Turo Bonus Depreciation in 2026: How the OBBBA Restored the 100% Write-Off

This is educational, not tax advice — depreciation outcomes depend on facts specific to you, and the numbers below are illustrative. Use this to understand the mechanics and ask your CPA sharper questions before you buy anything or file anything.

What bonus depreciation actually does

Normally, when a business buys a vehicle, it deducts the cost slowly over several years through a schedule called MACRS. Bonus depreciation lets you pull a large share of that deduction into Year 1 instead of waiting. Under the One Big Beautiful Bill Act, the first-year bonus rate is back to 100% for qualifying property — meaning, in the right circumstances, you can deduct the full business-use cost of a vehicle the same year you place it in service.

For a Turo host, that is the difference between a $30,000 car deducted a few thousand dollars at a time and a $30,000 car that produces a five-figure deduction in the year you buy it. That deduction is what can offset other income and lower your tax bill.

Bonus depreciation vs. Section 179 vs. MACRS

Three tools get confused constantly. The short version:

• MACRS — the default. Spreads the deduction over the vehicle's recovery period. No special election needed.
• Section 179 — lets you expense the cost up front, but it is capped at a dollar limit and cannot create a loss — it can only zero out business income, not go beyond it.
• Bonus depreciation — also front-loads the deduction, but has no dollar cap and can create a loss that may offset other income.

The "can it create a loss" difference is the whole game for a W-2 earner: a loss is what reaches beyond the Turo business and reduces other income.

Which one wins depends on your full picture, and they can be layered. This is exactly the kind of thing to model before you file — not guess at.

The business-use rule that gates everything

Bonus depreciation on a vehicle is scaled by its business-use percentage, and to use the accelerated methods at all, business use generally has to be more than 50%. A car rented on Turo 80% of the time and driven personally 20% does not get a 100% deduction — it gets the deduction on the 80% that is business use.

This is why a clean mileage and usage log is not optional. The deduction is only as defensible as the records that prove the business-use percentage. If the log does not exist, the percentage — and the deduction built on it — is exposed on audit.

The heavy-vehicle wrinkle Turo hosts should understand

Ordinary passenger cars are subject to annual "luxury auto" depreciation caps that limit how much you can write off in Year 1, even with bonus depreciation. But vehicles above a certain gross vehicle weight rating (the often-cited 6,000-lb GVWR threshold for many large SUVs and trucks) are treated differently and can escape those passenger-auto caps.

That is why you see fleet operators paying close attention to vehicle weight class when the tax deduction is part of the buying decision. It does not mean a heavy SUV is always the right business choice — it still has to earn on Turo — but the depreciation treatment is genuinely different, and it belongs in the math before you buy.

The catch nobody mentions: recapture when you sell

A large Year-1 deduction is not free money — it is a timing move. When you sell or dispose of a vehicle you depreciated, some or all of that deduction can come back as depreciation recapture, taxed as ordinary income (the Section 1245 rules). A host who wrote a car down to near zero and then sells it can face a recapture bill on the sale.

That does not make bonus depreciation a bad deal — deferring tax and controlling when you recognize income is valuable. But it means the exit matters as much as the purchase, and "I already deducted it" is not the end of the story. Plan the buy and the eventual sale together.

Whether it offsets your W-2 income at all

The dream scenario — using a Turo vehicle loss to lower the tax on a high W-2 salary — depends on whether your Turo activity is treated as one you materially participate in, versus a passive activity. This ties back to how the income is classified and rules like the short-average-rental ("7-day") test. Get that classification wrong and the loss may be trapped as passive, unable to touch your W-2 income.

So the sequence is: confirm the activity qualifies, keep the records that prove business use and participation, then let bonus depreciation do its work. Skip the first two steps and the third one may not deliver what you expected.

How FK Command Center helps you model it

FK Command Center does not file your return, and it is not a substitute for your CPA. What it does is run the numbers the decision needs: it models bonus depreciation, Section 179, and MACRS against a specific vehicle and your business-use percentage, tracks the mileage and participation records that make the deduction defensible, and flags the recapture exposure sitting inside a future sale. When you walk into your CPA's office, you bring a modeled position instead of a question — which is how these deductions actually get captured instead of missed.
