Capital Expenses Examples: Types, Deductions, and Safe Harbors

Capital expenses examples include buying a delivery truck, a new HVAC system, a patent, a commercial building, or the goodwill you acquire when purchasing another business. What ties them together is simple: each creates or improves an asset that will keep producing value for your business beyond the current tax year. Because the benefit stretches across multiple years, the tax code will not let you deduct the full cost in the year you spend the money. You capitalize the cost, then recover it gradually through depreciation or amortization, unless a specific provision lets you write it off sooner.¹

What Makes an Expense Capital

Operating expenses are the routine costs of running the business: rent, utilities, office supplies, payroll. You use them up inside the same year you pay them, and they are fully deductible on that year’s return.

A capital expense behaves differently. It buys or builds something with a useful life measured in years, so the cost sits on your balance sheet as an asset and moves onto your tax return in pieces over time.

The practical test is one question: does the spending maintain what you already have, or does it create something new or materially better? Replacing a broken light switch maintains what exists. Rewiring the entire building creates something materially better. That line is where most small-business tax disputes live.

Examples of Capital Expenses

Tangible Property

Physical assets bought for business use are the clearest cases. Machinery, vehicles, buildings, furniture, and computers all get capitalized. The full purchase price, plus any costs to get the asset ready for use, becomes part of its tax basis.²

Land is a special case. It is always capitalized, but it can never be depreciated, because the IRS treats it as having an indefinite useful life. When you buy property that includes both land and a building, you allocate the price between them and only the building portion is depreciable.³

Intangible Property

Some capital assets have no physical form. Patents, copyrights, trademarks, customer lists, and goodwill acquired as part of buying a business all count. These are recovered through amortization rather than depreciation, generally on a straight-line basis over 15 years under Section 197. The 15-year clock starts in the month you acquire the intangible.⁴

Costs of Acquiring the Asset

Money spent just to close on a capital asset gets capitalized too. Legal fees, appraisal fees, title insurance, recording fees, and transportation charges add to the asset’s basis rather than being deducted right away. Pay $3,000 in legal fees to buy a warehouse, and that $3,000 becomes part of the warehouse’s depreciable cost.²

Repairs vs. Improvements

This is the classification that draws the most IRS scrutiny. A repair keeps property in its current operating condition and is deductible immediately. An improvement makes the property materially better, restores it to like-new condition, or adapts it to a new use, and must be capitalized.¹

The IRS evaluates improvements at the level of the “unit of property,” and for a building it does not treat the building as a single unit. It looks separately at the building structure and at each major system: plumbing, electrical, HVAC, elevators, escalators, fire protection and alarm, gas distribution, and security. Swapping out one component of a system may be a repair. Overhauling the whole system is almost certainly a capital improvement.⁵

Some concrete examples:

Repair, deductible now: patching a section of roof, fixing a broken window, replacing a burned-out motor, repainting the building exterior.
Improvement, must be capitalized: replacing the entire roof structure, installing a new HVAC system, adding a security system, constructing an addition.

When work is part of a larger restoration, such as gutting and renovating a whole floor, the full project cost gets capitalized even if individual tasks inside it would have qualified as repairs on their own.

How You Deduct Capital Expenses Over Time

Once you capitalize an expense, you recover the cost through annual deductions over the asset’s recovery period. Tangible assets use depreciation. Intangibles use amortization.

MACRS for Tangible Property

The Modified Accelerated Cost Recovery System is the default depreciation method for most tangible business property placed in service after 1986. Each type of property has an assigned recovery period.⁶

The most common MACRS classes:

5-year property: automobiles, light trucks, computers, office machinery like copiers and calculators, property used in research.
7-year property: office furniture and fixtures such as desks, filing cabinets, and safes, plus any property that has no other designated class life. This is the default bucket, so a lot of general-purpose equipment lands here.
27.5-year property: residential rental buildings.
39-year property: nonresidential (commercial) buildings.

A common mistake is assuming all equipment depreciates over five years. Most office furniture and general-purpose equipment without a specific IRS classification is seven-year property. Depreciation is reported on Form 4562.⁷

Section 197 Amortization for Intangibles

Purchased intangibles including goodwill, workforce-in-place value, customer-based intangibles, and covenants not to compete are amortized straight-line over 15 years, with the deduction starting in the month of acquisition rather than the year.⁸

When You Can Deduct It All in Year One

Waiting years to recover the cost of an asset is often unattractive, and two provisions let you accelerate the write-off, in many cases to a full year-one deduction.

Section 179 Expensing

Section 179 lets you elect to deduct the full cost of qualifying property in the year it is placed in service. For 2026, the maximum deduction is $2,560,000, phasing out dollar-for-dollar once total Section 179 property placed in service that year passes $4,090,000. The phaseout aims the provision at small and mid-sized businesses.⁹

Qualifying property includes tangible personal property such as machinery and equipment, off-the-shelf computer software, and certain real property improvements to nonresidential buildings. Eligible improvements include roofs, HVAC, fire protection and alarm systems, and security systems. Qualified improvement property, which is improvements to the interior of a nonresidential building, also qualifies.¹⁰

Sport utility vehicles have their own ceiling: only $32,000 of cost can be expensed under Section 179 for 2026, no matter the vehicle’s total price.⁹

Bonus Depreciation

Bonus depreciation, formally the additional first-year depreciation deduction, works alongside Section 179. Under the One Big Beautiful Bill Act, 100% bonus depreciation was permanently restored for qualifying property acquired after January 19, 2025. The prior-law phasedown that would have dropped the rate to 20% in 2026 no longer applies; the rate is permanently 100%.¹¹

Bonus depreciation has no dollar cap, which makes it more powerful than Section 179 for large purchases. It applies to new and used property with a MACRS recovery period of 20 years or less, so most equipment, vehicles, and qualified improvement property qualify. Commercial buildings themselves generally do not.

Safe Harbors That Skip Capitalization

The IRS offers safe harbors that let you avoid the capitalization analysis for certain spending. Each is an election, meaning you have to affirmatively use it.

De Minimis Safe Harbor

This election lets you immediately expense low-cost items you would otherwise capitalize. The threshold depends on whether you have an applicable financial statement, which is typically an audited financial statement:

With an AFS: up to $5,000 per invoice or per item.
Without an AFS: up to $2,500 per invoice or per item.

With an AFS you need a written accounting procedure in place at the start of the tax year. Without one, no written policy is required, but you must consistently expense these amounts on your books under a policy that existed at the start of the year.⁵

The de minimis safe harbor does not apply to inventory or land, but it clears smaller tools, equipment, and supplies off your depreciation schedules.

Routine Maintenance Safe Harbor

This one covers recurring maintenance you expect to perform to keep property in ordinary operating condition. If the work qualifies, it is deductible now even if it might otherwise look like an improvement.⁵

Buildings and building systems: you must reasonably expect to perform the maintenance more than once during the 10-year period beginning when the property is placed in service.
Other property: you must reasonably expect to perform it more than once during the property’s MACRS class life.

The safe harbor does not cover betterments. If the work upgrades property beyond its original condition, it is an improvement no matter how routine it seems. It does cover certain restorations, including replacing a major component of a unit of property, as long as the other requirements are met.

Research and Software Development Costs

Treatment of research and experimental costs has shifted. A new Section 174A, enacted through the One Big Beautiful Bill Act, allows businesses to immediately deduct domestic research and experimental expenditures for tax years beginning after December 31, 2024. That reversed the mandatory five-year capitalization requirement that had been in effect since 2022. Software development costs paid or incurred in connection with domestic activities also qualify for immediate expensing under this provision.

Foreign research is treated differently. Costs attributable to research conducted outside the United States must still be capitalized and amortized over 15 years, starting at the midpoint of the tax year in which they are paid or incurred.¹²

If your business does both, allocate carefully. Misclassifying foreign research as domestic to grab the immediate deduction is exactly the sort of error that draws audit attention.

What It Costs to Get This Wrong

Treating a capital expense as an operating expense inflates your current-year deductions and understates taxable income. If the IRS finds the error, you face two layers of cost on top of the extra tax.

First, interest on the underpayment, which compounds daily. The IRS adjusts the rate quarterly. For the most recent 2026 quarter, the rate is 6% per year for most taxpayers.¹³

Second, accuracy-related penalties. The standard penalty is 20% of the underpayment attributable to negligence or a substantial understatement of income. For most businesses, a substantial understatement means the understatement exceeds the greater of 10% of the correct tax or $5,000. If the misclassification involves a gross valuation misstatement, the penalty doubles to 40%.¹⁴

Penalties can be waived for reasonable cause and good faith, but “my bookkeeper said it was a repair” rarely clears that bar. Contemporaneous documentation of why you classified something as a repair rather than an improvement is the single strongest audit defense. Notes written at the time carry far more weight than an explanation drafted after an IRS notice arrives.
