Veracruz → Puebla · Carretera Federal 180 Coatzacoalcos-Villahermosa
What does it actually cost to drive from Coatzacoalcos, Veracruz, to Tehuacán, Puebla? The hard numbers: 390 km (242 miles) of pavement primarily along Carretera Federal 180 Coatzacoalcos-Villahermosa, 4h 20m behind the wheel, and roughly MXN 786.50 in fuel alone — that is 32.5 liters (8.6 gallons) of gasolina Magna at a 24.20 MXN/liter benchmark. Anyone leaving Coatzacoalcos, the puerto petroquímico del sur de Veracruz y enlace del Corredor Interoceánico, typically carries samples, signed proposals, or service equipment to deliver in Tehuacán, the segunda ciudad poblana y polo avícola y embotellador del centro-sur, and aims to be home the same evening. It is worth confirming whether the haul fits inside your daily hours-of-service window or whether an overnight at a midpoint hotel makes more sense. Applying the tarifa promedio de mercado mileage rate of MXN 6.50/km (MXN 10.46/mile), the gross outbound reimbursement settles at MXN 2535.00. Attach the visit purpose, client name, and plate number to the Clara receipt so the journal entry lands directly in the business-travel expense account. For the US professional driving the 390 km (242 mi) between Coatzacoalcos and Tehuacán, reimbursement of MXN 2535.00 stays non-taxable to the employee when the employer follows an accountable plan under Treas. Reg. §1.62-2 and reimburses at or below the IRS standard mileage rate. US employers generally reimburse at the IRS standard mileage rate so the payment stays non-taxable to the employee under Pub. 463. Keep the IRS-compliant expense report (Form 1040 Schedule C, line 9) alongside the fuel receipt from any EIA-tracked retail station network pump used along the leg; Internal Revenue Service (IRS) examiners pull contemporaneous mileage logs first when auditing Schedule C unreimbursed business expenses, and the Coatzacoalcos→Tehuacán corridor must show date, business purpose, and odometer readings.
