Taxes on the Thailand DTV

Verified data Last verified June 10, 2026 Reviewed by Henry van de Vorming

Tax is the part of a move people underestimate most. Here's how Thailand treats a DTV holder's income — when you become a tax resident, what happens to foreign earnings, and the official basis for each. It's information, not tax advice.

How it works

The DTV confers no tax privilege. Per the Thai Revenue Department (rd.go.th/english/6045.html), spending more than 180 days in Thailand in a tax (calendar) year makes you tax resident. Residents are taxed on Thai-source income plus any foreign-source income brought into Thailand (the remittance basis); non-residents are taxed on Thai-source income only. Since 1 January 2024, foreign income remitted to Thailand is taxable in the year of remittance regardless of when it was earned (Departmental Instruction Por. 161/2566, corroborated by HLB Thailand). A draft royal decree that would exempt foreign income remitted in the year it is earned or the following year remains unenacted as of June 2026 — it has not appeared in the Royal Gazette, per HLB Thailand, Nishimura & Asahi and Forvis Mazars — so the current remittance rules apply in full. Whether income earned while physically working in Thailand for a foreign employer counts as Thai-source rather than foreign-source is a contested technical point, and double-tax treaties may change the outcome. Consult a Thai tax adviser before acting on any of this.

When you become a tax resident

The usual trigger is time: spend more than 180 days in Thailand in the relevant period and you're generally treated as a tax resident. But a day-count is rarely the whole story — having a permanent home available to you, or your family and centre of life in Thailand, can make you resident sooner. Once resident, the treatment above applies to your income.

If you stay tax-resident somewhere else too, a double-taxation treaty between Thailand and that country usually decides which one taxes a given slice of income — another reason to get personal advice before you move money or change residency.

Thailand tax & the DTV: FAQ

Thailand tax & the DTV: FAQ

When do I become a tax resident in Thailand?

As a rule of thumb, spending more than 180 days in Thailand in the relevant period makes you a tax resident — though residency can also be triggered earlier by having a permanent home or your centre of life there. The exact test is in the notes above.

Is my foreign income taxed in Thailand?

Once you become a Thailand tax resident, Thailand taxes your worldwide income at its standard rates.

Does the DTV come with a tax break?

Not a special one — you're taxed under Thailand's ordinary rules once resident. A double-tax treaty between Thailand and your home country may still affect where specific income is taxed.
