From 1 August 2026, all major Brazilian e-tax documents must include CBS and IBS information. From 3 August 2026, general regime taxpayers must report IBS/CBS groups in NF-e and NFC-e or face document rejection in production. Affected documents: NF-e, NFC-e, NFS-e, CT-e, CT-e OS, BP-e, MDF-e, NFCom, NF3e, GTV-e, DC-e.
Receita Federal and the CGIBS approved Joint Act RFB/CGIBS No. 4/2026 on 30 July 2026, setting a phased schedule for when each electronic tax document must start carrying CBS and IBS information. Mandatory dates vary by document type and roll out between 3 August 2026 and 1 January 2027. Technical Note 2025.002-RTC v1.40 is the operative specification: from 3 August 2026 companies under the general tax regime must report IBS and CBS groups in NF-e and NFC-e. For the new NF-e model covering IBS/CBS taxpayers that are not ICMS contributors, the mandatory start is 1 December 2026, with technical specifications for that model and the NFS-e for digital platforms due by 1 September 2026. The XML now carries separate elements for CBS base, rate and amount, the same three for IBS, and IS values where applicable, alongside the existing ICMS and PIS/COFINS nodes.
Brazil's dual VAT tax reform takes effect 1 January 2026. NFC-e (digital fiscal receipts) can only be issued to individual consumers; B2B sales must use NF-e (Model 55). IBS/CBS tax fields added to e-invoice layouts via Technical Note 2025.002 — penalty waiver Jan-Apr 2026 for missing data in IBS/CBS fields. Full enforcement of IBS/CBS reporting from 1 August 2026 for general regime taxpayers; Simples Nacional / MEI from 2027.
