Guanajuato → Guanajuato · Autopista 45D Salamanca-Querétaro
The trip back from Salamanca, Guanajuato, to Irapuato, Guanajuato, repeats the short 24 km (15 miles) along Autopista 45D Salamanca-Querétaro, closing out an extra 16m on the dashboard. At metropolitan scale, this kind of return tends to happen multiple times per week, so precise odometer tracking matters for closing the full monthly reimbursement. Anyone returning from Salamanca (the sede de la refinería Ing. Antonio M. Amor de Pemex) reconnects with Irapuato (the capital fresera y nodo logístico intermedio del corredor del Bajío) in just a few minutes. Incremental spend stays at MXN 48.40 for 2 liters. Return reimbursement adds MXN 156.00 to the running total, at the MXN 6.50/km benchmark. Batch several short trips into the same Clara receipt lot to speed up monthly journal posting. The system accepts weekly or biweekly batches, with each individual leg identified by timestamp, opening odometer, and closing odometer, automatically totaling the reimbursement due. Professionals who shuttle constantly between adjacent metropolitan cities typically configure daily phone reminders to log each departure immediately, avoiding later forgetfulness that erodes the cumulative monthly reimbursement value because chronological evidence becomes harder to reconstruct after the fact. For the US professional driving the 24 km (15 mi) between Salamanca and Irapuato, reimbursement of MXN 156.00 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 Salamanca→Irapuato corridor must show date, business purpose, and odometer readings.
