North Carolina Mileage and Vehicle Tax Records (2026): 85% Depreciation Add-Back, TNC Permits and Driverless Cars
General information, not tax or legal advice. Talk to your tax preparer or attorney about your situation.
North Carolina starts from federal adjusted gross income, so a self-employed driver's federal mileage deduction carries over, but North Carolina adds back 85% of federal bonus depreciation, and 85% of the amount by which your federal Section 179 deduction exceeds what North Carolina's $25,000/$200,000 limits allow, then lets you deduct 20% of each add-back a year for five years. Rideshare companies need DMV permits, and fully autonomous cars may run driverless.
North Carolina's main vehicle adjustment is for depreciation, and it carries forward for five years. This guide covers what the North Carolina Department of Revenue (NCDOR) and the General Statutes say as of October 16, 2026.
The federal baseline every North Carolina driver starts from
Most vehicle deductions begin on your federal return. If you're self-employed, you can generally use the standard mileage rate or actual expenses for the business share of your car (IRS Topic 510). For 2026 the business rate is 72.5¢ per mile for January 1 to June 30 (IR-2025-128 / Notice 2026-10) and 76¢ per mile for July 1 to December 31 (IR-2026-29 / Announcement 2026-11) (IRS standard mileage rates). EVs use the same rates; see the 2026 EV mileage rate guide. Most employees can't deduct unreimbursed car expenses federally (Topic 510). IRS Publication 463 asks for each business trip's miles, date, destination and purpose, plus total miles. Commuting stays personal (commuting vs business miles).
How North Carolina treats vehicle deductions
The 2025 D-401 instructions start Form D-400 with federal adjusted gross income and set the 2025 rate at 4.25%. A Schedule C vehicle deduction is already in federal AGI. North Carolina's itemized deductions are its own list on D-400 Schedule A, and the 2025 instructions don't include unreimbursed employee business expenses.
Bonus depreciation: 85% added back
The 2025 instructions say North Carolina didn't adopt bonus depreciation under IRC 168(k) or 168(n) for property placed in service in 2025. You add back 85% of the bonus depreciation on your federal return (Schedule S, line 3). Then you deduct 20% of that add-back in each of the first five years starting in 2026.
Section 179: North Carolina limits
North Carolina didn't conform to the increased federal Section 179 limits for 2025. Its limits are $25,000 and $200,000. You add back 85% of the difference between the federal deduction and the deduction under North Carolina limits (line 4), then deduct 20% of it in each of the next five years. See robotaxi fleet depreciation and Section 179.
Rideshare (TNC) rules in North Carolina
Under G.S. Chapter 20, Article 10A, a TNC needs a permit from the Division of Motor Vehicles, with a $5,000 application fee and $5,000 annual renewal (G.S. 20-280.3). Fares must be paid electronically through the app, with no cash, and the rider gets a receipt showing start and end, time, distance and fare (G.S. 20-280.2). Insurance must cover 50/100/25 liability while you're logged on and $1 million during a ride (G.S. 20-280.4). G.S. 20-280.8 creates a rebuttable presumption that drivers are independent contractors. G.S. 20-280.10 bars local TNC fees and licenses, though airports may charge reasonable fees (G.S. 20-280.9). See which rideshare miles count.
Robotaxis and autonomous vehicles in North Carolina
G.S. 20-401 (2017) lets a person operate a fully autonomous vehicle that can comply with state traffic laws and federal safety standards, can reach a minimal risk condition, is insured and is registered as a fully autonomous vehicle. The operator needn't hold a driver's license while the system is engaged, and the registered owner is responsible for moving violations. A parent may not let a child under 12 ride unsupervised by someone 18 or older. Local governments can't regulate these vehicles separately. For fleet records, see robotaxi fleet tax basics.
What to keep in your North Carolina records
- Each business trip's date, start, destination, purpose and miles, plus total miles for the year (Pub 463); a weekly log counts as timely kept.
- Separate Business, Commute and Personal totals for Form 4562 Part V.
- Keep records until the period of limitations runs out, generally 3 years federally (IRS); ask your preparer about the state period.
- If you claimed bonus depreciation or Section 179 federally: the amounts and years, since the 85% add-back is deducted 20% a year for five years.
- For rideshare: keep the electronic receipts and annual summaries from each platform.
For the full list of log fields, see what the IRS asks you to record.
Example: 1,000 hypothetical business miles driven in September 2026 × 76¢ (IR-2026-29) = $760 at the federal standard rate. Miles driven in March 2026 would use 72.5¢ (IR-2025-128) instead, so keep each trip's date. Estimates, not tax advice.
One log for both returns
A North Carolina return doesn't call for a second mileage log; your preparer works from the same business, commuting and personal miles. CyberDeduct builds a mileage log around IRS Pub 463 from your Tesla's own trip and odometer data (Model S, 3, X, Y and Cybertruck). You connect your Tesla account once through Tesla's standard account sign-in (OAuth); CyberDeduct never sees or stores your password. Home/work rules and route templates label most trips Business, Commute or Personal; you tap to change any label and confirm the purpose. The dashboard shows your business-use percentage and warns you on the 28th if you're under 50%. You export a PDF or CSV log plus a Form 4562 Part V worksheet for your preparer. See how the log is built or see plans.
