Thailand tax residency rules

Threshold: 180 days · Day Count · Calendar year (Jan 1 – Dec 31)

Thailand triggers residency at 183 cumulative days in a calendar year. Historically, residents were taxed only on foreign-source income remitted to Thailand the same year earned. Effective 2024, foreign-source income remitted in any year is taxed if you were a resident the year it was earned.

  • 183 days in a calendar year = Thai tax resident.
  • 2024 reform: foreign-source income remitted to Thailand is now taxed regardless of year remitted, if earned during a residency year.
