Colima → Guanajuato · Autopista 54D Colima-Guadalajara
Outside sales reps regularly slot the Colima, Colima, → León, Guanajuato, leg into the weekly visit calendar precisely because the 375 km (233 miles) along Autopista 54D Colima-Guadalajara fit inside 4h 10m of continuous driving and still leave room for a full client meeting before the homeward trip. Pulling out of Colima — the capital colimense en la falda del Volcán de Fuego — the route crosses light industrial zones, then farmland, before opening into León, the capital del calzado y mayor ciudad de Guanajuato. The budget line item calls for 31.3 liters (8.3 gallons) of gasolina Magna (about MXN 757.46 at the national average benchmark of 24.20 MXN/liter), plus discretionary tolls billed per axle. Reimbursement math, against the tarifa promedio de mercado schedule of MXN 6.50/km, returns MXN 2437.50 to the contributor at week-end. To accelerate finance approval, generate the Clara receipt already populated with the visited account number and the open service-order ID from the corporate CRM. For the US professional driving the 375 km (233 mi) between Colima and León, reimbursement of MXN 2437.50 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 Colima→León corridor must show date, business purpose, and odometer readings.
