A resident will be taxable on income from all sources in Thailand on a cash basis regardless of where the money is paid, and on the portion of income that is brought into Thailand in the same year that it is earned.

A non-resident is only taxable on income from sources in Thailand. Taxable income covers both cash and benefits in kind and includes income from employment, hire of work, receipts from copyright, interest, dividends, capital gains and the letting of property.

Tax rates

The tax rates in 2015 for employment income and hire of work are as follows:

Taxable income (Baht) Tax rate %
