San Luis Potosí → Aguascalientes · Autopista 57D México-San Luis Potosí
Wrapping up the trip, the homebound leg from San Luis Potosí, San Luis Potosí, back to Aguascalientes, Aguascalientes, layers another 172 km (107 miles) onto the odometer along Autopista 57D México-San Luis Potosí and tacks on roughly 1h 55m to the cumulative day. Drivers leaving San Luis Potosí, the capital potosina y nodo logístico que conecta el Bajío con el norte del país, usually pull into Aguascalientes, the centro automotriz Nissan y capital del Bajío occidental, 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 346.06 for the 14.3 liters (3.8 gallons) burned. Mileage reimbursement for the homeward stretch totals MXN 1118.00 at the MXN 6.50/km benchmark.

For the Canadian professional driving the 172 km between San Luis Potosí and Aguascalientes, reimbursement of MXN 1118.00 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 San Luis Potosí→Aguascalientes 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.
