Thailand has 8 progressive tax brackets from 0% to 35%, with the first ฿150,000 (~$4,200 USD) completely tax-free—generous compared to most countries. But here's the catch: since 2024, foreign income remitted to Thailand in the same year it's earned is now taxable for residents. Previously, expats could avoid tax entirely by waiting a year before remitting. Social security is remarkably low: just 5% capped at ฿875/month (~$24 max contribution, wage ceiling ฿17,500/month). A ฿1,000,000 earner (~$28,000) pays roughly ฿80,900 income tax (~8.1%) plus ฿10,500 SSO — about 9.1% total effective rate. Calculator uses standard deductions: ฿60,000 personal allowance + 50% employment deduction (capped ฿100,000). Married couples and parents get additional allowances (฿60,000 spouse, ฿30,000/child/parent) not included in the base calculation. Thailand's LTR (Long-Term Resident) visa offers 17% flat tax for wealthy individuals and remote workers. No capital gains tax on stocks (except day traders). Filing deadline is March 31 (PND 90/91). Use our calculator to estimate your Thai tax liability.
Note: These are marginal rates — you only pay the higher rate on income within each bracket.

Thailand has 8 brackets: 0% on ฿0-150,000, 5% on ฿150,000-300,000, 10% on ฿300,000-500,000, 15% on ฿500,000-750,000, 20% on ฿750,000-1,000,000, 25% on ฿1-2 million, 30% on ฿2-5 million, and 35% above ฿5 million. The ฿150,000 tax-free threshold means low earners pay nothing.
Major 2024 change: foreign income remitted to Thailand in the same calendar year it's earned is now taxable for tax residents (180+ days in Thailand). Previously, you could defer foreign income by a year and remit tax-free. This affects expats, retirees, and digital nomads. Foreign income earned before 2024 remains exempt when remitted.
The Long-Term Resident (LTR) visa offers 10-year residency with tax benefits. 'Wealthy Global Citizens' (min $1M assets, $80K/year income) and 'Work-from-Thailand Professionals' ($80K/year income, 5 years experience) get 17% flat tax on Thai employment income and exemption on foreign income. Wealthy Pensioners and High-Skilled categories also available.
Thai employees pay 5% social security (ประกันสังคม) on monthly wages of ฿1,650 to ฿17,500, so at most ฿875/month (฿10,500/year)—one of the lowest rates globally. Employers match this 5%. Coverage includes healthcare, disability, maternity, child allowance, old-age pension, and unemployment. Foreign employees in Thailand are also required to contribute. The low cap makes it negligible for high earners.
Stock market gains are generally exempt from capital gains tax in Thailand for individual investors. However, frequent traders may be classified as 'assessable income' and taxed at normal rates. Property gains are taxed at withholding rates based on holding period (reducing over time to ~2.5% after 8+ years). Crypto gains are taxed at 15%.
