In most Latin American countries, online betting winnings are taxed, but who pays and how changes by country: in some the operator withholds the tax before paying you, and in others you must declare the winnings in your annual return. This is the map by country.

Countries where the operator withholds the tax

In Colombia, when a user wins a sports bet a 20% withholding applies on the prize value under the rate in force for 2026, according to Yahoo Noticias. In Mexico, licensed betting houses apply a federal income tax withholding on prizes, according to Casasdeapuestas.io. In these cases you receive the net prize and have no further paperwork.

Countries where you must declare yourself

In Chile, international online casinos do not withhold taxes at withdrawal: you receive the full amount, but you must declare the winnings to the SII if they exceed the annual threshold, according to Chile Casino Guide. In Brazil, the Receita Federal requires declaring in the 2026 income tax return the fixed odds betting prizes obtained during 2025 and the balances held in gaming accounts at year end, according to Focus Gaming News.

Peru and Argentina

In Peru, the tax created by Law 31557 levies the operation of remote gaming, meaning the operator, not the player directly, according to SUNAT. In Argentina, taxation depends on the province and is mainly discussed on the operator side, although regular winnings can fall under the income tax.

Practical advice

Keep the deposit and withdrawal history of each platform and consult an accountant if your yearly winnings were significant: the rules change fast and the obligation usually falls on the player even when the site is foreign.

Frequently asked questions

Do I pay taxes if the casino is foreign? It depends on the country, but the trend is yes: Chile requires declaring winnings from international casinos above the threshold, and Brazil requires declaring prizes and balances even when the platform is foreign, according to Chile Casino Guide and Focus Gaming News.

What happens if I do not declare the winnings? You risk fines and interest when the tax authority cross checks data with operators or banks. In Brazil, for example, the Receita Federal already monitors betting winnings, according to Focus Gaming News.

Does the operator report my winnings to the tax authority? In regulated markets, licensed operators report to the authority, and in countries like Colombia the withholding is applied at source, according to Yahoo Noticias. Assume your winnings are visible to the tax office.
