Mileage Deduction Rules 2026: Every IRS Requirement in One Place

The mileage deduction is the single largest write-off for most gig workers and 1099 contractors — but the IRS has strict rules on which miles qualify, how you document them, and which method you can use. Here is every 2026 rule in one place. Run your own numbers in our [business mileage deduction calculator](https://gigmytax.com/calculators/business-mileage-deduction).

The 2026 IRS standard mileage rate

For 2026 the IRS standard business mileage rate is **70¢ per mile**. Medical/moving is $0.21/mi and charity is $0.14/mi (set by statute). The business rate covers gas, oil, insurance, maintenance, tires, registration, and depreciation in one flat number — you cannot deduct those costs separately on top of the standard rate.

Rule 1 — the mile must be for business

Only miles driven with an ordinary and necessary business purpose qualify. For gig workers that means: from the moment you accept a delivery or ride until drop-off, driving between stops while online, driving to a hot zone once you're logged in, and business errands like fuel stops or car washes during a shift. Personal errands mixed in during a shift do not.

Rule 2 — commuting is NEVER deductible

The IRS treats the first drive from home to your first business stop, and the last drive home from your last business stop, as personal commuting — even for full-time gig workers. Exception: if you have a qualifying home office that is your principal place of business (Schedule C, Form 8829), the drive from home to the first job counts because your commute is effectively zero.

Rule 3 — pick a method in year one

You must choose **standard mileage** OR **actual expenses** in the first year you use a vehicle for business. If you elect actual expenses in year one, you can never switch to standard mileage for that vehicle. If you start with standard mileage, you can switch to actual in later years (straight-line depreciation only). Always start with standard mileage unless you drive a heavy vehicle (>6,000 lb GVWR eligible for Section 179).

Rule 4 — contemporaneous recordkeeping

The IRS requires a **contemporaneous log** — created at or near the time of each trip. Reconstructing a year of miles in April from bank statements is the #1 audit trigger for 1099 filers. Each entry needs date, business purpose, starting/ending odometer or distance, and destination. Use Stride, MileIQ, Everlance, or Hurdlr — GPS apps satisfy the contemporaneous rule automatically.

Rule 5 — the four data points every log must contain

Publication 463 is explicit: (1) date of trip, (2) business purpose, (3) miles driven, and (4) destination or starting/ending odometer. Missing any one of the four can invalidate an entire year of deductions in an audit.

Rule 6 — tolls, parking, and interest stack on top

Even under the standard mileage method you can still deduct business tolls, business parking, and the business-use % of car loan interest and state property tax on the vehicle. What you cannot double-deduct is gas, insurance, maintenance, or depreciation — those are baked into the 70¢.

Rule 7 — leased vehicles are locked to standard mileage

If you use the standard mileage rate on a leased vehicle in year one, you must use it for the entire lease term (including renewals). You also cannot claim Section 179 or bonus depreciation on a leased vehicle.

Rule 8 — multi-app and simultaneous miles

If you drive for DoorDash and Uber Eats at the same time, you cannot double-count the same mile. Log it once, allocate as needed. IRS auditors specifically look for impossibly-high mile counts vs. actual vehicle wear (oil changes, service records).

Method comparison — when actual expenses beat 70¢

Actual expenses usually wins for (a) heavy SUVs/trucks with Section 179 in year one, (b) expensive EVs where depreciation dwarfs the flat rate, or (c) very high per-mile operating cost (frequent repairs, premium fuel). For a Prius or Corolla at 15,000 business miles/year, standard mileage almost always wins. Compare both in our [business mileage deduction calculator](https://gigmytax.com/calculators/business-mileage-deduction).

How mileage flows on your tax return

Total business miles × $0.70 goes on **Schedule C line 9 (Car and truck expenses)**. This reduces net profit, which reduces both federal income tax and 15.3% self-employment tax — meaning every mile is worth roughly 25–35¢ in actual tax savings for most gig workers.

Bottom line for 2026

Track every business mile with an app from January 1, keep the log for at least 3 years after filing (7 for depreciation), and start with standard mileage unless you drive a heavy vehicle. That single habit is worth $3,000–$10,000/year for full-time gig workers.

Frequently asked questions

+What is the 2026 IRS mileage deduction rate?

70¢ per business mile, $0.21 per medical/moving mile, and $0.14 per charity mile. The business rate is set by the IRS each December for the following calendar year.

+Can I deduct miles driven to my first delivery of the day?

Generally no — the drive from home to your first pickup is considered personal commuting. Exception: if you claim a qualifying home office as your principal place of business, the first drive becomes deductible because your commute is zero.

+Do I need to keep a mileage log if I use the standard rate?

Yes. The recordkeeping rule applies to both methods. A contemporaneous log with date, purpose, and miles is required by Publication 463 regardless of which method you use.

+Can I switch from standard mileage to actual expenses later?

Yes, if you started with standard mileage. But if you elected actual expenses in year one, you are locked into actual expenses for that vehicle's entire useful life.

+Are tolls and parking included in the 70¢ rate?

No. Business tolls and parking are separate deductions you claim on top of the standard mileage rate. Only vehicle operating costs (gas, oil, insurance, maintenance, depreciation) are baked into the flat rate.
