Can I Write Off a Car Purchase for DoorDash?

Yes, you can write off a car purchase for DoorDash, but only the share tied to business use, and almost always through depreciation spread across several years rather than a single lump-sum deduction. The write-off is available only if you choose the actual expenses method for your vehicle, and for most standard cars the IRS “luxury automobile” caps limit how much of the purchase price you can deduct in year one.

You Have to Pick Actual Expenses, Not Standard Mileage

The IRS gives self-employed drivers two ways to deduct vehicle costs, and you choose one.¹ Only one of them lets you write off the purchase price.

The standard mileage rate is 72.5 cents per business mile for 2026.² That single per-mile figure already bakes in depreciation along with gas, insurance, and repairs, so there is no separate deduction for the car you bought. Multiply business miles by 72.5 cents and that’s your number.

The actual expenses method is what unlocks a purchase write-off. You track every vehicle cost for the year — gas, oil, tires, insurance, repairs, registration, and depreciation — and multiply the total by your business-use percentage.¹ The depreciation piece is how the car’s cost enters the deduction.

There is a timing trap. If you want the option to use the standard mileage rate on this vehicle in any future year, you have to choose it in the first year the car is available for business use. Start with actual expenses, and you’re locked in. Start with standard mileage and switch later, and your depreciation is limited to slower straight-line for the car’s remaining life, with no access to Section 179 or bonus depreciation.³

Figuring Your Business-Use Percentage

Your deduction rides on one number: the share of the car’s use that qualifies as business. Divide business miles by total miles for the year. Drive 20,000 miles total with 12,000 for deliveries, and business use is 60 percent. That percentage caps every vehicle deduction you claim, including depreciation on the purchase.

Business miles include driving between restaurants and drop-offs, moving between deliveries, and repositioning while the app searches for orders. Personal errands don’t count.

The commuting rule catches a lot of drivers. Without a qualifying home office serving as your principal place of business, the drive from home to your first pickup and back from your last drop-off is commuting, and commuting miles are never deductible.³ With a qualifying home office, those trips can count from mile one.

The 50 Percent Threshold Matters

To use Section 179 or bonus depreciation on the purchase, your business use has to exceed 50 percent for the year. Fall to 50 percent or below and you’re stuck with straight-line depreciation. Fall below the threshold in a later year before the car is fully depreciated, and the IRS makes you recapture part of the accelerated deductions you already claimed, reporting them as income for that year.⁴ If your car sits close to the line, track miles carefully.

How the Purchase Actually Gets Deducted

You recover the cost of a business vehicle through depreciation. The car is “placed in service” on the first day it is available for delivery work, whether or not you complete an order that day.³ Three depreciation methods can apply, sometimes stacked in the same year.

Section 179 Expensing

Section 179 lets you deduct part or all of the purchase price in the first year rather than spreading it out.⁵ For a standard passenger car, the total first-year write-off is capped by the luxury-auto limits described below, no matter how much you paid.

Bonus Depreciation

100 percent bonus depreciation is back for qualifying property acquired and placed in service after January 19, 2025. In principle that means writing off the full business share in year one. For a standard car, the luxury-auto caps still control the actual dollar amount. Bonus depreciation matters most for heavier vehicles that escape those caps.

Regular MACRS Depreciation

Whatever the first-year methods don’t cover gets spread over a five-year recovery period under the Modified Accelerated Cost Recovery System. Each year you deduct a percentage of the remaining basis, then multiply by that year’s business-use percentage.

The Luxury Automobile Cap on Standard Cars

The label is misleading. The “luxury automobile” limits apply to any passenger vehicle with an unloaded gross vehicle weight of 6,000 pounds or less, which covers the sedans and compact SUVs most DoorDash drivers use. For vehicles placed in service in 2025, the first-year cap was $20,200 with bonus depreciation and $12,200 without.⁴ The 2026 figures are expected to be slightly higher for inflation. And the cap is scaled by business use: at 70 percent business use, multiply the cap by 0.70 to find your actual maximum.

Heavier SUVs and Trucks Are Treated Differently

SUVs with a gross vehicle weight rating between 6,001 and 14,000 pounds are subject to a separate Section 179 cap, $31,300 for 2025 with a small inflation adjustment expected for 2026. Pickup trucks and vans above 6,000 pounds that aren’t designed primarily to carry passengers can qualify for the full Section 179 limit, which was $2,500,000 for 2025.⁴ These are the vehicles where bonus depreciation on top of Section 179 can actually zero out a large chunk of the purchase price in year one.

Other Vehicle Costs You Can Add

Under the actual expenses method, the purchase-price deduction sits alongside the running costs of the car, each prorated by business use.

Car loan interest, if you financed the purchase.
Auto insurance premiums.
Repairs and maintenance, including oil changes, tires, and brake work.
Annual registration and license fees.
Parking fees and tolls paid during deliveries, which are deductible on top of either method.¹

If you chose the standard mileage rate instead, most of these are already inside the per-mile figure and can’t be deducted separately. Parking and tolls are the exception.

The Deduction Also Cuts Your Self-Employment Tax

DoorDash pay is subject to self-employment tax on top of income tax, so every dollar you shave off Schedule C profit reduces both. The self-employment tax rate for 2026 is 15.3 percent on net earnings: 12.4 percent for Social Security on earnings up to $184,500, and 2.9 percent for Medicare.⁶ A $5,000 vehicle deduction saves roughly $765 in self-employment tax alone, before any income tax savings.

You also deduct the employer-equivalent half of your self-employment tax when calculating adjusted gross income, which trims income tax further.⁷

Records the IRS Expects

Without documentation, the deduction can be disallowed in an audit. Keep:

A mileage log with each trip’s date, starting point, destination, business purpose, and miles. A phone app that logs trips automatically satisfies this and is easier than paper.
Your year-end business-use calculation: business miles divided by total miles.
Purchase records, including the sales contract, loan agreement, and the date the car was placed in service.
Receipts for every vehicle expense you claim under actual expenses.

Keep these records for at least three years from the date you file.⁸ Overstating deductions due to negligence or inadequate records can trigger an accuracy-related penalty of 20 percent of the underpaid tax.⁹

Where It Goes on Your Return

Vehicle expenses go on Schedule C (Form 1040) with the rest of your DoorDash income and expenses.¹⁰ In the year you first depreciate the car or claim a Section 179 deduction, you also file Form 4562, and the depreciation amount from that form flows to the expenses section of Schedule C.¹¹

DoorDash doesn’t withhold, so you’re generally expected to make quarterly estimated payments on Form 1040-ES. The 2026 due dates are April 15, June 15, September 15, and January 15, 2027. You can skip that last payment if you file your 2026 return by February 1, 2027, and pay the balance with it.¹² You generally avoid an underpayment penalty if you owe less than $1,000 at filing, or if you paid at least 90 percent of the current year’s tax or 100 percent of the prior year’s (110 percent if your prior-year AGI exceeded $150,000).¹³

One Boundary if You’re Eyeing an EV

Buying an electric or plug-in hybrid still qualifies for the same depreciation rules as any other vehicle. But the federal clean vehicle tax credits — the New Clean Vehicle Credit, Previously-Owned Clean Vehicle Credit, and Qualified Commercial Clean Vehicle Credit — are not available for vehicles acquired after September 30, 2025.¹⁴ The credit of up to $7,500 on a new EV that many drivers still hear referenced doesn’t apply to a purchase made now.
