Schedule C for Gig Drivers, Line by Line

GigOdo Team · Published July 10, 2026 · Every figure sourced to the IRS unless noted

Who files Schedule C - and do you need a 1099?

Every gig driver working as an independent contractor files Schedule C (Form 1040), "Profit or Loss From Business," with their tax return. No 1099 is required to file it, and no missing 1099 excuses you from filing: once net earnings from self-employment reach $400, you must file and pay self-employment tax, per IRS Tax Topic 554.

Missing forms are now the normal case. The 1099-K threshold is $20,000 and 200 transactions (IRS announcement IR-2025-107), so plenty of working drivers receive nothing at all in January. The IRS position doesn't change: every dollar of driving income is reportable, forms or no forms. Your own records are what fill in the gap.

One note on form years: the line numbers below come from the current Schedule C, the 2025 revision, which is the latest the IRS has published. The layout has been stable for years, but glance at the year printed on your copy when you file.

The header boxes: code, method, and the 1099 questions

Before Part I, Schedule C asks ten lettered questions, A through J. Four matter for a driver: your business description (box A), your business code (box B), your accounting method (box F - almost always cash), and whether you made payments that would require you to issue 1099s to others (box I - for a solo driver, generally No).

For box A, plain words work: "delivery driving" or "rideshare driving." For box B, the instructions' code chart gives delivery work 492000 (couriers & messengers) and rideshare 485300 (taxi, limousine, & ridesharing service). Run both? The instructions say to pick the code for the activity producing the largest share of your receipts. Box G, material participation, is Yes - you did the driving yourself.

The IRS requires a separate Schedule C for each business you own, but that means each distinct business, not each app. Most preparers treat all of your app driving as a single business on one Schedule C, with your platforms' income combined on line 1. A genuinely different sideline - freelance design, say - gets its own form.

Part I: your income lines

Line 1, gross receipts, carries everything you were paid for driving during the year: platform payouts, bonuses and incentives, and every tip, cash included, whether or not any form reports it. Lines 2 through 6 rarely apply to a driver with no returns and no inventory, so line 7, gross income, usually just equals line 1.

The trap is what "gross" means on your platform's paperwork. If your tax summary reports gross fares with commissions and fees subtracted afterward - Uber's model, covered in our Uber Eats tax guide - report the gross number on line 1 and deduct the fees on line 10. If your 1099 already reflects what actually hit your account, as is typical for Dashers (see the DoorDash tax guide), report that and deduct nothing extra. Reporting deposits while also deducting fees counts the same money twice.

Line 9: where the mileage deduction actually goes

The biggest number on most drivers' Schedule C belongs on line 9, "Car and truck expenses": your 2026 business miles times the IRS rate for the trip's date (72.5-76 cents in 2026), plus business parking fees and tolls. The Schedule C instructions say it directly: add your parking fees and tolls to the mileage amount and enter one total on line 9.

At the 2026 rate, 12,000 logged business miles put about $9,120 on line 9 before a single receipt. The same instructions draw the boundary just as clearly: if you use the standard mileage rate, "do not deduct depreciation, rent or lease payments, or your actual operating expenses." Gas, repairs, tires, oil changes, and car insurance are already inside the standard rate. Claiming them again on other lines is the classic double dip.

Part IV: the vehicle questions that back up line 9

Part IV, "Information on Your Vehicle" (lines 43 to 47), is where the IRS asks about the car behind your line 9 number. It is informational - no dollar amounts go here - but it is required when you claim car expenses on line 9 and aren't filing Form 4562, and two of its five questions are about your records.

Line 43 asks when you placed the vehicle in service for business. Line 44 splits the year's total miles three ways: business (44a), commuting (44b), and other (44c). Lines 45 and 46 ask about personal use and other household vehicles. Then the pointed pair: line 47a, "Do you have evidence to support your deduction?" and 47b, "If Yes, is the evidence written?"

You want both answers to be Yes, truthfully. Written evidence means the contemporaneous log IRS Publication 463 describes - date, miles, destination, and business purpose, recorded at or near the time of the trip. An automatic tracker like GigOdo produces exactly that record all year and totals lines 44a-44c for you, with a CPA-ready report pack at filing time.

The rest of Part II, line by driver line

Beyond line 9, a handful of Part II lines do real work for a driver: line 10 for platform commissions, line 22 for supplies, line 25 for the business share of your phone plan, and line 27b for everything else, itemized in Part V on page 2. Most of the other lines stay blank, and that is fine.

• Line 10, commissions and fees - platform commissions, but only when the income you reported on line 1 includes them.
• Line 15, insurance (other than health) - mostly not for drivers: car insurance, including a rideshare endorsement, is vehicle cost, and the standard mileage rate already covers it. Health insurance never goes here; it has its own deduction on Schedule 1.
• Line 17, legal and professional services - the business portion of tax prep fees is commonly deducted here.
• Line 22, supplies - hot bags, phone mounts, chargers, flashlights.
• Line 23, taxes and licenses - business license or registration fees for your gig work.
• Line 25, utilities - the business-use percentage of your cell plan is deductible; preparers commonly put it here or in Part V. Claiming 100% of a phone you also use personally is not defensible.
• Line 27b, other expenses - the total from Part V, line 48, where you list anything that fits nowhere else, like the business share of a roadside assistance plan.

Line 30: the home office line most drivers skip

Line 30 deducts business use of your home, and for most gig drivers the honest answer is zero. The space has to be used regularly and exclusively for the business, and a car-based business rarely clears that bar. If you genuinely qualify, the simplified method allows $5 per square foot, up to 300 square feet.

Some drivers chase this line hoping a qualifying home office converts the first and last drive of the day from commuting into business miles. The principal-place-of-business rules behind that are narrow and fact-specific - do not claim it without a tax professional's sign-off.

Line 31: the number that sets everything else in motion

Line 31, net profit, is Schedule C's bottom line: line 7 income minus line 28 expenses, minus any line 30 amount. The form itself tells you where it goes next: to Schedule 1 (Form 1040), line 3, where it joins your other income, and to Schedule SE, line 2, where self-employment tax is figured.

Self-employment tax runs 15.3% - 12.4% Social Security plus 2.9% Medicare - applied to 92.35% of your net earnings, and you deduct half of the SE tax itself on Schedule 1 (Topic 554). Line 31 also feeds the qualified business income deduction, generally up to 20% of qualified income for sole proprietors, which 2025's One Big Beautiful Bill Act made permanent. And it is the number your quarterly estimated payments are supposed to be tracking all year.

A worked example: 11,000 miles, $28,400 gross

Here is how the form adds up for a delivery driver who grossed $28,400 across apps in 2026 and logged 11,000 business miles plus $180 in parking and tolls. The dollar figures are illustrative, but the mechanics - and how much of the work line 9 does - are typical of real driver returns.

Illustrative example. Mileage rate per IRS Notice 2026-10; SE tax math per IRS Topic 554.

From there, Schedule SE applies 92.35% to the $19,790 (about $18,276) and taxes it at 15.3%: roughly $2,796 of self-employment tax, half of which ($1,398) comes back as a deduction on Schedule 1. Income tax then applies to the profit separately. Notice what the mileage log did: without those 11,000 documented miles, taxable profit would have been $7,975 higher.

The five misfilings preparers see most

The same handful of Schedule C mistakes shows up on driver returns every year. Most are less audit bait than money left on the table - or deductions claimed twice that will not survive a second look. Check your draft return against these five before you file.

1. Reporting deposits, not gross receipts. If your platform reports gross fares, line 1 gets the gross and line 10 gets the fees - not the net with fees deducted again.
2. Deducting gas and repairs on top of the mileage rate. The instructions forbid it; those costs are inside the standard rate.
3. Treating Part IV as the deduction. Lines 43-47 are questions about the car. The dollars go on line 9, or they go nowhere.
4. Claiming every mile. The first leg out from home and the last leg back are generally commuting - that is line 44b, not 44a, unless a qualifying home office changes the analysis.
5. Deducting personal costs at 100%. Your own lunch on shift is generally not deductible, and a phone you also use personally goes in at its business percentage, not the whole bill.

Bottom line

Schedule C is not a hard form for a driver - it is a form that rewards a year of good records. Line 1 wants everything you earned, line 9 wants every mile you can document, and lines 47a and 47b ask, in writing, whether you kept the log. Get those three right and the rest is arithmetic.
