Accelerating Depreciation: Shifting Tax Losses Into Year One
Standard IRS depreciation rules mandate that residential rental real estate be depreciated linearly over 27.5 years, while commercial property is spread over 39 years. Under standard straight-line methods, a high-value Bay Area property yields only a modest annual tax deduction.
A engineering-based Cost Segregation Study reclassifies building assets—carving out personal property (carpeting, specialty lighting, appliances) and site improvements (paving, landscaping, fencing) into 5-year, 7-year, and 15-year MACRS recovery periods. When paired with federal bonus depreciation rules, investors can front-load 20% to 30%+ of the total purchase price into immediate Year 1 tax write-offs. At Moontree Tax Service, we integrate cost segregation strategies directly into our rental property tax planning hub, serving commercial and multifamily investors across Los Gatos, Cupertino, and Campbell.
Real-World Example: $2M Multifamily Purchase
- The Purchase: An investor purchases a $2,000,000 multifamily property in San Jose (Land value: $400,000; Building value: $1,600,000).
- Standard Straight-Line Depreciation: $1,600,000 ÷ 27.5 years = ~$58,180/year deduction.
- With Cost Segregation Study (25% Reclassified to 5/15-Year Assets): $400,000 is reclassified into short-life property eligible for bonus depreciation.
- Year 1 Tax Loss: Combines short-life bonus depreciation with standard straight-line building write-offs to generate a ~$250,000+ Year 1 paper tax loss!
- The Impact: At the 37% federal tax bracket, this creates an immediate ~$92,500+ cash tax savings in Year 1.
California Franchise Tax Board (FTB) rules do NOT conform to federal bonus depreciation. While cost segregation generates massive bonus depreciation write-offs on your federal return (Form 1040 / 1065 / 1120-S), California forces MACRS straight-line calculations over shorter asset lives without bonus depreciation. We maintain separate federal and state asset depreciation schedules to keep your state tax returns fully compliant.

Engineering Study Coordination
We partner with leading engineering-based cost segregation firms to ensure asset allocations meet IRS Audit Technique Guide (ATG) standards and withstand scrutiny.
IRS Form 3115 Catch-Up Depreciation
Owned property for years without a study? We file Form 3115 (Application for Change in Accounting Method) to claim all missed historical depreciation in a single year—without amending prior tax returns.
REPS & W-2 Offset Pairing
We pair accelerated depreciation losses with our Real Estate Professional Status (REPS) advisory to allow paper losses to directly offset active W-2 tech salaries.
1031 Exchange & Recapture Exit Planning
Accelerated depreciation triggers Section 1245 and 1250 recapture taxes upon sale. We integrate cost segregation with our 1031 Exchange Tax Advisory to defer recapture tax permanently.
Integrating Accelerated Losses Across Your Profile
Generating substantial depreciation write-offs lowers overall household taxable income, keeping high earners in lower tax brackets during liquidity events.
If you are deploying vested stock options to fund commercial or residential purchases, we pair real estate depreciation with our specialized RSU cost basis adjustments and ISO AMT planning strategies during individual tax preparation. Operating an S-Corp or business? We connect real estate entities with our California AB 150 PTE tax services.
Frequently Asked Questions About Cost Segregation
What property purchase price makes a cost segregation study cost-effective?
Generally, properties with a building value (excluding land) of $500,000 or more generate enough tax savings to easily justify the cost of an engineering study. For properties with significant renovations or high-value residential/commercial units, smaller purchase prices may also qualify.
What happens to accelerated depreciation when I sell the property?
When you sell a property that underwent a cost segregation study, the accelerated depreciation taken on 5-year and 15-year assets is subject to Section 1245 depreciation recapture (taxed at ordinary income rates up to 37%). To prevent paying this recapture tax, most investors execute a 1031 exchange to defer the gain into replacement property.
Can I perform a cost segregation study on a property I bought 3 years ago?
Yes! This is called a “look-back cost segregation study.” By filing IRS Form 3115 (Change in Accounting Method), you can catch up on all the accelerated depreciation you would have claimed in prior years and take the entire cumulative deduction in the current tax year.
