Foreign-Sourced Income

You pay Thai tax on foreign income only when the money enters Thailand and the income relates to a year in which you were a Thai tax resident. Income earned in a non-resident year or before 1 January 2024 is exempt when remitted.

Thailand does not tax foreign income on an arising basis. The tax applies only when both conditions align: the income must relate to a tax-resident year and the money must enter Thailand.

No Thai tax arises under the current remittance rules while the foreign income remains overseas. If the income relates to a year in which you were Thai tax resident and it is later brought into Thailand, it can enter the Thai tax calculation in the year of remittance. Income derived before 1 January 2024 and income from a non-resident year are treated differently.

Yes. Thailand taxes only the foreign income that you remit or spend in Thailand. For example, if you earn $50,000 abroad but remit only $25,000, then Thai tax is calculated only on the $25,000.

Yes, crypto and investment income can be taxed for DTV visa holders if they are tax residents.  Residents pay tax on Thai-sourced income and foreign income brought into Thailand, which includes capital gains or dividends derived from cryptocurrency. Mining income is also taxable.

Yes, digital nomads can utilise Double Taxation Agreements (DTAs) to minimise their tax liability in Thailand. Thailand has DTAs with over 60 countries.

DTAs prevent double taxation. If you are a tax resident, you can claim credits for taxes paid abroad on the same income. This lowers your Thai tax bill. For example, the US-Thailand DTA allows US expats to offset US taxes against Thai taxes. This can mean that you have no tax to pay in Thailand, but you still have an obligation to file.

We have lots of resources on Double Tax Agreements or, if you prefer, book a call with our team to discuss.
