Colima → Jalisco · Carretera Federal 200 Manzanillo-Puerto Vallarta
Driving back into Guadalajara, Jalisco, after wrapping the agenda in Manzanillo, Colima, tends to invite quiet reflection on operational efficiency: 251 km (156 miles) along Carretera Federal 200 Manzanillo-Puerto Vallarta and another 2h 47m behind the wheel, not counting reception time, lobby waiting, and the actual meeting. Anyone returning from the place known as the principal puerto de carga contenerizada del Pacífico mexicano reconnects with Guadalajara — the capital tapatía y segunda metrópoli más grande de México — carrying the dual sensation of a job done and accumulated fatigue. To minimize tiredness, alternate music, a technical podcast and absolute silence each hour. Additional fuel spend on the return runs MXN 505.78 (20.9 liters / 5.5 gallons). Equivalent reimbursement totals MXN 1631.50 at the MXN 6.50/km tariff. On the Clara receipt, log notes about active road work seen along the way — the operations group uses that data to refresh the route's standard time each quarter. For the US professional driving the 251 km (156 mi) between Manzanillo and Guadalajara, reimbursement of MXN 1631.50 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 Manzanillo→Guadalajara corridor must show date, business purpose, and odometer readings.
