Mileage Deduction Guide for Gig Workers: What Actually Counts

Mileage is the largest deduction most gig workers will ever claim, and it is the one they are most likely to shortchange themselves on. A driver who works 20 hours a week can put 14,000 business miles on a car in a year without noticing. At 2026 rates that is more than $10,000 of deduction, which for many drivers is the difference between owing four figures in April and owing almost nothing.

The rules are not complicated. They are just specific, and 2026 added a wrinkle that most mileage calculators have not caught up with.

2026 Is a Two-Rate Year

The IRS set the 2026 business standard mileage rate at 72.5 cents per mile in Notice 2026-10, up 2.5 cents from 2025. Then fuel prices moved enough during the first half of the year that the agency made an off-cycle adjustment: for miles driven July 1 through Dec. 31, 2026, the rate is 76 cents.

Midyear changes are rare. The last one was 2022. They matter because the rate that applies is the rate in effect on the day you drove, not the rate in effect when you file. If you drive all year and apply 76 cents to everything, you have overstated your deduction. If you apply 72.5 cents to everything, you have quietly handed money back.

The practical consequence is that your mileage log now needs a July 1 line drawn through it. Total your business miles for each half of the year separately, multiply each by its own rate, then add. Most tracking apps handle the split automatically, but check yours before you file: some carried the January figure all year.

Which Miles Count

A business mile is one driven for your trade or business. A commuting mile, meaning the drive between your home and a regular place of work, is never deductible. For a gig driver with no fixed workplace, most of the day sits comfortably on the business side, but not all of it.

Here is one evening for a delivery driver working DoorDash and Instacart, leg by leg.

About Those First and Last Legs

The drive out to your starting area and the drive home at the end are the one truly contested part of gig mileage, and you will find confident advice in both directions online. The rule that governs it is Revenue Ruling 99-7: travel between your residence and a work location is commuting, unless your residence is the principal place of business for that trade. If you maintain a qualifying home office where you do your scheduling, bookkeeping and account management, trips from home to work locations in the same business are deductible. If you do not, those legs look like commuting.

Turning the app on before you leave the driveway is a popular workaround. It is also a weaker position than most drivers assume, because the question is the purpose of the trip rather than the state of an app. This is worth 20 minutes with a preparer if it is a meaningful number of miles for you. The four categories in the middle of the table are not contested by anyone, and they are where most of the missing money is.

Why the Platform Summary Undercounts You

Every major platform sends an annual summary with a mileage figure on it. Uber, Lyft, DoorDash and Instacart all do. That figure is a starting point and nothing more. Platforms generally track miles from the moment you accept an order to the moment you complete it. The waiting, the circling, the drive from one drop-off to the next pickup and the trip out to a busier zone are all invisible to them.

Drivers who compare a full personal log against the platform number often find the gap runs 20% to 40%. On 14,000 miles that gap is worth thousands of dollars of deduction. You are allowed to claim every business mile you can substantiate, not only the ones your platform happened to record, which is the whole argument for keeping your own log. If you work more than one app, this compounds: see our guide for gig workers for how the platforms differ.

What the Log Has to Show

The law requires you to substantiate vehicle expenses with adequate records or with evidence sufficient to support your own statement. In practice a mileage record needs four things for each trip or each day: the date, the number of business miles, the destination or general area and the business purpose. You also need your odometer reading at the start and end of the year, because the deduction depends on what share of total driving was business.

Contemporaneous beats reconstructed. A log built during the year carries far more weight than one assembled in April from bank statements and memory, and the difference shows up immediately in an examination. Apps such as Stride, Everlance, MileIQ and Gridwise run in the background and classify trips with a swipe. A notebook in the glovebox and a monthly transfer into a spreadsheet works too, and costs nothing. What does not work is estimating a round number at filing time.

What the Deduction Is Actually Worth

Mileage reduces net profit on Schedule C, which means it reduces self-employment tax and income tax at the same time. That double effect is why vehicle deductions are worth more per dollar to a gig worker than retirement contributions, which do nothing for self-employment tax at all.

Standard Rate or Actual Expenses

The standard mileage rate is one of two methods. The other is actual expenses: add up what the car really cost you to run, then deduct the business-use percentage of it. Gas, insurance, repairs, tires, registration, licenses and depreciation or lease payments all go in the pot.

Marisol drove 18,205 total miles in 2026, 14,200 of them for work, so her business-use percentage is 78%. Here is the same year figured both ways.

Line item	Standard mileage	Actual expenses
Gas	Included in the rate	$3,420 × 78% = $2,668
Insurance		$1,860 × 78% = $1,451
Repairs, maintenance, tires		$1,240 × 78% = $967
Registration and fees		$210 × 78% = $164
Depreciation	Baked in at 35 cents per mile	$19,500 × 78% × 20% first-year MACRS = $3,042
Parking and tolls	Deductible on top	Deductible on top
Total deduction	$10,554	$8,291

The standard rate wins by $2,263 here, which is the usual result for a high-mileage driver in a reasonably economical car. Actual expenses tend to win in the opposite case: an expensive or thirsty vehicle, heavy repair bills, low annual mileage, or a first year with a large depreciation deduction available.

Two Rules That Decide It for You

The choice is narrower than it looks, because of a pair of restrictions in Topic no. 510.

First, if you want the option of using the standard mileage rate for a car you own, you have to choose it in the first year that car is available for business use. Miss that year and the door is shut for the life of the vehicle. Choose it in year one and you can switch between methods in later years, which is the flexible position and the reason many preparers default new gig drivers to the standard rate.

Second, the standard rate is off the table permanently for any car on which you claimed a Section 179 deduction, bonus depreciation or MACRS depreciation. That is the trap in the actual-expense method. A large first-year write-off feels like a win, and it commits you to tracking every receipt for gas, oil and repairs for as long as you own the car. You also cannot use the standard rate if you run five or more vehicles at once.

Parking fees and tolls tied to business driving are deductible under either method, on top of whatever the method itself produces. Speeding tickets are not.

Salvaging a Thin 2026 Log

If you have been driving all year without tracking, the next three months are still recoverable. Photograph your odometer now and again on New Year's Eve so you have a defensible year-end reading. Download every platform's trip history while it is still available, since some purge it after a few months. Reconstruct what you can from order timestamps and delivery addresses, label it honestly as an estimate and start a real log from today forward.

A reconstruction is worth less than a contemporaneous log and more than nothing. The point of doing it in September rather than April is that you still have three months of real records ahead of you, and a partial year of good documentation makes the estimated portion look like an honest gap rather than a guess covering the whole return.

Then Rerun the Number

Recalculate once the log is current. A mileage deduction that grew by several thousand dollars changes what you owe in January, and it may change whether you need to send a Q4 estimated payment at all. Our quarterly tax guide walks through that recalculation, and the gig worker pages cover how each platform reports the income side.
