Brazil’s CBS tax reform reshapes betting compliance framework

Brazil has advanced its long-term fiscal reform agenda by introducing detailed regulatory provisions for the Contribuição sobre Bens e Serviços, widely known as CBS, through Decree No. 12,955/2025 signed by President Luiz Inácio Lula da Silva. The decree represents another substantial step in the country’s restructuring of its national tax system and has direct implications for betting operators, lottery providers and related gaming businesses functioning within Brazil’s legal market.

This development is part of a broader modernization strategy intended to simplify Brazil’s historically complex consumption tax framework while expanding federal oversight across multiple sectors, including regulated gambling. For betting companies, the reform is especially significant because it introduces new operational, reporting and tax calculation obligations that may materially affect profitability, compliance costs and strategic planning over the coming years.

Brazil’s wider tax reform and the creation of CBS

Brazil’s complementary law no. 214/2025 laid the legal foundation for the creation of CBS alongside the Imposto sobre Bens e Serviços or IBS. These two taxes are designed to gradually replace several older federal and regional consumption taxes, including PIS and Cofins, which have long been criticized for administrative complexity and overlapping obligations.

The CBS and IBS model seeks to create a more standardized value-added taxation structure. Combined, the standard rate is projected to reach approximately 26.5%, although sector-specific treatment may vary according to regulatory classification and applicable special regimes.

For the betting and lottery industry, this reform carries broader implications than simple tax replacement. It effectively integrates gambling businesses into a newly defined compliance ecosystem with distinct tax methodologies tailored to prediction contests and related gaming activities.

New legal classification for betting and prediction contests

Under Decree No. 12,955/2025, betting and lottery operations are classified under a specific tax regime for “prediction contests.” This legal categorization is broad and includes multiple gaming modalities such as:

• Fixed-odds betting
• Horse racing wagers
• Sweepstakes
• Fantasy sports

Fantasy sports are specifically defined within the decree as online contests in which participants assemble teams composed of real-world athletes based on statistical analysis and performance projections.

This legal definition matters because it determines how operators calculate taxable revenue and comply with federal obligations. Rather than taxing total player deposits or betting turnover, Brazil’s framework applies CBS and IBS to gross gaming revenue, commonly referred to as GGR. This means taxation is assessed on operator revenue after prize payouts are deducted.

Gross gaming revenue becomes the core tax base

The use of GGR as a taxation base aligns Brazil with regulatory approaches seen in several international gaming jurisdictions. In practical terms, GGR equals total betting revenue minus player winnings paid out.

However, Brazil’s formula introduces additional layers. Operators must also deduct legally mandated allocations to public funds or designated beneficiaries before arriving at the final taxable base. Following this, municipal services tax obligations, including ISS where applicable, are considered within the formula.

This multi-step methodology reflects Brazil’s attempt to create a comprehensive fiscal structure while preserving existing public financing obligations tied to lottery and betting activity.

The final adjusted tax base therefore represents net operational income generated from gambling-related services under the legal framework.

Rising tax pressure on betting operators

Brazil’s regulatory trend suggests increasing fiscal pressure on betting businesses over time. Current projections indicate that sector-specific taxation on GGR may rise from 12% to 15% by 2028.

When combined with CBS, IBS, corporate income taxes such as IRPJ and CSLL and possible selective taxes, the aggregate burden on operators could approach approximately 42% by 2033 according to current policy direction.

This creates a notable financial consideration for both domestic and international operators seeking long-term market participation. While Brazil’s regulated market offers substantial commercial opportunity due to population size and growing digital adoption, the tax structure may require operators to carefully balance compliance investment against revenue potential.

Selective tax adds another compliance layer

The decree also reinforces the potential application of a selective tax, often described informally as a “sin tax,” on betting activities.

Selective taxation is generally associated with sectors considered socially sensitive or potentially harmful, such as alcohol, tobacco or gaming. Although final rates and implementation specifics may evolve, the inclusion of betting within this category indicates Brazil’s intention to maintain stricter fiscal oversight over gambling operations.

For operators, this means tax exposure could extend beyond standard consumption and corporate frameworks into additional policy instruments intended to regulate market behavior and public welfare concerns.

Corporate obligations remain substantial

Despite the replacement of PIS and Cofins with CBS and IBS, betting companies are not exempt from other major corporate tax responsibilities.

Operators will still remain subject to:

• IRPJ (Corporate Income Tax)
• CSLL (Social Contribution on Net Profit)

Together, these taxes represent a significant percentage of taxable profits. As a result, while the reform simplifies certain tax categories, it does not necessarily reduce the total fiscal burden on licensed betting entities.

This distinction is important for investors and operators evaluating Brazil’s market because simplification should not be mistaken for deregulation or reduced government oversight.

Expanded electronic reporting requirements

One of the decree’s most operationally demanding components is its expanded compliance and reporting structure.

Companies operating under the specific betting regime must submit detailed electronic records covering:

• Bettor identification
• Bet amounts
• Geographic location of wagers
• Prize payments
• Mandatory public allocations
• Export-related transactions

These obligations indicate a broader regulatory emphasis on transparency, anti-fraud enforcement and tax accountability.

Maintaining accurate digital infrastructure will likely become essential for operators, especially multinational platforms managing both domestic and cross-border operations. Failure to comply may create legal or administrative exposure depending on enforcement standards.

Bettor tax treatment and limitations

For individual bettors, the framework establishes a more limited role in CBS taxation.

Prizes won by bettors are excluded from the direct CBS tax base calculation for operators. However, bettors themselves cannot claim CBS credits. This effectively places the primary compliance burden on operators rather than consumers while preserving tax efficiency mechanisms for eligible business expenses.

Negative tax bases may be carried forward for up to five years without adjustment, offering operators some degree of strategic flexibility during lower-performing periods.

Cross-border betting services under Brazilian rules

Brazil’s decree also addresses international betting operations, a particularly important issue in the digital era.

Foreign operators serving Brazilian users are generally expected to comply with CBS obligations under similar standards to domestic providers. In many cases, the foreign service provider becomes the principal taxpayer.

Services offered to users outside Brazil may qualify as export transactions and may therefore avoid CBS liability, provided strict evidentiary standards are met. Required indicators may include:

• IP address verification
• Geolocation data
• Customer non-residency declarations

This framework highlights Brazil’s effort to reduce regulatory arbitrage while preserving competitive neutrality between domestic and foreign businesses.

Strategic implications for the betting market

Brazil’s evolving tax and compliance framework demonstrates a dual policy objective: fiscal modernization and tighter governance of a rapidly expanding betting market.

For licensed operators, the environment presents both opportunity and complexity. Brazil’s scale, consumer base and digital penetration remain commercially attractive. However, the combination of rising tax rates, selective taxation, detailed reporting and cross-border obligations suggests that market participation will increasingly favor well-capitalized businesses with advanced compliance systems.

Smaller operators or companies with limited regulatory infrastructure may face greater entry barriers as implementation progresses.

Conclusion

Brazil’s regulation of CBS through Decree No. 12,955/2025 represents a major institutional shift for the country’s betting and lottery industries. Rather than functioning solely as a tax adjustment, the framework establishes a more structured legal and fiscal ecosystem that integrates gambling into Brazil’s broader economic reform agenda.

The introduction of CBS and IBS, the classification of prediction contests, the use of GGR-based taxation and the expansion of reporting requirements collectively signal a more mature but more demanding regulatory landscape. For operators, this means that legal compliance, tax planning and operational transparency are likely to become just as important as market growth.

As Brazil continues refining its national betting framework, stakeholders will likely monitor future decrees, tax adjustments and enforcement standards closely. The country’s approach may ultimately shape not only domestic market dynamics but also broader perceptions of Latin America’s regulatory evolution in gaming.
