Capital acquisition is the process of obtaining a long-term asset a business needs to operate or grow — equipment, buildings, vehicles, software, patents, and similar property that will produce value over multiple years. Because the benefit runs beyond the current period, the cost goes onto the balance sheet as an asset rather than into the income statement as an expense, and is written off gradually through depreciation (for tangible property) or amortization (for intangibles). How you fund the purchase, how you obtain the asset, and which tax elections you make in the first year all shape your reported earnings and your tax bill for years afterward.
How Businesses Fund the Purchase
Funding usually comes from debt, equity, or internal cash, and each carries a different cost.
Debt financing means borrowing through term loans, corporate bonds, or revolving credit. Interest on business debt is generally deductible, which lowers the after-tax cost of borrowing.1Office of the Law Revision Counsel. 26 U.S.C. 163 – Interest The deduction is not unlimited, though. Under Section 163(j), most businesses can deduct net interest expense only up to 30% of adjusted taxable income for the year, so heavy borrowing does not always translate into a proportionally larger write-off.
Equity financing raises money by selling ownership — common or preferred stock to outside investors, or reinvested retained earnings. There is no fixed repayment obligation, but new shareholders dilute existing owners and typically demand a higher return than lenders because they sit behind debt if the business fails. Retained earnings avoid both dilution and transaction costs and are the simplest source when cash is available.
Mezzanine financing sits between the two. Lenders accept a subordinate position behind senior debt in exchange for higher interest and, often, a right to convert to equity on default. Companies use it when the purchase price exceeds what senior lenders will cover but the owners want to limit equity given up. The cost is significant, so mezzanine capital tends to make sense only when the acquisition can produce a return well above the premium.
How the Asset Is Obtained
With funding in place, the next choice is how to actually get the asset: buy it, lease it, or build it.
Direct Purchase
Buying outright transfers full ownership. You control how the asset is used, modified, or eventually sold, and the full purchase cost goes on the balance sheet and is written off over time through depreciation. The trade-off is the upfront cash requirement.
Leasing
Leasing gives you the use of an asset for a set period without owning it. Under ASC 842, both operating and finance leases must be recorded on the balance sheet as a right-of-use asset with a matching lease liability.2FASB. Leases The classification still drives the income statement. A finance lease behaves like an installment purchase, with interest and depreciation recognized separately and expense front-loaded. An operating lease produces a single, level expense across the lease term. That difference affects ratios like debt-to-equity and return on assets, which in turn affect borrowing terms.
Internal Development
When nothing off the shelf fits, you build. Proprietary software, custom production lines, and purpose-built facilities all fall here. You capitalize the direct costs of construction — materials, labor, and a reasonable share of overhead — and capitalization stops once the asset is ready for its intended use, at which point depreciation or amortization begins. Research and preliminary planning costs incurred before you commit to the project are typically expensed as incurred.
Recording the Asset on Your Books
The recorded cost, called the asset’s basis, must include every cost necessary to get the asset into working condition at its intended location. Beyond the purchase price, that means non-refundable sales taxes, freight, installation, and testing. If you demolish an existing structure to make room for a new facility, those demolition costs are added to the cost of the land rather than the new building — and because land is not depreciable, you lose the ability to write those costs off.3Office of the Law Revision Counsel. 26 U.S.C. 280B – Demolition of Structures
Not every purchase needs to be capitalized. The IRS’s de minimis safe harbor lets you expense low-cost items immediately. Businesses with an applicable financial statement (AFS) can expense items costing up to $5,000 each; without an AFS, the threshold is $2,500 per item.4Internal Revenue Service.

Writing the Cost Off Over Time
Once a tangible asset is capitalized, its cost is allocated to expense across a recovery period through depreciation. For intangibles, the equivalent is amortization. Both are reported on Form 4562.6Internal Revenue Service. About Form 4562, Depreciation and Amortization
MACRS Recovery Periods
Most U.S. businesses use the Modified Accelerated Cost Recovery System (MACRS) for tax depreciation.7Internal Revenue Service. Topic no. 704, Depreciation MACRS assigns each type of property a recovery period and front-loads deductions into the asset’s early years. Common periods include:8Internal Revenue Service. Publication 946 – How To Depreciate Property
- 5-year property: computers, vehicles, office machinery, research equipment
- 7-year property: office furniture, agricultural machinery, and property without a designated class life
- 15-year property: land improvements such as fencing, roads, and landscaping
- 27.5-year property: residential rental buildings
- 39-year property: nonresidential commercial buildings
For financial reporting, many companies use straight-line depreciation instead, spreading expense evenly across the useful life. The gap between book depreciation and tax depreciation creates a timing difference that shows up on the balance sheet as a deferred tax liability or asset.
Section 179 Expensing
The Section 179 election lets you deduct the full purchase price of qualifying business property in the year it is placed in service instead of depreciating it.9Office of the Law Revision Counsel. 26 U.S.C. 179 – Election to Expense Certain Depreciable Business Assets For 2026, the maximum deduction is $2,560,000, and it begins to phase out dollar for dollar once total qualifying property placed in service exceeds $4,090,000. The deduction disappears entirely once annual equipment purchases push past roughly $6.6 million, which makes Section 179 most useful for small and mid-sized businesses.
Bonus Depreciation
Bonus depreciation is an additional first-year deduction on qualifying property. The Tax Cuts and Jobs Act originally set the rate at 100% for property placed in service after September 27, 2017, then phased it down by 20 percentage points a year starting in 2023. Subsequent legislation restored the full 100% first-year deduction, so the entire cost of qualifying assets can be written off in the year they are placed in service.10Internal Revenue Service. Additional First Year Depreciation Deduction (Bonus) – FAQ Unlike Section 179, bonus depreciation has no dollar cap and no phase-out based on total spending, which makes it especially useful for large acquisitions.
Amortizing Acquired Intangibles
Acquired intangibles follow a separate rule. Under Section 197, most intangibles obtained as part of a business acquisition are amortized on a straight-line basis over 15 years regardless of actual expected useful life.11Office of the Law Revision Counsel. 26 U.S.C. 197 – Amortization of Goodwill and Certain Other Intangibles The list is broad: goodwill, going concern value, customer lists, patents, copyrights, trademarks, trade names, covenants not to compete, government licenses, and workforce-in-place arrangements. The uniform 15-year period sidesteps the problem of estimating useful life for assets like brand recognition or customer relationships.
Capital Expenditure or Operating Expense?
Capital expenditures add value to an asset, extend its useful life, or adapt it to a new purpose. They are capitalized and depreciated. Operating expenses are routine costs that keep an existing asset running in its current condition and hit the income statement immediately.
The line is not always obvious. Replacing a machine’s entire motor is a capital expenditure because it extends the machine’s useful life. Changing the oil and filters is an operating expense because it merely maintains the existing condition. The gray zone is where trouble starts. Replacing the roof on a rental property may be a repair or an improvement depending on whether the work addresses a single component or substantially improves the entire building. Capitalizing routine maintenance inflates your asset values; expensing a genuine improvement gives you a larger immediate deduction but understates the balance sheet and can draw scrutiny on audit.
When You Sell: Depreciation Recapture
Capital acquisition accounting does not end when you stop using the asset. On sale, you compare proceeds against book value (original cost less accumulated depreciation). Proceeds above book value produce a gain; below, a loss.
The tax side adds a wrinkle that catches many owners off guard. Every dollar of depreciation you claimed reduced ordinary income at ordinary rates. When you sell the asset for more than its depreciated book value, Section 1245 requires you to recapture that depreciation as ordinary income, up to the amount of gain on the sale.12Office of the Law Revision Counsel. 26 U.S.C. 1245 – Gain From Dispositions of Certain Depreciable Property Recapture applies not just to regular depreciation but also to Section 179 deductions and bonus depreciation.13Internal Revenue Service. Publication 544 – Sales and Other Dispositions of Assets Only gain exceeding total depreciation previously claimed is taxed as capital gain. Aggressive first-year expensing therefore builds a larger potential recapture liability if you later sell the asset for a meaningful price.
When the Asset Loses Value Faster Than Expected
Depreciation assumes an orderly, predictable decline. If an asset loses value faster than the schedule anticipated — market conditions shift, a regulation changes, cash flows disappoint — GAAP requires an impairment test under ASC 360-10. The test is not annual. You test when a triggering event occurs, such as a significant drop in market price, a major adverse change in use, cost overruns, or a pattern of operating losses tied to the asset. If the asset’s undiscounted future cash flows fall short of its carrying value, you write it down to fair value and record the loss on the income statement. Impairment losses on long-lived assets are permanent under GAAP; you cannot reverse them if value later recovers.
Evaluating an Acquisition Before You Commit
The accounting follows the decision, so the real work happens before you sign. Net present value (NPV) discounts the asset’s expected future cash flows back to the present using your cost of capital. A positive NPV means the asset creates more value than it costs. Internal rate of return (IRR) tells you the effective annual return the asset is expected to generate; compare it to your weighted average cost of capital, which blends the after-tax cost of debt with the return equity investors demand. If projected IRR does not exceed WACC, the acquisition earns less than it costs to finance. Payback period is a useful gut-check on liquidity risk but ignores the time value of money.
The choice among Section 179, bonus depreciation, and standard MACRS is a cash flow decision as much as a tax one. Expensing the full cost in year one creates a large immediate tax shield, valuable when cash is tight, but leaves no depreciation deductions in later years. If income is expected to grow, spreading the deduction through MACRS may produce a better overall result. Run the numbers both ways before you file.
