What Is Capital Equipment? Depreciation, MACRS, and Section 179

Capital equipment is the set of durable physical assets a business buys to produce goods, deliver services, or run its operations over many years, rather than to resell or consume right away. So what is capital equipment in practical terms? A machine, vehicle, server, or medical device that will last longer than a year, costs more than the company’s capitalization threshold, and helps generate revenue. Because it lasts, its cost doesn’t hit the income statement all at once. It sits on the balance sheet and is written off gradually through depreciation, which shapes both your financial statements and how quickly you recover the cost on your tax return.

The Three Tests an Asset Has to Meet

An asset generally qualifies as capital equipment when three things are true. It has a useful life of more than one year, which is the baseline the IRS uses for depreciable property.¹ Its cost exceeds the company’s internal capitalization threshold. And it plays a direct role in generating revenue, rather than being consumed quickly like office supplies or raw materials.

There is no single federal number for that threshold. Each company sets its own floor in an internal accounting policy. For small and mid-sized businesses, the floor commonly sits between $500 and $5,000; larger companies sometimes set it at $10,000 or more. The IRS backs this flexibility with its de minimis safe harbor: businesses with audited financial statements can expense items costing up to $5,000 each, and businesses without audited statements can expense items up to $2,500 each, without capitalizing them.² Anything above those amounts that lasts more than a year is almost certainly capital equipment.

What It Looks Like in Different Industries

The label covers a wide range of assets, but the pattern is the same: something durable that earns its keep over years.

Manufacturing: CNC machines, injection molding presses, conveyor systems, industrial robots
Healthcare: MRI scanners, CT machines, surgical lasers, patient monitoring systems
Construction: excavators, cranes, concrete mixers, bulldozers
Technology: server farms, network switches, data storage arrays
Transportation and logistics: commercial trucks, delivery vans, forklifts, fleet vehicles
Agriculture: tractors, combines, irrigation systems, grain storage facilities
Food service: commercial ovens, walk-in refrigerators, industrial dishwashers

Buildings and certain land improvements such as paved parking lots or fencing are capital assets too, though they run on different depreciation schedules than equipment. Land itself is never depreciable, because it doesn’t wear out or become obsolete.¹

How It Differs From Operating Expenses and Inventory

The line between capital equipment and an operating expense is lifespan and cost. Operating expenses are the routine, short-term costs of running a business: rent, utilities, wages, office supplies, minor repairs. Federal tax law allows a deduction for “all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.”³ Those hit the income statement in the period they occur.

Capital equipment is recorded on the balance sheet as an asset, and its cost is spread across multiple years through depreciation. A $400 office printer that lasts two years might fall under a de minimis threshold and be expensed right away. A $40,000 commercial printing press with a seven-year useful life gets capitalized and depreciated.

Inventory is a separate category again. Inventory is goods held for sale to customers; when sold, its cost flows through cost of goods sold. Capital equipment stays in the business. A bakery’s flour is inventory. Its industrial oven is capital equipment. Consumables like toner cartridges or safety gloves are neither, and are simply operating expenses.

Depreciation on the Books and Under MACRS

Once you classify something as capital equipment, its full cost goes on the balance sheet, then moves to the income statement gradually through depreciation. This keeps a single large purchase from distorting profit in the year you buy it.

Book Depreciation

For financial reporting, the two common approaches are straight-line and accelerated. Straight-line subtracts the asset’s estimated salvage value from its original cost, divides by expected years of use, and produces the same expense every period. Buy a $100,000 machine with a $10,000 salvage value and a 10-year life, and you record $9,000 a year.

Accelerated methods front-load the expense. Double-declining-balance, for instance, records a larger charge in the early years and less later. That often fits equipment that loses productivity or becomes obsolete quickly, like technology hardware. Useful life and salvage value are set when the asset is placed in service and should be reviewed periodically under generally accepted accounting principles.

Tax Depreciation Under MACRS

For federal tax, most business equipment is depreciated under the Modified Accelerated Cost Recovery System, which assigns each type of property to a recovery class.⁴ The main classes for equipment are:

5-year property: automobiles, trucks, buses, office machinery such as copiers and calculators, computers, and research equipment⁵
7-year property: office furniture and fixtures such as desks and safes, plus any property that doesn’t have an assigned class life and isn’t specifically placed in another category⁵
10-year property: vessels, barges, and single-purpose agricultural structures
15-year property: land improvements like fences, roads, sidewalks, and bridges⁵
27.5 or 39 years: residential rental buildings and nonresidential commercial buildings, respectively⁴

The seven-year default catches a lot. If you buy equipment and can’t find a specific class for it, it lands there automatically, which covers much general-purpose machinery.

Faster Write-Offs: Section 179 and Bonus Depreciation

Two provisions let businesses recover the cost of capital equipment far faster than standard MACRS, and can sharply reduce taxable income in the year of purchase.

Section 179

Section 179 lets you deduct the full cost of qualifying equipment in the year it’s placed in service, rather than spreading it over the MACRS period.¹ For tax years beginning in 2025, the maximum deduction is $2,500,000, and it phases out dollar-for-dollar once total equipment purchases for the year exceed $4,000,000.⁶ Both figures are adjusted annually for inflation. For 2026, the maximum deduction is approximately $2.56 million, with the phase-out starting around $4.09 million.

Eligible property includes tangible personal property like machinery, office equipment, and printing presses; off-the-shelf computer software; and certain qualified real property improvements such as roofs, HVAC systems, fire protection, and security systems installed in nonresidential buildings.⁵ One important limit: the Section 179 deduction cannot exceed your total taxable income from active business operations for the year. Any excess carries forward.

Bonus Depreciation

Bonus depreciation works alongside Section 179 and has no dollar cap. Under the One Big Beautiful Bill signed into law in 2025, 100% first-year bonus depreciation was permanently restored for qualifying property acquired and placed in service after January 19, 2025.⁷ For 2026 and beyond, a business can deduct the full cost of eligible new or used equipment in the first year.

Unlike Section 179, bonus depreciation is mandatory unless you affirmatively elect out. To spread depreciation over the standard MACRS period for a given class, you have to make that election on your return for the year the property is placed in service.¹ Both Section 179 and bonus depreciation are claimed on IRS Form 4562, filed with the business tax return.⁸

Repair or Capital Improvement

Once equipment is in service, later spending on it raises a judgment call: deductible repair, or capital improvement that has to be added to the asset’s basis and depreciated? The IRS uses three tests. If the spending results in a betterment, a restoration, or an adaptation of the property to a new use, it must be capitalized.²

A betterment fixes a pre-existing defect, physically enlarges the asset, or materially increases its capacity, productivity, or output. A restoration replaces a major component or substantial structural part, or returns equipment that has completely broken down to working condition. An adaptation converts the asset to a fundamentally different use than what you originally intended.²

Routine maintenance that keeps equipment in its current operating condition, such as lubricating a press, replacing worn belts, or cleaning filters, remains a deductible operating expense. The line between “replacing a worn belt” and “replacing a major component” is where disputes with the IRS tend to happen, so when the cost is close, document why the work was necessary and what it accomplished.

Selling or Scrapping Capital Equipment

When you sell, trade in, or scrap capital equipment, the transaction produces a gain or loss that has to be reported. The gain or loss equals what you receive minus the asset’s adjusted basis, which is the original cost less all depreciation claimed. The sale of depreciable business equipment is reported on IRS Form 4797.⁹

A loss is generally deductible. A gain is more complicated because of depreciation recapture under Section 1245: the portion of your gain attributable to depreciation you previously claimed is taxed as ordinary income, not at the lower capital gains rate.¹⁰

A quick example. You bought a machine for $80,000, claimed $50,000 in depreciation, and sold it for $60,000. Adjusted basis is $30,000, so the gain is $30,000. Because you previously deducted $50,000 in depreciation and the gain is smaller than that, the entire $30,000 is recaptured as ordinary income.

If you dispose of a building and the equipment inside it in a single transaction, allocate the sale price between them by fair market value and report each separately on Form 4797.⁹ Skipping that allocation is a common audit trigger.

State Sales Tax on Manufacturing Equipment

Many states fully or partially exempt capital equipment purchases from sales and use tax when the equipment is used directly in manufacturing or production. The specifics vary. Some states grant a broad exemption for any machinery used in the production process; others limit it to equipment playing a “direct” or “predominant” role in creating the finished product; a few offer no manufacturing exemption at all. If your business is buying expensive production equipment, check your state’s rule before the purchase. The exemption typically has to be claimed with paperwork given to the seller at the time of sale, not through a refund after the fact.
