Whether to depreciate or expense assets comes down to three things: whether your business has enough income this year to use a big deduction, what tax bracket you expect to be in later, and how soon you plan to sell the property. For 2026, the restored 100-percent bonus depreciation lets most businesses write off the full cost of qualifying equipment in the year they place it in service, so immediate expensing is the default answer for profitable companies. Startups, businesses expecting higher future income, and owners who plan to sell equipment within a few years often come out ahead by spreading the deduction instead.
What “Expensing Now” Actually Means in 2026
Three separate provisions let you deduct the cost of business property in the year you buy it. They work differently and stack in a specific order, so knowing which one applies to a given purchase matters more than picking a favorite.
Section 179 lets you elect to treat qualifying property as an immediate expense. For tax years beginning in 2026, the maximum deduction is $2,560,000, phasing out dollar-for-dollar once you place more than $4,090,000 of qualifying property in service and disappearing entirely at $6,650,000.1Office of the Law Revision Counsel. 26 USC 179 – Election To Expense Certain Depreciable Business Assets Qualifying property generally includes machinery, computers, off-the-shelf software, office equipment, and certain improvements to nonresidential buildings. The asset must be used more than 50 percent for business, and only the business-use portion counts.
The important constraint: your Section 179 deduction cannot exceed your total taxable income from all active trades or businesses for the year.2eCFR. 26 CFR 1.179-2 – Limitations on Amount Subject to Section 179 Election If you buy $200,000 of equipment but your combined business income is $120,000, your deduction is capped at $120,000 this year. The disallowed portion carries forward to future years.3eCFR. 26 CFR 1.179-3 – Carryover of Disallowed Deduction
Bonus depreciation under Section 168(k) is the second path. The One, Big, Beautiful Bill restored 100-percent bonus depreciation for most qualifying property acquired after January 19, 2025, so businesses can deduct the full cost of eligible assets placed in service during 2026 in a single year.4Internal Revenue Service. One, Big, Beautiful Bill Provisions Qualifying property includes tangible assets with a recovery period of 20 years or less, certain computer software, and water utility property. Both new and used property can qualify, as long as the asset was not previously used by the same taxpayer.5Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System
Bonus depreciation has no dollar cap and no taxable income limitation. It can even create or increase a net operating loss, which carries forward to offset future income. That is the practical dividing line between the two: Section 179 stops at your current business income; bonus depreciation does not.
The de minimis safe harbor handles low-cost purchases without the paperwork. If your business does not have audited financial statements, you can deduct items costing $2,500 or less per invoice or per item. Businesses with applicable financial statements can use a $5,000 threshold.6Internal Revenue Service. Tangible Property Regulations – Frequently Asked Questions The election is made each year with a statement on your timely filed return and eliminates the need to track multi-year depreciation for routine items like keyboards and small tools.
When Expensing Is the Better Call
Expensing works best when your business is currently profitable and taxed at a relatively high rate. Taking the full deduction now cuts your current tax bill and frees cash for operations, hiring, or more investment. If you expect income to hold steady or drop, locking in the deduction while your rate is highest produces the biggest tax savings.
Bonus depreciation is the right vehicle for large purchases that outrun your current-year business income. Because it has no income cap, it can generate or enlarge a net operating loss that offsets future income. Section 179 alone cannot do that. For most small and mid-size businesses buying standard equipment in 2026, the practical approach is to apply Section 179 first up to the income limit, then let bonus depreciation absorb the rest.
When Spreading Deductions Over Time Wins
A startup or early-stage business with little taxable income often gets more value from MACRS depreciation spread over several years.7Internal Revenue Service. Publication 946 – How To Depreciate Property If you expect revenue and your bracket to rise, future deductions will offset income taxed at a higher rate. A $50,000 deduction is worth more against income taxed at 32 percent than against income taxed at 12 percent.
MACRS assigns each type of property a fixed recovery period: five years for automobiles, computers, and office machinery; seven years for office furniture and fixtures; 15 years for qualified improvement property; 27.5 years for residential rental buildings; and 39 years for nonresidential real property. For 5-year and 7-year property, the 200-percent declining balance method front-loads deductions in the early years.
Businesses in cyclical industries sometimes prefer gradual depreciation to smooth their tax liability year to year, rather than creating a single large deduction that produces minimal savings in a lean year followed by a spike in liability the next.
The Catch on Resale: Depreciation Recapture
Any gain attributable to prior depreciation deductions, including Section 179, is taxed as ordinary income rather than at the lower capital gains rate when you sell the asset. This is depreciation recapture under Section 1245.8Office of the Law Revision Counsel. 26 USC 1245 – Gain From Dispositions of Certain Depreciable Property
A simplified example: you buy equipment for $80,000 and expense the full amount under Section 179 in year one, reducing your basis to zero. Three years later you sell it for $30,000. That entire $30,000 is ordinary income because it falls within the depreciation you previously claimed.
If you sell for more than the original cost, only the portion of gain equal to the depreciation claimed is recaptured as ordinary income. Gain above the original cost is treated as a Section 1231 gain, which generally qualifies for long-term capital gains rates if the property was held more than one year.9Office of the Law Revision Counsel. 26 USC 1231 – Property Used in the Trade or Business and Involuntary Conversions You report the sale on Form 4797.10Internal Revenue Service. 2025 Instructions for Form 4797 – Sales of Business Property
Recapture does not erase the benefit of expensing. You still got the time value of the upfront deduction. But if you plan to resell equipment after a few years, the recapture tax reduces the real advantage of expensing over stretching the deduction across a longer schedule. Factor it in before choosing.
Vehicles and Listed Property: Special Limits
Passenger automobiles face annual depreciation caps under Section 280F that override Section 179 and bonus depreciation. For vehicles placed in service in 2025 — the most recently published limits — the first-year cap is $20,200 if bonus depreciation applies and $12,200 if it does not. Years two through four are capped at $19,600, $11,800, and $7,060, then $7,060 for each year after until the vehicle is fully depreciated.11Internal Revenue Service. Rev. Proc. 2025-16 The IRS updates these amounts annually, so confirm the current figure for 2026.
Heavy vehicles with a gross vehicle weight rating above 6,000 pounds but no more than 14,000 pounds are not subject to the passenger auto caps. Certain heavy SUVs designed primarily to carry passengers can take a Section 179 deduction inflation-adjusted to roughly $32,000 for 2026, and the remaining basis may qualify for 100-percent bonus depreciation. Trucks and vans not designed primarily for passengers, such as cargo vans, face no special vehicle cap beyond the general Section 179 limits.
Listed property — vehicles, computers used at home, and similar items the IRS considers prone to personal use — must be used more than 50 percent for business to qualify for Section 179 or accelerated MACRS. If business use drops to 50 percent or below in a later year, you must recompute depreciation under the straight-line method as if you had used it from the start, and any Section 179 deduction is treated as if it never happened for that recalculation.12eCFR. 26 CFR 1.280F-3T – Limitations on Recovery Deductions and the Investment Tax Credit When Business Use Percentage Is Not Greater Than 50 Percent The difference between what you deducted and what straight-line would have allowed comes back as ordinary income in the year business use falls. Keep mileage or usage logs the entire time recapture could apply, even after the asset is fully depreciated.
How to Claim the Deduction You Pick
Report depreciation and expensing elections on Form 4562, attached to your business return. Part I handles Section 179; Part III covers MACRS, where you list each asset’s depreciable basis, recovery period, and applicable convention.13Internal Revenue Service. Instructions for Form 4562
Keep a depreciation log for every asset with the purchase date, original cost, recovery period, and business-use percentage, backed by receipts. The IRS requires you to keep property records until the statute of limitations expires for the year you dispose of the asset, not the year you bought it. For most taxpayers, that means holding records at least three years after selling or scrapping the equipment.14Internal Revenue Service. How Long Should I Keep Records
If you pick the wrong method or recovery period and have already filed, correcting it means filing Form 3115 to request a change in accounting method.15Internal Revenue Service. About Form 3115 – Application for Change in Accounting Method The process is detailed and slow. Misclassifying a 5-year asset as 7-year property delays your deductions and can trigger interest on underpaid tax if the error surfaces in an audit. Getting the choice right on the original return is worth the time it takes to think through.
