Minnesota → Michigan · Interstate 94 / Interstate 35W
The long-haul return between Minneapolis, Minnesota, and Detroit, Michigan — another 1030 km (640 miles) along Interstate 94 / Interstate 35W — closes a journey that hardly fits inside a single business day. Reserve another 9h 49m on the schedule and consider a second overnight if departure happens at the close of business hours. Anyone driving back from Minneapolis (the largest city in Minnesota and core of the Twin Cities metropolitan area) often pulls into Detroit (the Motor City and historic capital of the American auto industry) over the weekend. Incremental fuel adds $86.11 (93.6 liters / 24.7 gallons). Return reimbursement reaches $442.90 at the $0.43/km tariff. Reconcile outbound and return inside a single Clara PDF, with hotels itemized as separate line items, so finance can reimburse the full bundle in one batch. Priority processing happens when all supporting documents (fuel invoice, toll receipt, hotel folio, meal receipts) sit attached in chronological order and identified by the originating project number. For trips longer than three days, the finance department may also require an executive visit summary attached, describing objectives achieved, agreed next steps, and the commercial indicators generated. For the US professional driving the 1030 km (640 mi) between Minneapolis and Detroit, reimbursement of $442.90 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 Minneapolis→Detroit corridor must show date, business purpose, and odometer readings.
