Florida → Alabama · Interstate 95 / Interstate 10
Before turning the key for Birmingham, Alabama, on the homeward run from Jacksonville, Florida, do a quick inventory sweep of onboard equipment: proposal binder, undelivered promotional items, and visitor badge should each go into a separate compartment so nothing slides into the footwell during a sharp brake. Interstate 95 / Interstate 10 accepts the 710 km (441 miles) of the return in roughly 6h 46m. Pulling out of Jacksonville (the largest US city by area in the contiguous states and a major Atlantic naval port), the road eventually puts the driver back in front of the urban skyline of Birmingham (the largest city in Alabama and former steel-industry capital of the Deep South). Refueling sits near $59.34 for the same 64.5 liters (17.0 gallons) at the EIA national average benchmark. Return reimbursement, calculated against $0.43/km, returns $305.30 into the driver's wallet. Snap the closing odometer with the phone camera and attach it directly to the Clara receipt — internal controls accept photographic evidence without a supplementary spreadsheet. For the US professional driving the 710 km (441 mi) between Jacksonville and Birmingham, reimbursement of $305.30 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 Jacksonville→Birmingham corridor must show date, business purpose, and odometer readings.
