This case study examines how a physician with $1.2M in W-2 income owned multiple long-term rental properties that had been held for 8+ years with incorrect depreciation calculations. Through Form 3115 (accounting method change) and coordinated depreciation correction, the physician recovered approximately $94,000 in missed deductions while simultaneously optimizing future depreciation strategy.
The Client Situation
Our client was a surgical specialist earning $1.2M annually in W-2 compensation. The client owned five long-term rental properties (all single-family homes) acquired over 8 years, with combined basis of approximately $1.8M.
The client had been filing Schedule E with depreciation deductions each year, but the depreciation calculations had not been updated to properly account for capital improvements, basis adjustments, or proper land-to-building allocation. The client's own tax preparer had been using a simplified "rule-of-thumb" depreciation percentage rather than actual MACRS calculations.
Our analysis identified approximately $94,000 in cumulative missed and miscalculated depreciation deductions across the 8-year period.
Strategy 1: Form 3115 Filing to Correct Accounting Method
Under IRC Section 446(e), taxpayers can change their accounting method with IRS permission (or through automatic method changes under Revenue Procedures). We filed Form 3115 requesting a change from the client's simplified depreciation method to proper MACRS depreciation calculations.
The Form 3115 documented that: (1) Prior method was not in accord with IRC requirements; (2) New method (proper MACRS) complies with IRC Sections 168(c), 168(e), and 1016; (3) Catch-up adjustment of $94,000 would be calculated under IRC Section 481(c) with four-year spread.
This resulted in approximately $23,500 annual adjustment over four years, reducing taxable income and saving approximately $8,225 annually at the client's 35% marginal rate.
Strategy 2: Basis Adjustment for Capital Improvements
Over the 8-year period, the client had made significant capital improvements to the rental properties: new roofs ($42,000 total), HVAC replacements ($28,000 total), foundation repairs ($15,000 total), electrical system upgrades ($20,000 total). These improvements ($105,000 total) had been expensed in the year incurred rather than capitalized under IRC Section 1016(a)(1).
We amended the prior-year returns (Form 1040-X) to capitalize these improvements and begin depreciating them under proper MACRS schedules. This resulted in approximately $8,750 in additional cumulative depreciation deductions.
Strategy 3: Forward Depreciation Optimization and Section 179 Consideration
For future rental property acquisitions, we established a proper depreciation policy requiring: (1) Annual appraisals of basis allocation between land and building for each property; (2) Documentation of capital improvements with capitalization analysis; (3) Cost segregation studies for any future acquisition exceeding $250,000 basis.
Additionally, we reviewed Section 179 expensing eligibility for any equipment or fixtures used in the rental business (furnaces, water heaters, flooring). While residential rental properties themselves don't qualify for Section 179, personal property components within the buildings can be expensed under IRC Section 179(d) if acquired as part of a business property acquisition.
The Integrated Result
Direct catch-up benefit (8-year period): Form 3115 cumulative adjustment $94,000 + capitalized improvements adjustment $8,750 = $102,750 in recovered deductions, saving approximately $35,962 in federal tax (at 35% rate).
Spread over four years (IRC Section 481): Annual adjustment averaging $23,500, saving approximately $8,225 annually.
Forward depreciation optimization: By properly categorizing future capital improvements and using cost segregation for acquisitions > $250K basis, the client will avoid similar issues and capture maximum allowable depreciation going forward (estimated additional $4,200-$6,500 annually on any new acquisition).
Total benefit (Years 1-4): Approximately $94,000 in catch-up tax savings plus ongoing improved tax planning for forward years.
