Baja California → Baja California · Carretera Federal 2 Mexicali-Tijuana
Punching Ensenada, Baja California, into the GPS for the trip back from Mexicali, Baja California, the dashboard once again shows the 171 km (106 miles) separating the two cities along Carretera Federal 2 Mexicali-Tijuana and estimates 1h 54m to wrap up the return. Mexicali, the capital bajacaliforniana fronteriza con Calexico y centro agroindustrial del Valle, fades in the rear window while the vehicle picks up the homeward path toward Ensenada, the puerto turístico del Pacífico Norte y capital del Valle de Guadalupe vinícola. Unlike the outbound leg, it pays to walk around the truck before pulling out — fuel level, tire pressure, dashboard alerts and load straps all deserve a fresh look, because there is less slack to absorb a surprise once fatigue has settled in. Topping off the tank costs roughly MXN 346.06 to cover the same 14.3 liters (3.8 gallons) consumed on the way out. The return reimbursement reaches MXN 1111.50 at the MXN 6.50/km benchmark. Before pulling into the driveway, close out the Clara receipt with the final odometer reading: corporate finance accepts the digital file with no wet-ink signature required. For the UK professional driving the 171 km (106 mi) between Mexicali and Ensenada, reimbursement of MXN 1111.50 fits the subsistence allowance regime when paid at or below HMRC AMAP rates of 45p per mile for the first 10,000 business miles in the tax year. UK firms reimburse at HMRC AMAP rates (45p / 25p per mile) so the payment stays free of PAYE and NIC under approved mileage allowance payments rules. Retain a VAT receipt accepted by HMRC for input-tax recovery from the BEIS-tracked forecourt network forecourt used to refuel; His Majesty's Revenue and Customs (HMRC) compliance officers cross-reference fuel VAT receipts with the P11D return when reimbursement exceeds the approved rate. Excess paid above AMAP on the Mexicali→Ensenada run must be reported via PAYE settlement agreement or it becomes a benefit-in-kind on the employee's tax code.
