Brazil's tax authority tightened its Sintonia compliance program with amendments that accelerate how taxpayer rankings reflect real-time behaviour. The 21 August 2026 update makes classifications more responsive and transparent, directly rewarding consistent filers and pushing the tax system closer to international standards built on trust rather than punishment.
Brazil’s tax authority, the Federal Revenue Service (RFB), announced on 28 August 2026 that it amended its Tax Compliance Incentive Program through Normative Instruction RFB No. 2,339, issued on 21 August 2026. This revision updates Normative Instruction RFB No. 2,316 (25 March 2026), which operates under Complementary Law No. 225 (8 January 2026).
Sintonia recognises taxpayers who maintain consistent registration, meet filing deadlines, and provide accurate tax documentation. The updates address how the program evaluates and ranks these participants.
Faster assessment of compliance data
The revised instruction streamlines how Sintonia reflects tax information into participant classifications. Previously completed procedures now feed into rankings more quickly, allowing the program to capture a taxpayer’s current compliance standing more accurately. This change sharpens the program’s ability to identify which participants genuinely sustain the compliance habits Sintonia rewards.
Dynamic ranking with real-time accuracy
The Federal Revenue Service introduced mechanisms that revise rankings when significant information changes occur. Rather than maintaining static classifications, the program now refreshes participant standings to mirror actual compliance behaviour. This adjustment increases transparency around how rankings are assigned and removes ambiguity about validity periods.
Clearer seal publication procedures
Updated procedures for publishing the Sintonia seal clarify its legal validity. Taxpayers and the broader business community now receive better information about classification scope and when benefits apply.
The Federal Revenue Service (RFB) framed these changes as alignment with international tax administration practices that emphasise transparency, good faith, and cooperation.
By tightening how compliance gets measured and communicated, the authority aims to reward consistent taxpayer behaviour and create a more predictable business environment.
