Guanajuato → Guanajuato · Autopista 45D Irapuato-Salamanca
The short hop between Irapuato, Guanajuato, and Salamanca, Guanajuato — barely 24 km (15 miles) along Autopista 45D Irapuato-Salamanca — fits the metropolitan rhythm of anyone who alternates between office and customer multiple times a week. Under normal conditions the leg burns about 16m, but rush-hour congestion can double that figure. Pulling out of Irapuato (the capital fresera y nodo logístico intermedio del corredor del Bajío) toward Salamanca (the sede de la refinería Ing. Antonio M. Amor de Pemex), fuel spend is minimal: roughly MXN 48.40 for 2 liters. Even so, mileage reimbursement at MXN 6.50/km covers vehicle wear and yields MXN 156.00 on the outbound — it pays to log even short hops on the Clara receipt for cumulative monthly close. Anyone repeating this route more than five times per month should consider opening a supplementary mileage spreadsheet with date, time, business purpose, and contact attended at each visit, attaching it to the final receipt to reinforce evidence of effective commercial use of the vehicle. Internal audit typically requires that level of granularity for accumulated reimbursements above one thousand dollars per month. For the UK professional driving the 24 km (15 mi) between Irapuato and Salamanca, reimbursement of MXN 156.00 fits the subsistence allowance regime when paid at or below HMRC AMAP rates of 45p per mile for the first 10,000 business miles in the tax year. UK firms reimburse at HMRC AMAP rates (45p / 25p per mile) so the payment stays free of PAYE and NIC under approved mileage allowance payments rules. Retain a VAT receipt accepted by HMRC for input-tax recovery from the BEIS-tracked forecourt network forecourt used to refuel; His Majesty's Revenue and Customs (HMRC) compliance officers cross-reference fuel VAT receipts with the P11D return when reimbursement exceeds the approved rate. Excess paid above AMAP on the Irapuato→Salamanca run must be reported via PAYE settlement agreement or it becomes a benefit-in-kind on the employee's tax code.
