Baja California Sur → Sonora · Carretera Transpeninsular 1
The long-haul return between Los Cabos, Baja California Sur, and Hermosillo, Sonora — another 869 km (540 miles) along Carretera Transpeninsular 1 — closes a journey that hardly fits inside a single business day. Reserve another 9h 39m on the schedule and consider a second overnight if departure happens at the close of business hours. Anyone driving back from Los Cabos (the destino turístico de la punta de la península de Baja California) often pulls into Hermosillo (the capital sonorense y sede de la planta automotriz Ford Hermosillo) over the weekend. Incremental fuel adds MXN 1752.08 (72.4 liters / 19.1 gallons). Return reimbursement reaches MXN 5648.50 at the MXN 6.50/km tariff. Reconcile outbound and return inside a single Clara PDF, with hotels itemized as separate line items, so finance can reimburse the full bundle in one batch. Priority processing happens when all supporting documents (fuel invoice, toll receipt, hotel folio, meal receipts) sit attached in chronological order and identified by the originating project number. For trips longer than three days, the finance department may also require an executive visit summary attached, describing objectives achieved, agreed next steps, and the commercial indicators generated. For the US professional driving the 869 km (540 mi) between Los Cabos and Hermosillo, reimbursement of MXN 5648.50 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 Los Cabos→Hermosillo corridor must show date, business purpose, and odometer readings.
