For filing of Thai personal income tax returns with the Thai Revenue Department, these are the cases where foreign-based income is not subject to Thai taxes.

  1. If foreign-sourced income derived before 1st January 2024 and remitted into Thailand in a later tax year
  2. Foreign-sourced income is derived by a foreigner who is NOT a Thailand tax resident but later remitted such income into Thailand

A foreigner is considered a tax resident of Thailand if he/she has stayed in Thailand for at least 180 days during the calendar year and has derived income either within Thailand or outside Thailand.

Moreover, foreigners must include both income sourced within and outside Thailand in the filing of his/her Thai personal income tax return. Taxable income shall be an aggregate amount of Thai-sourced income earned during the tax year and foreign-sourced income remitted to Thailand during the tax year. Hence, if foreign-sourced income is remitted partially, the taxable amount shall be apportioned accordingly.
