Thai Lottery Taxes & Stamp Duty
Thai lottery winnings are taxed very lightly compared with many countries, but there are deductions, and they differ between the Government Lottery and the Charity Lottery. This guide explains what comes off a prize and what does not. Tax rules can change, so treat this as general information and confirm current figures with the Government Lottery Office or the Thai Revenue Department.
The headline: stamp duty
The main deduction on a Thai lottery prize is stamp duty, charged on the winnings:
- Thai Government Lottery (the standard ticket): 0.5%.
- Thai Charity Lottery: 1%.
The 0.5% figure is the same thing as the often-quoted rate of 1 baht for every 200 baht of prize money. So a ฿2,000 last-two-digit win has roughly ฿10 of duty deducted, and a ฿6,000,000 first prize has about ฿30,000 of duty.
It applies to every prize
The duty is charged on all winnings, including small prizes paid in cash by a vendor. When a vendor pays out a small prize, they are responsible for collecting the duty and passing it on, so you may simply receive the net amount.
Vendor commission is not a tax
If you cash a small prize with a street vendor, they often keep a commission (commonly around 1–2%) for the convenience of immediate cash. That is a private service charge, not a government tax, and it is separate from the stamp duty. You can avoid it by claiming through an official GLO office, though that is less convenient for a small amount.
Is there income tax on lottery winnings?
For the official Thai lotteries, the stamp duty described above is the deduction taken at the point of claim; there is no additional Thai lottery-specific income tax layered on top of it for the standard ticket. However, tax law is detailed and individual circumstances vary, so if a large win could affect your overall tax position you should take professional advice.
If you are a foreign winner
Foreign nationals can claim Thai prizes on the same terms, with the same stamp duty. The complication is your home country: many countries tax worldwide income or foreign lottery winnings, and you may need to declare the funds when bringing large amounts across a border. Keep the official receipt from the GLO as proof, and check your own country’s rules with a local tax adviser.
Keep your paperwork
When you claim, especially for a larger prize, you receive official documentation of the win and the duty paid. Keep it — it is your evidence of where the money came from and what was deducted. For the full claiming walkthrough, see How to Claim a Prize.
