Executive Summary
Brazil’s tax agenda this week is dominated by the advancing consumption tax reform, with over one million taxpayers opting into the regular IBS and CBS regime ahead of the October 30 deadline. The Federal Revenue also intensified enforcement through Operation Zero Km in the vehicle sector and Operation Pharmaceuticals II, while expanding cooperative compliance benefits and extending Tax Transaction Notice adherence to December 30.
Important Updates
Consumption Tax Reform: IBS/CBS Regular Regime Adoption Surpasses One Million Taxpayers
The Brazilian Federal Revenue (RFB) announced that more than one million taxpayers have opted into the regular regime of the Tax on Goods and Services (IBS) and the Contribution on Goods and Services (CBS), the dual VAT pillars replacing ICMS, ISS, IPI, PIS, and COFINS under Constitutional Amendment No. 132/2023 and Complementary Law No. 214/2025. The option deadline for the regular regime is October 30, 2026, and the election is irrevocable for the calendar year, made exclusively via the e-CAC portal. Taxpayers who do not opt in remain under transition rules with potentially higher compliance burdens. Updated technical documentation (DeRE version 1.3.0) supports the new reporting layouts, with full implementation scheduled for 2033. Updated RFB figures also show more than 549,000 Simples Nacional requests (deadline October 15, 2026) and over 891,000 regular IBS/CBS requests, with rejection causes including tax debts, cadastral mismatches, and ineligible activities.

Simplified Tax Reform Obligations for Nano-Entrepreneurs and MEIs
Decree No. 13,140/2026 and Resolution CGSN No. 195/2026 introduce immediate simplifications for nano-entrepreneurs and Individual Microentrepreneurs (MEIs) under the IBS/CBS regime. Nano-entrepreneurs with annual revenue up to R$60,000 are exempt from issuing electronic invoices with CBS/IBS highlight, monthly DeRE filing, and maintaining digital tax books (EFD). MEIs benefit from a simplified calculation regime with fixed monthly CBS/IBS amounts embedded in the DAS-MEI payment document. The measures apply to the 2026 transition year and are expected to benefit over 15 million small businesses representing more than 70% of active CNPJs.

Record IRPF Refunds and Taxpayer Right to Prior Orientation
The RFB reported record-breaking Personal Income Tax (IRPF) refund performance in 2026, driven by pre-filled declarations and automated validation. Complementary Law No. 225/2026 enshrines the taxpayer’s right to receive guidance from the tax administration before any audit action, shifting enforcement toward cooperative compliance. Taxpayers notified of inconsistencies may request pre-audit meetings to self-correct without penalties. The Taxpayer Bill of Rights (Carta de Direitos do Contribuinte) is established as a binding instrument.

Large-Scale Joint Judgment Platform for Repetitive Tax Cases
The RFB inaugurated a technological platform enabling the Administrative Tax Courts (CARF and DRJ) to adjudicate over 15,000 similar tax cases in a single session. The system uses AI-assisted case clustering, legal thesis mapping, and automated decision drafting based on precedent, integrating with the e-Processo system while preserving due process. The RFB estimates a 70% reduction in average judgment time for repetitive matters involving tax credits, penalties, or regulatory interpretations.

Operation Zero Km Targets R$745 Million in Improper PIS/COFINS Credits in Vehicle Sector
The RFB launched Operation Zero Km to combat undue PIS/COFINS credits claimed by vehicle dealerships totaling over R$745 million. The investigation, involving 50 auditors across 10 states, analyzed EFD-Contribuições data from 2021–2025 and found dealerships crediting inputs not directly linked to taxed sales, such as showroom construction, advertising, and administrative expenses. Taxpayers face assessments, fines of 75%–150%, and potential criminal charges for fraud.

Operation Pharmaceuticals II Identifies BRL 1.8 Billion in Incompatible Pharmaceutical Credits
On November 3, 2026, the RFB announced Operação Fármacos II, identifying approximately BRL 1.8 billion in tax credits claimed by roughly 1,600 taxpayers incompatible with the pharmaceutical sector’s special regime under Law 10.147/2000 and Normative Instruction RFB 1.867/2019. Companies without qualifying industrial operations improperly accessed credits reserved for manufacturers of medicines, hygiene products, and cosmetics. Taxpayers must regularize by January 20, 2027, through payment or installment of undue credits plus Selic interest and a 20% penalty (reduced to 10% if paid within 30 days), avoiding the 75% fraud penalty. An e-CAC dashboard is available for status consultation.

Taxpayers holding the Confia Seal (A+, A, B ratings) or classified in the top tiers of the Sintonia 3rd cycle 2026 may regularize outstanding federal tax debts without incurring mora (late payment) penalties. Under Law 13.988/2020 and RFB Normative Instruction 2.058/2021, eligible debts can be paid in full or through the Parcelamento Especial de Conformidade (PEC) with up to 84 monthly installments at SELIC interest. Eligible federal taxes include IRPJ, CSLL, PIS, COFINS, IPI, and IOF. The benefit applies only through the e-CAC “Transação Tributária” module and terminates prospectively if the taxpayer loses eligible status.

Federal Revenue Extends Tax Transaction Notice Adherence Deadline to December 30
The RFB extended the adherence period for all open Tax Transaction Notices (Editais de Transação Tributária) to December 30, 2026, at 19:00 Brasília time. Substantive terms remain unchanged, including discounts up to 100% on penalties and interest, and installment periods up to 145 months for micro/small enterprises and 84 months for others. Taxpayers may migrate from prior parcelamentos (e.g., Pert, Refis) to more favorable edital terms. Adherence is completed via e-CAC, requiring a down payment (typically 1–4% of consolidated debt) by the deadline to perfect the agreement. Edital PGDAU 3/2026 is relevant for large taxpayers with IRPJ/CSLL disputes exceeding BRL 15 million.
