How to calculate your PIT

The PIT calculation is therefore the result of the following formula: Assessable Income – Deductible expenses – Allowances, to which the below progressive tax rates apply:

Taxable income (Baht) Tax rate %
1 - 150,000 Exempt
150,001 - 300,000 5%
300,001 - 500,000 10%
500,001 - 750,000 15%
750,000 - 1,000,000 20%
1,000,001 - 2,000,000 25%
2,000,001 - 5,000,000 30%
5,000,001 and Over 35%

How to submit your PIT?

Tax payers are responsible for filing their annual income tax return to the Revenue Department by March 31st following the taxable calendar year.

Taxes on certain income categories will already have been withheld at source and paid to the Revenue Department by the income payer, such as employment income or professional fees.

Tax payers will therefore credit such tax withheld at source against their tax liability when submitting their annual return (PND.90 and PND.91).
