Veracruz → Puebla · Carretera Federal 140 Xalapa-Veracruz
Punching Tehuacán, Puebla, into the GPS for the trip back from Xalapa, Veracruz, the dashboard once again shows the 163 km (101 miles) separating the two cities along Carretera Federal 140 Xalapa-Veracruz and estimates 1h 49m to wrap up the return. Xalapa, the capital veracruzana y centro universitario de la Sierra Madre Oriental, fades in the rear window while the vehicle picks up the homeward path toward Tehuacán, the segunda ciudad poblana y polo avícola y embotellador del centro-sur. 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 329.12 to cover the same 13.6 liters (3.6 gallons) consumed on the way out. The return reimbursement reaches MXN 1059.50 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 163 km (101 mi) between Xalapa and Tehuacán, reimbursement of MXN 1059.50 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 Xalapa→Tehuacán run must be reported via PAYE settlement agreement or it becomes a benefit-in-kind on the employee's tax code.
