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 Canadian professional driving the 416 km between Chetumal and Cancún, reimbursement of MXN 2704.00 stays excluded from T4 employment income provided the per-kilometre rate matches the CRA's reasonable allowance benchmark for the province. Canadian employers typically reimburse at the CRA reasonable per-kilometre rate (61¢ for the first 5,000 km in 2024) so the payment is excluded from T4 employment income. Keep the GST/HST-compliant fuel receipt from any NRCan-tracked retail network station used during the trip — Canada Revenue Agency (CRA) auditors regularly verify fuel-receipt GST/HST when reviewing T2200 declarations of conditions of employment. The Chetumal→Cancún mileage must be logged with date, business purpose, opening and closing odometer readings inside the corporate expense system before month-end close to remain deductible.
