Veracruz → Tlaxcala · Carretera Federal 140 Xalapa-Veracruz
Before turning the key for Tlaxcala, Tlaxcala, on the homeward run from Xalapa, Veracruz, do a quick inventory sweep of onboard equipment: proposal binder, undelivered promotional items, and visitor badge should each go into a separate compartment so nothing slides into the footwell during a sharp brake. Carretera Federal 140 Xalapa-Veracruz accepts the 177 km (110 miles) of the return in roughly 1h 58m. Pulling out of Xalapa (the capital veracruzana y centro universitario de la Sierra Madre Oriental), the road eventually puts the driver back in front of the urban skyline of Tlaxcala (the capital tlaxcalteca y la entidad más pequeña en superficie del país). Refueling sits near MXN 358.16 for the same 14.8 liters (3.9 gallons) at the EIA national average benchmark. Return reimbursement, calculated against MXN 6.50/km, returns MXN 1150.50 into the driver's wallet. Snap the closing odometer with the phone camera and attach it directly to the Clara receipt — internal controls accept photographic evidence without a supplementary spreadsheet. For the US professional driving the 177 km (110 mi) between Xalapa and Tlaxcala, reimbursement of MXN 1150.50 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 Xalapa→Tlaxcala corridor must show date, business purpose, and odometer readings.
