Original official news date: . Implementation update, reviewed 12 October 2026.
On 9 October, the Finance Ministry reported that 86% of fiscal documents issued by obligated businesses in the preceding 30 days showed CBS. Among issuing establishments subject to the obligation, 67% showed CBS on all or some documents; those measures are different. The dataset was updated on 8 October and covers documents through 7 October. Simples Nacional businesses are outside this 2026 obligation and calculation. This is an implementation report, not a new rule. Finance teams should sample their own document types, investigate missing fields and reconcile exceptions with ERP configuration. National adoption figures cannot establish whether an individual company’s output is complete.
What to check
Assign a finance owner to review a sample across applicable fiscal document types and establishments. Reconcile missing fields to system settings, retain evidence of corrections and retest the output. This practical control recommendation does not create a new legal deadline.

The official report was published on 9 October. Its dashboard was updated on 8 October, using documents issued through 7 October. These data dates do not change the commencement or scope of the underlying rules.
