Personal taxes

摘要

The top marginal personal income tax rate remains at 35%, while the number of brackets continues to stand at eight. Personal income tax is still waived for the lowest bracket of Bt150,000 of taxable income, with the ceiling raised to Bt190,000 for persons older than age 65. Some executives, investors and experts may be eligible for a maximum personal income tax rate of 17% under the Economic Corridor Act of 2018 or the Investment Promotion Act of 1977 (see National incentives). Tax enforcement is strict, with penalties levied on overdue taxes and underpayments. Personal income tax returns have to be filed by the end of March following the taxable year. The Thailand Revenue Department gives married couples the option to file jointly or separately for income tax assessment.
