Foreign-Sourced Income

Foreign income is taxed for DTV visa holders who have stayed in Thailand for more than 180 days in a calendar year qualifying them as tax residents.

If this is you, you are taxed on assessable foreign income that you bring into the country. Assessable income encompasses a broad range, including income from employment, freelance work, capital gains, rental income and intellectual property.

For more information, see our article on the tax implications of the DTV visa or book a call with our team to discuss your personal circumstances.

Yes, you can work remotely for a foreign company on a DTV visa without paying Thai taxes if you stay less than 180 days in a calendar year. Non-residents only pay tax on Thai-sourced income. Remote work for a foreign employer is not Thai-sourced. However, if you stay 180 days or more, you become a tax resident and any foreign income brought into Thailand is taxable and you must file a return.

For more information on the DTV and tax, see our article here. If you would like to talk it through, book a call with our team.

As a DTV visa holder staying in Thailand for over 180 days (i.e., all year), you are considered a Thai tax resident. You must pay personal income tax on Thai-sourced income and foreign income brought into Thailand, such as UK earnings.

The UK-Thailand DTA does not exempt you from Thai tax but prevents double taxation. You can claim a tax credit in Thailand for taxes paid in the UK on the same income, reducing your Thai tax liability.

Watch this video to find out more about how the UK-Thailand DTA works. DTAs can be complex to manage, so please don’t hesitate to contact our team if you’d like to discuss further.

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.

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.

For more information on cryptocurrency taxation in Thailand, please visit this link. Thailand has announced a five-year exemption on cryptocurrency gains; however, as of July 2025, this has not been confirmed. Under the proposal, the exemption will only apply to gains on licensed Thai exchanges.
