Tax residency in Thailand

How to become a tax resident — and how hard it is to leave.

How to become a tax resident

Typically after 180+ days of presence in a year — or any of:

• Present in Thailand for an aggregate period of 180 days or more in a tax (calendar) year

A self-funded remote or high‑net‑worth individual can move to Thailand mainly via the Long‑Term Resident (LTR) visa for ‘Work‑from‑Thailand professionals’ or wealthy categories, or the five‑year Destination Thailand Visa (DTV) for digital nomads, both obtained through Thai embassies/e‑Visa systems and administered by the Board of Investment and Immigration Bureau.

Tax residency is triggered solely by spending 180+ days in Thailand in a calendar year, so it generally ends by reducing physical presence below this threshold in subsequent years, with no domicile or citizenship-based tail rules.

“A resident of Thailand is any person residing in Thailand for a period or periods aggregating more than 180 days in any tax year.” — The Revenue Department, Kingdom of Thailand
