# How many days make you tax resident in Thailand? > How Thailand decides tax residency: 180 days More than 180 days in aggregate in any tax (calendar) year; the periods do not have to be continuous, the tax year (1 January – 31 December), the tests that catch you regardless of days, and The Revenue Department (กรมสรรพากร)'s own page — checked 2026-08-18.

Next step **How we know** Figures are as The Revenue Department (กรมสรรพากร) publishes them at rd.go.th, checked 18 August 2026. Sources are listed further down the page. ## How the counting works The Revenue Department states: "'Resident' means any person residing in Thailand for a period or periods aggregating more than 180 days in any tax (calendar) year" and "A resident of Thailand is liable to pay tax on income from sources in Thailand as well as on the portion of income from foreign sources that is brought into Thailand." Thailand therefore taxes residents on a REMITTANCE basis for foreign income, not on worldwide income — hence worldwideIncome false. THE 2024 CHANGE: Revenue Departmental Instruction Paw. 161/2566 (Sept 2023), as clarified by Paw. 162/2566 (Nov 2023), applies from 1 January 2024 and removed the previous same-calendar-year limitation — foreign-source income earned from 1 January 2024 onwards is assessable whenever it is remitted to Thailand, not only if remitted in the year it was earned. Foreign income earned before 1 January 2024 is not caught when later remitted. The Revenue Department's English PIT page states the remittance rule but does not itself cite Paw. 161/2566, so the instruction numbers and dates come from the secondary sources listed. A draft royal decree/ministerial regulation that would exempt foreign income remitted in the year it is earned or the following year had NOT been published in the Royal Gazette as at this check and is not law; the 2024 rule still governs 2026 remittances. specialRegimes is left null: the Long-Term Resident (LTR) visa tax concessions could not be confirmed on a Revenue Department page during this check. ## Why the day count is the part you can control Ties, homes and intentions are argued after the fact; days are a record. That is why the first thing an adviser asks for is a list of the days you were in the country — and why reconstructing it from boarding passes and photos a year later is a bad afternoon. Log each stay as it happens and the tally is simply there, with the dates that produced it.

Checked 18 August 2026 against rd.go.th. **When is Thailand's tax year?** 1 January – 31 December. Day counts are measured against that year unless the rule names a different period — here, More than 180 days in aggregate in any tax (calendar) year; the periods do not have to be continuous. **Are residents of Thailand taxed on worldwide income?** Not in the usual way: Thailand taxes on a territorial basis, so foreign-source income may fall outside the net.
