Baja California Sur → Durango · Carretera Transpeninsular 1
Before turning the key for Durango, Durango, on the homeward run from La Paz, Baja California Sur, 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 Transpeninsular 1 accepts the 718 km (446 miles) of the return in roughly 7h 59m. Pulling out of La Paz (the capital sudcaliforniana sobre el Mar de Cortés y nodo del ferry Topolobampo-La Paz), the road eventually puts the driver back in front of the urban skyline of Durango (the capital duranguense y enlace clave del corredor transversal Mazatlán-Matamoros). Refueling sits near MXN 1447.16 for the same 59.8 liters (15.8 gallons) at the EIA national average benchmark. Return reimbursement, calculated against MXN 6.50/km, returns MXN 4667.00 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 718 km (446 mi) between La Paz and Durango, reimbursement of MXN 4667.00 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 La Paz→Durango corridor must show date, business purpose, and odometer readings.
