RN → BA · BR-101 / BR-304
The long-haul return between Natal, RN, and Feira de Santana, BA — another 1078 km (670 miles) along BR-101 / BR-304 — closes a journey that hardly fits inside a single business day. Reserve another 12h 41m on the schedule and consider a second overnight if departure happens at the close of business hours. Anyone driving back from Natal (the capital potiguar conhecida como "Cidade do Sol" do litoral nordestino) often pulls into Feira de Santana (the segunda maior cidade baiana e principal entroncamento rodoviário do Nordeste) over the weekend. Incremental fuel adds R$ 597,80 (98 liters / 25.9 gallons). Return reimbursement reaches R$ 1185,80 at the R$ 1,10/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 1078 km (670 mi) between Natal and Feira de Santana, reimbursement of R$ 1185,80 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 Natal→Feira de Santana corridor must show date, business purpose, and odometer readings.
