Which method gives a bigger deduction?

It depends on your costs relative to your business mileage. At typical figures — 8,000 of 12,000 miles and $6,000 of costs — the standard rate wins ($6,080 vs $4,000). High-cost, low-mileage vehicles flip the result. Run both in the calculator.

Can I switch between standard and actual expenses?

You can generally move from actual expenses to the standard mileage rate in a later year. Once you have used the standard rate for a vehicle, though, you must generally keep using it for that car — you cannot switch back to actual expenses for the same vehicle.

Do I need receipts for the standard mileage rate?

No — under the standard method your mileage log (date, miles, purpose, odometer) is the required record. Receipts are required only if you claim actual expenses.

Do rideshare and delivery miles count?

Yes. Miles driven with the app on — pickups, deliveries, and repositioning between jobs — are business miles on Schedule C. The commute to your first working zone generally does not count. Keep your own log; platform summaries often miss repositioning miles.

Mileage Deduction for the Self-Employed: Standard vs Actual

By Maya Ellison · Updated September 2026

If your car is part of how you earn — driving to client meetings, hauling tools to a job site, delivering orders, working rideshare shifts — mileage is very likely the largest single deduction on your Schedule C. A driver logging 20,000 business miles writes off more than $15,000 of income before any other car cost is counted. Yet two patterns destroy that value every filing season: drivers who take no mileage deduction at all because they never kept a log, and drivers who pick the method that sounds simpler instead of the one with the bigger number. This guide explains the two methods the IRS allows, works a realistic example, covers the 2026 rate and the records that survive an audit — then hands the arithmetic to our mileage deduction calculator.

The two methods

The IRS offers exactly two ways to turn business driving into a tax deduction. You choose one method per vehicle per year, you cannot deduct the same mile twice, and you can never claim both the mileage rate and actual expenses for the same trip.

Standard mileage method: deduction = business miles × IRS standard mileage rate

The standard rate is a fixed cents-per-mile figure — 76¢ for 2026 business driving — that bundles fuel, oil, repairs, tires, insurance, registration, and depreciation into one number. You multiply your business miles by the rate and you are done. No gas receipts, no repair invoices: the only record you must keep is your mileage log. For most self-employed drivers this is both the cheaper and the safer option.

Actual-expenses method: deduction = total annual car costs × business-use percentage

Business-use percentage = business miles ÷ total miles driven (all purposes, business plus personal).

Here you total every real cost of operating the car — fuel, insurance, repairs, tires, registration, depreciation (or lease payments), and business-related parking — then prorate that total by the share of the car's life spent on business work. It requires receipts for everything and more math, but it pulls ahead when the car is expensive to run relative to the miles driven: a financed late-model vehicle with a major repair bill, or a car with high insurance premiums and modest business mileage. Whichever method you evaluate, the comparison belongs in the calculator: run both, take the larger figure, and re-run the comparison each year as costs and rates change.

Worked example: 8,000 business miles

Take a freelancer who drove 12,000 miles in 2026, of which 8,000 were business miles — client visits, site trips, supply runs — and whose car cost $6,000 to operate that year (fuel, insurance, repairs, and depreciation combined).

Formula: standard deduction = business miles × rate; actual deduction = total car costs × business-use percentage.

Standard method: 8,000 business miles × $0.76 = $6,080 deduction
Actual method: $6,000 total costs × (8,000 ÷ 12,000) = $6,000 × 0.667 = $4,000 deduction

The standard rate wins by $2,080 — and asks for nothing beyond the mileage log, where the actual method would have demanded receipts for the entire $6,000. This outcome is common: the 76¢ rate embeds a depreciation assumption that is generous relative to an ordinary repair-and-fuel year. Actual expenses only overtake it when costs are high relative to mileage — say $9,000 in costs on the same 8,000 of 12,000 miles, where the actual method would deduct $6,000. The crossover point is different for every car, which is exactly why you should compute both before filing rather than defaulting to folklore.

One frame worth keeping straight: a deduction reduces taxable income, it does not arrive as a refund check. That $6,080 write-off, taxed at a typical combined Schedule C marginal rate, saves roughly $2,000–$2,500 in actual tax — still the largest single expense line most self-employed drivers will claim, and free to produce once the log exists.

Practitioner note: In practice, the $2,080 gap above understates the standard method's edge: the $6,080 needed only a mileage log, while the $4,000 demanded receipts for the entire $6,000 of costs. Price your own record-keeping honestly — if receipts take hours you will never spend, the "better on paper" method is the worse choice. The method you document beats the method you intend.

The 2026 rate — and mid-year changes

The IRS set the business standard mileage rate at 76 cents per mile for 2026, up from 70 cents in 2025, as published on its standard mileage rates page. The agency re-evaluates the rate annually largely from empirical cost data — largely depreciation, fuel, insurance, and repair trends — and it can (and does) adjust the rate mid-year when fuel prices move sharply. The 2022 tax year saw one mid-year revision, from 58.5 cents to 62.5 cents on July 1, which is why the rate you claim depends on when the miles were driven, not merely which return you are filing.

Year	Business standard mileage rate
2026	76¢ per mile
2025	70¢ per mile
2022	58.5¢ per mile, revised to 62.5¢ on July 1

Practical rules: keep the rate field in the calculator aligned with the IRS figure for the year you are modeling, check irs.gov before filing rather than trusting last year's number, and if a mid-year change hit your driving period, apply the old rate to miles driven before the change and the new rate afterward. A one-number assumption is fine for estimates; a filed return needs the dated rates.

Where this comparison goes wrong:

You reconstruct the log in April. Only contemporaneous records — date, miles, purpose, odometer — survive scrutiny; an annual total with no trips behind it is not a log.
You forget total miles. The actual method's percentage needs every mile, personal included — 8,000 business miles mean nothing until divided by 12,000.
You leave tolls and parking inside the rate. The 76¢ bundles operating costs, but business tolls and parking stay separately deductible.
You commute from home with no qualifying office. The first trip to your working area and the ride back are personal, however carefully logged.

Records you must keep

The IRS substantiation rules for car expenses — spelled out in Publication 463, Travel, Gift, and Car Expenses — require enough evidence to establish three things for every business trip:

Date of the trip.
Miles driven (a starting and ending odometer reading makes this airtight).
Business purpose — the client, the site, the delivery — not just "business use."

The log should be contemporaneous: recorded at or near the time of the trip, not reconstructed from memory the week before your appointment. A useful habit is to capture the odometer on the first and last trip of each year — those two readings bound every mileage figure you will ever need to defend. A dedicated mileage app, your platform's trip export plus a purpose column, or a plain spreadsheet all satisfy this — what fails is an annual total with no trips behind it. Under the standard method, the log is the entire paper trail. Under actual expenses, you additionally keep receipts for fuel, insurance, repairs, and proof of depreciation. Contractors who also track non-car costs will find the receipt side of this familiar from our freelance expense tracking guide; the mileage log is simply the vehicle-specific version of the same discipline.

Gig driver specifics: Uber, DoorDash, and delivery

Gig driving counts. Miles driven while the app is on and you are available for work — to the pickup, with the passenger, to the drop-off, between orders while repositioning — are business miles reported on Schedule C. The commute to your first zone and the ride home generally are not: the IRS treats the first trip of the day from your home base to your working area as personal unless you have a home office as your principal place of business. Platforms mail annual summaries, but those summaries typically show only on-app miles and miss the repositioning driving between trips — miles that are often deductible and that only your own log captures. For the fuller expense picture (phone costs, bags, insurance riders, and how deductions interact with self-employment tax), see the gig driver tax deductions checklist.

Run the numbers

The paired mileage deduction calculator defaults to the 2026 standard rate — enter your business miles, flip the method selector to actual expenses, enter your yearly car costs and total miles, and the tool shows each deduction side by side with the method note underneath. Use it once with your real log before you file, then again in January when the IRS posts the new year's rate. The whole comparison takes about thirty seconds; leaving it on the table costs thousands.
