Can You Choose Not to Depreciate an Asset? The Allowable Rule

You can decline to claim depreciation on a business or investment asset, but doing so is almost always a mistake. Under federal law, the IRS reduces your asset’s cost basis by the full depreciation you were entitled to claim, whether or not you actually took the deduction. Choosing not to depreciate an asset leaves the current-year deduction on the table and still leaves you with the same taxable gain when you sell.¹

Depreciation Is Not Really Optional

Section 167 of the Internal Revenue Code allows a “reasonable allowance” for wear and tear on property used in a trade or business or held to produce income.² The word “allowed” sounds like a permission slip, but once qualifying property is placed in service, the IRS treats depreciation as a required accounting method rather than a year-by-year choice. Section 168 then assigns each type of asset a specific method, recovery period, and convention under the Modified Accelerated Cost Recovery System.³

You do not get to invent your own schedule, and you do not get to opt out. What you do get is some real flexibility over speed, which is covered further down.

The “Allowed or Allowable” Rule Is Where People Get Hurt

Section 1016 requires that an asset’s basis be reduced by depreciation “allowed or allowable.” The statute is explicit that the reduction cannot be less than the amount allowable, even if a smaller amount, or nothing at all, was actually claimed.¹ In plain English: the IRS figures out what you could have deducted and shrinks your basis by that full amount regardless.

Say you buy equipment for $50,000 and over several years $20,000 of MACRS depreciation becomes allowable. If you only claimed $10,000 during those years, your adjusted basis when you sell is still $30,000, not $40,000. You forfeited $10,000 in deductions and got no credit for that sacrifice when computing your gain.⁴ The unclaimed depreciation simply vanishes.

That is why the “just don’t depreciate” idea is one of the worst moves a taxpayer can make. You pay more tax now and still face the same gain later.

You Still Owe Recapture on Depreciation You Skipped

The financial consequences arrive when you sell. Because the allowed-or-allowable rule has already lowered the basis by every dollar of depreciation you were entitled to, the gain is larger than it would be on a non-depreciable asset. Skipping the annual deduction does not shrink this gain.

For tangible personal property such as equipment, machinery, and vehicles, Section 1245 recaptures the full amount of depreciation as ordinary income rather than at capital gains rates.⁵ For depreciable real estate, the straight-line depreciation previously allowable is taxed as unrecaptured Section 1250 gain at a maximum federal rate of 25 percent.⁶

A rental property owner who never claimed a single year of depreciation still faces the 25 percent recapture on the depreciation that was allowable. The code does not reward the omission.

Fixing Depreciation You Already Missed

If you have already gone years without claiming depreciation you were entitled to, the fix is IRS Form 3115, Application for Change in Accounting Method. The IRS treats a failure to depreciate, or the use of an incorrect method, as an impermissible accounting method that must be corrected through a formal method change rather than by amending each prior return.⁷

When you file Form 3115 to switch from not depreciating to a permissible method, the IRS computes a Section 481(a) adjustment representing all the depreciation you should have claimed in prior years. Because this adjustment reduces your taxable income, the entire catch-up amount is deducted in the single year you file the form rather than being spread over multiple years. For someone who skipped depreciation on a rental property for a decade, that one-time adjustment can be substantial.

Timing matters. If only one year has passed since the error, you can typically correct it by amending that return. Once two or more years of returns have used the incorrect method, Form 3115 becomes the required path. For assets still in service, the change is filed under Designated Change Number (DCN) 7; for assets already sold, DCN 107 applies.⁷ In most cases this qualifies as an automatic consent change, so you attach the completed form to a timely filed return for the year of change rather than requesting individual IRS approval.

The Form 3115 route is favorable. Instead of losing unclaimed deductions permanently, you recover them all at once. If you suspect you have been under-depreciating or failing to depreciate qualifying assets, this is one area where engaging a tax professional pays for itself quickly.

Property You Genuinely Cannot Depreciate

“Choosing not to depreciate” is different from property that simply does not qualify. The most important exclusion is land. Because land does not wear out, become obsolete, or get used up, you cannot depreciate it.⁴ When you buy real estate, you must allocate the purchase price between the building, which is depreciable, and the land beneath it, which is not. Assigning too much value to the building is a common audit trigger.

Other property you cannot depreciate includes assets held purely for personal use, inventory held for sale to customers, and property placed in service and disposed of in the same year. Equipment sitting in a warehouse that has never been placed in service does not start its depreciation clock until it is actually put to use.

Ways to Legitimately Control the Speed

You cannot opt out of depreciation, but you have real flexibility over how quickly you take it. The practical choice is between writing off the cost immediately or spreading it across the MACRS recovery period.

Section 179 Expensing

Section 179 lets you elect to deduct the entire cost of qualifying property in the year it is placed in service. For 2026, the maximum amount that can be expensed is approximately $2,560,000 (inflation-adjusted from a $2,500,000 statutory base), phasing out dollar for dollar once total qualifying property placed in service exceeds roughly $4,090,000.⁸ The Section 179 deduction cannot create or increase a net loss; any unused amount carries forward.

Bonus Depreciation

Bonus depreciation under Section 168(k) allows an immediate first-year deduction of a percentage of an asset’s cost. The One Big Beautiful Bill Act permanently restored the bonus rate to 100 percent for qualified property acquired and placed in service after January 19, 2025.⁹ Unlike Section 179, bonus depreciation has no annual dollar cap and can generate or increase a net operating loss.

If you want to slow deductions down rather than accelerate them, you can elect out of bonus depreciation by class of property on a timely filed return, including extensions. If you missed the deadline, you can still elect out by filing an amended return within six months of the original due date, excluding extensions.¹⁰ Once made, the election is irrevocable without IRS consent.

Alternative Depreciation System

For taxpayers who want to stretch deductions over longer periods, the Alternative Depreciation System under Section 168(g) uses straight-line with longer recovery periods than standard MACRS. Some property is required to use ADS, such as assets used predominantly outside the United States or property financed with tax-exempt bonds. Others elect into it voluntarily to defer deductions to future higher-income years.

De Minimis Safe Harbor

For lower-cost items, the de minimis safe harbor election lets you deduct the full cost of tangible property without capitalizing and depreciating it at all. The threshold is $5,000 per invoice or item if you have audited financial statements, or $2,500 per invoice or item if you do not.¹¹ The election is made annually on your tax return and applies to each qualifying purchase individually. For a business that routinely buys laptops, tools, or small equipment, it can eliminate the need to track depreciation on dozens of low-value items.
