Lottery Prize Tax in Thailand: Stamp Duty vs. 1% Withholding

💡 Key takeaways

A 6 million baht prize is subject to different deductions depending on the lottery type. See the calculation and check the relevant ticket terms.

A video compares a 6 million baht prize from a standard government lottery with a charitable lottery. The deductions differ by ticket type. The figures below follow information published by Thailand’s Government Lottery Office (GLO), accessed on 16 October 2026. Check the conditions printed on the specific ticket and the current GLO guidance before claiming a prize.

Different lottery types have different deductions

GLO states that a government lottery prize is subject to stamp duty of 1 baht for every 200 baht of prize money, or any fraction of 200 baht. A charitable lottery prize is subject to 1% withholding tax. The GLO’s prize-claim FAQ provides further details.

Charitable lottery1% withholding tax60,000 baht withheld; 5,940,000 baht remaining

These examples apply the stated rates to a 6 million baht prize only. They do not account for other payment conditions or costs and are not a substitute for checking the actual ticket.

Before claiming a prize, check three things

GLO says prizes are paid after the applicable duty or tax is deducted. Its FAQ describes different claim periods for government and charitable lotteries, so do not apply one type’s rules to another.
