Quick answer
You stop being a Thai tax resident by spending fewer than 180 days in Thailand in a calendar year. There is no exit tax, no deregistration form and no formal departure procedure for individuals in 2026. You still file a final P.N.D. 90/91 by 31 March for your last resident year, and Thai-sourced income stays taxable afterwards.

Ceasing Thai tax residency in 2026: the key figures
| Item | 2026 rule |
|---|---|
| Residence ends when | You spend fewer than 180 days in Thailand in the calendar year |
| Exit tax | None for individuals |
| Final return | P.N.D. 90 or 91 by 31 March of the following year (about 8 April online) |
| Late filing | THB 2,000 fine, plus 1.5% monthly surcharge on unpaid tax |
| Foreign income remitted as a non-resident | Not taxable |
| Thai-sourced income as a non-resident | Taxable; 15% withholding on most payments, 10% on dividends |

Is this guide for you?
Read on if you…
- are leaving Thailand for good and want a clean break with the Revenue Department;
- plan to keep an apartment in Thailand but stay under 180 days a year;
- have freelance or company income in Thailand and need to wind it down properly.
Probably not your case if you…
- are arriving rather than leaving – see our guide to obtaining Thai tax residency;
- are closing a Thai company, which has its own liquidation and corporate tax clearance rules.
What actually ends your Thai tax residency?
Only one thing: the day count. Section 41 of the Revenue Code makes you resident for any calendar year in which you are present for 180 days or more. Stay 179 days or fewer and you are non-resident for that whole year, from 1 January.
There is no form to file to "leave" the tax system, no exit interview and no deregistration of your tax identification number. The number stays with you for life and can be reused if you come back.
Two consequences surprise people.
- Residency is all-or-nothing per year. If you leave on 15 July 2026 after 196 days, you are resident for all of 2026, including income you remit in November from abroad. Leaving on 20 June, after 171 days, makes you non-resident for the whole year.
- Your visa is irrelevant. Cancelling a work permit or letting a DTV lapse changes nothing for tax. Equally, keeping a long-term visa does not keep you resident if you stay under 180 days.
If you keep ties in Thailand (a home, a Thai spouse), nothing in Thai law overrides the day count. Treaty tie-breakers only matter when two countries both claim you, and if you are under 180 days Thailand does not. Our full guide to Thai residency rules covers the counting details.
Residence tests on the way out
| Test | Does it keep you Thai resident? |
|---|---|
| 180 days or more in the calendar year | Yes – the only test |
| Home or apartment in Thailand | No |
| Thai spouse or children | No |
| Thai company, work permit or visa | No |
| Thai bank accounts or property | No (but income from them stays Thai-sourced) |
What do you still have to file and pay after leaving?
Leaving does not cancel the obligations of your last resident year. Work through these steps.
- File the final annual return. Submit P.N.D. 91 (employment only) or P.N.D. 90 (other income) for your last resident year by 31 March of the following year. You can e-file from abroad through the Revenue Department's e-filing portal if you already have an account.
- File the half-year return if relevant. Freelancers and landlords with income under Sections 40(5)–(8) owe P.N.D. 94 by 30 September for January–June income, even in a departure year.
- Settle withholding certificates. Collect your 50 Tawi withholding certificates from employers and clients. They prove tax already paid and support any refund claim.
- Deregister for VAT if you were registered. A VAT-registered freelancer (turnover above THB 1.8 million) must notify the Revenue Department within 15 days of ceasing business and file a final P.P. 30.
- Cancel your work permit and notify your employer. This is a labour-law step, not a tax one, but employers must report your departure and finalise payroll withholding.
- Consider a tax clearance certificate. Section 4 quater of the Revenue Code still allows the Revenue Department to require a tax clearance certificate (P.3) from departing foreigners with outstanding liabilities or certain Thai business income. In practice it is rarely demanded of employees and freelancers.
- Keep your records. The Revenue Department can assess within 2 years of filing, extended to 5 years for suspected evasion, and up to 10 years where no return was filed.
How are you taxed on Thai income after you become non-resident?
Thailand keeps taxing Thai-sourced income whoever you are. What changes is scope and mechanics.
- Rent from Thai property: taxable at progressive rates, with 15% withholding when paid by a company. You still file P.N.D. 90.
- Dividends from a Thai company: 10% final withholding. A treaty may reduce this.
- Interest and royalties: 15% withholding, often reduced by treaty.
- Sale of Thai property: withholding at the Land Office on the sale, calculated on the appraised value with deemed expenses, plus specific business tax of 3.3% if sold within five years. See our capital gains guide.
- Work physically done in Thailand on short visits: Thai-sourced employment income, taxable, though many treaties exempt it if you stay under 183 days and are paid by a foreign employer with no Thai permanent establishment.
Foreign income is the big win. A non-resident is never taxed on foreign-sourced income, remitted or not. That means money you earned abroad while resident, kept offshore, can be brought into Thailand tax-free in a later year when you are non-resident.
Your exit plan: before, during and after
Before you leave (3–6 months out)
- Count your days for the current year and decide whether to finish it resident or not. If close to 180, a short trip abroad can swing it.
- Delay remitting foreign income until a year you will be non-resident, if that is the plan.
- Sell or restructure Thai assets with the withholding and specific business tax in mind.
- Check the treaty with your next country for any overlap period.
While you leave (last 60 days)
- Collect withholding certificates and bank statements.
- Give notice on VAT registration and work permit if applicable.
- Confirm your e-filing login works from abroad and update your contact address with the Revenue Department.
After you leave (next filing season)
- File the final P.N.D. 90/91 by 31 March and pay or claim a refund.
- Request a certificate of residence (R.O. 22) for the final resident year if your new country wants proof of where you were taxed.
- Keep a day log if you plan to return for visits.
Example – Priya, freelance data consultant from the UK
Priya lived in Chiang Mai from 2023 and decides to move to Lisbon. She leaves on 18 June 2026 after 169 days, so she is non-resident for 2026. Her 2026 client fees of GBP 85,000 (about THB 3.7 million) were paid to a UK account. She remits THB 800,000 in October 2026 to settle her lease and pay a Thai accountant. Because she is non-resident for 2026, that remittance is not taxable. Had she left on 2 July, after 183 days, the THB 800,000 would have been assessable and cost her roughly THB 48,500 in Thai tax. Her only 2026 Thai liability is withholding on a THB 120,000 project done physically in Bangkok in February.
Priya's exit turned on a fortnight and one remittance date. Yours may too.

Check my tax setup →Common mistakes (and what they cost)
- Leaving in July thinking the year is over. 180 days reached means the whole year is resident; foreign income remitted afterwards that year is taxed at up to 35%.
- Skipping the final return because you have gone. Unfiled returns carry a THB 2,000 fine, a 1.5% monthly surcharge, and a 10-year assessment window.
- Leaving a VAT registration open. Nil returns are still due monthly; each missed one triggers a fine.
- Selling property without checking the five-year rule. Specific business tax of 3.3% applies on the full sale price if you sell within five years of acquiring.
- Forgetting the new country's arrival rules. You can become resident in your destination before leaving Thailand, creating dual residency and double filing.
Frequently asked questions
Does Thailand have an exit tax?
No. Thailand has no exit tax or deemed disposal rule for individuals who cease residency. Unrealised gains on shares, crypto or foreign assets are not taxed on departure. What remains taxable is Thai-sourced income after you leave, and foreign income you remitted in a year you were still resident.
Do I need to tell the Revenue Department I am leaving?
There is no formal departure notification for individuals. You simply file the final return for your last resident year. If you were VAT-registered, you must notify the Revenue Department within 15 days of ceasing business. Updating your contact address is sensible so that any refund or query reaches you abroad.
Can I keep my Thai bank account and condo after leaving?
Yes. Owning property or holding accounts does not make you tax resident. Rental income and interest stay Thai-sourced and taxable, with withholding at source: 15% on rent paid by companies, 15% on interest. You still file P.N.D. 90 for rental income even as a non-resident.
What if I come back next year?
Residency is assessed each calendar year on days alone. You can be non-resident in 2026 and resident again in 2027 by crossing 180 days. Your tax identification number stays valid. Plan remittances with that in mind, as foreign income remitted in a resident year is assessable.
Is money I earned while resident taxed if I remit it later?
Under the rules in force since 2024, foreign-sourced income is taxed on remittance only if you are resident in the year of remittance. Income earned while resident, kept abroad and remitted in a non-resident year is not taxable. Keep records showing both the earning year and your day count for the remittance year.
Will Thailand still issue me a residence certificate for my last year?
Yes, for any year in which you were resident and filed a return. Request form R.O. 22 from the Revenue Department after filing. Your new country may ask for it to apply the treaty for the overlap period.
