Thailand Tax
Calculator for foreigners

Not exactly tax-free. Thailand taxes a resident's foreign-source income when it is brought into the country, in the year it arrives; foreign income left abroad is not taxed that year. A 180-day resident who brings in 30% of their foreign income pays Thai PIT on that 30%. Pay for work done while you are physically in Thailand is different: it can be taxed wherever it is paid, as the next answer explains.

It can be. Section 41 of the Revenue Code taxes income from work performed in Thailand whether it is paid inside or outside the country, and the Revenue Department's 2024 guide for foreigners gives work performed in Thailand as its example. The DTV carries no tax exemption, and no published Revenue Department ruling deals with remote work for foreign employers or clients. The figures on this page count only the foreign income you bring in, so treat them as the lower bound and confirm your position with a Thai tax adviser.

Before 2024, foreign income was assessable only if it was remitted in the tax year it was earned, so income remitted a year later escaped Thai tax. Revenue Department guidance issued in September 2023 (Por. 161/2566, effective 1 Jan 2024) makes it assessable in the year it is remitted, whichever year it was earned, and income earned before 2024 stays exempt (Por. 162/2566). The calculator uses the current rule.

The Destination Thailand Visa (DTV) is a five-year, multi-entry visa for remote workers that allows stays of up to 180 days per entry, each extendable once by up to 180 days. Holding the DTV does not automatically make you a Thai tax resident — that status is triggered by spending 180+ days in Thailand in a calendar year. Once tax-resident, the remittance rules apply.

7%. The Revenue Code rate is 10%, but Royal Decree No. 807 keeps the rate charged at 7% until 30 September 2027. To add VAT, multiply the price before VAT by 1.07: THB 5,000 becomes THB 5,350. To find the VAT in a price that already includes it, multiply it by 7 and divide by 107: a THB 5,350 bill includes THB 350 of VAT.

Visitors can, on goods bought at shops showing the "VAT Refund for Tourists" sign. You must not be Thai or live in Thailand, and you must fly out of an international airport with the goods within 60 days. Buy at least THB 2,000 from one shop in a day and ask for the P.P.10 form there; purchases of THB 20,000 or more are shown to Customs before check-in. Fees come off the refund, and refunds over THB 30,000 are not paid in cash. The Revenue Department refuses anyone who lives in Thailand or stays more than 180 days, so a long-stay resident should not count on it.

It is a planning-grade estimate, not a certified tax computation. Home-country tax uses broad progressive brackets and social-contribution averages by country and income type — not a full filing model. Thai tax uses the 2026 PIT brackets with a THB 60,000 personal allowance. Use it to understand the order of magnitude, then verify the specifics with a qualified adviser.

Remitted income is the portion of your foreign earnings you transfer to Thailand. The calculator takes it from the city and budget you pick: earning €120,000 on the Standard budget in Bangkok (THB 95,000 a month), you would bring in 25% of your income. The estimate taxes that 25% under Thai PIT. Chiang Mai on the same budget brings in 15%.

It depends on your home country's exit rules. Spain, Germany, and France have specific de-registration requirements and exit tax provisions. Some countries tax residents on worldwide income until formal tax deregistration. This calculator estimates only the Thai side — your home liability must be assessed separately, and CERØ can help you navigate the exit.

Yes. The CERØ service covers DTV visa application, Thai tax residency setup, home-country deregistration guidance, and ongoing compliance. The calculator gives you the numbers; the team handles the paperwork.
