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 ฿750/month (~$21 max contribution). A ฿1,000,000 earner (~$28,000) pays roughly ฿83,000 income tax (~8.3%) plus ฿9,000 SSO — about 9.2% 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).
