Asia · how a foreigner who moves to Thailand is taxed · 2026 · Mixed
If you move to Thailand, you become a tax resident when 180+ days in a calendar year. As a resident you are taxed on a remittance basis basis — Residents are taxed on Thai-source income plus foreign-source income earned from 1 Jan 2024 onward that is remitted to Thailand; foreign income kept offshore is not taxed. The top personal income tax rate is 35%. A foreign pension is treated as: Taxable as remitted foreign income if brought into Thailand (earned 2024+); LTR-visa pensioners are exempt on remitted foreign income. Thailand also offers the Long-Term Resident (LTR) visa regime, which can sharply change this picture. It has a US tax treaty and lacks a US totalization agreement.

What this means if you relocate to Thailand
The first thing that matters is tax residency: 180+ days in a calendar year. The 180-day line is the headline trigger, but a home, family or business ties can make you resident sooner — so counting days alone is risky.
Once resident, Thailand largely leaves foreign income alone (remittance basis basis), which is why it appears on lists of friendly destinations for expats and remote workers. The top 35% rate only bites at the highest income band — an average earner pays less.
Foreign pensions and investments
Foreign pension: Taxable as remitted foreign income if brought into Thailand (earned 2024+); LTR-visa pensioners are exempt on remitted foreign income. Foreign capital gains and dividends: Taxable only when remitted to Thailand (earned 2024+); no separate CGT regime for individuals. These outcomes can be overridden by a double-tax treaty, which decides whether the source country or Thailand taxes each stream — a key reason retirees should map their specific income against the relevant treaty.
The Long-Term Resident (LTR) visa regime
The 10-year LTR visa exempts Wealthy Global Citizens, Wealthy Pensioners and Work-from-Thailand Professionals from Thai tax on remitted foreign-source income, and gives Highly-Skilled Professionals a flat 17% PIT rate on employment income.
Special regimes have eligibility tests, time limits and sunset dates that change frequently. Treat the summary above as a starting point and verify the current terms with Thailand's tax authority before relying on it.
US citizens and social security in Thailand
| Question | Thailand |
|---|---|
| US income tax treaty? | Yes |
| US social-security totalization agreement? | No |
| Tax basis for residents | Remittance basis |
| Top personal income tax | 35% |
A US tax treaty with Thailand helps reassign taxing rights and reduce withholding, and US citizens lean on the Foreign Earned Income Exclusion and Foreign Tax Credit to avoid double income tax. With no totalization agreement, you can be exposed to social-security-type charges in both the US and Thailand. See our guides on FEIE vs the Foreign Tax Credit and totalization agreements.
