Tamaulipas → Coahuila · Autopista 85D Monterrey-Nuevo Laredo
Autopista 85D Monterrey-Nuevo Laredo is the backbone for anyone connecting Nuevo Laredo, Tamaulipas, to Saltillo, Coahuila: roughly 341 km (212 miles) of pavement that translate into about 3h 47m at the wheel under favorable conditions. Nuevo Laredo, the principal puerto fronterizo de comercio terrestre con Estados Unidos, gradually slips into the rearview mirror as the landscape shifts from city blocks through rural counties and finally into the metropolitan footprint of Saltillo, the capital coahuilense y centro de la industria automotriz Chrysler. Fleets that slot this leg into a weekly rotation tend to schedule mid-week departures, when truck volume is lighter and weather-related closures are less likely. The engine averages around 28.4 liters (7.5 gallons) of gasolina Magna, which works out to about MXN 687.28 at the 24.20 MXN/liter benchmark. Reimbursement for the outbound run, calculated at MXN 6.50/km, totals MXN 2216.50. Generate the receipt in Clara before stepping out of the vehicle so the expense lands in the same-day close, with zero rework for accounting. For the Canadian professional driving the 341 km between Nuevo Laredo and Saltillo, reimbursement of MXN 2216.50 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 Nuevo Laredo→Saltillo 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.
