CE → MA · BR-116 / BR-222
Tackling the 846 km (526 miles) that separate Fortaleza, CE, from São Luís, MA, in a single push demands long-haul planning: 9h 57m behind the wheel along BR-116 / BR-222 exceeds the safe ceiling on continuous driving. Schedule a midpoint overnight, driver swap (where applicable) and a mandatory pre-trip inspection. Pulling out of Fortaleza (the capital cearense e maior cidade do Nordeste em PIB) toward São Luís (the capital maranhense fundada por franceses e patrimônio histórico da UNESCO), total fuel use reaches 76.9 liters (20.3 gallons) of gasolina comum (about R$ 469,09), on top of consecutive tolls and a probable hotel night. Gross outbound reimbursement, against the mercado privado (faixa típica) schedule of R$ 1,10/km, lands at R$ 930,60. Capture lodging and meals in separate fields of the Clara receipt so they don't get tangled with the pure mileage calculation. The typical corporate policy authorizes a hotel per-diem up to a certain ceiling and meals with a limit per occurrence, amounts that must be substantiated with a fiscal invoice in the contributor's or the company's name. Confirm before the trip the prevailing ceiling per the internal HR table, and verify that the chosen hotel issues an invoice in the format the corporate fiscal system accepts, avoiding later disallowance of the amount. For the US professional driving the 846 km (526 mi) between Fortaleza and São Luís, reimbursement of R$ 930,60 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 Fortaleza→São Luís corridor must show date, business purpose, and odometer readings.
