How Should You Record a Capital Expenditure?

To record a capital expenditure, debit the appropriate fixed asset account (Equipment, Building, Machinery, or similar) for the full cost basis and credit cash or accounts payable for the same amount. That single entry puts the purchase on your balance sheet instead of running it through the income statement. From there, periodic depreciation entries shift the cost into expense across the years the asset is in service. Getting these entries right matters for tax compliance and clean financial statements, and it protects you from accuracy-related penalties that reach 20% of any resulting tax underpayment.¹

Figure Out the Cost Basis First

The number you debit is not the sticker price. Cost basis includes everything needed to get the asset ready for use: sales tax, freight, installation, testing, excise taxes, and any legal or recording fees tied to the purchase.² A $40,000 machine that costs $2,200 to ship and $3,500 to install goes on the books at $45,700. Miss one of those components and your depreciation deductions will be wrong for the entire life of the asset.

Pull the numbers from purchase orders, shipping invoices, and contractor receipts at the time of acquisition. You also need the date the asset was placed in service, which the IRS defines as the date it was ready and available for its intended use, even if you had not started using it yet.³ That date sets when depreciation begins and which tax year claims the first deduction. Manufacturer specifications help you estimate useful life and salvage value, both of which feed the depreciation math.

One boundary before you record anything: not every long-lived purchase has to be capitalized. Under the de minimis safe harbor, a business with an applicable financial statement can expense items costing up to $5,000 per invoice; without one, the cap is $2,500 per invoice. You elect this treatment on your tax return each year.⁴ Items under your chosen threshold go straight to an expense account and skip the capitalization process entirely.

The Initial Journal Entry

Once you have the cost basis, the entry itself is short:

Debit Equipment (or Machinery, Building, Vehicles) for the full cost basis, including freight, tax, and installation.
Credit Cash if you paid outright, or Accounts Payable if the vendor invoiced you on terms, for the same total.

The debit raises total assets on the balance sheet. The credit either lowers cash or raises a liability by the matching amount. Most accounting software will prompt you for a description, vendor name, and asset tag number. Fill all of them. Two years later, when an auditor asks about a line item, searchable descriptions save hours of digging.

Before the entry hits the ledger, route the purchase through an internal approval workflow. A capital expenditure request typically includes the cost breakdown, a justification, the proposed funding source, and the name of the person responsible for the asset. The dollar threshold that triggers approval varies by company, but the principle is constant: someone other than the requester signs off before money moves. Skipping this is one of the fastest ways to create the kind of internal control gap auditors flag.

Depreciation Entries Over Time

The asset is on the books, but it is wearing out, and your entries need to reflect that. Depreciation spreads the cost basis (minus estimated salvage value) across the years you use the asset. The IRS describes depreciation as an annual income tax deduction that lets you recover the cost of property over the time you use it.³

Each period, record:

Debit Depreciation Expense. This hits the income statement and reduces reported profit.
Credit Accumulated Depreciation. This is a contra-asset account that lowers the asset’s carrying value on the balance sheet without erasing the original cost.

The simplest method is straight-line: divide the depreciable amount evenly across each year. A $50,000 asset with a $5,000 salvage value and a 5-year life produces $9,000 in depreciation expense per year. For intangibles like patents or software licenses, amortization works the same way. Most businesses record these entries monthly or at fiscal year-end.

MACRS Recovery Periods for Tax

For your federal tax return, the IRS assigns assets to specific recovery classes under the Modified Accelerated Cost Recovery System:

5-year property: computers, vehicles, and appliances used in rental properties.
7-year property: office furniture, fixtures, and safes.
27.5-year property: residential rental buildings.
39-year property: nonresidential commercial buildings.

Tax recovery periods do not have to match the useful life you use for financial statements.³ A piece of equipment might depreciate over 10 years in your books but 7 years on your tax return. That mismatch is normal and produces a temporary timing difference between book income and taxable income.

When First-Year Deductions Change the Entry

Two provisions let you front-load a large piece of the deduction into the year you place the asset in service, and both change how the initial entry looks.

Section 179 Expensing

Section 179 allows you to elect to deduct the full cost of qualifying property in the year you buy it, rather than capitalizing and depreciating over time.⁵ For tax years beginning in 2026, you can expense up to $2,560,000 of qualifying property. The deduction phases out dollar-for-dollar once total qualifying property placed in service during the year exceeds $4,090,000. Sport utility vehicles carry a separate $32,000 cap.⁶

When you elect Section 179, the debit side of the entry changes. Instead of debiting a fixed asset account, you debit an expense account for the elected amount. If you expense the entire cost, nothing goes on the balance sheet as a long-term asset. If you expense only part, the remainder is capitalized and depreciated normally. The election is made on IRS Form 4562 with your return.

Bonus Depreciation

Bonus depreciation under Section 168(k) provides an additional first-year deduction on top of regular depreciation. Under the One, Big, Beautiful Bill signed into law in 2025, businesses can deduct 100% of the cost of qualifying property placed in service after January 19, 2025.⁷ Qualifying property generally includes assets with a MACRS recovery period of 20 years or less, certain computer software, and water utility property.⁸

Unlike Section 179, bonus depreciation has no dollar ceiling and no phase-out. It applies automatically unless you elect out. For a business placing large amounts of equipment in service, combining Section 179 with bonus depreciation can eliminate the tax cost of a capital purchase in the year it happens.

Recording the Disposal

When you sell, scrap, or retire the asset, one final entry closes it out. The entry removes both the original cost and all accumulated depreciation, records any cash received, and recognizes a gain or loss.

Debit Accumulated Depreciation for the full amount recorded over the asset’s life.
Debit Cash for whatever the buyer paid, if sold.
Credit the Fixed Asset account for the original cost basis.
Debit or credit Gain or Loss on Disposal for the difference between proceeds and book value (cost minus accumulated depreciation).

If the sale price exceeds book value, you have a gain. If book value exceeds the sale price, you have a loss. When an asset is scrapped with no proceeds, the entire remaining book value becomes a loss. This is where sloppy depreciation records come back to bite. If accumulated depreciation is wrong because entries were missed or the wrong recovery period was applied, the disposal gain or loss will be wrong, and that error flows straight into taxable income.

Records and Penalties

Keep records for a capitalized asset until the statute of limitations expires for the tax year in which you dispose of it. Because depreciation deductions span many years and disposal triggers a final gain or loss, that effectively means holding purchase invoices, installation receipts, and depreciation schedules for the entire ownership period plus at least three years after sale or retirement. Underreport income by more than 25% and the window stretches to six years. Fraudulent returns have no time limit.⁹

Misclassifying a capital expenditure as a current expense inflates your deductions and understates your tax liability. The IRS treats this as either negligence or a substantial understatement of income tax, both of which trigger the accuracy-related penalty of 20% of the underpayment.¹ Interest runs on the penalty from the original due date of the return. For a business that improperly expensed a $200,000 piece of equipment, the resulting underpayment can easily produce a five-figure penalty before interest.

The fix is tedious but not complicated. Maintain a fixed asset register, reconcile it to the general ledger at least quarterly, and apply your capitalization threshold consistently rather than deciding item by item. And keep in mind the line between capital and expense on work done to existing assets: under the IRS improvement rules, work that betters an asset, adapts it to a new use, or restores it after a major breakdown gets capitalized, while routine upkeep is expensed.⁴ Replacing a truck engine gets capitalized. Changing the oil does not.
