Foreign income you bring into the country
A resident is taxed on Thai-source income and on the part of foreign income brought into Thailand; non-residents only on Thai-source income. If you are paid by a foreign employer or clients, the key question is how much of that money you transfer into the country and when: review it with an adviser and your country's treaty.
Prepare your tax consultation
Gather stay dates, previous residence, contract, clients and income by category. Ask about treaty, registration, returns, VAT and contributions for your profile, and deadlines for the relevant year. Special benefits require confirming conditions and application.
Things to keep in mind
These points vary with your situation, your home country or the consulate. They are worth confirming with the official source before you take the next step.
- How foreign income is taxed depending on the year it is earned and transferred.
- Treaty with your country and credit for taxes paid abroad.
