DoorDash Deductions: The Records That Hold Up in an Audit
Claiming a deduction takes one line on Schedule C. Keeping it takes a record. Audits of gig drivers almost never argue that mileage is deductible — they argue that the driver can't prove the miles. Here's what proof looks like for each Dasher write-off, and how to build it without turning bookkeeping into a second job. Run your numbers in the [DoorDash deductions calculator](https://gigmytax.com/calculators/doordash-deductions) once the records are in place.
The rule behind every gig deduction
An expense has to be ordinary and necessary for the work, and you have to be able to show the amount, the date and the business purpose. Vehicle expenses carry a stricter standard: the IRS wants a log kept at or near the time of driving, not a spreadsheet built the week before filing.
What a defensible mileage log contains
Four columns: date, starting and ending odometer or total miles, destination, and business purpose. An automatic tracking app satisfies this if you keep the exported history. Screenshots of the DoorDash app alone usually don't, because they omit the driving between orders and to your starting zone.
Record the year-start odometer
One photo of the dashboard on January 1 and another on December 31 establishes total miles for the year, which is what makes a business-use percentage credible.
Phone: proving the business percentage
You deduct the business share of the plan, not the whole bill. Pick a defensible percentage from real usage — hours online divided by waking hours is a reasonable basis — write down how you calculated it, and keep the monthly statements. A 60% claim with a written basis survives; a 100% claim on a personal phone rarely does.
Gear, bags and supplies
Insulated bags, drink carriers, phone mounts, chargers, car cleaning and floor mats are deductible in full when bought for dashing. Card statements prove payment; the receipt proves what was bought. Save the receipt for anything above about $75, and photograph paper ones before the ink fades.
Tolls, parking and the fees people forget
Tolls and parking during deliveries are deductible on top of the standard mileage rate — they're not baked into the $0.70. Parking tickets never are. Toll transponder statements are ideal records because they timestamp each crossing.
Mixed-use items and the honest split
A dash cam used on personal drives, a car wash before a family trip, a phone plan shared with a spouse — split them by actual use and note the split. Auditors respond far better to a documented 70/30 estimate than to a round 100%.
A ten-minute weekly routine
Sunday night: export the week's mileage from your tracker, photograph any receipts into one folder, and log the totals in a single sheet with columns for miles, phone, gear, tolls and other. Twelve minutes a week produces a year of records that reconstructs in seconds at filing time.
How long to keep everything
Three years from the filing date covers the normal audit window; six if income was substantially understated. Keep vehicle records for as long as you claim the car, since basis and business-use history matter if you ever switch to the actual expense method or sell the car.
Frequently asked questions
+Does the DoorDash app's mileage count as a log?
Only partly. It typically records delivery miles but not driving to your zone or between orders, so it understates the deduction and lacks the purpose detail a log needs.
+Do I need receipts for every small expense?
Keep receipts for anything over roughly $75 and card statements for the rest. For vehicle expenses, the contemporaneous log matters more than receipts.
+Can I reconstruct a mileage log after the fact?
You can reconstruct a reasonable estimate from delivery history and map data, but it's weaker evidence than a log kept as you drove. Start logging going forward the same day you notice the gap.
+What percentage of my phone bill can I deduct?
The share genuinely used for the work. Many Dashers land between 40% and 70%; whatever you claim, write down the method you used to reach it.
+Are parking tickets deductible?
No. Fines and penalties are never deductible, even when incurred during a delivery. Legitimate parking fees are.
