How inheritance tax works in Thailand
Thailand inheritance tax applies only to the amount of a legacy that exceeds THB 100 million received from each testator. The standard rate is 10%, but ascendants and descendants pay 5%, and the spouse is exempt.
The tax can cover immovable property, securities, bank deposits or similar claimable money, registered vehicles and other financial assets prescribed by royal decree. The return is generally due within 150 days of receiving the legacy.
Estate planning in Thailand also has to consider lifetime gifts, because gifts can be taxed as personal income when they exceed the relevant family or custom thresholds.

Watch out for
- The inheritance tax is narrow but real, so large property portfolios, shareholdings and bank balances need an estate plan.
- Lifetime gifts can also be taxed, with separate THB 20 million and THB 10 million exemptions depending on who gives the gift.
- Foreign wills and succession documents still need to be checked against Thai asset holding and probate rules.
