Direct answer: The law allows a buyer under the regular regime to claim presumed credits on eligible purchases from a non-taxpayer rural producer or integrated producer. The producer does not collect regular IBS/CBS on that supply, but the chain does not necessarily lose all credit. Eligibility, rate and documentation must be checked for the transaction date.

Practical framework
| Party | Control |
|---|---|
| Producer | prove status and document the sale |
| Buyer | validate eligibility and calculate the credit |
| Accounting | reconcile invoice, inventory and ledger |
| Legal/commercial | align price and contractual risk |
The basic flow is: verify supplier status, document product/quantity/value, test legal eligibility, apply the current official rate and retain the calculation. It is not a refund to the seller or a free credit. Buyers may price the tax effect, but no credit authorizes a unilateral contract discount.
Retain status evidence, invoice, contract, delivery, classification, payment and any quality report. Key risks are ineligible purchases, duplicates, outdated rates and a supplier that crossed the revenue threshold.
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
Who claims the presumed credit?
The eligible buyer under the regular regime, not the rural seller.
Does every rural purchase qualify?
No. Supplier, buyer, operation and evidence must meet the rule.
Is the percentage permanent?
Do not assume so; check the official act for the tax period.
Can the buyer reduce the agreed price?
Not unilaterally; price remains a contractual matter.
