payable amount can depend on the accepted property value, province, document type, exemptions, and official assessment. Always verify with the relevant authority or notary before payment.

Formula used

Property sale / transfer = 3% on first LKR 100,000 + 4% on balance
Gift of property = 3% on first LKR 50,000 + 2% on balance
Mortgage bond = 0.1% of mortgage value
Lease / rent agreement = 2% of total lease or rent value entered
Total estimated cost = estimated stamp duty + other optional costs entered
