What changed in detail
Ato Técnico Conjunto RFB/SUFIS/CGIBS/Diretoria-Executiva nº 8 of 29 September 2026 approves updated CBS/IBS technical documentation for the NF-e (model 55) and NFC-e (model 65):

It also approves NT 2026.004 v1.00 for the CT-e, NFCom, BP-e, NF3e, NFAg and NFGas.
Ato Técnico Conjunto nº 7 of 28 September 2026 does the same for the NFS-e (NT SE/CGNFS-e 009 v1.01) and the NFS-e Via (NT 010 v1.00).
Both acts take effect on publication in the Diário Oficial da União and on the CGIBS website.
What it means
These acts change the technical specifications that issuers and software vendors must follow, so they are a schema and DANFE task rather than a policy change. Update NF-e, NFC-e, CT-e and NFS-e schema validation and DANFE generation to the approved note versions, then re-test the CBS and IBS fields.
The acts supplement earlier notes rather than replace them: NT 2025.002, previously recorded at v1.40 in br-nfe-nota-tecnica-140-rtc-2026, is now at v1.52. Check your platform provider’s release schedule against the new versions.
