Tlaxcala → Morelos · Carretera Federal 117 Tlaxcala-Puebla
Coming back from Tlaxcala, Tlaxcala, to Cuernavaca, Morelos, the return leg also clocks roughly 140 km (87 miles) typically along Carretera Federal 117 Tlaxcala-Puebla, but the traffic picture shifts considerably compared with the outbound segment. Tlaxcala, the capital tlaxcalteca y la entidad más pequeña en superficie del país, fades behind the wheel while the vehicle pushes back toward Cuernavaca, the capital morelense conocida como "la ciudad de la eterna primavera", often after a full day of meetings, site visits, or prospecting calls. Plan 1h 33m plus a generous buffer against evening congestion, particularly on Fridays, holiday eves, or after major sporting events. Driver fatigue is the dominant concern returning home; mandatory rest breaks every two hours are non-negotiable. Fuel spend on the return stays near MXN 283.14 for 11.7 liters (3.1 gallons). The corresponding reimbursement on the way back reaches MXN 910.00 at MXN 6.50/km. Combine both legs on a single Clara receipt to document the full round-trip cleanly, with separate timestamps for transparent audit defense. For the Canadian professional driving the 140 km between Tlaxcala and Cuernavaca, reimbursement of MXN 910.00 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 Tlaxcala→Cuernavaca 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.
