Schedule C Vehicle Expenses: 2026 Walkthrough

The hardest part of doing your own taxes as a driver isn’t the math. It’s knowing which line gets which number. You read a TurboTax help article telling you to “put your mileage on Schedule C.” Great. Schedule C has 32 numbered lines, four parts of vehicle questions, and a depreciation form that references three more parts of itself. Where, exactly, does $13,050 of mileage go?

This guide answers that question line by line for the 2025 Schedule C (the form you file in 2026) and the 2026 standard mileage rate of 72.5¢ per mile set by IRS Notice 2026-10. We walk the form in order. We name every line. We show you the new Line 27a/27b split that surprised preparers this filing season. We finish with a full worked example for a real-looking multi-platform delivery driver — 22,000 business miles, three 1099-NECs, a home office, and a Schedule SE that translates the deduction into actual dollars in your pocket.

Key takeaways

• Vehicle expenses for self-employed drivers land on Schedule C, Line 9 (standard mileage or actual expenses combined) plus Part IV (the four-question vehicle disclosure).
• The 2026 standard mileage rate is 72.5¢/mile for business under Notice 2026-10. The depreciation portion baked in is 35¢/mile.
• Form 4562 Part V is required if you take actual expenses, §179, or bonus depreciation, or in the first year a vehicle is placed in service.
• Mileage cuts both federal income tax and self-employment tax — roughly 14.13¢ of SE-tax savings on every deductible dollar under the Social Security wage base.
• OBBBA (P.L. 119-21) changed three things drivers must know for 2026: 100% permanent bonus depreciation (§70301), the new Schedule 1-A “No Tax on Tips” deduction for qualifying rideshare and delivery tips (§70201), and the car loan interest deduction split between Schedule C Line 16b (business portion) and Schedule 1-A Part IV (personal portion) (§70203).
• The IRS doesn’t allow you to estimate vehicle expenses under Cohan v. Commissioner. §274(d) demands strict, contemporaneous records.

How Schedule C is structured — and where the vehicle stuff lives

Schedule C is the income tax return your sole-proprietor business files inside your personal 1040. It has a header, five parts, and a place for every dollar of business income and expense you had during the year. Vehicle expenses appear in two places on the form itself (Lines 9 and 13, plus Part IV), and they spill across a half-dozen other lines when you take actual expenses instead of mileage. Knowing the geography saves hours of confusion.

The header section (Boxes A through J)

Before the numbers, you describe the business. Box A is “Principal business or profession” — write something concrete like “Rideshare driver,” “Food delivery driver,” or “Mobile detailing.” Don’t write “self-employed.” Box A becomes part of the IRS’s matching against your 1099s.

Box B is the six-digit principal business activity code, and this matters more than most drivers realize because the IRS uses it for audit selection. The codes that fit most of our readers:

• 485300 — Taxi, limousine, and ridesharing service. This is the right code for Uber, Lyft, Via, and most rideshare work. The NAICS 2022 description explicitly includes ridesharing.
• 492000 — Couriers and messengers. This is the right code for DoorDash, Uber Eats, Instacart, Spark, Grubhub, Amazon Flex, Shipt, and similar last-mile delivery.
• 531210 — Offices of real estate agents and brokers. The code we walked through in our Mileage Tracking for Real Estate Agents guide.
• 541990 — All other professional, scientific, and technical services. A reasonable catch-all for many independent freelancers.
• 711510 — Independent artists, writers, and performers. Right for freelance journalists and creative freelancers.
• 811192 — Car washes (which NAICS defines to include mobile detailing).
• 811111 — General automotive repair (mobile mechanics).

Pick the code that best describes the majority of your gross receipts. If you do 80% rideshare and 20% DoorDash, use 485300. We dig into this more in our Uber & Lyft Driver Mileage Tax Guide and Delivery Driver Mileage Tax Guide.

Box C is your business name. If you operate under your legal name, leave it blank. Box D is your EIN, only if you applied for one — most sole-prop drivers don’t and leave it blank. Box E is your business address (your home address is fine if you don’t have a separate one). Box F asks accounting method; almost every driver picks (1) Cash. Box G asks whether you materially participated — yes, you drove the car. Box H flags a new business this year. Boxes I and J ask about 1099s you issued; most solo drivers answer “No” because they didn’t pay subcontractors.

Part I — Income (Lines 1–7)

Part I tells the IRS what your business took in. For a service driver who doesn’t sell inventory, the math is simple. Line 1 is gross receipts — the total across every 1099-K, 1099-NEC, and cash tip you received, before any platform fees, before any commissions, before anything is netted out. The trap drivers fall into here is reporting only their bank deposits: your Uber 1099-K shows gross fares, not net deposits. Use the gross number.

Lines 2 through 4 handle returns and cost of goods sold, neither relevant for service drivers, so they typically read zero. Line 5 equals Line 3 (gross profit). Line 6 is “other income” — fuel tax credits, state EV rebates that are taxable, gas tax refunds. Line 7 sums to gross income.

Under OBBBA §70432, the 1099-K threshold restored to $20,000 and 200 transactions (retroactive to 2022). Under §70433, the 1099-NEC threshold rose to $2,000 for payments made after 12/31/2025. Both changes mean drivers may receive fewer 1099s in 2026 — but you still owe tax on every dollar you earn. See our OBBBA Tax Changes for Self-Employed Drivers pillar.

Part II — Expenses (Lines 8–30)

Part II is where the deductions live, and there’s been a change for 2025 that catches preparers off guard. Line 27a is now “Energy efficient commercial buildings deduction (attach Form 7205)” — it used to be the general “Other expenses” line. Line 27b is the new home for “Other expenses (from line 48)” — the Part V catch-all. If you’re reading a 2023 guide that says “list your hot bag on 27a,” update it: that goes on 27b for 2025 forward.

The vehicle-specific lines you care about:

• Line 9 — Car and truck expenses. Where standard mileage OR the operating portion of actual expenses lands. Plus parking and tolls.
• Line 13 — Depreciation and §179. Where Form 4562 dumps your depreciation number if you take actual expenses or §179 a vehicle.
• Line 15 — Insurance. Commercial auto premiums under actual expenses; not used under standard mileage (insurance is baked into the rate).
• Line 16b — Other interest. Business-use portion of your vehicle loan interest. Allowed on top of the standard mileage rate.
• Line 20a — Rent or lease (vehicles). Where lease payments live under actual expenses.
• Line 23 — Taxes and licenses. Business-portion of personal property tax on the vehicle. Also allowed on top of standard mileage.
• Line 25 — Utilities. The business-use percentage of your cell phone bill — non-trivial for drivers who use a personal phone for platform apps.

Part III — Cost of goods sold (Lines 33–42)

You can skip this. COGS is for resellers and manufacturers who hold inventory. A driver buying hot bags for $50 doesn’t have COGS — that’s a Line 22 supply or a Part V “other expense.”

Part IV — Information on Your Vehicle (Lines 43–47)

This is the substantiation gate. If you take the standard mileage rate (Line 9) AND you don’t have to file Form 4562 for any other reason, Part IV is where you answer the four §274(d) substantiation questions. We walk these line by line below.

Part V — Other Expenses

Below Part IV sits Part V, a list. You write the category and the amount on each row, total on Line 48, and that total flows up to Schedule C Line 27b. We show what goes here for delivery vs. rideshare drivers in detail below.

Part II Line 9 — the standard mileage walkthrough

For most rideshare and delivery drivers, Line 9 contains a single number: business miles × the IRS standard rate. For 2026, that rate is 72.5¢/mile per Notice 2026-10, up from 70¢/mile in 2025.

What the 72.5¢ includes (and what it doesn’t)

The standard mileage rate is a bundled, IRS-blessed average. It includes depreciation (35¢/mile for 2026 — that’s the portion of the rate the IRS attributes to wearing the vehicle out), fuel, oil, lubrication, routine maintenance, repairs, tires, vehicle insurance, registration fees, and license fees.

It does not include four things you can still deduct on top:

1. Parking paid while doing business (not commuting). Goes on Line 9 alongside the per-mile amount.
2. Tolls paid during business driving. Same — Line 9.
3. The business-portion of vehicle loan interest. Goes on Schedule C Line 16b.
4. The business-portion of personal property tax on the vehicle. Goes on Line 23.

If you pay a $14.95/month FasTrak account fee, the fees portion may belong on Line 27b/Part V as a transponder service charge; the actual tolls go on Line 9.

The math

The structure is simple:

• Business miles × 72.5¢ = base deduction
• • Business parking
• • Business tolls
• = Schedule C Line 9 amount

The first-year election rule (and why it matters)

Under Rev. Proc. 2019-46, if you want the option to use standard mileage for a vehicle, you must elect it in the first year you place the vehicle in service for business. If you take actual expenses (specifically, MACRS depreciation, §179, or bonus depreciation) in year one, you’ve locked yourself out of standard mileage on that vehicle forever.

The reverse is more flexible: you can start on standard mileage and switch to actual later (with one catch — switching to actual forces you onto straight-line depreciation, not the faster MACRS double-declining-balance method, and the remaining basis is computed under §280F).

This decision matters enough that we built an entire pillar around it — Standard Mileage vs. Actual Expenses. For 90% of rideshare and delivery drivers, standard mileage wins — both on dollars and on simplicity.

The lease rule and the fleet rule

Two other Rev. Proc. 2019-46 rules trip drivers up.

Leased vehicles: if you use standard mileage in year one of the lease, you must use standard mileage for the entire lease term (including renewals). If you start on actual, you’re locked into actual for the life of the lease.

Five-or-more vehicles: if you operate five or more vehicles simultaneously in your business — a small fleet — you cannot use standard mileage, period. This is uncommon for sole proprietors but catches a few independent owner-operators with multiple cars on the road at once.

Common Line 9 mistakes

We see four recurring errors:

The first is netting fuel out of income. Drivers see “I spent $4,200 on gas” and try to subtract it from Line 1. Don’t. Income is income; deductions are deductions. Gas is already absorbed in your 72.5¢/mile rate under standard mileage.

The second is leaving parking and tolls off Line 9. They’re deductible on top of the rate. A driver paying $35/week in airport tolls leaves $1,800 on the table by forgetting.

The third is double-counting. You can’t claim 72.5¢/mile AND a separate fuel deduction. Pick one method per vehicle per year (with the first-year election rule above).

The fourth is misallocating between two cars. If you used two vehicles for the business during the year, Schedule C Part IV only has room for one. Drivers with multiple vehicles must file Form 4562, regardless of method.

Part IV — the four substantiation questions

If you take standard mileage on a single vehicle and don’t otherwise need Form 4562, you fill out Schedule C Part IV (Lines 43–47). These five questions exist because §274(d) imposes “strict substantiation” on listed property — and your car is listed property. Get the questions wrong and you create audit signals.

Line 43 — Date placed in service

“When did you place your vehicle in service for business purposes?” Format MM/DD/YYYY. For a car you owned before going self-employed, “placed in service” means the first day you started using it for business. If you started rideshare on March 14, 2026, that’s the date — not the date you bought the car years earlier.

Line 44 — Mileage breakdown

You report three buckets totaling your year’s odometer:

• 44a Business — the miles you’re deducting on Line 9. From your contemporaneous log.
• 44b Commuting — the miles between your home and a regular work location that the IRS treats as nondeductible personal travel. For a delivery driver whose home qualifies as a §280A home office under Rev. Rul. 99-7 Situation 3, commuting miles are typically zero. For a hybrid worker driving to a W-2 office before logging into Uber, commuting miles are the home-to-W2-office leg. We unpack the §280A unlock in our What Counts as a Business Mile pillar.
• 44c Other — personal driving (groceries, school pickup, weekend trips).

These three numbers should add up to your annual odometer change. The IRS doesn’t formally check, but a mismatch on audit is bad.

Line 45 — Was your vehicle available for personal use during off-duty hours?

For almost every gig driver, the honest answer is Yes. You drive your daily-driver Honda for Uber. It’s not a dedicated business vehicle. Saying “No” with one car in the household is a red flag.

Line 46 — Do you (or your spouse) have another vehicle available for personal use?

A second car in the household helps the credibility of your business-use percentage. If you said No to Line 46 (one car only) AND Yes to “high business use” (say, 22,000 of 30,000 miles), the IRS computer notices.

Line 47a — Do you have evidence to support your deduction?

The correct answer is Yes. If it’s No, you lose §274(d) and the deduction.

Line 47b — If “Yes,” is the evidence written?

The correct answer is Yes. Written under Treas. Reg. §1.274-5T(c)(2)(ii)(A) includes contemporaneous electronic records — exactly what Patitz v. Commissioner, T.C. Memo. 2022-99 accepted, and what Velez v. Commissioner, T.C. Memo. 2018-46 rejected when reconstructed after the fact.

The Part IV audit-bait pattern

The combination that lights up IRS scoring models: high business miles + zero commuting miles + only one vehicle in the household + the vehicle is available for personal use. It can be perfectly legitimate (you qualify under Rev. Rul. 99-7 Situation 3 and your only car is also your business car), but you should expect a question and have records ready. We built our entire Mileage Audit Defense Playbook around this scenario.

Line 27b and Part V — driver-specific gear

Standard mileage covers the vehicle. It does not cover the stuff that makes you a driver. That stuff lives on Schedule C Part V, totals to Line 48, and flows to Line 27b.

For delivery drivers, Part V typically includes:

• Insulated hot bags, cold bags, and pizza bags
• Reusable totes for grocery delivery (Instacart, Spark, Shipt)
• Phone mount and dual chargers
• Dash cam (for liability documentation)
• Onboarding fees and platform background-check fees
• Vehicle inspection fees the platform required
• A modest portion of “vehicle cleanings” beyond the 72.5¢ rate (debatable — some practitioners include car washes here when proportional to business use; conservative preparers absorb car wash into the standard rate)

For rideshare drivers, add:

• Water, mints, snacks, and similar amenities for passengers (deductible as ordinary and necessary under §162(a))
• Aux cables, phone chargers for passengers
• Tissues, hand sanitizer, gum
• Tolls transponder annual fees (the service fee portion; tolls themselves are Line 9)
• Roadside assistance plan business-portion

The Part V format is a labeled list. Write “Hot/cold bags,” then a dollar amount. Write “Phone mount,” then a dollar amount. Add them up on Line 48. Don’t combine everything into one giant “supplies” line — itemize at the category level so an IRS auditor can see what they’re looking at.

You’ll find 47 more concrete examples in our What Counts as a Business Mile pillar.

Other Schedule C lines vehicle-related

Standard mileage absorbs most car costs, but several other Schedule C lines remain in play.

Line 15 — Insurance (other than health). Under standard mileage, your personal-auto insurance is baked in. Don’t double-deduct. But if you carry a separate rideshare endorsement or a true commercial auto policy that’s clearly above and beyond standard personal coverage, the extra premium is arguably deductible here — though many preparers absorb it into the standard rate to avoid argument. Under actual expenses, the full business-use portion of insurance goes on Line 15.

Line 16b — Other interest. This is the line drivers most often miss. If you financed your car and use it partly for business, the business-use percentage of your vehicle loan interest is deductible on Line 16b on top of the standard mileage rate. A driver paying $1,800 of car loan interest in 2026 with 73% business use deducts $1,314 on Line 16b. Most TurboTax flows do not catch this. Note the OBBBA tie-in: the personal-use portion of qualifying car loan interest (loans originated after 12/31/2024, secured by first lien, VIN reported) may now be deductible on Schedule 1-A Part IV under §163(h)(4). You cannot deduct the same dollar twice — Schedule C Line 16b for the business portion, Schedule 1-A Part IV for the personal portion, and the form Part IV has a column noting amounts also deducted on Schedule C.

Line 21 — Repairs and maintenance. Vehicle repairs go here only if you’re using actual expenses, not standard mileage. Standard mileage absorbs repairs.

Line 22 — Supplies. Gas under actual expenses traditionally lands on Line 9 (some practitioners use Line 22). For drivers, this is also the right line for windshield wiper fluid, cleaning supplies, and similar consumables — even under standard mileage if they relate to delivery operations rather than vehicle operation.

Line 23 — Taxes and licenses. Personal property tax on a vehicle (in states that levy one — Virginia, Missouri, parts of South Carolina), business portion, is deductible here on top of the standard mileage rate. Business license fees and platform city permits also belong here.

Line 25 — Utilities. The business-use percentage of your cell phone bill belongs here. If your monthly bill is $90 and 60% of usage is platform apps, $54/month × 12 = $648 deductible. Be honest with the percentage — and keep a one-month usage log to defend it.

Form 4562 — the actual-expense and depreciation walkthrough

If you take standard mileage on one vehicle and have no other depreciation activity, you may never see Form 4562. But you must file Form 4562 in any of these situations:

1. You’re claiming actual expenses on a vehicle for the first year it was placed in service.
2. You’re claiming §179 expensing on the vehicle.
3. You’re claiming bonus depreciation under §168(k).
4. You’re depreciating a vehicle (even via straight-line) that you’ve owned for multiple years and continue actual expenses on.
5. You have two or more vehicles in business use, since Schedule C Part IV has room for only one.
6. You’re depreciating any business property (laptops, hot-bag warmers, dashcams above the de minimis threshold).

Form 4562 has six parts. For drivers, Part V — Listed Property is the heart of the form.

Part I — §179 Expense Election (Lines 1–13)

§179 lets you immediately expense up to a dollar cap of qualifying business property in the year placed in service. For 2026, under OBBBA §70306, the cap is $2,560,000 with a phase-out starting at $4,090,000 of total §179 property — limits no individual driver will approach.

The catch for vehicle drivers: §280F caps how much §179 you can claim on a passenger automobile. And for heavy SUVs (>6,000 lb GVWR but ≤14,000 lb) — the famous “Hummer loophole” — OBBBA §70306 sets a sub-cap of $32,000 for 2026 (up from $31,300 in 2025).

Line 1 is the maximum amount ($2,560,000); Line 2 is total cost of §179 property; Line 5 is the dollar limitation for the year; Line 6 is where you list each property; Line 12 is your final §179 expense deduction; Line 13 carries forward any disallowed amount.

Part II — Special Depreciation Allowance (bonus depreciation)

This is where bonus depreciation under §168(k) lives. OBBBA §70301 made 100% bonus depreciation permanent for property acquired and placed in service after January 19, 2025. Property acquired before 1/20/2025 and placed in service in 2026 still follows the old phase-down schedule.

For drivers, this matters mainly if you bought a vehicle for business use in 2026: you can deduct 100% of the basis (subject to §280F caps for cars, the heavy-SUV sub-cap for trucks/SUVs over 6,000 lbs).

Part III — MACRS Depreciation

Passenger automobiles are 5-year property under MACRS. Section B Line 19b is where new-this-year 5-year property is depreciated using GDS half-year (or mid-quarter) conventions. The first-year MACRS percentage for 5-year property with the half-year convention is 20%.

Part IV — Summary

Line 21 picks up the listed property total from Part V Line 28. Line 22 sums everything and is where you find the number that goes to Schedule C Line 13. This is how depreciation flows to Schedule C.

Part V — Listed Property (the vehicle section)

Section A — Depreciation and Other Information

• Line 24a — “Do you have evidence to support the business/investment use claimed?” Same question as Schedule C Line 47a.
• Line 24b — “If ‘Yes,’ is the evidence written?” Same as 47b.
• Line 25 — Special depreciation allowance for qualified listed property used more than 50% in qualified business use.
• Line 26 — Listed property used more than 50% in qualified business use. Columns: description; date placed in service; business/investment use %; cost or other basis; basis for depreciation; recovery period; method/convention; depreciation deduction; §179 elected cost.
• Line 27 — Listed property used 50% or less. Limited to straight-line depreciation, no §179, no bonus.
• Line 28 — total to Line 21.

Section B — Information on Use of Vehicles

• Line 30 Total business/investment miles (excluding commuting)
• Line 31 Total commuting miles
• Line 32 Total other personal miles
• Line 33 Total miles
• Line 34 Available for personal use after-hours?
• Line 35 Used primarily by a >5% owner or related person?
• Line 36 Another vehicle available?

This mirrors Schedule C Part IV but is finer-grained and required for each business vehicle.

Section C — Questions for Employers Who Provide Vehicles to Employees (Lines 37–41) — almost never applies to a sole-proprietor driver. Skip.

§280F luxury auto caps — the ceiling on passenger autos

Rev. Proc. 2026-15 sets the 2026 §280F annual depreciation ceilings:

Year	With bonus	Without bonus
Year 1	$20,300	$12,300
Year 2	$19,800	$19,800
Year 3	$11,900	$11,900
Year 4+	$7,160	$7,160

These caps apply to passenger automobiles — basically, cars and SUVs with a GVWR of 6,000 lbs or less. The caps cut off how much depreciation (including §179 and bonus) you can take per year, regardless of vehicle cost. A $60,000 Tesla Model S placed in service in 2026 with bonus claimed is capped at $20,300 of depreciation in year one.

The heavy SUV escape hatch

Vehicles with a GVWR above 6,000 lbs but not more than 14,000 lbs are not “passenger automobiles” for §280F purposes. They escape the caps. The catch: OBBBA §70306 capped the §179 deduction for heavy SUVs at $32,000 for 2026. Bonus depreciation has no sub-cap, so a $90,000 heavy SUV placed in service in 2026 can take $32,000 §179 plus 100% bonus on the remaining $58,000 — meaning effectively full expensing in year one.

This is, in our view, the wrong path for almost every gig driver. See our Standard Mileage vs. Actual Expenses pillar for the math.

The §280F(b)(2) recapture trap

If you take §179 or bonus depreciation on a vehicle and your business use drops below 50% in a later year, §280F(b)(2) recaptures the “excess depreciation” — the amount you depreciated above what straight-line would have given you. That recapture lands as ordinary income on Schedule C Line 6 (other income). Drivers who go heavy on year-one depreciation and then slow down their driving in year three get a nasty surprise.

Why most drivers should not go down this road

Form 4562 is the right path for the relatively rare driver who buys a heavy-SUV-class vehicle dedicated to business or who has a high-cost vehicle with very high business-use percentage. For the typical Uber/DoorDash driver in a Honda Civic, standard mileage wins on dollars and simplicity, and you skip Form 4562 entirely.

Schedule SE — how vehicle deductions cut your SE tax

Schedule SE calculates your self-employment tax — the FICA-equivalent that funds Social Security and Medicare for self-employed taxpayers. This is where most drivers feel the actual dollar impact of their mileage deduction.

The mechanics

• Line 2 pulls in your Schedule C Line 31 net profit.
• Line 4a multiplies by 92.35% — the standard adjustment that excludes the “employer half” of FICA from the SE tax base.
• Line 7 caps the Social Security portion at the year’s wage base. For 2025, $176,100 (preprinted on the 2025 form). For 2026, $184,500 (SSA announcement, October 2025).
• Line 10 computes 12.4% SS tax on net earnings up to the wage base.
• Line 11 computes 2.9% Medicare tax on the full Line 6 amount (no cap).
• Line 12 sums them — your total SE tax. Flows to Schedule 2 (Form 1040), Line 4.
• Line 13 is the §164(f) deduction for half of your SE tax, which flows to Schedule 1, Line 15 — an above-the-line adjustment that reduces AGI.

The effective rate

Statutory rate: 15.3% (12.4% SS + 2.9% Medicare). After the 92.35% adjustment, the effective rate on each dollar of net profit below the SS wage base is roughly 14.13%: 0.9235 × 0.153 = 0.14129. Above the SS wage base, the effective rate on each additional dollar drops to 0.9235 × 0.029 = 2.68%.

Why this is the deduction that pays

Every dollar of mileage you deduct on Schedule C Line 9 reduces Schedule C Line 31, which reduces Schedule SE Line 2, which reduces SE tax by ~14.13¢ per dollar of mileage below the SS wage base — on top of your marginal federal income tax. If you’re in the 22% federal bracket and below the SS wage base, every $1 of mileage saves you roughly $0.36 in combined federal taxes.

This is why mileage tracking matters so much for self-employed drivers in a way W-2 employees can’t replicate. The misc-itemized deduction repeal under OBBBA §70110 made it permanent: a W-2 driver cannot deduct unreimbursed mileage on Schedule A. Only Schedule C filers can.

Form 8829 — the home office cross-reference

Form 8829 doesn’t directly touch vehicle expenses. But qualifying a home office under §280A(c)(1)(A) does something powerful: it unlocks Rev. Rul. 99-7 Situation 3, which treats driving between your home office and any other work location in the same trade or business as deductible business mileage, not commuting.

For a delivery driver who manages logistics, accepts and rejects offers, schedules shifts, and does platform admin from a dedicated area of their home, this can mean the first trip of the day and the last trip home count as business miles instead of commuting — often 3,000–5,000 miles a year.

Form 8829 itself calculates the home office deduction (utilities, rent or mortgage interest, depreciation) based on square footage. The output flows to Schedule C Line 30. The vehicle benefit, though, is captured entirely on Line 9 — more business miles, same form, more deduction.

We walk the home-office mechanics in our Freelancer + 1099 Mileage Schedule C pillar and our Mileage Tracking for Real Estate Agents pillar.

Complete worked example — Marcus, multi-platform delivery driver, 2026

To make this concrete, let’s walk a full Schedule C for a real-looking driver.

Marcus’s facts

• Drives DoorDash, Uber Eats, and Walmart Spark from his home in Dallas, TX
• Files single, no dependents, age 34
• Uses a 2022 Honda Civic he placed in service for business on January 1, 2024 (so this is year 3 of business use)
• Took standard mileage in year one — election preserved for life of vehicle
• 2026 odometer: 30,000 miles total
  • 22,000 business miles (DoorDash 12,000, Uber Eats 7,000, Spark 3,000)
  • 0 commuting miles (qualifies §280A home office — uses a dedicated 80 sq ft area of his apartment exclusively and regularly for dispatch and admin)
  • 8,000 personal miles
• 2026 gross receipts: $48,000 (DoorDash $26,500; Uber Eats $14,200; Spark $7,300) — all received via three 1099-NECs
• Tips totaled $5,800 across platforms, included in gross receipts above. Marcus is in a Treasury Tipped Occupation Code (TTOC) for delivery drivers; tips qualify for §224 deduction.
• Parking and tolls during business driving: $480
• Phone mount, hot bags, dash cam, supplies: $410 total
• Cell phone bill: $90/month, 65% business use
• Vehicle loan interest paid in 2026: $1,920; business-use percentage = 73% (22,000/30,000)
• Home office Form 8829 computed deduction: $1,440

Schedule C — Marcus’s filled-in form

Schedule SE — Marcus’s SE tax

Schedule 1-A — Marcus’s tip deduction

What Marcus actually owes (high-level)

This is the entire point of the deduction system — and exactly why drivers without contemporaneous logs lose so badly under §274(d).

A note on the form you’re actually filing

The line numbers and labels in this article reflect the 2025 Schedule C, Form 4562, Schedule SE, and Schedule 1-A as published on IRS.gov for the tax year 2025 (filed in calendar year 2026). Forms change. If you’re filing for tax year 2026 in calendar 2027, verify the line numbers against the then-current forms — particularly Part II Lines 27a/27b, which the IRS reorganized for 2025. Our OBBBA Tax Changes for Self-Employed Drivers pillar tracks the moving pieces.

The bottom line

Schedule C is a map, and the vehicle expense path runs through three landmarks: Line 9, Part IV, and (sometimes) Form 4562 Part V. Standard mileage at 72.5¢/mile is the cleanest, cheapest, most defensible route for almost every gig driver. The deduction works against both your income tax and your self-employment tax, which is why even modest mileage logs translate into thousands of dollars of savings.

The deduction lives or dies on records. §274(d) does not care that you “definitely drove a lot.” It does not let Cohan save you. It demands a contemporaneous, written (or electronic) record of every business trip — the date, the miles, the business purpose. That requirement is exactly what an automatic GPS mileage app is designed to satisfy.

Frequently asked questions

Do I file one Schedule C or multiple for Uber, Lyft, and DoorDash?

File one Schedule C if all your driving activities are part of the same trade or business — which the IRS generally considers to be the case for transportation services (rideshare + delivery combined). Pick the NAICS code for your majority activity. If you do something genuinely different on the side — say, freelance graphic design — that warrants its own Schedule C.

What's the 2026 IRS standard mileage rate?

72.5¢ per mile for business under IRS Notice 2026-10. The depreciation portion baked in is 35¢/mile.

What goes on Schedule C Line 9 vs. Line 13?

Line 9 is car and truck expenses — standard mileage OR the operating portion of actual expenses (gas, oil, repairs, insurance, registration), plus parking and tolls. Line 13 is depreciation and §179, which is only used when you take actual expenses and are depreciating the vehicle via Form 4562.

Can I switch from standard mileage to actual expenses next year?

Yes — with a catch. Switching forces you onto straight-line depreciation over the vehicle's remaining useful life under §280F, not the faster MACRS method. And switching from actual to standard is only permitted if you elected standard in year one — see Rev. Proc. 2019-46.

Do I have to file Form 4562 if I take standard mileage?

Generally no — Schedule C Part IV captures the substantiation. You must file Form 4562 if you have two or more business vehicles, claim §179, claim bonus depreciation, claim actual-expense depreciation, or are in the first year you placed any business asset in service (including vehicles under actual expenses).

Are parking and tolls deductible on top of the standard mileage rate?

Yes. Parking and tolls during business driving are added to Schedule C Line 9 alongside the per-mile amount. Parking tickets and fines are not deductible.

Can I deduct car loan interest as a self-employed driver?

Yes — the business-use portion on Schedule C Line 16b, on top of standard mileage. The personal-use portion of qualifying loans (originated after 12/31/2024, secured by first lien, VIN reported) may be deductible on Schedule 1-A Part IV under §163(h)(4) (OBBBA §70203). You cannot deduct the same dollar twice.

Are my Uber or DoorDash tips eligible for the §224 No Tax on Tips deduction?

Yes if you're in an occupation on Treasury's Tipped Occupation Code list (rideshare and food delivery couriers are included per final regulations released May 2026). The deduction caps at $25,000, phases out starting at $150,000 MAGI single / $300,000 joint, and is claimed on Schedule 1-A Part II Line 5 for self-employed taxpayers, flowing to Form 1040 Line 13b.

Does the tip deduction reduce my self-employment tax?

No. §224 is a federal income tax deduction taken after AGI. Tips are still included in Schedule C gross receipts and SE tax is still calculated on full Schedule C net profit. This is the most misunderstood OBBBA driver provision.

What NAICS business code do I use?

485300 for rideshare (Uber, Lyft); 492000 for delivery (DoorDash, Uber Eats, Spark, Instacart, Grubhub, Amazon Flex); 531210 for real estate agents; 711510 for freelance creative work.

What's the difference between Line 27a and Line 27b for 2025?

The IRS reorganized the 2025 form. Line 27a is now Energy efficient commercial buildings deduction (Form 7205) — a niche line most drivers ignore. Line 27b is Other expenses (from Line 48) — the catch-all that picks up Part V totals. Older guides referencing Line 27a — other expenses are out of date.

Can I take Section 179 on my rideshare vehicle?

Technically yes, with severe caps. §280F limits passenger autos to $12,300 Y1 without bonus / $20,300 with bonus for 2026. Heavy SUVs (>6,000 lb GVWR) escape §280F but face the OBBBA §70306 $32,000 §179 sub-cap. And — critically — taking §179 in year one locks you out of standard mileage forever on that vehicle. For most drivers, the math says don't.

What if my business use drops below 50%?

You trigger §280F(b)(2) recapture. The excess depreciation — the amount above what straight-line would have given you — flips back as ordinary income on Schedule C Line 6. If you took §179 or bonus, the recapture can be substantial.

Are commuting miles deductible for a gig driver?

Not under the general commuting rule. But Rev. Rul. 99-7 creates three exceptions, and Situation 3 is the gig driver's friend: if your home qualifies as a §280A home office, trips between home and any business work location in the same trade or business are deductible — meaning your first and last trip of the day count as business miles, not commuting.

Do I need a [mileage log](/glossary/mileage-log)? What if I forgot to keep one?

Yes, and what-if-I-forgot is the most expensive question in driver tax. §274(d) demands strict, contemporaneous substantiation. Reconstructed logs can be tried, but the leading cases — Velez, Royster, DeLima — consistently disallow reconstructions that aren't backed by genuinely contemporaneous source records. Patitz v. Commissioner accepted electronic records that were created contemporaneously. The lesson: capture trips automatically as they happen, not in April.
