Offset active income with real estate depreciation strategies.
A cost-segregation study breaks a building into its faster-depreciating parts, pulling years of deductions forward into early ownership. Paired with the right tax posture, those deductions can shelter the property's cash flow — and, for qualifying investors, offset active income earned outside the portfolio.
Decades of deductions, pulled into the early years
Commercial and residential rental buildings are depreciated over decades by default — 39 years for commercial, 27.5 for residential. But a building is not one thing. Inside it are components with much shorter recovery periods: fixtures, certain wiring and plumbing, flooring, cabinetry, specialized electrical, and land improvements like paving, landscaping, and site lighting. A cost-segregation study identifies and reclassifies those components into 5-, 7-, and 15-year buckets.
The effect is timing. The total depreciation is the same over the life of the asset, but cost segregation moves a large share of it into the first years of ownership — exactly when the deductions are most valuable and most useful for sheltering cash flow. When combined with bonus depreciation, a meaningful portion of those reclassified components can be deducted in the very first year.
For investors with substantial active income, this is where it gets powerful. Depending on your tax status and whether you materially participate, the losses generated by accelerated depreciation may offset income from a business or profession — not just passive rental income. That outcome is governed by real-estate-professional status, material-participation tests, and passive-activity rules, and it is not automatic. It has to be planned. This is general information, not tax advice; your CPA should confirm how it applies to you.
- You've recently acquired, built, or renovated a property
- The building has significant reclassifiable components
- You have rental cash flow or active income to shelter
- You qualify, or could qualify, for active-income treatment
- You're planning a larger acquisition program
How cost segregation creates value
Component reclassification
An engineering-based study separates the building into 5-, 7-, and 15-year components from the standard 27.5- or 39-year shell.
Accelerated deductions
Depreciation shifts into the early years of ownership, increasing deductions when they matter most to after-tax cash flow.
Bonus depreciation stacking
Reclassified short-life components become eligible for bonus depreciation, deducting a large share of cost in year one.
Active-income offset
For investors meeting status and participation rules, the resulting losses may offset active income earned outside the portfolio.
Look-back studies
Studies can capture missed depreciation on properties already owned, catching up the benefit without amending prior returns.
Defensible documentation
A proper engineering study produces the documentation to support the position — the difference between an aggressive number and a defensible one.
How we work it into a deal
Screen the opportunity
We estimate the likely benefit against the cost of a study and your tax posture, so the analysis only proceeds where it genuinely pays.
Commission the study
We coordinate an engineering-based study with qualified specialists and your CPA so the reclassification is both maximized and defensible.
Underwrite the after-tax return
We fold the accelerated deductions into the deal model so you're investing against a real after-tax return, not a pre-tax one.
Why it ties into the deal
- Front-loaded deductions improve early after-tax cash flow
- Stacks with bonus depreciation for a larger year-one benefit
- May offset active income for qualifying investors
- Look-back studies recover depreciation on assets you already own
- We underwrite the after-tax return, not the headline yield
- Documentation built to support the position with your CPA
