Brazil’s Federal Revenue launches IRPF calculator app for betting and fantasy sports winnings

New digital tool uses ComprovaBet data to help individuals calculate income tax on annual net prizes; amounts above R$ 28,467.20 are taxed at 15%, with payment due by the last business day of April.

Brazil’s Federal Revenue (Receita Federal do Brasil) has released a new digital application designed to help individuals calculate the Personal Income Tax (IRPF) due on net prizes earned through fixed-odds betting (“bets”) and virtual competitions such as fantasy sports. The tool was made available on March 2, 2026, as part of the government’s push to standardize tax compliance in the newly regulated segment.

According to Receita Federal, taxpayers should base their calculation on ComprovaBet (Comprovante de Resultados em Apostas em Loterias de Quota Fixa) — the official statement consolidating a player’s results from the previous calendar year. Operators (the agents responsible for betting platforms and fantasy competitions) must provide ComprovaBet to bettors and participants by the last business day of February of the following year.

The rule applied by the tool is straightforward: 15% income tax is charged on the portion of annual net prizes that exceeds R$ 28,467.20, while net amounts at or below that threshold remain exempt. If the calculation shows tax due, the taxpayer must generate a DARF (Documento de Arrecadação de Receitas Federais) and pay it by the last business day of April. Receita Federal also published a user manual alongside the app to guide taxpayers through the process.

For the market, the move signals two clear priorities: simplifying reporting for individuals while strengthening the government’s ability to verify declarations through standardized data (ComprovaBet). The practical outcome is that Brazilian bettors and fantasy players will need to treat winnings more like a formal, annual tax item — and operators will face growing pressure to ensure accurate, timely statements.

Outlook: with an official calculator now in place, Brazil is tightening the “last mile” of enforcement — making it easier to pay correctly, and harder to ignore the obligation.
