**TL;DR:** Vouchers, bank cards, cash and the authorized wallet compared: only the wallet scores high on CFDI, control, coverage and cost at once.

- Cash is non-deductible by law regardless of the amount.
- Vouchers control the amount issued, not the transaction or liters.
- Bank cards capture only 85-90% of CFDIs through portals.
- The authorized wallet auto-stamps a CFDI on every operation.

## Summary

A 2026 comparison of fuel payment instruments in Mexico: cash is non-deductible by law; vouchers comply with effort but lose on coverage and granularity; bank cards pay well but invoice poorly (85-90% CFDI capture); the SAT-authorized electronic wallet is the only instrument designed for this expense — automatic per-transaction CFDIs, per-unit control and, on open loop, universal coverage.

## Frequently asked questions

### Are fuel vouchers still deductible in 2026?

Yes, if the issuer meets requirements and documentation is complete; but control is by amount issued, not per transaction.

### Is the electronic wallet a fuel credit card?

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