Quintana Roo → Quintana Roo · Carretera Federal 307 Cancún-Tulum
Retracing the scenic corridor between Playa del Carmen, Quintana Roo, and Cancún, Quintana Roo, in reverse uncovers angles missed on the outbound run — afternoon-lit hillsides, overlooks that sit on the left now, calm beaches that were busy in the morning. It is the same 79 km (49 miles) and roughly 53m along Carretera Federal 307 Cancún-Tulum, only seen with fresh eyes. Playa del Carmen (the principal polo turístico de la Riviera Maya y puerto de embarque a Cozumel) slips behind, while Cancún (the destino turístico número uno del Caribe mexicano) welcomes the driver in the late afternoon. Fuel sits around MXN 159.72 for 6.6 liters (1.7 gallons). Return reimbursement totals MXN 513.50 at the MXN 6.50/km tariff. On the Clara receipt, note the scenic corridor in the observations field to feed the internal catalog of business-tourism routes. Attach a photograph of the closing odometer alongside the exact arrival timestamp, particularly if the return crossed sunset — that detail helps the back office confirm hours-of-service when there is doubt about total time worked. To close the loop, update the corporate expense application with each scenic stop made along the way, even when no fiscal receipt was generated, so the operations log reflects the full traveled corridor. For the US professional driving the 79 km (49 mi) between Playa del Carmen and Cancún, reimbursement of MXN 513.50 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 Playa del Carmen→Cancún corridor must show date, business purpose, and odometer readings.
