Baja California → Chihuahua · Carretera Federal 2 Mexicali-Tijuana
The long-haul return between Mexicali, Baja California, and Ciudad Juárez, Chihuahua — another 1062 km (660 miles) along Carretera Federal 2 Mexicali-Tijuana — closes a journey that hardly fits inside a single business day. Reserve another 11h 48m on the schedule and consider a second overnight if departure happens at the close of business hours. Anyone driving back from Mexicali (the capital bajacaliforniana fronteriza con Calexico y centro agroindustrial del Valle) often pulls into Ciudad Juárez (the frontera con El Paso y mayor polo maquilador del norte fronterizo) over the weekend. Incremental fuel adds MXN 2141.70 (88.5 liters / 23.4 gallons). Return reimbursement reaches MXN 6903.00 at the MXN 6.50/km tariff. Reconcile outbound and return inside a single Clara PDF, with hotels itemized as separate line items, so finance can reimburse the full bundle in one batch. Priority processing happens when all supporting documents (fuel invoice, toll receipt, hotel folio, meal receipts) sit attached in chronological order and identified by the originating project number. For trips longer than three days, the finance department may also require an executive visit summary attached, describing objectives achieved, agreed next steps, and the commercial indicators generated. For the UK professional driving the 1062 km (660 mi) between Mexicali and Ciudad Juárez, reimbursement of MXN 6903.00 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→Ciudad Juárez run must be reported via PAYE settlement agreement or it becomes a benefit-in-kind on the employee's tax code.
