Business Depreciation: Vehicles, Timing, and Recapture

Updated October 21, 2026

The Part After the Write-Off Everyone Talks About

The equipment financing guide covers Section 179 and how the way you finance a purchase affects whether you can claim it. Quick version for anyone landing here first: Section 179 lets you deduct the full cost of qualifying equipment in the year you put it to work, up to $2,560,000 for 2026. Bonus depreciation, now permanently back at 100% for property acquired after January 19, 2025, can cover whatever Section 179 doesn’t.

What that piece doesn’t cover, and what actually trips people up, is everything around that write-off. Vehicles get their own, stricter rules. There’s a solid case for not always taking the biggest deduction right away. And the depreciation you claim today isn’t free forever. It can come back as a real tax bill the year you sell or trade in the equipment.

Short version: Section 179 and bonus depreciation can write off most equipment in year one, but vehicles have their own caps based on weight and body style, and they only qualify if you use them more than 50% for business. Full expensing isn’t automatically the smartest move if this year’s income is low or next year’s looks much higher. And depreciation you claim today generally gets taxed back as ordinary income if you later sell or trade in the equipment for more than its remaining tax value.

Section 179 vs. Bonus Depreciation: The One Difference That Decides Which You Use

Both let you deduct the full cost of qualifying property right away instead of spreading it over several years. The real difference is what happens when your income is low.

Section 179 is capped at your taxable income from active business for the year. It can bring that income down to zero, but it can’t push you into a loss. One detail most people miss: for this limit, the IRS counts wages from a regular job too, not just your business profit. So if you run a side business while working a W-2 job, your paycheck can help absorb a big Section 179 deduction. If there still isn’t enough income, the unused part carries forward to future years with no expiration. Buy $50,000 of equipment in a year when your business and wages together only total $30,000, and you deduct $30,000 now and carry the other $20,000 forward.

Bonus depreciation has no income limit. It can create or deepen a business loss, which becomes a net operating loss you carry forward against future income. In a strong year, the difference rarely matters, since most people use both together: Section 179 on the specific assets they want to control, bonus depreciation on the rest. In a slow year, it matters a lot, because bonus depreciation still works after Section 179 runs out of income to offset.

Small Purchases: You May Not Need Depreciation at All

For tools and smaller equipment, there’s a simpler option. The IRS de minimis safe harbor lets most small businesses write off items costing $2,500 or less per item (or per invoice) as a regular expense, no depreciation schedule needed. A $1,200 impact gun set or a $2,000 scan tool can just be expensed. You make the election each year with a statement attached to your return, and it keeps your records a lot cleaner than tracking dozens of small assets.

The Vehicle Rules That Override Everything Above

Here’s where a lot of general depreciation advice falls apart the moment it touches a work truck. Vehicles play by a separate rulebook, and it comes down to two things: how much you use the vehicle for business, and its gross vehicle weight rating (GVWR), printed on the sticker inside the driver’s door.

First, the business-use test. To use Section 179 or bonus depreciation on a vehicle, you have to use it more than 50% for business. If you use it 70% for work, only 70% of the cost counts. And if business use later drops to 50% or below during the recovery period, part of the deduction you already took gets added back to your income. Keep a mileage log from day one. It’s the proof the deduction stands on.

Under 6,000 lbs GVWR: you’re in “luxury auto” territory under Section 280F, no matter what the vehicle is or what it costs. For a vehicle placed in service in 2026, first-year depreciation is capped at $20,300 with bonus depreciation ($12,300 without it), then $19,800 in year two, $11,900 in year three, and $7,160 a year after that. A $75,000 car on a lighter platform writes off barely faster than a $35,000 one.

6,001 to 14,000 lbs GVWR, classified as an SUV: Section 179 alone is capped at $32,000 for 2026. But bonus depreciation isn’t subject to that cap. It applies to whatever cost is left after the $32,000. So at the federal level, a $75,000 heavy SUV used 100% for business can generally still be fully written off in 2026: $32,000 through Section 179 and the remaining $43,000 through bonus depreciation.

Over 14,000 lbs, or a work setup that doesn’t count as an SUV (a pickup with a cargo bed at least 6 feet long that you can’t reach from the cab, a cargo van with no seating behind the driver, anything that seats more than nine behind the driver): none of the vehicle caps apply. It’s treated like any other business equipment under the general rules above.

So for 2026, the federal gap between a heavy SUV and a true work truck of the same price is small, since both can usually be fully written off in year one. Where the classification still really matters:

State taxes. Many states don’t follow federal bonus depreciation, and some have their own Section 179 rules. New York is a good example: it adds back federal bonus depreciation and has you depreciate the regular way instead, and it doesn’t allow Section 179 at all on SUVs over 6,000 lbs. A heavy SUV that’s fully written off on your federal return can look very different on a New York return. California doesn’t allow bonus depreciation and caps Section 179 at $25,000.
If you skip bonus depreciation on purpose. You can elect out of it if you’d rather spread deductions across future years (more on why below). Do that, and the $32,000 SUV cap becomes your real ceiling.
Under 6,000 lbs is a hard wall either way. If the tax write-off matters to the purchase, check the GVWR number on the door sticker before you sign anything, not the “SUV vs. truck” label in the ad.

One more vehicle trap: if you take Section 179, bonus, or regular accelerated depreciation on a vehicle, you can’t switch that vehicle to the standard mileage rate later. The mileage deduction guide walks through picking between the two methods, and it’s worth reading before your first tax year with a new truck.

When Taking the Full Deduction Right Away Isn’t the Smart Move

Full expensing in year one feels like the obvious choice, and often it is. But a dollar of deduction isn’t worth the same in every year. It’s worth whatever your tax rate is that year, which is why timing deserves a second thought.

A slow year, when income is already low, is often the wrong year to burn a big deduction. A deduction taken in the 12% bracket saves less than the same deduction taken in the 22% or 24% bracket. If a major purchase can reasonably wait, or you have some control over when the equipment is “placed in service” (the date it’s ready and available for use, which controls the deduction year, not the purchase date), moving it into a stronger year can be worth more than the immediate write-off.

This is also where electing out of bonus depreciation becomes a real option. Bonus depreciation applies automatically unless you opt out, by class of property, on your return. Businesses with seasonal or lumpy income sometimes do this on purpose: they take Section 179 on the assets they choose and skip bonus depreciation on the rest, letting regular depreciation spread the deduction over the next several years instead of front-loading it into a year where it’s worth less.

If you’re an S-Corp owner, the timing question also interacts with your salary and QBI deduction. The S-Corp vs LLC guide covers how that side works.

The Bill Nobody Mentions: Depreciation Recapture

This is the part that catches people off guard, sometimes years after they’ve forgotten the original purchase. Depreciation is mostly a timing benefit, not free money. When you sell or trade in equipment you’ve depreciated, any amount you get above its remaining tax basis (what you paid minus the depreciation you’ve already taken) is generally recaptured. That means it’s taxed as ordinary income in the year of the sale, up to the total depreciation you claimed.

Trade-ins count too. Since 2018, swapping equipment or vehicles no longer qualifies for tax-free like-kind exchange treatment, so a trade-in is treated as a sale for tax purposes.

Here’s what that looks like. Say a plumbing business buys a $60,000 cargo van and writes off the whole thing through Section 179 and bonus depreciation, so its tax basis drops to $0. Three years later, the van gets traded in for $35,000 toward a newer one. Since the basis is $0, the full $35,000 is recapture, taxed as ordinary income that year. In the 22% bracket, that’s about $7,700 of federal income tax on a trade-in that put no cash in your pocket. The good news is that recapture from selling equipment generally isn’t hit with self-employment tax on top.

It’s not a penalty or a mistake. It’s the other half of the deal you made when you took the full deduction upfront. The problem is that a lot of people don’t see it coming. If you know a sale or trade-in is coming, build it into your quarterly estimated tax planning for that year. The quarterly tax estimator can show how a recapture year shifts what you owe. If the newer equipment is placed in service the same year, its own write-off can offset much of the recapture.

Regular Depreciation: What Happens If You Don’t Take the Full Write-Off

If you don’t elect Section 179 and opt out of bonus depreciation, or the asset doesn’t qualify for either, the cost gets spread out under MACRS, the IRS’s standard depreciation system. Cars, light trucks, and computers fall into a 5-year recovery period. Most other business machinery and equipment, office furniture included, falls into 7 years. MACRS isn’t a flat even split either. It puts more of the deduction into the early years using IRS percentage tables, so it still recovers cost faster than straight-line, just nowhere near as fast as writing off the whole thing in year one. Whatever you choose, keep the receipts, placed-in-service dates, and depreciation records for every asset. Clean business bookkeeping makes this a lot easier.

Bottom Line

For most tradespeople, the default still makes sense: expense small items under the $2,500 safe harbor, use Section 179 on the assets you want control over, let bonus depreciation cover the rest, and write it all off in year one.

Slow down in three situations: a low-income year, a vehicle purchase where the GVWR sticker and your business-use percentage matter more than the marketing, and any purchase where you can already see the trade-in coming. None of this changes the financing decision itself. It changes how you handle the tax side once the equipment is yours. If you’re pricing out a whole shop, the auto repair shop startup cost calculator lays out the big equipment lines.

One more place this shows up later: if a house is in your future, a mortgage lender qualifies you on net income after these same deductions, not gross revenue. Depreciation can often be added back into that number, since it never actually left your bank account. Mortgage preapproval covers how that works and what else changes when you’re self-employed.

Frequently Asked Questions

Section 179 is limited to your taxable income from active business for the year, including W-2 wages, and can’t create a loss, though unused amounts carry forward with no expiration. Bonus depreciation has no income limit and can create or deepen a business loss. In profitable years they’re usually used together. In a slow year, bonus depreciation is the one that still works.

Less than it used to, at least federally. A heavy SUV (6,001 to 14,000 lbs GVWR) is capped at $32,000 under Section 179 for 2026, but 100% bonus depreciation generally covers the rest, so both can often be fully written off in year one if used more than 50% for business. State returns can differ a lot. New York, for example, disallows Section 179 on SUVs over 6,000 lbs and adds back federal bonus depreciation.

More than 50% to use Section 179 or bonus depreciation, and only the business percentage of the cost counts. If business use later drops to 50% or less during the recovery period, part of the earlier deduction gets added back to your income. A mileage log is what proves your percentage.

Yes. A deduction is worth more in a year you’re in a higher tax bracket than in a low-income year. If this year is unusually slow, or you expect much more income soon, electing out of bonus depreciation on a given class of property and letting regular depreciation spread the deduction across future years can be worth more than front-loading it now.

When you sell or trade in equipment you’ve depreciated, any amount you get above its remaining tax basis is generally taxed as ordinary income that year, up to the depreciation you claimed. Trade-ins count as sales. If you fully wrote off a $60,000 van and trade it in for $35,000, the whole $35,000 is recaptured, about $7,700 of federal tax in the 22% bracket.

Yes, but it falls under the luxury auto limits of Section 280F. For a vehicle placed in service in 2026, total first-year depreciation is capped at $20,300 with bonus depreciation ($12,300 without), combining Section 179 and bonus, with the rest spread over later years ($19,800, then $11,900, then $7,160 a year).

Often not. Under the IRS de minimis safe harbor, most small businesses can expense items costing $2,500 or less per item or invoice as a regular business expense, if they make the election on their return each year.

The cost is spread out under MACRS instead, typically 5 years for cars, light trucks, and computers, or 7 years for most other business equipment and furniture. It puts more of the deduction into earlier years than a flat straight-line split would, just far more gradually than writing off the full cost in year one.
