Tax in Thailand for expats and long-stay residents — 2026 overview
Thailand's tax rules for long-stay foreigners changed significantly in 2024, and understanding the current framework is important for anyone earning income while living in Pattaya. This guide provides a plain-language overview of Thai tax residency, the 2024 remittance rule change, the LTR flat rate benefit, and the practical implications for different visa holders. This is not professional tax advice — for your specific situation, consult a qualified Thai tax adviser. We can refer you to English-speaking advisers in Pattaya and Bangkok who work with expats.
Thai tax residency
You are a Thai tax resident if you spend 180 or more days in Thailand in a calendar year. Tax residency is determined purely by physical presence — it has no direct connection to your visa category. A tourist who spends 200 days across multiple visits is technically a Thai tax resident for that calendar year. A DTV holder who spends 150 days in Thailand that year is not. Visa status and tax residency are separate concepts that happen to correlate for long-stay residents.
The 2024 remittance tax change
Before January 2024, Thailand taxed foreign-source income only if it was remitted to Thailand in the same calendar year it was earned. Many expats and long-stay residents planned their finances around this by remitting previous years' savings rather than current-year income, legally avoiding Thai tax on foreign income.
From January 2024, Thailand changed this rule: foreign-sourced income remitted to Thailand is assessable for Thai personal income tax if you are a Thai tax resident in the year you remit it, regardless of the year it was earned. This affects people who remit foreign income to Thai bank accounts while spending 180+ days/year in Thailand. Key points:
- Only income remitted to Thailand is assessable — income that stays in overseas accounts is not
- Savings accumulated before 1 January 2024 are exempt (grandfathered) — only post-2024 earnings are subject to the new rule
- Thailand's personal income tax rates are progressive: 5% (0–150,000 baht), 10% (150,001–300,000), 15% (300,001–500,000), 20% (500,001–750,000), 25% (750,001–1,000,000), 30% (1,000,001–2,000,000), 35% (above 2,000,000)
- Tax treaties (Thailand has treaties with 60+ countries including UK, Germany, USA, Australia) may reduce double taxation — confirm with a tax adviser whether your country's treaty applies
Practical implications for Pattaya expats
Non-O retirement holders: The ฿800,000 bank balance requirement involves keeping money in Thailand — but this is savings evidence, not income remittance. If the ฿800,000 represents savings from a previous year (pre-2024), it is grandfathered. New transfers of current-year pension or investment income to your Thai bank account are potentially assessable if you are a tax resident (180+ days). Many retirees who have stayed under 180 days per calendar year or who remit prior-year savings are unaffected. Those who remit current pension income above the tax-free threshold while spending 180+ days in Thailand should file a Thai tax return.
DTV holders (remote workers): If you are a DTV holder spending 180+ days in Thailand and remitting foreign employment income to your Thai account, that income is potentially assessable from 2024 onwards. The 25–35% progressive rates apply at higher income levels — for earners above ฿1,000,000 remitted per year (approximately $28,000–$30,000), tax planning matters.
LTR Work-from-Thailand: the 17% flat rate advantage
LTR Work-from-Thailand Professional holders who file under the LTR scheme pay a flat 17% personal income tax rate on their qualified income. At income levels above approximately ฿800,000–฿1,000,000 per year, this flat rate is lower than the progressive standard rates, generating meaningful annual savings. For a remote professional earning $80,000/year and remitting all of it to Thailand, the difference between the standard progressive rate (reaching approximately 25–30% at that income level) and the LTR 17% flat rate represents approximately ฿100,000–฿200,000 in annual tax savings. The LTR application effort is justified at this income level for long-term Thailand residents.
Filing a Thai tax return
Thai personal income tax returns (PND 90 or PND 91) are due by March 31 for the preceding calendar year (online filing deadline may extend to April). Non-residents with Thai-source income also have filing obligations. If you are a Thai tax resident who has remitted foreign income to Thailand, you should file — even if deductions and treaty credits result in nil or minimal tax due. Failure to file when required is a technical violation. Thai tax returns can be filed online at the Revenue Department portal (rd.go.th) or through a tax adviser. Most Pattaya expats use a tax adviser for the first filing and may self-file subsequently for simple returns.
