Whether Turo hosts can use the standard mileage rate, why the actual expense method is the default for rental vehicles, the five-car fleet rule, and how to switch methods without losing depreciation.
New hosts arrive at their first tax season with a question borrowed from rideshare: “Do I take mileage or actual expenses?”
For a Turo fleet, it’s mostly the wrong question — and understanding why saves you from choosing the wrong method in year one and being stuck with it.
Standard mileage. You multiply business miles by a flat IRS rate — 70 cents per mile for 2025; for 2026 it is 72.5 cents through June 30 and 76 cents from July 1 (the IRS raised it mid-year for fuel costs) — and that number stands in for gas, oil, maintenance, tires, insurance, registration and depreciation. You can still separately deduct parking, tolls, and interest on the car loan (business portion). It exists so a salesperson doesn’t have to keep every gas receipt.
Actual expenses. You deduct what the car actually cost to own and run — depreciation (or lease payments), insurance, repairs and maintenance, tires, registration, loan interest, cleaning, and so on — multiplied by the vehicle’s business-use percentage. Every dollar needs a record.
Three reasons, in increasing order of finality.
The standard mileage rate is a substitute for the cost of your business driving. Turo miles are driven by guests. You can make an argument that a delivery-and-pickup mile is business driving, but the 8,000 miles a guest put on the car last quarter aren’t yours in the way the rate contemplates. Most tax professionals treat a Turo vehicle as a rental asset — property placed in service in a rental business — not as a car you drive for work.
The mileage rate bundles depreciation at a modest assumed pace. A car bought for the fleet depreciates far faster than that in the early years, and the actual method lets you deduct that reality — through MACRS, bonus depreciation, and in some cases Section 179 (see Turo depreciation and MACRS). For a $30,000 vehicle in year one, the difference can be five figures.
The IRS bars the standard mileage rate if you use five or more cars at the same time in the business. Publication 463 calls this “fleet operations.” Rotating five cars through the same period counts. Once you’re a real fleet, actual expenses is the only method available.
Be honest about how narrow this is:
Even then, run both numbers. If the vehicle earned meaningful revenue, actual expenses almost always wins.
The order you pick methods matters:
Practically: for a car you intend to run on Turo for a few years, start with actual expenses and accelerated depreciation in year one. Retrofitting later costs you.
The method’s only real cost is record-keeping. Per vehicle:
Bundle receipts by vehicle, not by month. At tax time your CPA needs “everything about the 2022 Model Y,” not “everything from March.”
Say a $28,000 vehicle ran 14,000 guest miles in its first year (2025, at the 70¢ rate) and cost $6,400 to insure, maintain, clean and register, with $900 of loan interest.
| Standard mileage | Actual expenses | |
|---|---|---|
| Mileage deduction | 14,000 × $0.70 = $9,800 | — |
| Operating costs | included in rate | $6,400 |
| Loan interest | $900 (allowed separately) | $900 |
| Depreciation (year 1, MACRS 5-yr, half-year) | included in rate | ~$5,600 — or far more with bonus, subject to luxury-auto caps |
| Total | ≈ $10,700 | ≈ $12,900+ |
And that’s before considering bonus depreciation, which can push year-one actual expenses much higher for a qualifying vehicle. Scale to five cars and the gap is the fleet’s entire margin.
The actual expense method is where the Turo tax deductions checklist lives — depreciation is just the largest line on it. It feeds Schedule C, which is why per-vehicle books matter: the IRS wants each vehicle’s depreciation on its own schedule (Form 4562), and you want each vehicle’s true profit for deciding which car to sell next.
FleetPilot tracks costs per VIN from the day a vehicle enters the fleet — receipts, bank transactions, tolls, and claims matched to the right car — and carries the depreciation schedule alongside it, so the “actual expenses” for every vehicle are a report your CPA can file from rather than a shoebox.

In narrow cases — a single vehicle, first year, business use you can substantiate — but it rarely fits. (The rate is 70¢ per mile for 2025; 72.5¢ for January–June 2026 and 76¢ from July 1, 2026.) The rate is designed for a taxpayer's own business driving; Turo miles are driven by guests. Hosts who use five or more vehicles at the same time cannot use it at all. Almost every professional host uses the actual expense method.
You deduct the real, documented costs of the vehicle — depreciation, insurance, maintenance and repairs, tires, registration, loan interest, cleaning, and similar — multiplied by the vehicle's business-use percentage. For a car used only for Turo, that is 100%.
You can switch from standard mileage to actual in a later year, but you must then use straight-line depreciation for that car for the rest of its life. You generally cannot switch from actual (with accelerated depreciation) back to standard mileage on the same vehicle.
Guest miles are use of the vehicle in your rental business, which supports the business-use percentage under the actual method. They are not miles you drove for business in the sense the standard mileage rate contemplates, which is a core reason the rate is a poor fit for Turo.
Turo uses "co-host" to mean two completely different things, and conflating them costs owners and operators real money. Here's how the programs differ, what each split actually pays, and what you need in place to run this as a business.
The 1099-K reports gross bookings, not what Turo paid you. Here's who gets one, why the number looks too high, and how to reconcile it so you don't pay tax on Turo's cut.
