What Form 3115 Catch-Up Depreciation Is
One of the more powerful but least-known tax strategies available to real estate investors and business owners is the Form 3115 catch-up depreciation procedure. The strategy allows recovery of missed depreciation from prior years, sometimes spanning a decade or more, without amending any prior returns. The entire catch-up adjustment is taken as a current year deduction.
For investors with property portfolios that have been depreciated under standard methods rather than cost segregation, Form 3115 represents one of the higher-impact tax conversations available. AE Tax Advisors has developed specialized expertise in the Form 3115 process and integrates it into the firm’s planning framework for real estate investors.
How the Catch-Up Depreciation Adjustment Works
Form 3115 is the Application for Change in Accounting Method. The form is filed with the IRS to request a change from one accounting method to another, including a change in depreciation method or recovery period for property in service. The most common application in real estate is the change from standard 27.5-year or 39-year depreciation to the accelerated MACRS classes (5-year, 7-year, 15-year) identified through a cost segregation study performed in a later year.
The value of Form 3115 is that the IRS allows the entire catch-up depreciation to be claimed as a §481(a) adjustment in the year the form is filed. A real estate investor who purchased a property in 2018 and never ran a cost segregation study can run the study in 2026 and claim all catch-up depreciation that should have been taken from 2018 through 2026 in a single current-year deduction.
The catch-up can be substantial. Consider a real estate investor with $3 million of rental property purchased six years ago, depreciated under standard methods. A retroactive cost segregation study identifies 30% of the basis as 5-year, 7-year, and 15-year property. The catch-up depreciation, which is the difference between what was claimed under the standard method and what should have been claimed under the accelerated method, accumulated across six years, is captured in a single current-year deduction rather than through multiple amended returns.
How Form 3115 Compares to Amending Prior Returns
The procedure has several specific advantages over amending prior returns.
The first advantage is simplicity. Filing Form 3115 requires a single current-year filing rather than multiple amended returns for prior years. The procedure also does not require IRS approval before the change is made, because many depreciation changes are designated as “automatic” changes under Revenue Procedure 2015-13 and subsequent guidance.
The second advantage is the absence of audit triggers. Amended returns often draw additional IRS scrutiny because they invite examination of the years being amended. Form 3115 changes the accounting method going forward and applies the catch-up adjustment to the current year, which is structurally different from amending a prior year.
The third advantage is the statute-of-limitations interaction. Amended returns are limited by the three-year statute from the original filing date, which means depreciation missed in years more than three years ago typically cannot be recovered via amendment. Form 3115 has no such limitation because the §481(a) adjustment is applied to the current year regardless of when the underlying depreciation should have been claimed.
The fourth advantage is the §481(a) treatment itself. The catch-up is treated as a current-year deduction, which means it can interact with the taxpayer’s current-year tax situation by offsetting current income, creating current-year losses, and potentially activating other strategies, such as Real Estate Professional Status, that require current-year activity to deploy.
How AE Tax Advisors Handles the Form 3115 Process
AE Tax Advisors executes the Form 3115 process as part of the broader advisory engagement. The firm’s team of IRS Enrolled Agents and licensed CPAs coordinates the cost segregation study, prepares the Form 3115 filing, calculates the §481(a) adjustment, and integrates the catch-up depreciation into the client’s overall tax strategy. The annual $7,800 advisory engagement includes the planning and execution work. The cost segregation study itself is priced separately based on property complexity.
The proprietary 3-Year Tax Lookback that AE Tax Advisors runs at the start of every engagement specifically evaluates whether Form 3115 catch-up opportunities exist for the client’s existing property portfolio. The lookback identifies properties where cost segregation should have been performed but was not, and quantifies the catch-up depreciation available through the Form 3115 procedure.
For real estate investors whose property portfolios have been depreciated under standard methods, the Form 3115 conversation with AE Tax Advisors can be one of the more consequential planning moves available under the tax code. The recovery is grounded in established procedures, and the firm’s technical depth in this area is one reason real estate investors nationwide have engaged AE Tax Advisors for this strategy.
