SP → SP · SP-330 (Anhanguera)
Driving back into Campinas, SP, after wrapping the agenda in Ribeirão Preto, SP, tends to invite quiet reflection on operational efficiency: 270 km (168 miles) along SP-330 (Anhanguera) and another 3h 11m behind the wheel, not counting reception time, lobby waiting, and the actual meeting. Anyone returning from the place known as the capital nacional do agronegócio sucroalcooleiro reconnects with Campinas — the segunda maior cidade do estado de São Paulo e polo de tecnologia — carrying the dual sensation of a job done and accumulated fatigue. To minimize tiredness, alternate music, a technical podcast and absolute silence each hour. Additional fuel spend on the return runs R$ 149,45 (24.5 liters / 6.5 gallons). Equivalent reimbursement totals R$ 297,00 at the R$ 1,10/km tariff. On the Clara receipt, log notes about active road work seen along the way — the operations group uses that data to refresh the route's standard time each quarter. For the US professional driving the 270 km (168 mi) between Ribeirão Preto and Campinas, reimbursement of R$ 297,00 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 Ribeirão Preto→Campinas corridor must show date, business purpose, and odometer readings.
