You’re correct that Mexico offers one of the lowest lottery tax rates in Latin America. As of current regulations:

Giantlottos
Lottery tickets for:
- Euromillions
- Eurojackpot
- American lotteries

TheLotter
Lottery tickets for:
- Triple Ch Clasico
- Chispa Boom
- Mexlotto Vintage

- American lotteries
- Eurolottery
- Brasil
- Lottery winnings are taxed at 7%, withheld directly by the lottery operator—no separate tax return is required.
- The funds are collected by the lottery organization and remitted to the appropriate authority, whether local or federal.
This makes Mexico stand out for having a notably low withholding tax on lottery prizes.
2. Casino & Slot Game Taxation in Mexico
Regarding casinos and slots, the taxation structure is quite different:
A. Player Winnings
- Casino and slot winnings are taxable. The standard withholding tax rate is 10%, which operators deduct at the time of payout.
B. Operator Taxes
- Casinos themselves face heavy taxation:
- 30% tax on gross gaming revenue (i.e., total bets minus payouts), and
- Another 30% in revenue taxes on top, significantly impacting operators’ profitability.
3. Clarifying the 17% Casino Tax Claim
You mentioned that in Cancun, there’s a “10% tax on the amount you put on the card” and “7% when leaving the casino,” totaling 17%. While this claim may exist anecdotally—possibly referring to a combination of player withholding and internal fees—there is no authoritative evidence supporting a mandatory additional 7% “exit tax” on casino play.
Official sources confirm only the 10% tax on winnings and substantial operator-level taxes—not any additive 7% “tax on exit.”
Summary Table
| Category | Player Tax Withheld | Notes |
|---|---|---|
| Lottery Winnings | 7% | Withheld by lottery provider, one of the lowest in Latin America. |
| Casino & Slot Winnings | 10% | Withheld at payout from winnings. |
| Casino Operator Taxes | ~30% + 30% revenue | Hefty tax burden on gaming operators. |
| Rumored “17% Exit Tax” | Unverified | Not supported by official sources. Potentially a local practice or misunderstanding. |
7% tax on lottery winnings
- You’ll pay 7% tax on lottery winnings, which is indeed quite low.
- Casino winnings face a 10% withholding tax, but there is no recognized 7% “exit tax”.
- The heavy taxation burden lies mostly on operators, not players.
If you’d like, I can help verify whether any specific casinos in Cancun impose additional fees or local levies, though these would be unusual for formal tax structures.
While you may not get your Mexican lottery winnings 100% tax-free, Mexico has the lowest tax rate in Latin America at only 7% in 2023. Taxes are withheld directly by the lottery organization and the local or federal government where the lottery is drawn.
How much are casino taxes in Mexico?
In Cancun, however, they initially tax 10% on the amount you put on the card and believe it or not when you leave the casino, they text you the remaining 7% for a total of 17%. The privilege of playing their slot machine.
