Thailand Personal Income Tax 2026

Reviewed September 2026
Thailand taxes personal income at progressive rates from 0% to 35%, applied to your net income after expenses and allowances. The rates are set by the Revenue Code and administered by the Revenue Department, and they are unchanged for the 2026 tax year, which covers income earned between 1 January and 31 December 2026.

Net income (baht a year) Tax rate
0 to 150,000 Exempt
150,001 to 300,000 5%
300,001 to 500,000 10%
500,001 to 750,000 15%
750,001 to 1,000,000 20%
1,000,001 to 2,000,000 25%
2,000,001 to 5,000,000 30%
Over 5,000,000 35%

Each rate applies only to the part of your income that falls within its band, so someone with a net income of 800,000 baht pays 20% on the last 50,000 baht, not on the whole amount. Our personal income tax calculator applies the table to your own figures.

Foreigners pay the same rates as Thai nationals. Tax residents are taxed on income from Thai sources and on foreign income earned from 2024 onwards when it is brought into Thailand, while non-residents pay only on Thai-source income. Residency and foreign income are covered in Thailand income tax for foreigners.

Before any allowance, each type of income carries a standard expense deduction. Contract and business income may deduct actual expenses instead, where they are higher and documented.

Copyright income 50%, up to 100,000 baht
Rent from buildings or vehicles 30%

Rent from other property 10%

Law, engineering, architecture, accounting and fine arts 30%, or actual expenses
Contract work 60%, or actual expenses
Business and trading income 60%, or actual expenses

Other qualifying donations are deductible at the amount given. Both are capped at 10% of your income after expenses and allowances, and donations to a political party are deductible up to 10,000 baht.
