Baja California → Baja California Sur · Carretera Federal 2 Mexicali-Tijuana
The long-haul return between Mexicali, Baja California, and La Paz, Baja California Sur — another 1335 km (830 miles) along Carretera Federal 2 Mexicali-Tijuana — closes a journey that hardly fits inside a single business day. Reserve another 14h 50m 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 La Paz (the capital sudcaliforniana sobre el Mar de Cortés y nodo del ferry Topolobampo-La Paz) over the weekend. Incremental fuel adds MXN 2693.46 (111.3 liters / 29.4 gallons). Return reimbursement reaches MXN 8677.50 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 1335 km (830 mi) between Mexicali and La Paz, reimbursement of MXN 8677.50 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→La Paz run must be reported via PAYE settlement agreement or it becomes a benefit-in-kind on the employee's tax code.
