Stamp duty is a tax that is imposed on legal documents and other instruments. Payment of the duty is certified by the attachment of a stamp.
Thailand’s Revenue Code lists the types of instruments that are subject to stamp duty. It applies to 30 different types of legal documents, at rates specified in the schedule attached to the Chapter VI of Title II of the Revenue Code.
The tax is levied on documents or instruments related to land transfers and leases, stock transfers, debentures, letters of credit, mortgages, promissory notes, annuities, life insurance policies, powers of attorney and travelers’ checks. These instruments are subject to duty at a rate of 0.1 per cent, without a specified upper limit. Loan documents are subject to duty at a 0.05 per cent rate, subject to an upper limit of 10,000 baht.
Stamp duty is applied to instruments and not to persons or transactions. Duty stamps must be affixed to a document when it is executed, if the document is executed in Thailand, or by 30 days of the date the document is brought into the country.
