Direct answer: A rural producer, whether an individual or legal entity, may remain outside the regular IBS/CBS regime when annual gross revenue is below R$3.6 million and no voluntary option is made. At or above the threshold, or after opting in, the producer must manage debits, credits and related obligations. The 2026 transition is specific: automatic classification considers 2024 revenue, not merely current monthly sales.

Practical framework
| Scenario | Main consequence |
|---|---|
| Below threshold, no option | Non-taxpayer under the regular regime |
| At/above threshold | Registration, documents and credit controls |
| Voluntary option | Full chain simulation is essential |
The threshold is not an exemption from every tax and should not be fragmented artificially by farm. Review connected entities, establishments and revenue aggregation rules. Individual status does not automatically exclude the producer, and creating a company does not by itself produce the best outcome.
Documents: revenue history, registrations, contracts, purchase and sales invoices, product classifications, related entities and ERP credit reports. Main risks are using the threshold as a general exemption, ignoring the 2024 transition basis and opting without measuring the buyer’s credits.
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
Does the threshold apply per farm?
Not necessarily; apply the producer-level aggregation rules to the actual structure.
Who entered the regime in 2026?
Decree 12,955/2026 contains a transition test based in part on 2024 revenue.
Can a producer below the threshold opt in?
Yes, subject to legal conditions and a prior debit-credit and cash-flow simulation.
Does a non-taxpayer block all buyer credits?
No. Eligible buyers may claim a presumed credit under the official rules.
