Tamaulipas → Nuevo León · Autopista 40D Reynosa-Monterrey
Driving back into Monterrey, Nuevo León, after wrapping the agenda in Reynosa, Tamaulipas, tends to invite quiet reflection on operational efficiency: 261 km (162 miles) along Autopista 40D Reynosa-Monterrey and another 2h 54m behind the wheel, not counting reception time, lobby waiting, and the actual meeting. Anyone returning from the place known as the frontera con McAllen y polo maquilador del noreste fronterizo reconnects with Monterrey — the centro industrial del norte y motor manufacturero del país — carrying the dual sensation of a job done and accumulated fatigue. To minimize tiredness, alternate music, a technical podcast and absolute silence each hour. Additional fuel spend on the return runs MXN 527.56 (21.8 liters / 5.8 gallons). Equivalent reimbursement totals MXN 1696.50 at the MXN 6.50/km tariff. On the Clara receipt, log notes about active road work seen along the way — the operations group uses that data to refresh the route's standard time each quarter. For the Canadian professional driving the 261 km between Reynosa and Monterrey, reimbursement of MXN 1696.50 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 Reynosa→Monterrey 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.
