Guanajuato → Querétaro · Autopista 45D Salamanca-Querétaro
Wrapping up the trip, the homebound leg from Salamanca, Guanajuato, back to Querétaro, Querétaro, layers another 105 km (65 miles) onto the odometer along Autopista 45D Salamanca-Querétaro and tacks on roughly 1h 10m to the cumulative day. Drivers leaving Salamanca, the sede de la refinería Ing. Antonio M. Amor de Pemex, usually pull into Querétaro, the centro logístico del Bajío y sede aeroespacial nacional, with an empty calendar but an inbox of paperwork — toll receipts, fuel invoices, visit reports, and meeting minutes all need to be tagged inside the cab before they get tangled with other paper stacks at the office. Average fuel spend on the return holds near MXN 212.96 for the 8.8 liters (2.3 gallons) burned. Mileage reimbursement for the homeward stretch totals MXN 682.50 at the MXN 6.50/km benchmark.

For the UK professional driving the 105 km (65 mi) between Salamanca and Querétaro, reimbursement of MXN 682.50 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 Salamanca→Querétaro run must be reported via PAYE settlement agreement or it becomes a benefit-in-kind on the employee's tax code.
