Review tax credits before enforcement.
Coverage: 14–20 September 2026. Tax-credit controls lead this edition, alongside CBS testing, cooperative elections and funding assumptions.
- Enforcement campaign · Announced 15 September
PIS/Cofins credits: review before 10 November
Receita Federal announced a campaign covering R$1.3 billion in identified PIS/Pasep and Cofins credit inconsistencies. Affected taxpayers may correct the issues by 10 November 2026, before this campaign’s formal audit procedures.
The two targeted risks concern credits treated as inputs in goods resale and freight services supplied by Simples Nacional companies. Notices went by post and to e-CAC mailboxes, or through e-Mac for taxpayers under differentiated monitoring. This is an enforcement initiative, not a new blanket prohibition on Simples-related credits.
Suggested action: Reconcile notices with invoices, freight contracts, supplier status and EFD-Contribuições. Document the basis for correcting or maintaining each credit.

- Scheduled technical releases · Published 14 September
CBS APIs: prepare pilot and beta integration
Receita Federal published documentation for free CBS APIs covering debits, credits, payments, purchaser remittances and DARF issuance. Incremental queries will return new or modified records since the previous request.
Availability is scheduled in Produção Restrita, the CBS pilot, and Produção Beta: debit and credit queries in early October, payments and purchaser remittances in early November, and DARF issuance in late November. This is not a general mandatory production migration deadline.
Suggested action: Confirm the ERP provider’s testing plan and assign responsibility for reconciliation, exceptions and release approval.

- Optional election · Guidance published 18 September
Cooperatives: complete both election steps
Cooperatives covered by article 271 of Complementary Law 214/2025 may elect the specific IBS/CBS regime for 2027 between 1 September and 31 October 2026. Zero rates apply only to transactions expressly covered by law.
The procedure requires registering the choice and submitting members’ identification and admission dates. Registration alone is insufficient. The election takes effect on 1 January 2027 and may be cancelled through 31 October.
Suggested action: Assess credit, pricing and cash-flow effects; validate membership data and retain evidence of both steps.
- Monetary policy · Announced 16 September
Selic: refresh funding assumptions
Copom reduced the Selic target from 14.00% to 13.75% per year, effective 17 September. The committee retained a restrictive stance and made further calibration dependent on new information.
Suggested action: Refresh cash-flow scenarios, check contractual repricing dates and compare deposit and borrowing terms. The policy change does not guarantee an equivalent reduction in individual financing costs.
