You bought a $58,000 SUV for your business, drove it mostly for work, and deducted the whole thing. Then an auditor asks for your mileage log, and you have nothing but a rough guess and a calendar with a few client names scribbled in it. That deduction is now gone — not reduced, gone — because the vehicle you depreciated is what the tax code calls listed property, and listed property plays by stricter rules than anything else on your depreciation schedule.
Listed property is the IRS's short list of assets that are easy to mix with personal life: cars, other transportation, entertainment equipment, and cameras and recording gear. Because the temptation to write off a personal car as a business expense is obvious, Congress built a separate regime around these assets — a business-use test, heightened recordkeeping, special dollar caps, and its own section of Form 4562. Here is how it works and how to stay on the right side of it.
What Counts as Listed Property
Section 280F(d)(4) defines five categories of listed property:
- Passenger automobiles. Any four-wheeled vehicle manufactured primarily for use on public streets and rated at 6,000 pounds or less of gross vehicle weight. Your sedan, crossover, and light SUV live here.
- Other property used as a means of transportation. Motorcycles, boats, and airplanes used in the business, for example.
- Property generally used for entertainment, recreation, or amusement. Think of a boat kept partly for client outings or a vacation condo used to entertain customers.
- Photographic, phonographic, communication, and video recording equipment. Cameras, lenses, video rigs, and recording gear used in a business where personal use is plausible.
- Computers and peripheral equipment. This category was removed from the list starting in 2018, as explained below, but you will still see it in older guidance.
Two categories were deliberately taken off the list because the rules had become silly in light of how people actually work. Cell phones were removed in 2010 — before that, every employee smartphone technically needed a call-by-call business-use log. Computers and peripheral equipment followed in 2018 under the Tax Cuts and Jobs Act, so a laptop no longer triggers the heightened substantiation rules or the over-50-percent test described below. Cameras and video gear, however, are still on the list, which matters a great deal to photographers, videographers, and content creators.
A few work vehicles are excepted from listed property entirely. Clearly marked police, fire, and emergency vehicles, ambulances and hearses used as such, qualified moving vans, trucks with a loaded gross vehicle weight over 14,000 pounds, bucket trucks, cement mixers, forklifts, delivery trucks with seating only for the driver, flatbed trucks, and a handful of other specialized vehicles are not listed property at all. If your vehicle is on the excepted list, none of the rules in this article apply to it — though you still need ordinary business records.
The Over-50-Percent Business-Use Test
The central gate is the predominant-use test: your qualified business use of the property must be more than 50 percent of its total use during the year. Get this wrong and the consequences cascade.
Qualified business use means use in your trade or business. Two exclusions trip people up:
- Investment use does not count. Driving to meet your stockbroker, check on rental properties you manage passively, or monitor investments is not qualified business use. Many mixed-use vehicles fail the test precisely because the owner counted investment miles as business miles.
- Commuting is never business use. Driving from home to your regular workplace is personal, even if you take business calls on the way. Only once your home qualifies as your principal place of business does driving from home to a work location start counting.
Pass the test — more than 50 percent qualified business use — and the asset gets normal treatment: Section 179 expensing, bonus depreciation, and regular MACRS depreciation are all available, subject to the luxury-vehicle dollar caps covered below.
Fail it — 50 percent or less — and three things happen at once. You cannot claim Section 179 expensing on the property at all. You cannot claim bonus depreciation. And you must depreciate the business portion using the Alternative Depreciation System: straight-line over a longer recovery period. For a vehicle, that means a slow straight-line write-off instead of an accelerated one.
Note that only the business percentage is ever depreciable either way. A car used 70 percent for business and 30 percent for personal trips yields depreciation on 70 percent of its basis, and the personal slice is simply lost — it does not carry forward or convert into anything else.
The Recapture Trap When Business Use Drops
The test is not a one-time hurdle at purchase; it applies every year you hold the property. If listed property met the more-than-50-percent test in the year you placed it in service but drops to 50 percent or less in any later year, Section 280F(b)(2) triggers recapture.
Recapture works like this: you must include in income the excess of the depreciation you actually claimed (including any Section 179 and bonus depreciation) over the depreciation you would have been allowed under straight-line ADS. You figure the amount on Form 4797, and from that year forward you depreciate the remaining basis straight-line.
This bites hardest when a business winds down or a vehicle quietly migrates to family duty. The photographer whose studio work slows and whose camera rig becomes mostly a hobby camera, or the consultant who retires the business car to school-run duty in year three, owes recapture in the year business use slipped — even though nothing was sold and no cash changed hands. If your business use of an asset is fading, model the recapture before year-end so the tax bill does not surprise you.
Adequate Records: The Substantiation Rules That End Deductions
Here is the rule that costs taxpayers the most money: for listed property, Section 274(d) disallows any deduction unless it is substantiated by adequate records or by evidence sufficient to corroborate your statements. Courts have read this strictly. Estimates are not enough, and the judges-are-allowed-to-estimate doctrine that rescues some undocumented expenses does not apply here. A reconstructed log built at tax time from memory, with no underlying records, routinely fails.
For a vehicle, an adequate record establishes four elements for each business use:
- The amount — the mileage for each business trip, plus total mileage for the year so the business-use percentage can be computed.
- The time — the date of each use.
- The place or destination — where you went.
- The business purpose — the business reason for the trip, specific enough to show it was not personal.
Records must generally be made at or near the time of the expenditure or use, when you still have full present knowledge of the details. A log you update weekly counts as contemporaneous; a spreadsheet filled in the following April does not. That said, the format is up to you: a paper mileage book, a spreadsheet, or a GPS mileage-tracking app all qualify, and digital records are fully acceptable. What matters is completeness and timeliness, not the medium.
Two practical points make or break audits. First, record total mileage too — odometer readings at the start and end of the year let you compute the business-use percentage, and without them the percentage is just an assertion. Second, do not rely on a calendar or mapping history alone. Appointment books and location history can corroborate a log, but examiners generally do not accept them as the log itself.
The same adequate-records standard covers the other listed-property categories. If you deduct a $9,000 camera body against freelance income, be ready to show which shoots it worked and how often it shot family birthdays instead.
The Section 280F Luxury Limits on Passenger Automobiles
Even when a passenger automobile clears the 50-percent test and your records are airtight, Section 280F(a) caps the annual depreciation deduction in dollars. These "luxury" limits apply to every passenger automobile — the name is historical; a modest sedan is capped exactly like an expensive one. The IRS publishes inflation-adjusted figures each year in a revenue procedure. For vehicles placed in service in 2026, the caps are:
- Year 1: $20,300 if bonus depreciation applies, or $12,300 if it does not
- Year 2: $19,800
- Year 3: $11,900
- Each succeeding year: $7,160 until the vehicle is fully depreciated
Two things follow from this table. First, bonus depreciation no longer lets you write off a car in year one — the $8,000 bonus add-on is already baked into the $20,300 first-year cap, so a $58,000 sedan still takes many years to depreciate fully. Second, the caps are prorated by business use: a car driven 80 percent for business gets 80 percent of each year's cap.
Heavier vehicles escape these dollar caps. A truck or van with a gross vehicle weight rating over 6,000 pounds is still listed property — the 50-percent test and the mileage-log rules still apply — but the annual dollar limits do not. That is why the 6,000-pound threshold dominates year-end vehicle-buying advice. One caveat: sport-utility vehicles in that weight class face their own Section 179 ceiling of about $32,000 for 2026, indexed annually, while qualifying pickup trucks with a sufficiently long bed and vans modified for business use can take the full Section 179 deduction.
Leased passenger automobiles get parallel treatment through income-inclusion amounts that offset the lease deduction, so leasing does not sidestep the caps — it just computes them differently.
Reporting It on Form 4562
Listed property gets its own real estate on Form 4562, and the questions there are more probing than most filers expect:
- Part V, Section A details each listed property: the date placed in service, the business-use percentage, and the depreciation claimed. This is where your mileage log turns into numbers.
- Part V, Section B covers the use of vehicles directly: business miles, commuting miles, other personal miles, whether the vehicle was available for personal use during off-duty hours, whether another vehicle is available for personal use, and — the question that ends audits — whether you have evidence to support the business use claimed, and whether that evidence is written.
- Part V, Section C asks employers about fleet vehicles provided to employees.
Answering "no" to the written-evidence question while claiming vehicle depreciation is effectively inviting an adjustment. And if business use dropped to 50 percent or less, the recapture computation goes on Form 4797, as noted above.
Employer-provided vehicles add a payroll dimension: an employee's personal use of a company car is taxable wages unless the employee substantiates business use back to the employer. Businesses that hand over keys without a written policy and a mileage-reporting habit end up with W-2 errors on top of the depreciation problem.
Common Mistakes and How to Avoid Them
Claiming 100 percent business use without a second vehicle. A sole proprietor who owns one car and deducts it at 100 percent is claiming to never drive for groceries, medical appointments, or anything personal. Examiners know this, and the Form 4562 question about whether another vehicle is available for personal use is designed to surface it. Claim an honest percentage and keep the log that proves it.
Counting commuting and investment miles as business miles. Both are excluded from qualified business use. Scrub them from the business column before computing the percentage — finding out in an audit that the real number was 48 percent means ADS re-computation plus lost Section 179.
Deducting first and logging later. The log must be contemporaneous. Set up the tracking method the week the asset goes into service, not the week before the return is due. A mileage app that runs automatically beats a perfect system you abandon by February.
Forgetting the heavy-SUV Section 179 ceiling. Buyers who hear "over 6,000 pounds means no luxury cap" sometimes expense the entire $80,000 SUV in year one. The luxury caps are gone, but the SUV-specific Section 179 limit still applies — plan for the remainder to depreciate over time.
Letting business use drift below half without modeling recapture. Track the percentage annually for every listed asset still on the depreciation schedule. A mid-life dip to 50 percent or less creates taxable income with no accompanying cash, and it is far better to see it coming.
Keep Your Vehicle and Equipment Records Audit-Ready
Listed property rewards taxpayers who treat recordkeeping as part of the purchase: the mileage log started the week the car arrives, the shoot log that travels with the camera bag, the annual business-use percentage computed before the return is prepared. Each habit is small; together they are the difference between a deduction that survives contact with an examiner and one that evaporates.
Consistent books make those habits easier, because depreciation schedules, asset registers, and expense categories all draw from the same records.
