**TL;DR:** Fuel cards in Mexico: cash kills the deduction; the SAT-authorized wallet issues an automatic CFDI on every fill-up for full deductibility.

- Art. 27 LISR bars deducting fuel paid for in cash.
- The electronic wallet is a payment instrument, never credit.
- Five CFO criteria: CFDI, VAT, network, controls, reconciliation.
- Every fill-up without a CFDI costs 16% VAT plus 30% undeducted ISR.

## Summary

A decision guide for Mexican CFOs on business fuel cards: why cash payments kill the deduction (Art. 27 LISR), how SAT-authorized electronic fuel wallets differ from corporate cards and paper vouchers, the five CFO decision criteria, and how to estimate ROI by comparing lost-CFDI costs against instrument fees.

## Frequently asked questions

### Is fuel paid in cash deductible in Mexico?

No. Art. 27, section III of the LISR requires payment by check, transfer, card or an authorized electronic wallet, even below MXN 2,000.

### Does the electronic fuel wallet grant credit for fuel?

No. It is a SAT-authorized payment instrument the company tops up with its own funds. Credit is a separate product — the CNBV-regulated Línea de Crédito Clara, which can fund the wallet.
