Direct answer: In 2026, producers must continue issuing the documents already required by state law while preparing systems for IBS/CBS fields and validations. For individual CBS taxpayers covered by the official notice, the new regulated document effects begin on January 1, 2027. This does not cancel NF-e, NFP-e or existing state obligations.

Practical framework
| Operation | Critical evidence |
|---|---|
| Sale of production | issuer, establishment, product, NCM and buyer |
| Purchase from non-taxpayer | valid evidence for the buyer’s presumed credit |
| Export | invoice, customs and shipment reconciliation |
| Barter/forward delivery | contract, valuation and delivery trail |
Clean CPF/CNPJ, state registrations and addresses; validate NCM and units; distinguish taxpayer and non-taxpayer suppliers; test cancellation, returns and contingency; and preserve XML, contracts and delivery evidence. Layouts and validation rules can be versioned, so the National NF-e Portal and competent tax authority remain the operational sources.
Classification errors, mismatched issuers or missing XML may block credits and trigger rejection. Obtain accounting support for multiple establishments and legal support for barter, exports or integration agreements.
When professional review matters
Use an accountant to validate status, bookkeeping, documents, credits and systems. Add legal counsel when contracts, related entities, cooperatives, exports, integrations or disputed classifications can change liability.
Frequently asked questions
Will every rural invoice show IBS/CBS in 2026?
No. Distinguish testing, informational fields and actual collection under the official transition.
Does NF-e replace every state document?
Not automatically; the state, operation and official calendar matter.
Must XML files be retained?
Yes. They support bookkeeping, credits and audits.
Does an individual need a CNPJ?
For covered CBS cases, the new identifier effect begins in 2027; existing identification remains valid in 2026.
