Why One Turo Exotic Usually Deducts $20,300, Not Its Price

We got this question recently, in almost exactly these words: "If I bought a Ferrari and rented it on Turo, how many days do I need to rent it to take bonus depreciation without it being weird?"

The tax code never counts rental days for this. It asks two other things: whether the car is light enough to fall under the luxury auto limits, and whether you are in the business of renting cars or just renting one out. Price barely enters into it.

1 There is no day count

Bonus depreciation is back at 100% for property acquired after January 19, 2025, and the 2025 tax law removed the phase-down, so it stays at 100%. A car you buy and put on Turo in 2026 qualifies for it on paper.

What decides how much of it you get is section 280F, the part of the code written to stop people deducting expensive personal cars. Nothing in section 280F or its regulations sets a minimum number of rental days, so if someone quotes you one, ask them for the cite.

2 A sports car is light enough to hit the cap

Section 280F caps depreciation on a "passenger automobile," which for a car means one rated at 6,000 pounds unloaded gross vehicle weight or less. Trucks and vans are measured by loaded weight instead. A Ferrari coupe, a Porsche 911 or a McLaren weighs well under 6,000 pounds unloaded.

Once a car is under the cap, the purchase price stops mattering for the first few years. Rev. Proc. 2026-15 sets the 2026 limits:

At $7,160 a year after year three, a car that cost $180,000 would take well over a decade to fully deduct. In practice you sell it first, and the sale settles the rest (section 7).

3 The leasing exception is written for fleets

Section 280F has a way out. Section 280F(c)(1) says the section "shall not apply to any listed property leased or held for leasing by any person regularly engaged in the business of leasing such property." That is the rule that lets Hertz depreciate its sedans without the luxury cap. If you qualify, the cap and the 50% business-use test both go away, and 100% bonus applies to the full price.

The regulation defines "regularly engaged" as entering into leases "with some frequency over a continuous period of time," judged on all the facts. Then it gives one example:

A host who rents one Ferrari to forty different guests could argue that is forty leases, not one. We read the example as being about cars, not contracts, and we would not take the full deduction on a single exotic and expect it to hold up. A host running several cars, listed all year, with steady bookings, has a real argument.

4 Without the exception, rentals must be more than half the use

If the leasing exception does not apply, you can still take the capped amount, but only if the car is used more than 50% for business in that year. Fall to 50% or below and you lose bonus and accelerated depreciation for that year and switch to the slower straight-line method. If that happens in a later year, you add back the extra depreciation you took earlier as income.

Two details catch Turo hosts:

• Renting to family does not count. Rentals to a 5% owner or a related person are not qualified business use.
• The records have to exist. For a car, section 274(d) and its regulations disallow the deduction unless you can show the amount, including business and total miles, the date of each use, and the business purpose. Keep the Turo trip history, and log every personal drive with its date and miles.

5 The seven-day rule decides whether the loss offsets your salary

A depreciation deduction is only worth something if the loss can offset your other income. This is the same question short-term rental owners face, and the same rule answers it.

When the average rental lasts seven days or less, the IRS does not treat the activity as a "rental activity" under the passive loss rules. If your average Turo trip is a week or less, your car falls here. Check the average each year, because a few month-long bookings can pull it over seven days. So it is treated like any other business, and the loss offsets wages and other income only if you materially participate.

For a one-car host, the usual test is more than 100 hours in the year and no less than any other individual. Turo staff and a co-host count as other individuals. If a co-host does the cleaning, handoffs and messages, they likely outwork you, and the loss becomes passive. It then waits until you have passive income or sell the car.

A very large loss also runs into the excess business loss limit, $256,000 single and $512,000 joint for 2026. One car rarely reaches it, though a fleet can.

6 A $180,000 car, both ways

Take a car bought for $180,000 and listed on Turo all of 2026 with no personal use, by a host in the 37% bracket who materially participates.

Most of that is timing, though. Say the host sells the car three years later for $130,000:

On the bonus path, the host deducts $180,000 up front and reports $130,000 of ordinary income on the sale. On the capped path, the host deducts less each year and has a smaller gain at the end. Both land on the $50,000 the car actually lost in value. Bonus changes when you get the deduction, not how much.

7 What you owe when you sell

A car is section 1245 property. When you sell it, any gain up to the depreciation you took is taxed as ordinary income, at your regular rate. The 25% rate that applies to depreciation on buildings does not apply to cars.

So a full deduction at 37% followed by a sale taxed at 37% is close to an interest-free loan from the IRS until you sell. That loan is worth having, but a cash-flow model that leaves out the tax on the sale will be wrong in the year you sell.

8 If the IRS disagrees

Suppose you take the full $180,000 and an audit decides you were not regularly engaged in leasing. You keep the $20,300 the cap allows, and owe tax on the other $159,700:

• Back tax: $59,089 at 37%.
• Accuracy penalty: 20% of the underpayment, about $11,818, if the understatement tops the greater of $5,000 or 10% of the correct tax (5% if you claim the section 199A deduction).
• Interest: 7% a year for the fourth quarter of 2026, compounded daily, from the original due date.

The penalty does not apply if you had reasonable cause and acted in good faith, which usually means relying on a qualified preparer who had all the facts. Disclosure is harder here than usual. A full deduction on one car runs against the regulation's own example, and a position contrary to a regulation has to be disclosed on Form 8275-R, as a good-faith challenge to the regulation itself. That is a weak place to be with one car, which is why we plan on the cap.

9 What to do before you buy

• Check Turo will take the car. Turo's standard limit is a fair market value of $200,000, 12 years old and 130,000 miles. A new Ferrari is often over the value limit, and you have to contact Turo before listing it.
• Decide which path you are on. One car: plan on the cap. Several cars, listed all year: the leasing exception is worth discussing.
• List it before December 31. Depreciation starts in the year the car is ready and available to rent, and a live listing is the best evidence of that. A car bought in December that is not ready to rent until January is a 2027 deduction.
• Keep an hours log from day one. Cleaning, handoffs, guest messages, maintenance runs. The 100-hour test is decided on this log.
• Run it like a business. A separate bank account and a real profit motive. An activity that shows a profit in 3 of 5 years is presumed to be for profit. If a Ferrari loses money every year, expect the IRS to ask whether it is a hobby.

If you are pricing an exotic for Turo, run the numbers both ways before you sign the purchase contract, not after. Our tax planning team models the capped and uncapped paths, the material participation test and the sale, before you commit to the car.
