North Carolina has roughly 7 million licensed drivers covering 53,819 square miles, divided geographically among the coastal Atlantic plain, the Piedmont (Charlotte, Greensboro, Winston-Salem, Raleigh, Durham, Chapel Hill, Fayetteville), and the western mountain region (Asheville, Boone, Hendersonville). The Research Triangle Park (RTP) anchors one of the densest biotech and pharmaceutical clusters in the country, with major employers including Cisco, IBM, GlaxoSmithKline, Biogen, BioMarin, Eli Lilly, Fidelity, and roughly 300 other firms. Pharmaceutical and medical-device sales reps serving the RTP area, the UNC Health system, the Duke University Health System, the Wake Forest Baptist Health system, the Atrium Health network, and the Novant Health network routinely log 30,000 to 45,000 business miles per year on I-40, I-85, I-95, I-77, I-26, I-73, I-74, I-440 (Raleigh Beltline), I-485 (Charlotte Outer Loop), I-840 (Greensboro Loop), and the future Triangle Expressway extensions. Banking professionals serving Bank of America, Truist, and Wells Fargo's Charlotte operations cover regional mileage between Charlotte, Atlanta, Nashville, Richmond, and Columbia. Manufacturing-sector field engineers serving the High Point furniture industry, the Volvo Trucks plant in Pulaski, and the new Toyota battery plant in Liberty cover Piedmont mileage on I-40, I-85, and US 421. Agricultural extension agents covering the eastern Coastal Plain (Sampson, Duplin, Wayne, Wilson, Pitt, Greene, Lenoir, Jones counties) for the hog and poultry industries log significant rural mileage on I-95, US 70, US 64, US 17, and US 117. The North Carolina Department of Transportation (NCDOT) maintains over 80,000 miles of state highway, the second-largest state-maintained highway system in the country (only Texas is larger). The North Carolina Turnpike Authority operates the Triangle Expressway (NC 540), the Monroe Expressway (US 74 Bypass), and is constructing the Complete 540 extension; tolls on these facilities are paid via NC Quick Pass transponder. Hurricane-driven evacuations on I-40 west, I-26 west, US 70 west, and US 17 north / south are significant mileage drivers in the August-to-November window. The IRS standard mileage rate of 70 cents per mile (2025) governs federal income tax treatment.

North Carolina does not have a state statute requiring private-sector employers to reimburse business mileage at the IRS rate. The North Carolina Wage and Hour Act (N.C. Gen. Stat. Section 95-25.1 et seq.) requires payment of promised wages and reimbursements but does not specify a mileage rate. Most private employers default to the IRS standard mileage rate of 70 cents per mile (2025) because it is the simplest tax-free arrangement under IRC Section 62(c). State of North Carolina employees follow the Office of State Budget and Management (OSBM) Travel Policy under the State Budget Manual, Section 5, which currently sets the personal vehicle mileage rate at the federal IRS rate (70 cents per mile in 2025) when no state vehicle is reasonably available. NC Quick Pass tolls on the Triangle Expressway (NC 540) and the Monroe Expressway (US 74 Bypass) are reimbursable separately from mileage; account statements provide acceptable documentation. Field employees in pharmaceutical, medical-device, home-health, and biotech sectors operating across the Research Triangle, Charlotte, Triad, and Asheville markets should retain mileage logs for at least three years for IRS purposes (Treasury Regulation 1.274-5) and two years for North Carolina wage-claim limitation purposes (N.C. Gen. Stat. Section 95-25.22). Best-practice records include date, business purpose, starting odometer, ending odometer, and origin and destination, supplemented by NC Quick Pass statements, parking receipts, and fuel receipts when documenting actual costs. Pharmaceutical employers operating across the entire I-40 / I-85 corridor frequently deploy Fixed and Variable Rate (FAVR) programs approved under Revenue Procedure 2019-46 to reflect the cost differential between intown Charlotte and Raleigh and the rural eastern and western counties. Hurricane-driven evacuations on I-40 west, I-26 west, US 70 west, and US 17 are reimbursable as business-necessary deviations when properly documented with NCDOT 511 alerts. North Carolina's relatively moderate gasoline prices and insurance costs mean the IRS rate is generally adequate for most field employees, with the exception of those driving older vehicles or covering significant rural mileage where the per-mile depreciation rate runs higher.
