Hi, I have a tax related question.

If I work in Thailand as a remote worker with a visa for foreign clients, does that count as foreign sourced income? Or is it Thai based income since I myself work in Thailand?

Thank you in advance.

TLDR : Answer Summary
The determination of whether income earned by remote workers in Thailand counts as foreign sourced or Thai based income depends on several factors. If the individual spends 180 days or more in Thailand during a calendar year, they become a Thai tax resident and may have a tax liability on their income, regardless of where it originates. Under Thai domestic law, income earned is typically considered Thai sourced if the work is performed in Thailand. However, if there is a double tax agreement between Thailand and the country where the income is from, the worker may be able to claim a tax credit or exemption.

It is considered Thai sourced income under the domestic laws - taxable whether it is paid here or overseas. But double tax treaty may provides tax exemption or allows you to claim tax credit.

It depends. If you spend 180 days or more inside Thailand in any calendar year then you are a Thai tax resident for that year. If you bring income into Thailand during that year then you have a Thai tax liability for that income. If your income is from a country that has a dual tax agreement with Thailand then you can claim a credit for any tax already paid on that income
