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 US professional driving the 163 km (101 mi) between Xalapa and Tehuacán, reimbursement of MXN 1059.50 stays non-taxable to the employee when the employer follows an accountable plan under Treas. Reg. §1.62-2 and reimburses at or below the IRS standard mileage rate. US employers generally reimburse at the IRS standard mileage rate so the payment stays non-taxable to the employee under Pub. 463. Keep the IRS-compliant expense report (Form 1040 Schedule C, line 9) alongside the fuel receipt from any EIA-tracked retail station network pump used along the leg; Internal Revenue Service (IRS) examiners pull contemporaneous mileage logs first when auditing Schedule C unreimbursed business expenses, and the Xalapa→Tehuacán corridor must show date, business purpose, and odometer readings.
