Reviewed 16 September 2026. This is general information, not Thai tax or immigration advice. Seek advice from a Thai-licensed professional before remitting substantial foreign income.
A Thailand Destination Thailand Visa can permit a long stay. That does not decide your tax position. If you spend 180 days or more in Thailand during a tax year, you may become a Thai tax resident under section 41 of the Revenue Code.
Immigration permission and tax residence are separate
The DTV is a multiple-entry visa valid for five years. Official consular information describes stays of up to 180 days per entry and refers to an in-country extension. Whether an individual receives an extension depends on the current rules and the responsible immigration office.
Tax residence, by contrast, turns on physical presence during the calendar tax year. A visa does not create an exemption from Thai tax rules.
Foreign income remitted to Thailand
Thailand’s Revenue Department issued Director-General’s Orders Phor.161/2566 and Phor.162/2566 in 2023. They changed the Department’s approach to foreign-sourced income remitted to Thailand by tax residents. The treatment can depend on the income type, timing, source country and any applicable double-tax agreement.
Do not assume that an overseas salary, dividend, pension, rental payment or investment gain stays outside Thai tax simply because it arose overseas. Equally, do not assume every remittance is taxed in the same way. The facts matter.
90-day reporting is different again
Address reporting to Thai Immigration is an immigration obligation; tax residence is a Revenue Department issue. A person can have one obligation, both, or neither depending on their stay and visa status. Keep records of entry and exit dates, address reports, income, remittances and foreign tax paid.
What to do before a long stay
Count your days in Thailand from 1 January to 31 December. Before sending significant foreign funds to a Thai account, ask a Thai tax adviser to review your income type, source country and any double-tax agreement. If you intend to apply for a DTV extension, check the latest process directly with Thai Immigration.
