Personal Property Depreciation: MACRS, Section 179, and Bonus Rules

Personal property depreciation is how you deduct the cost of business equipment, vehicles, furniture, and other tangible movable assets across several tax years instead of writing off the full price the year you buy them. For assets placed in service in 2026, you have three main tools: regular MACRS depreciation spread over a set recovery period, a Section 179 election of up to $2,560,000, and 100% bonus depreciation, which the One Big Beautiful Bill Act restored in mid-2025. Which one fits depends on the asset, how much you paid, how you use it, and when you expect to sell.

One boundary to clear up first: “personal property” in tax law does not mean personal belongings. It means tangible property that isn’t real estate. Your home television and family car aren’t depreciable; a laptop, delivery van, or shop machine used in your business is. Land is never depreciable because it doesn’t wear out, and buildings follow a separate set of rules.¹

What Qualifies for Depreciation

Internal Revenue Code Section 167 allows depreciation only on property used in a trade or business or held to produce income.² Three conditions have to line up:

You own the asset. Leased equipment generally doesn’t qualify unless the lease functions as a conditional sales contract that transfers ownership to you.¹
You use it in your business or income-producing activity.
Its useful life extends beyond one year. Anything you consume within twelve months, like office supplies or printer ink, is a current-year expense instead.

When You Can Skip Depreciation Entirely

Before setting up a depreciation schedule, check the de minimis safe harbor. It lets you deduct the full cost of low-dollar tangible property in the year of purchase without capitalizing it. Businesses with an applicable financial statement (an audited statement, for example) can expense items costing up to $5,000 per invoice. Without one, the cap is $2,500 per invoice.³

The election is annual and covers every qualifying purchase you make that year. To claim it, attach a statement titled “Section 1.263(a)-1(f) de minimis safe harbor election” to your timely filed return with your name, address, taxpayer identification number, and a declaration that you’re making the election.³ For a sole proprietor buying an $1,800 laptop, this is far simpler than a five-year depreciation schedule.

Cost Basis and Placed-in-Service Date

For anything that does need to be depreciated, the calculation starts with cost basis: the purchase price plus everything you spent to get the asset operational. That includes sales tax, freight, and installation. A $10,000 machine with $500 of delivery and $1,000 of setup has a depreciable basis of $11,500.⁴ Keep every receipt; the IRS expects you to substantiate each piece.

You also need to pin down the “placed in service” date, which isn’t the same as the purchase or delivery date. Under Treasury regulations, property is placed in service when it’s in a condition of readiness and availability for its assigned function, whether or not anyone actually uses it that day. An installed machine sitting idle on your factory floor counts.¹ This date decides which tax year you start depreciating and which convention applies.

Hold your records longer than feels necessary. The IRS says you must keep depreciation records until the statute of limitations expires for the year you dispose of the asset, not the year you bought it.⁵ For a seven-year asset you sell in year eight, that’s roughly eleven years of paperwork.

Recovery Periods

Every depreciable asset falls into a class that dictates how many years you spread the deduction. Publication 946’s Table of Class Lives is the reference. The classes you’ll run into most often for personal property:

3-year property: certain manufacturing tools, racehorses over two years old, and over-the-road tractor units.
5-year property: automobiles, light trucks, computers, printers, copiers, and certain technological equipment.⁶
7-year property: office furniture, fixtures, filing cabinets, and most machinery not assigned to a shorter class.¹

Classifying an asset in the wrong class accelerates or delays the deduction and, if caught, invites disallowance and penalties. When you’re unsure, look up the specific asset in Publication 946 rather than guessing.

How MACRS Works

Nearly all business personal property placed in service after 1986 is depreciated under the Modified Accelerated Cost Recovery System. Within MACRS, the General Depreciation System is the default and produces the largest early deductions. The Alternative Depreciation System uses longer periods and straight-line depreciation, and it’s required only in narrow situations, such as property used predominantly outside the United States.¹

Under GDS, 3-, 5-, and 7-year classes use the 200% declining balance method. The annual rate is 200% divided by the recovery period, applied to the remaining adjusted basis each year. For five-year property that’s 40% per year, front-loading the deduction. The rules require you to switch to straight-line in the first year straight-line produces an equal or larger deduction. In practice, most taxpayers skip the math and use the pre-calculated percentage tables in Publication 946: for five-year property under the half-year convention, that’s 20% in year one, 32% in year two, 19.2% in year three, and declining amounts through year six.

Half-Year vs. Mid-Quarter Conventions

Conventions decide how much depreciation you get in the first and last years. The half-year convention is the default and treats every asset as placed in service at the year’s midpoint, giving you half a year in year one and half in the final year.¹

The mid-quarter convention takes over when more than 40% of your total depreciable purchases for the year are placed in service in the last three months.⁷ Each asset then gets treated as placed in service at the midpoint of the quarter it actually entered use. If you’re planning a big fourth-quarter purchase, check whether it will trip the 40% threshold, because it changes the first-year depreciation on everything you bought that year.

Section 179: Immediate Expensing

Section 179 lets you deduct the entire cost of qualifying equipment in the year you place it in service. For tax years beginning in 2026, the maximum deduction is $2,560,000, and it phases out dollar-for-dollar once total qualifying purchases exceed $4,090,000.⁸

Two limits catch people off guard. First, the deduction can’t exceed your taxable income from the active conduct of a trade or business for the year; any excess carries forward. Second, you claim it on Part I of Form 4562, and it’s an election, not automatic.⁹

Bonus Depreciation Is Back to 100%

Bonus depreciation, formally the additional first-year depreciation deduction under Section 168(k), lets you deduct a percentage of a qualifying asset’s cost immediately, on top of any Section 179 deduction and before regular MACRS begins.¹

The rate had been phasing down: 80% in 2023, 60% in 2024, 40% in 2025. The One Big Beautiful Bill Act, signed in mid-2025, eliminated that phase-down and made 100% bonus depreciation permanent for qualifying property placed in service on or after January 20, 2025.⁶ For 2026 assets, you can deduct the full cost in year one using bonus depreciation alone.

Bonus depreciation has no dollar cap and no taxable-income limit, and it can create or increase a net operating loss. The trade-off: it applies automatically to all eligible property unless you affirmatively elect out, class by class, on your return. If you’d rather spread deductions across years for cash-flow or income-planning reasons, you have to opt out.

Vehicles and Other Listed Property

Certain assets prone to personal use get extra scrutiny under the “listed property” rules. Listed property includes passenger automobiles, property used for entertainment or recreation, and computers or peripherals unless used exclusively at a regular business establishment.

The 50% Business-Use Threshold

To claim Section 179 or bonus depreciation on listed property, your qualified business use must exceed 50% for the year. At 50% or less, you lose both accelerated options and must use straight-line depreciation over the ADS recovery period.¹⁰ If your business use starts above 50% and later drops to 50% or below, you have to recapture the excess depreciation as ordinary income in the year the use drops, reported on Form 4797.

2026 Passenger Automobile Caps

Even with 100% bonus depreciation available again, Section 280F caps the annual deduction on a passenger vehicle. For cars placed in service in 2026:¹¹

With bonus depreciation: $20,300 year one, $19,800 year two, $11,900 year three, $7,160 each year after until fully recovered.
Without bonus depreciation: $12,300 year one, $19,800 year two, $11,900 year three, $7,160 each subsequent year.

A $55,000 car will take many years to fully depreciate under either approach. Vehicles with a gross vehicle weight rating over 6,000 pounds, such as heavy SUVs and full-size trucks, are generally exempt from these caps, which is the origin of the “Section 179 SUV deduction” you sometimes hear about. That exemption has its own rules, but the annual caps above don’t apply.

Filing on Form 4562

All depreciation deductions run through IRS Form 4562, Depreciation and Amortization. Part I handles Section 179, Part II handles bonus depreciation, and later parts handle regular MACRS, listed property, and amortization.⁹ You enter cost basis, placed-in-service date, recovery period, method, and convention, and the form produces the total.

Form 4562 attaches to your main return. Sole proprietors file it with Form 1040 and carry the deduction to Schedule C. C corporations use Form 1120. Partnerships and S corporations report depreciation on their entity returns and pass it through on Schedule K-1.¹²

Recapture When You Sell

The tax benefit isn’t free. When you sell depreciated personal property at a gain, Section 1245 requires you to recapture the depreciation by treating part of the gain as ordinary income taxed at your regular rate, not the lower long-term capital gains rate.¹³

The recapture amount is the lesser of the total depreciation you claimed or the gain on sale. Say you bought equipment for $50,000, claimed $30,000 in depreciation (adjusted basis of $20,000), and sold it for $35,000. The gain is $15,000. Because that’s less than the $30,000 of depreciation, the whole $15,000 is ordinary income. Sell it for $55,000 instead and the first $30,000 of gain is ordinary income (matching total depreciation) while the remaining $5,000 is a Section 1231 gain, potentially eligible for long-term capital gains rates.¹³

Recapture goes on Part III of Form 4797, Sales of Business Property.¹⁴ This is the piece taxpayers most often miss. Aggressive first-year deductions through Section 179 or bonus depreciation maximize up-front savings, and they also maximize the ordinary income you’ll owe if you sell before the asset is worthless. Weigh the expected resale value against how much you expense immediately.

Penalties for Getting It Wrong

Overstating depreciation can trigger the accuracy-related penalty under Section 6662, which adds 20% to the underpaid tax when the IRS finds negligence, disregard of the rules, or a substantial understatement.¹⁵ Interest also runs on both the tax and the penalty from the original return due date until paid.

The common mistakes: putting an asset in a shorter recovery period than it belongs in, claiming Section 179 on property that doesn’t qualify, failing to reduce depreciation for the personal-use portion of a mixed-use asset, and skipping the recapture calculation when listed property use drops to 50% or below. Clean records of cost, placed-in-service dates, and business-use logs for listed property are the strongest defense if the IRS questions any of it.
