For MACRS depreciation, five-year property and seven-year property are two different recovery-period classes, and the difference matters because five-year property writes off faster. Cars, light trucks, computers, and research equipment sit in the five-year class. Office furniture, fixtures, and most business assets that don’t fit a shorter class sit in the seven-year class. On the same $50,000 purchase, five-year treatment produces a $20,000 first-full-year deduction using the 200% declining balance method, while seven-year treatment produces $14,285.
Which Assets Are 5-Year Property
The five-year class covers several of the most common capital purchases a business makes:
- Automobiles and light general-purpose trucks
- Computers and peripheral equipment, including printers and monitors
- Equipment used for research and experimentation
- Semiconductor manufacturing equipment (named specifically in the statute)
- New farm machinery and equipment placed in service after 2017, if the original use begins with the taxpayer
One recent shift: the One Big Beautiful Bill Act removed solar and wind energy property from the five-year class. Certain other energy property still qualifies, but solar panels and wind turbines purchased for business use no longer follow the old schedule.2Internal Revenue Service. Publication 946 – How To Depreciate Property
Which Assets Are 7-Year Property
The seven-year class is the catch-all. If you buy a tangible business asset and it doesn’t land in a shorter recovery period, it usually ends up here. Typical items include:
- Office furniture and fixtures: desks, filing cabinets, shelving
- Used farm machinery and equipment that doesn’t qualify for the five-year class
- Grain storage bins, fences, and paved barnyards
Assets bought on the same day can land in different classes. A laptop is five-year property; the desk it sits on is seven-year property. Each gets its own depreciation schedule.
How the Deductions Compare
Both classes use the 200% declining balance method under the General Depreciation System, then switch to straight-line in the year that produces a larger deduction. The first-year rate is simply 200% divided by the recovery period: 40% for five-year property, 28.57% for seven-year property.
Applied to a $50,000 asset in a full year of ownership, that’s a $20,000 deduction under the five-year class and a $14,285 deduction under the seven-year class. The gap narrows over time as the seven-year schedule catches up, and the total deduction is the same eventually. What differs is when you get it, and earlier deductions are worth more because they cut current tax and keep cash in the business.
The Half-Year Convention Cuts the First Year Down
You don’t actually get a full year of depreciation in year one. The half-year convention, the default for both classes, treats every asset as placed in service at the midpoint of the year regardless of the actual purchase date. First-year deductions are roughly half of the full-year rate.3eCFR. 26 CFR 1.168(d)-1 – Applicable Conventions Half-Year and Mid-Quarter Conventions
The mid-quarter convention applies instead when more than 40% of the year’s total depreciable property is placed in service during the last three months of the year. Each asset is then treated as placed in service at the midpoint of the quarter you actually acquired it, which prevents claiming a half-year of depreciation on a December purchase.3eCFR. 26 CFR 1.168(d)-1 – Applicable Conventions Half-Year and Mid-Quarter Conventions
When the Class Barely Matters: Section 179 and Bonus Depreciation
Two first-year elections can make the five-vs-seven distinction irrelevant for a given asset, because you deduct the whole cost immediately.
Section 179 lets you deduct the full purchase price of qualifying property in the year it’s placed in service.4Office of the Law Revision Counsel. 26 US Code 179 – Election to Expense Certain Depreciable Business Assets For tax years beginning in 2026, the maximum deduction is $2,560,000, and the deduction begins phasing out dollar-for-dollar once total qualifying property placed in service exceeds $4,090,000.2Internal Revenue Service. Publication 946 – How To Depreciate Property Both five-year and seven-year property qualify. The catch: the Section 179 deduction can’t exceed the business’s taxable income for the year, though unused amounts carry forward.
Bonus depreciation stacks on top. After any Section 179 deduction, bonus depreciation writes off an additional percentage of the remaining basis in the first year. The One Big Beautiful Bill Act permanently reinstated 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025.2Internal Revenue Service. Publication 946 – How To Depreciate Property Bonus depreciation has no annual dollar cap and can generate or deepen a net operating loss, which Section 179 cannot.
Whatever basis is left after these elections gets depreciated over the standard five-year or seven-year MACRS schedule.
Vehicles Come With a Catch
Vehicles are five-year property, but they’re also “listed property,” which brings an extra rule. If business use drops to 50% or below in any year during the recovery period, you lose the accelerated MACRS method for that asset. You switch to straight-line under the Alternative Depreciation System and may have to recapture the excess depreciation already claimed as ordinary income.
On a $60,000 vehicle depreciated at 200% declining balance, dropping below 50% business use in year three means the IRS treats the difference between what you deducted and what straight-line would have allowed as taxable income that year. Contemporaneous mileage logs separating business from personal use are what protect the deductions if the return is examined.
State Returns Often Don’t Follow Federal
The federal depreciation you claim doesn’t automatically carry over to your state return. A significant number of states have decoupled from federal bonus depreciation, so the 100% write-off may need to be added back on the state return and depreciated over the standard MACRS recovery period for state purposes. Some states also cap Section 179 below the federal limit. The practical effect is two parallel depreciation schedules for the same asset: one federal, one state. Check your state’s conformity rules before filing.
Records, Disposal, and Depreciation Recapture
Keep records for a depreciable asset until the statute of limitations closes for the tax year in which you dispose of it. That means purchase receipts, invoices, and depreciation schedules held for the full recovery period plus at least three years after you report the sale or disposition.5Internal Revenue Service. How Long Should I Keep Records?
When you sell five-year or seven-year property, any gain up to the amount of depreciation you previously deducted is recaptured as ordinary income rather than taxed at capital gains rates. Your depreciation records set the adjusted basis at the time of sale, which controls how much of the sale price is recaptured depreciation versus capital gain. Losing the records doesn’t erase the tax; it just makes the basis harder to prove.
