Listed property depreciation rules turn on a single number: your business use percentage. Use the asset more than 50% for business, and you get accelerated depreciation under MACRS, Section 179 expensing, and bonus depreciation. Hit 50% or below, and you’re forced onto straight-line depreciation under the Alternative Depreciation System, with no shortcuts available. And if your business use later drops below that line after you’ve already claimed accelerated deductions, the IRS claws the excess back as ordinary income. That threshold, set by IRC Section 280F, is the hinge the entire regime swings on.
What Qualifies as Listed Property
Listed property is a category the IRS singles out because these assets lend themselves as easily to personal use as to business. IRC Section 280F(d)(4) defines four groups:
- Passenger automobiles: four-wheeled vehicles made primarily for public roads and rated at 6,000 pounds unloaded gross vehicle weight or less. Trucks and vans use gross vehicle weight instead.
- Other transportation property, such as motorcycles and similar means of getting from place to place.
- Entertainment and recreation property, including boats and airplanes.
- Any additional property types designated by Treasury regulations.
Property used almost entirely in the business of transporting people or goods for hire is not treated as listed property, which is why taxis, ambulances, and full-time delivery trucks depreciate under ordinary rules.1Office of the Law Revision Counsel. 26 USC 280F – Limitation on Depreciation for Luxury Automobiles
One boundary worth flagging: computers and peripheral equipment are no longer listed property. The Tax Cuts and Jobs Act pulled them out of the definition starting in 2018, so a laptop you carry between home and office depreciates under ordinary rules with no 50% threshold to clear.2Internal Revenue Service. Tax Cuts and Jobs Act: A Comparison for Businesses
How the 50% Business Use Test Works
The year you place the property in service determines which depreciation track you’re on. If business use exceeds 50% that first year, the property is “predominantly used in a qualified business use,” and every accelerated tool in the code is available. Fall short, and you’re locked into the slower method for the life of the asset.1Office of the Law Revision Counsel. 26 USC 280F – Limitation on Depreciation for Luxury Automobiles
For vehicles, the percentage is business miles divided by total miles for the year. For other listed property, it’s the proportion of time or usage devoted to business. Whichever depreciation method you qualify for, you multiply the full amount by your business use percentage to get the actual deduction.
Qualified business use excludes investment use. If you drive 30% for your consulting business, 25% managing rental properties, and 45% personally, only the 30% counts toward the 50% threshold. The investment portion still generates some depreciation, but it cannot push you over the line.
Depreciation Above the 50% Threshold
Clearing the threshold opens three cost recovery options.
MACRS General Depreciation System
Listed property used predominantly for business qualifies for the General Depreciation System, which typically uses the 200% declining balance method. Most listed property falls into the five-year class, meaning you recover the cost over six calendar years using the half-year convention in the first and last years. This front-loads deductions heavily compared to straight-line.
Section 179 Expensing
Section 179 lets you deduct the entire cost of qualifying property in the year it’s placed in service. For 2026, the maximum Section 179 deduction is $2,560,000, with a phase-out beginning when total qualifying property placed in service exceeds $4,090,000. The deduction cannot exceed taxable income from active business operations.
For passenger automobiles, the Section 179 deduction is still capped by the luxury auto limits below. Heavy SUVs and trucks rated over 6,000 pounds gross vehicle weight escape the luxury caps but face a separate $32,000 Section 179 limit.
Bonus Depreciation
Bonus depreciation allows an immediate first-year write-off of a percentage of the asset’s cost after any Section 179 deduction. For property placed in service in 2026, the One Big Beautiful Bill Act restored 100% bonus depreciation, reversing the phase-down originally set under the Tax Cuts and Jobs Act. For passenger automobiles, bonus depreciation adds $8,000 to the first-year luxury cap.3Internal Revenue Service. Revenue Procedure 2026-15
2026 Luxury Auto Caps
Passenger automobiles face annual dollar ceilings that override whatever your calculated deduction would otherwise be. The caps apply to the business-use portion of depreciation and restrict what you can claim even at 100% business use.
For passenger automobiles placed in service in 2026 with bonus depreciation:
- Year 1: $20,300
- Year 2: $19,800
- Year 3: $11,900
- Each succeeding year: $7,160
Without bonus depreciation (or if you elect out), the Year 1 cap drops to $12,300; the later years match. The $8,000 gap in Year 1 is the bonus depreciation add-on under Section 168(k)(2)(F)(i).3Internal Revenue Service. Revenue Procedure 2026-15
These caps bite hardest on expensive vehicles. Buy a $60,000 car and use it 80% for business, and your first-year depreciation is capped at $20,300 times 80%, or $16,240, rather than the much larger figure MACRS or bonus depreciation would otherwise generate. You keep claiming $7,160 per year (times business use) after year three until the full basis is recovered, which can stretch well past the standard five-year period.
Depreciation at 50% or Below
Missing the threshold shuts the door on every accelerated method. No Section 179, no bonus depreciation, no 200% declining balance. You must depreciate the asset under the Alternative Depreciation System using the straight-line method.1Office of the Law Revision Counsel. 26 USC 280F – Limitation on Depreciation for Luxury Automobiles
ADS spreads the cost evenly over the recovery period. For passenger automobiles, that recovery period is five years, the same number as under GDS, but the switch from 200% declining balance to straight-line means much smaller deductions in the early years.4Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System
For personal property with no assigned class life, the ADS recovery period defaults to 12 years, which can delay cost recovery even further for unusual assets. The annual deduction is still multiplied by your actual business use percentage.
The choice is set by the first year’s business use percentage and cannot be changed later. A taxpayer who barely misses at 49% cannot switch to accelerated methods even if business use climbs to 90% in subsequent years. ADS sticks for the life of the asset.
Recapture When Business Use Drops
The 50% test isn’t a one-time check. If you claimed accelerated depreciation in the year the property was placed in service and business use later falls to 50% or below, the IRS claws back the excess through recapture.1Office of the Law Revision Counsel. 26 USC 280F – Limitation on Depreciation for Luxury Automobiles
Excess depreciation is the difference between what you actually claimed under the accelerated method (including any Section 179 and bonus depreciation) and what you would have claimed if you had used ADS straight-line from the start. That full difference becomes ordinary income in the year business use drops below the threshold, reported on Form 4797.5Internal Revenue Service. About Form 4797, Sales of Business Property
How the Math Works
Say you place a $50,000 listed property in service in Year 1 at 70% business use, qualifying for accelerated methods. Between Section 179, bonus depreciation, and MACRS, you claim $20,000 in depreciation that first year. In Year 2, business use drops to 45%.
Recalculate what you would have deducted in Year 1 under ADS straight-line at the same 70% business use. If that figure is $7,000, the excess depreciation is $13,000. You report $13,000 as ordinary income on your Year 2 return.
The recapture calculation captures only the method difference, applied at the original 70% rate. Going forward, you depreciate the remaining basis using ADS straight-line at your current (now 45%) business use percentage. The adjusted basis after recapture is reduced by the depreciation that would have been allowable under ADS, not the amount you actually took, which prevents double-counting the excess you’ve already given back.
Recapture is mandatory regardless of whether your business had a profit or loss that year, and the income is taxed at ordinary rates. The rule is deliberately punitive, meant to discourage large upfront deductions on property that quickly shifts to personal use.
Employees Using Their Own Listed Property
Employees face an extra hurdle. Use of listed property counts as qualified business use only if it is for the convenience of the employer and required as a condition of employment. Voluntary use of a personal vehicle for work errands, even if it benefits the employer, doesn’t clear the bar.6eCFR. 26 CFR 1.280F-6 – Special Rules and Definitions
“Required as a condition of employment” means you genuinely cannot perform your job duties without the property. An employer’s written policy is a starting point, but the IRS examines whether the requirement has real substance and whether alternatives exist. Failing this rule means the employee’s use is not qualified business use at all. An employee driving 60% for work whose employer doesn’t require it has 0% qualified business use and is stuck with ADS straight-line from day one.
Leased Listed Property
Leasing doesn’t sidestep Section 280F. The statute imposes an equivalent limitation on lessees through a lease inclusion amount. Rather than capping depreciation, the IRS requires you to add an amount to gross income each year of the lease, which reduces the net benefit of your lease payment deductions.1Office of the Law Revision Counsel. 26 USC 280F – Limitation on Depreciation for Luxury Automobiles
The inclusion amount comes from IRS tables published for each calendar year. For leases beginning in 2026, Revenue Procedure 2026-15 provides Table 3, which gives dollar amounts based on the fair market value of the vehicle. The result: the net tax benefit of deducting lease payments roughly matches what an owner’s depreciation would be after the 280F caps. Recapture rules similar to those for owned property also apply if business use falls to 50% or below.3Internal Revenue Service. Revenue Procedure 2026-15
Recordkeeping and Reporting
Substantiation is where most taxpayers get tripped up. IRC Section 274(d) disallows any deduction for listed property unless the taxpayer substantiates the amount, time and place, business purpose, and business relationship through adequate records or corroborating evidence.7Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses
In practice, that means a contemporaneous log, created at or near the time of each use, not reconstructed from memory at tax time. For vehicles, each entry should record the date, mileage, destination, and specific business purpose. “Client meeting” is thin; “meeting with Jane Smith at Acme Corp to discuss Q3 contract” is closer to what survives an audit.
The business use percentage gets reported on Part V of Form 4562, which is dedicated to listed property. Part V must be completed before the rest of the form, and listed property cannot be reported in Parts II or III.8Internal Revenue Service. Form 4562 – Depreciation and Amortization
Commuting Versus Business Miles
The distinction trips up many vehicle owners. Your daily drive from home to a regular workplace is a personal commute and never counts as business mileage, no matter how far you drive. Travel between two work locations during the day is deductible business mileage.9Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses
One exception matters: if your home office qualifies as your principal place of business, trips from home to any other work location in the same trade or business are deductible, even if that location is permanent. Without a qualifying home office, travel from home to a temporary work site is deductible only if you have a regular office elsewhere. Miscategorizing these trips inflates your business use percentage, and if an audit corrects the numbers, you can be pushed below 50% retroactively, triggering recapture on years of accelerated depreciation.9Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses
When Records Fail
Inadequate records don’t just shave your deduction; they can wipe it out entirely. The IRS can disallow depreciation, Section 179, bonus depreciation, and all related operating expenses including fuel, maintenance, insurance, and interest. Credit card statements and bank records alone won’t do the job. They show you spent money, but they don’t establish the business purpose of each trip. The record must connect the expense to a business function explicitly. A perfectly calculated depreciation schedule means nothing if the log behind it can’t support the business use percentage.
