The Brazilian Federal Revenue Service has announced changes for the 2026 Income Tax declaration, including the introduction of specific fields for declaring winnings from betting activities, which became mandatory under law 14.790. Taxpayers who earned more than R$ 28,467.20 in bets during the 2025 calendar year will need to report these earnings, providing detailed information about their gambling income. The updates aim to improve transparency and compliance regarding gambling revenues.

The declaration process will begin on April 23, 2026, coinciding with the release of pre-filled returns, and will conclude at 11:59 PM on May 29, 2026. The Federal Revenue has also implemented alerts for taxpayers who may fall into the 'fine mesh' category, detailing potential discrepancies that could require further scrutiny during the review process. These measures reflect a growing emphasis on ensuring the integrity of tax reporting in Brazil.

In addition to mandatory declarations for gambling income, the updates highlight the Brazilian government's renewed focus on regulating the betting industry and enhancing tax collection mechanisms. By requiring detailed records of betting winnings, the authorities aim to curb tax evasion and promote fair tax practices among individuals engaged in online and offline gambling activities. This could have significant implications for both the betting market and the broader economy as accountability increases for taxpayers in this sector.
