Questions about this tool
How many days make me a Thai tax resident?
180 days or more in Thailand within one calendar year, January to December.
Do arrival and departure days count?
Practice varies. This counter counts both arrival and departure days, which is the cautious approach. Ask a Thai tax adviser if you are close to 180.
Does my visa change my tax residency?
No, except the LTR, which has category-specific exemptions. Tax residency depends on days present, not visa type.
Am I taxed on all my foreign income?
Residents can be taxed on foreign income brought into Thailand that was earned from 1 January 2024 onward. Treaties may change the result. Get advice from a Thai tax adviser.
