Issuing the CIOT (Código Identificador da Operação de Transporte — Transport Operation Identification Code) remains one of the most critical routines for anyone hiring road freight with independent carriers in Brazil. In 2026, pressure for compliance, traceability, and Electronic Freight Payment (PEF) is set to rise — and enforcement will stay vigilant. If you are a fleet manager, logistics operator, transportation analyst, or work in freight procurement, understanding who must issue CIOT and how to do it without friction is essential to avoid fines, delays, and rework.
In this article, you will clearly see:
- Who is required to issue CIOT in 2026.
- Who is exempt.
- What to monitor in the rules and enforcement trends.
- Best practices to stay risk-free.
- How Meu Rastreio helps you issue CIOT quickly and securely.
What CIOT is and what it is for
The CIOT is a code generated to identify and register each road freight operation when a Transportador Autônomo de Cargas (TAC — independent carrier) or an equivalent TAC is hired. It:
- Links the transport service to a specific contract/freight order.
- Ensures that payment to the TAC is made via an authorized electronic method (PEF).
- Brings transparency to all parties (shipper, carrier, and driver) and to regulators.
- Reduces fraud and safeguards drivers’ rights.
Without a CIOT, payment to a TAC is irregular and the trip can be fined.
Who must issue CIOT in 2026
In short, any freight buyer who hires a TAC or TAC-equivalent for paid road freight must issue CIOT in 2026. This includes:
- Shippers and freight buyers (legal entities) hiring TAC
- Industries, distributors, retailers, e-commerce, and farms (CNPJ) that contract directly with a TAC.
- Applies to both spot routes and recurring contracts.
- Carrier companies (ETC) sub-hiring TAC
- When an ETC takes the freight from the client but executes the trip with an independent carrier, the ETC — as the payer to the TAC — must issue the CIOT tied to that driver’s payment.
- Transport cooperatives (CTC) and logistics operators/agents
- Cooperatives and operators/agents brokering loads with TACs must issue the CIOT and ensure PEF for the driver performing the trip.
- Subcontracts and transshipments involving TAC
- In multi-leg operations, whenever a TAC is paid, the party paying the independent carrier is responsible for generating the corresponding CIOT for that operation.
Bottom line: Hired a TAC? You need a CIOT. Paying a TAC? The CIOT is your responsibility.
Who is exempt from issuing CIOT
In general, the following are exempt:
- Carrier companies (ETC) executing the trip with employee drivers and an owned fleet, without sub-hiring TAC.
- Own-account transport, with no freight charge (for example, a company moving its own goods with its own vehicle).
- Hiring by an individual (non-business) in strictly occasional situations not characterized as an ongoing economic activity. Note: if an individual acts in a way equivalent to a legal entity (habitual economic activity), requirements may apply.
When in doubt, confirm with your legal/accounting advisors and consult the latest ANTT publications.
What to monitor in 2026: rules and trends
While the CIOT foundation remains stable — obligation tied to hiring a TAC and paying via PEF — 2026 should consolidate trends seen in recent years:
- More electronic enforcement: data cross-checks among RNTRC, CT-e, MDF-e, invoices, and CIOT, with near real-time alerts.
- Broader PEF coverage: more authorized electronic methods and fully digital flows for advances, balances, and trip expenses.
- End-to-end traceability: stricter requirements for consistent data (origin/destination, vehicle, driver, plate, amounts and installments), with lower tolerance for discrepancies.
- Effective penalties: significant fines and potential trip holds or temporary impediments in case of irregularities.
- Governance and ESG: global supply chains increasing scrutiny over labor and financial compliance in driver payments.
Practical tip: before each quarter, validate critical points with your CIOT/PEF provider and update internal procedures.
CIOT in practice: when, how, and what to inform
- When to issue: before the trip begins/transport execution.
- One CIOT per operation: every contract/freight order with a TAC must have its own CIOT, covering the agreed payment installments.
- Essential information: buyer details; TAC data (including valid RNTRC); vehicle and plate(s); origin and destination; freight amount; advances and remaining balance; electronic payment method.
- Proof of CIOT/PEF: the driver must carry the CIOT/PEF receipt digitally (or physically) during the trip to present to enforcement if needed.
- Alignment with PEF: the amounts and installments paid must match the CIOT record. Discrepancies trigger fines.
Risks of not issuing (or issuing incorrectly)
- Fines that can add up to thousands of BRL per occurrence.
- Trip holds or impediments during enforcement.
- Freight chargebacks and operational rework.
- Reputational exposure and contractual risk with large shippers.
- Indirect costs: stops, re-deliveries, delays, missed dock windows.
The cost of non-compliance usually far exceeds the investment in the right processes and technology.
Quick application examples
- Seasonal demand in industry: a beverage manufacturer hires TACs for summer peaks. Each trip has a CIOT issued before pickup; advances and balances are paid via PEF. Result: zero fines and predictable driver cash flow.
- Regional cooperative: a CTC deploys 200 TACs on fractional routes. CIOTs are generated in batches, integrating driver, plate, and freight values. Automated audits flag discrepancies before shipping.
- 3PL operator: a logistics provider subcontracts TACs for last-mile routes. The CIOT is linked to the order/picking list and the receipt travels with the driver in the app. Accounting closes the month with 100% PEF reconciliation.

Quick CIOT FAQ for 2026
- Do I need a CIOT per trip or per contract? In general, per operation/freight order with the TAC. Changes in scope, route, or amounts typically require a new record.
- Can I pay the TAC in cash? No. Payment must occur via an authorized electronic method (PEF) and be linked to the CIOT.
- Does the driver need to carry the receipt? Yes. The document (digital or physical) must be accessible during the trip.
- In a subcontract, who issues the CIOT? The party paying the TAC for that operation issues the corresponding CIOT.
Conclusion: 2026 demands agile, 100% compliant processes
In 2026, the answer to “who needs to issue CIOT?” is straightforward: every buyer who hires and pays a TAC or TAC-equivalent. What changes is the level of rigor for accurate data, systems integration, and flawless electronic payments. With the right technology, you turn a risk point into a competitive edge: faster trip releases, fewer stops, and full financial traceability.
