Documentation and Compliance

If people have over 120,000 THB of foreign-sourced income that is remitted to Thailand, then they must file a Thai tax return regardless of whether they have a tax liability or not. For married couples who wish to file jointly, they must file if they have over 220,000 THB.

You must get a tax certificate or document to show that taxes are being paid in another jurisdiction. This can potentially be used to file as a credit against any tax owed in Thailand. You will need to file a Thai tax return, including the information of all funds remitted to Thailand.

Tax is based on the amount remitted in Thai baht at the time of transfer or spending. The applicable exchange rate is taken from the Bank of Thailand on the date of the transaction. Average rates are not used; the exact daily rate applies.
