Campeche → Yucatán · Carretera Federal 180 Campeche-Mérida
What does it actually cost to drive from Campeche, Campeche, to Mérida, Yucatán? The hard numbers: 200 km (124 miles) of pavement primarily along Carretera Federal 180 Campeche-Mérida, 2h 13m behind the wheel, and roughly MXN 404.14 in fuel alone — that is 16.7 liters (4.4 gallons) of gasolina Magna at a 24.20 MXN/liter benchmark. Anyone leaving Campeche, the capital campechana y patrimonio amurallado de la UNESCO sobre el Golfo, typically carries samples, signed proposals, or service equipment to deliver in Mérida, the capital yucateca y puerta de entrada a la Riviera Maya, 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 1300.00. 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 200 km (124 mi) between Campeche and Mérida, reimbursement of MXN 1300.00 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 Campeche→Mérida corridor must show date, business purpose, and odometer readings.
