Quintana Roo → Quintana Roo · Carretera Federal 307 Tulum-Chetumal
Wrapping up the trip, the homebound leg from Chetumal, Quintana Roo, back to Cancún, Quintana Roo, layers another 416 km (259 miles) onto the odometer along Carretera Federal 307 Tulum-Chetumal and tacks on roughly 4h 37m to the cumulative day. Drivers leaving Chetumal, the capital quintanarroense fronteriza con Belice y puerto del Mar Caribe, usually pull into Cancún, the destino turístico número uno del Caribe mexicano, 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 839.74 for the 34.7 liters (9.2 gallons) burned. Mileage reimbursement for the homeward stretch totals MXN 2704.00 at the MXN 6.50/km benchmark.

For the UK professional driving the 416 km (259 mi) between Chetumal and Cancún, reimbursement of MXN 2704.00 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 Chetumal→Cancún run must be reported via PAYE settlement agreement or it becomes a benefit-in-kind on the employee's tax code.
