Investor Captures $340K via Form 3115 Catch-Up Depreciation on 3 Properties

The Problem

This client owned three long-term rental properties purchased between 5 and 9 years earlier with a combined original purchase price of $1.85M. All three properties had been depreciated on standard 27.5-year straight-line schedules by the prior CPA, with a combined annual depreciation deduction of approximately $57,400. Over the years of ownership, the client had claimed a total of approximately $385,000 in straight-line depreciation across the portfolio. No cost segregation study had ever been performed on any of the properties.

The client had recently qualified for Real Estate Professional Status after leaving a W-2 position to manage the rental portfolio full-time. With REPS now established, the client could use rental losses to offset the spouse's $420,000 W-2 income. However, the straight-line depreciation of $57,400 per year created only modest losses against the $186,000 in gross rental income. The client needed significantly more depreciation to generate meaningful losses. Cost segregation studies on all three properties, combined with Form 3115 catch-up depreciation, would capture years of missed accelerated deductions in a single year.

AE Tax Strategy

1. Cost Segregation Studies on Three Existing Properties Under IRC §168

We commissioned cost segregation studies on all three properties. Property 1 ($780,000, owned 9 years): $273,000 in reclassifiable components. Property 2 ($620,000, owned 7 years): $211,000 in reclassifiable components. Property 3 ($450,000, owned 5 years): $153,000 in reclassifiable components. Combined reclassifiable basis: $637,000. The studies identified the components that should have been placed in 5-year, 7-year, and 15-year recovery periods from the date of original acquisition.

2. Form 3115 Catch-Up Depreciation Under IRC §481(a)

We filed three Form 3115 applications (one per property) to change the depreciation method from straight-line 27.5-year to the correct accelerated method for each component. The Section 481(a) adjustment for each property calculated the difference between depreciation actually claimed and depreciation that would have been claimed had cost segregation been done at acquisition. Property 1: $148,000 catch-up. Property 2: $112,000 catch-up. Property 3: $80,000 catch-up. Total Section 481(a) favorable adjustment: $340,000, deductible in full in the year of change as a one-time lump-sum deduction.

3. REPS Qualification and Loss Utilization

With the client qualifying for Real Estate Professional Status (2,100 hours in real property trades or businesses, zero hours in other trades or businesses) and material participation in all three properties (documented through 680 hours of direct management), the $340,000 catch-up depreciation created a substantial non-passive loss. Against the spouse's $420,000 W-2 income, the loss offset a significant portion, producing approximately $119,000 in tax savings at the combined 35% federal marginal rate (no state income tax in Texas).

Before & After Comparison

Property 2 Catch-Up (7 Years)	$0	$112,000	$112,000
Property 3 Catch-Up (5 Years)	$0	$80,000	$80,000
Tax Savings at 35%	$0	$119,000	$119,000
Total	$0	$340,000	$340,000 (catch-up deduction)

Key Takeaways

• Form 3115 catch-up depreciation does not require amending prior returns — the entire adjustment is taken in the current year as a Section 481(a) adjustment.
• Properties owned for many years often produce larger catch-up adjustments because more years of missed accelerated depreciation have accumulated.
• The automatic change procedures under Rev. Proc. 2015-13 do not require IRS approval — the Form 3115 is attached to the return and a copy is filed with the IRS national office.
• REPS qualification is often the key that unlocks the full value of Form 3115 catch-up depreciation for real estate investors with high W-2 or business income.
