Tlaxcala → Puebla · Carretera Federal 117 Tlaxcala-Puebla
Wrapping up the trip, the homebound leg from Tlaxcala, Tlaxcala, back to Tehuacán, Puebla, layers another 163 km (101 miles) onto the odometer along Carretera Federal 117 Tlaxcala-Puebla and tacks on roughly 1h 49m to the cumulative day. Drivers leaving Tlaxcala, the capital tlaxcalteca y la entidad más pequeña en superficie del país, usually pull into Tehuacán, the segunda ciudad poblana y polo avícola y embotellador del centro-sur, with an empty calendar but an inbox of paperwork — toll receipts, fuel invoices, visit reports, and meeting minutes all need to be tagged inside the cab before they get tangled with other paper stacks at the office. Average fuel spend on the return holds near MXN 329.12 for the 13.6 liters (3.6 gallons) burned. Mileage reimbursement for the homeward stretch totals MXN 1059.50 at the MXN 6.50/km benchmark.

For the US professional driving the 163 km (101 mi) between Tlaxcala 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 Tlaxcala→Tehuacán corridor must show date, business purpose, and odometer readings.
