How many days can you spend in Thailand?
For tax, 180 days or more in Thailand in a calendar year make you resident — so 179 is the most you can spend and stay non-resident. The days don’t have to be in a row, and the count starts again on 1 January.

Tax residency in Thailand: 180 days in the year

Thailand: questions and answers.
How many days can I stay in Thailand without paying tax?
Days decide whether you’re resident, not whether you pay: fewer than 180 in the calendar year keep you non-resident in Thailand.
Does a visa run reset my days in Thailand?
Not for tax: leaving and coming back resets nothing — days in Thailand add up over the calendar year until 1 January.
Does Thailand count days across two calendar years?
No. The 180 days are counted in each calendar year, and the count starts again on 1 January.
