What If I Never Took Depreciation on My Rental? (2026)

This is the worst position in rental real estate, and it is more common than you would expect. An owner who never claimed depreciation still owes recapture tax at sale, because the code measures recapture by depreciation allowed or allowable.

You pay tax on a deduction you never received. The good news is that the fix does not require amending anything and can produce a very large deduction in the current year.

Allowed or Allowable Is the Governing Phrase

IRC Sec. 1016(a)(2) reduces basis by depreciation allowed, or allowable if greater. IRC Sec. 1250 then measures recapture against that reduced basis.

The practical result is that basis goes down whether or not you claimed the deduction. An owner who held a rental for twelve years and never depreciated it has the same adjusted basis as an owner who depreciated it correctly, and faces the same unrecaptured Sec. 1250 gain at up to 25% on sale.

There is no election to skip depreciation. It is not optional, and declining to claim it produces no benefit of any kind.

Why Amending Does Not Fix It

Amended returns are limited by the statute of limitations under IRC Sec. 6511, generally three years from filing or two years from payment.

An owner who missed depreciation for twelve years can amend at most the last three. The other nine years are closed and the deductions are permanently lost through that route.

There is also a technical problem. Failing to claim depreciation for two or more consecutive years establishes an impermissible method of accounting. Once a method is established, it is corrected through a method change under IRC Sec. 446(e), not through amended returns. The IRS position on this is longstanding and consistent.

Form 3115 Recovers Everything

A change from an impermissible depreciation method to a permissible one is an automatic change in method of accounting. It is filed on Form 3115 with the current year return, and the cumulative effect is claimed as a Sec. 481(a) adjustment.

A negative Sec. 481(a) adjustment, meaning one that decreases income, is taken entirely in the year of change. All twelve years of missed depreciation land in one current-year deduction.

No amended returns are required. No prior years are reopened. The automatic change procedures under the applicable revenue procedure govern, and the change is made without a user fee.

There is a duplicate copy requirement, filing one copy with the return and one with the IRS national office, and the copy must be filed by the return's filing date including extensions.

What This Is Worth

An owner with a $410,000 rental placed in service in 2013 with $340,000 allocated to the building has been entitled to $12,364 of annual depreciation. Over thirteen years that is $160,732.

Filing Form 3115 in the current year produces a $160,732 deduction. At a 32% marginal rate that is $51,434 of tax reduction in one year.

If the owner also runs a cost segregation study as part of the same method change, the catch-up includes both the missed straight-line depreciation and the accelerated portion the study identifies. That combination frequently doubles the adjustment.

The deduction is subject to the passive activity rules under IRC Sec. 469. An owner without real estate professional status or passive income will suspend the loss, which is still better than losing it, but the timing should be planned.

The Partial Depreciation Case

A related and equally common situation is depreciating the building but not the land improvements, or using the wrong recovery period, or never adjusting after a major renovation was capitalized incorrectly.

All of these are method issues correctable through the same mechanism. A property depreciated over 39 years that should have been on 27.5 years, or a residential rental where $60,000 of site work was folded into the building rather than depreciated over 15 years, both produce a favorable Sec. 481(a) adjustment.

Where the error is in the opposite direction, meaning too much depreciation was claimed, the adjustment is positive and increases income. That is spread over four years under the automatic change procedures, which softens it considerably.

Do This Before You Sell

The catch-up is only useful while you still own the property. Once the property is sold, the method change is unavailable and the recapture applies to depreciation you never claimed.

Owners considering a sale should run the correction first, take the catch-up deduction against current income, and then sell. The recapture on sale is unchanged, since it was going to apply either way, but at least the deduction was received.

For an owner planning a 1031 exchange, the timing is similar. Correct the method, claim the adjustment, then exchange.

Worked Example: Thirteen Years of Missed Depreciation

An investor bought a duplex in 2013 for $395,000 with $75,000 allocated to land. They reported rental income and expenses each year but never claimed depreciation, because their preparer never asked and they did not know to.

Correct annual depreciation on the $320,000 building is $11,636. Over thirteen years, $151,268 was allowable but never claimed.

A cost segregation study on the property identifies $76,800 of five-year and 15-year property that should have been separately depreciated, adding further catch-up.

Form 3115 is filed with the current year return. The combined Sec. 481(a) adjustment is approximately $209,000, deductible in full in the current year.

The investor qualifies for real estate professional status through their spouse and has made the aggregation election, so the loss is non-passive. At a combined 38% marginal rate, the correction produces roughly $79,400 of tax reduction.

Without the correction, the same investor would have paid unrecaptured Sec. 1250 gain at up to 25% on $151,268 at sale, roughly $37,800, on deductions never received.

Frequently Asked Questions

Do I owe recapture on depreciation I never claimed?

Yes. IRC Sec. 1016(a)(2) reduces basis by depreciation allowed or allowable, whichever is greater. Skipping depreciation gives you no benefit and no protection. You owe the same recapture as an owner who claimed it correctly.

Can I just amend my old returns?

Only three years back under IRC Sec. 6511, and even that is technically the wrong mechanism. Failing to claim depreciation for two or more consecutive years establishes an impermissible accounting method, which is corrected by a method change under IRC Sec. 446(e), not by amending.

How does Form 3115 recover the missed depreciation?

It is an automatic change from an impermissible to a permissible method. The cumulative missed depreciation is claimed as a Sec. 481(a) adjustment entirely in the year of change. No prior returns are amended and no years are reopened.

Is there a limit on how many years I can recover?

No. The Sec. 481(a) adjustment captures the entire cumulative difference regardless of how many years are involved. An owner who missed twenty years of depreciation recovers all twenty in the current year.

Can I still do this if I am selling the property?

Only before the sale closes. Once the property is disposed of, the method change is unavailable and you will pay recapture on depreciation you never received. Run the correction first, claim the adjustment, then sell or exchange.
