Tax Law Highlights | The Reduction of Tax Incentives Under Complementary Law No. 224

Why It Matters

The reform curtails Brazil’s tax expenditures, tightening fiscal discipline while reshaping the cost base for corporations and importers. It also creates legal uncertainty, prompting firms to reassess investment incentives and prepare for potential disputes.

Key Takeaways

• LC 224/2025 mandates linear cut of federal tax incentives.
• Reductions start Jan 1 2026 for IRPJ/Import Tax, Apr 1 2026 for others.
• Exemptions now taxed at 10% of standard rate.
• Benefits tied to pre‑2025 investment projects are exempt from cuts.
• Likely surge in litigation over altered taxpayer expectations.

Pulse Analysis

Brazil’s fiscal consolidation agenda gained momentum after the 2021 constitutional amendment that demanded tighter control of mandatory and tax expenditures. Complementary Law No. 224/2025 operationalizes that mandate by imposing a systematic, linear reduction on a broad suite of federal incentives. The legislation reflects a shift from ad‑hoc exemptions toward a more transparent, benchmark‑based tax regime, signaling the government’s intent to align tax benefits with measurable economic outcomes rather than political concessions.

The law’s mechanics rely on a "standard taxation system" as a reference point. Exemptions and zero‑rate benefits are now taxed at just 10% of the ordinary rate, while reduced rates are recalculated using a 90%‑plus‑10% formula. Base‑reduction allowances and deemed credits are similarly capped at 90% of their previous levels. Implementation dates are staggered: corporate income tax (IRPJ) and import duties (II) begin on January 1, 2026, with PIS, COFINS, CSLL and IPI following on April 1, 2026. This phased rollout gives businesses a brief adjustment window but also introduces immediate cost pressures for sectors heavily reliant on these incentives.

For corporations, the reform translates into higher effective tax rates and a reassessment of project viability, especially for investments that were predicated on generous tax breaks. The exclusion clause for projects approved before the end of 2025 offers a narrow safe harbor, but the ambiguity around “burdensome conditions” may spark litigation. Companies are likely to seek judicial clarification and may restructure financing to mitigate the impact. Advisors should monitor emerging case law, as court interpretations will define the practical limits of the new regime and shape Brazil’s investment climate for years to come.
