Your odometer is a tax asset
Every business mile a gig driver turns in 2026 is worth 76 cents of deduction under the current IRS standard mileage rate — no receipts, no depreciation schedules, one multiplication. A DoorDash driver doing 200 business miles a week generates roughly $7,900 of annual deductions. At a 22% marginal bracket that's $1,738 of federal income tax erased, plus the self-employment tax shrinks too (the deduction lowers Schedule C net earnings, the base for the 15.3% SE tax).
How the math works
Deduction = business miles × $0.76 (July–Dec 2026 rate, IR-2026-29) Est. federal income-tax savings = deduction × your marginal bracket
Pick the bracket your last dollar falls in (not your effective rate). The calculator also shows the SE-tax side benefit: deduction × 92.35% × 15.3%.
Worked example
A rideshare driver logs 12,000 business miles in 2026 and sits in the 22% bracket:
| Step | Calculation | Result |
|---|---|---|
| Deduction | 12,000 × $0.76 | $9,120.00 |
| Income-tax savings | $9,120 × 22% | $2,006.40 |
| SE-tax base reduction | $9,120 × 92.35% × 15.3% | $1,288.61 |
| Combined estimated savings | $3,295.01 |
That $3,295 is real money — but only if the miles are logged. Which brings us to the unglamorous part.
The log is the deduction
The IRS requires a contemporaneous mileage log: date, miles, business purpose for each trip. Reconstructing "about 200 miles a week" at tax time is explicitly disallowed and collapses under audit. Mileage-tracker apps that log automatically satisfy this; a notebook in the glovebox does too, if you actually fill it in. Start the log the day you start driving — backdated logs are worse than no log because they look fabricated.
Standard mileage vs. actual expenses: when to switch
The standard rate wins for most gig drivers because it's simple and generous — 76¢ a mile usually exceeds what a fuel-efficient car actually costs per mile to run. Actual expenses (gas, insurance, repairs, plus depreciation, all prorated by your business-use percentage) can win if you drive an expensive vehicle with high insurance and repair bills. The catch is paperwork: every receipt, every year, plus a depreciation schedule — and once you claim accelerated depreciation on a vehicle, switching back to standard mileage gets restricted. Rule of thumb: if your car is ordinary and your records are thin, take the standard rate; if your car is expensive and your bookkeeping is disciplined, run both numbers for a year before committing. Either way, the mileage log requirement doesn't go away.
Watch the mid-year rate split
2026 is unusual: the IRS raised the rate mid-year (72.5¢ Jan–Jun → 76¢ Jul–Dec) after fuel prices spiked — the first mid-year change since 2022. This calculator uses 76¢ throughout and says so. If your miles skew heavily to the first half of the year, knock roughly 4.6% off the deduction for an honest blended figure (72.5 ÷ 76).
Data sources: IRS Notice 2026-10 (72.5¢ Jan–Jun 2026); IRS Announcement 2026-11 / IR-2026-29 (76¢ Jul–Dec 2026); IRS mileage-log recordkeeping requirements. Figures reflect the 2026 tax year. Estimates only, not tax advice — "estimates only, not tax advice."
Frequently asked questions
What is the IRS mileage rate for 2026?
The IRS raised it mid-year: 72.5¢ per mile for January–June 2026 (Notice 2026-10), then 76¢ per mile for July–December 2026 (Announcement 2026-11, IR-2026-29) after fuel prices spiked. This calculator uses the current 76¢ rate and notes the split — if most of your miles were early-year, your true blended deduction is slightly lower.
Standard mileage or actual expenses — which is better for gig drivers?
Standard mileage (miles × IRS rate) wins for most gig drivers: no receipts to hoard, one multiplication, and 76¢/mile usually beats real costs unless you drive a gas-guzzler with constant repairs. Actual expenses (gas + insurance + depreciation + repairs, prorated by business-use %) can win for expensive vehicles — but then you must track everything. You can switch methods year to year with restrictions, so run both numbers before committing.
What miles count as business miles for Uber or DoorDash?
Miles driven for business: en route to pickups, during trips, and between consecutive gigs (e.g., driving from one delivery drop-off toward the next ping). Commuting from home to your first gig area and back is generally not deductible. Deadhead miles between gigs usually are — which is why total business miles often surprise drivers.
What does the IRS require in a mileage log?
For each business trip: the date, the miles driven, and the business purpose/destination. The IRS explicitly rejects estimates made at tax time — 'about 200 miles a week' reconstructed in April won't survive an audit. A contemporaneous log (an app that tracks automatically counts) is the requirement, not a nice-to-have.
Does the mileage deduction reduce my self-employment tax too?
Yes — and that's the part people miss. The mileage deduction lowers your net self-employment earnings on Schedule C, which shrinks both your income tax AND your 15.3% self-employment tax base. A $9,120 deduction at a 22% bracket saves $2,006 in income tax plus about $1,287 in SE tax. This calculator shows the income-tax savings; the SE-tax bonus is extra.
Can W-2 employees deduct mileage?
Generally no. Since the 2018 tax changes, unreimbursed employee business expenses aren't deductible for W-2 workers through 2025, and the 2026 rules continue that treatment for most employees. The mileage deduction is a self-employed / 1099 benefit — one more line item for the W-2 vs 1099 comparison.
