Quick answer: A Thailand Tax Residence Certificate is an official document used to confirm that a person is a resident of Thailand for tax purposes for a specified tax year. It may be requested by overseas tax authorities, banks, employers, investment platforms, accountants or counterparties when applying an applicable Double Taxation Agreement or documenting international tax residence.

Provide evidence of Thai tax residence when applying provisions of an applicable tax treaty between Thailand and another jurisdiction.

Foreign bank or institution

Support tax-residency checks requested by a bank, broker, investment platform, employer or financial institution.

Withholding tax matters

Support a treaty-based tax position where reduced withholding may apply, subject to the relevant treaty and circumstances.

Foreign tax filing

Provide supporting evidence to an overseas accountant or tax authority when confirming your country of tax residence.

Document Thai tax residence when you have companies, dividends, consulting income or business interests across borders.
