Direct answer: From 2026 through 2033, agribusinesses must operate the transition, not only study it. A minimum plan covers status, registrations, products, documents, credits, contracts, pricing, cash, technology and governance. Every task needs an owner, evidence and a retest date.
This article belongs to the Agribusiness category, the Tax Reform track, and expands the Agribusiness Tax Reform pillar.
Practical framework
| Workstream | Verifiable output |
|---|---|
| Status | map of taxpayer/non-taxpayer producers |
| Products | reviewed NCM, description and treatment |
| Fiscal | tested invoice, return and contingency scenarios |
| Credits | matrix by supplier and evidence |
| Cash/ERP | harvest projections and integration tests |
In 2026, confirm status, registrations, layouts and tests. Before 2027, prepare the individual identifiers and CBS documents covered by the official timetable. From 2029, monitor gradual ICMS/ISS reduction and IBS expansion; in 2033 the planned replacement is completed. Reconfirm dates whenever legislation changes.
Keep operation inventories, agreements, XML, product records, calculation memoranda, ERP test logs, training and contingency plans. A checked box without evidence is not an audit trail.
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.
