Introducing the PNCT
On August 12, 2026, the RFB and CGIBS issued Ato Conjunto RFB/CGIBS nº 5/2026, establishing the Programa Nacional de Conformidade Tributária (PNCT). The goal is to assist taxpayers in adapting to the new obligations under the IBS/CBS model. (gov.br)
Key components:
- Monitoring & alerts: For missing, inconsistent or divergent fields in fiscal documents
- Orientation & corrective action: Notifications rather than penalties during early transition
- Authority of accountants: They can be formally involved in correction and communication processes if authorized by the taxpayer. (gov.br)
Entities that will qualify:
- Those who follow accessory obligations under IBS/CBS law
- That show continuous improvement in document accuracy
- That respond promptly to communications and correct inconsistencies by December 31, 2026. (gov.br)
What’s Protected, What’s Not
- Missing information doesn’t immediately trigger a fiscal procedure, nor does it necessarily remove the right to self-regularization. (gov.br)
- A 60-day window is kept for voluntary correction of inconsistencies. (gov.br)
- But inaction—failing to engage with notices, or missing deadlines—can lead to exclusion from the program and standard penalties.
How Different Entities Should Act
| Entity Type | Key Concern | Strategic Action |
|---|---|---|
| Large company | High volume of documents and risk of errors; many suppliers | Deploy internal compliance audits; assign accountability; use PNCT to buffer during transition |
| SME / Simples | Less internal capacity; fear of penalties | Work with official guidance; signer a formal contract with an accountant; use software with proper templates |
| Digital entrepreneur / nomad | Often remote; may use third-party invoicing or overseas clients | Keep records; ensure invoices contain new required fields; stay on top of API updates and platform compliance |
Timeline of Actionable Steps
- Now until December 2026: prioritize responding to alerts; correcting inconsistencies. Stay in program compliance.
- September 2026: Option windows open for Simples/IBS-CBS choices. Make informed decisions. (gov.br)
- August 28, 2026: Update API credentials. Ensure system readiness. (gov.br)
- Continue forward: Use reporting, monitor guidance from RFB/CGIBS, professional input.
Real-World Example
Empresa Agroverde, a cooperative, had frequent issues with missing IBS/ CBS fields in fiscal docs from suppliers. Under PNCT, they get warning texts and time to self-correct rather than audit risk. Their accountant liaises with RFB to ensure reconciliation before year-end. Their proactive approach ensures compliance without surprises.
Bottom Line Insights
The PNCT serves as a transition buffer, emphasizing prevention and correction over sanction. But it demands active participation— do the updates, pay attention to notices, correct early. The RTC era rewards businesses willing to adapt, not those waiting for perfect rules to emerge.
