Brazil’s Federal Revenue Service, known as Receita Federal, released new tax guidelines on Tuesday aimed at people who earn money from fixed-odds sports betting and fantasy sports competitions.
The rules explain how bettors should calculate income tax on their winnings. They also lay out the steps for those who want to pay their taxes through an installment plan.
The guidelines cover when income tax kicks in for bettors. They also spell out what documents a bettor needs to provide as proof of their financial results from betting platforms.
When Do Betting Winnings Get Taxed?
Winnings from fixed-odds sports betting and fantasy sports are only taxable when a bettor makes a net profit over the course of a year.
The net gain is figured out by subtracting the total amount a bettor spent in a year from the total amount they won in that same year.
If the net gain comes in above BRL 28,467.20, the amount over that threshold is taxed at a flat rate of 15%. Anything below that amount is not taxed.
To prove their results, bettors need to get a document called “ComprovaBet” from their betting platforms. This document is a summary of every transaction a bettor made during the year.
Betting sites are responsible for providing this document to their users. It serves as the official record for tax purposes.
The Federal Revenue Service also launched a new digital tool for bettors. The tool lets taxpayers calculate their taxable base and the exact amount of income tax they owe.
It is designed for people who received prizes from multiple betting sites or virtual competitions. The tool is available through the agency’s services page.
How the Installment Payment System Works
If the tool shows that a tax payment is due, the bettor can choose to pay in installments. This process is handled through the e-CAC Portal, the agency’s digital platform.
The bettor first calculates what they owe using the services page. They then request a manual registration of the debt by selecting the “Requerimentos Web” option.
The system takes up to five business days to register the debt. Once that is done, the taxpayer can log into the e-CAC portal and apply for installment payments.
During the negotiation stage, taxpayers must select debts tied to revenue code 6313. This code is specifically linked to income tax on prizes from betting activities.
The simplified plan allows taxpayers to split their debt into up to 60 monthly payments. Each payment must be at least BRL 200.
The plan goes into effect after the first payment is made using a payment slip generated at the time of the request.
The Federal Revenue Service said the new guidelines are meant to make it easier for users of betting platforms and virtual gaming competitions to follow the tax rules. The agency released the guidelines on March 10, 2026.
