How much Thai income tax will you pay?
Tell us where you live, what you earn and what you send to Thailand. The calculator classifies your income under Thai law, checks the tax treaty with your country and finds every deduction you qualify for. You never need to know the name of a deduction.
- Free and anonymous – no account, nothing stored unless you choose to save
- Deterministic rules from the Revenue Code, versioned per tax year
