Cost Segregation Studies

Accelerate depreciation deductions and maximize cash flow from commercial and residential rental properties through engineering-based cost segregation analysis. A powerful tax strategy for real estate investors and property owners.

Unlock Hidden Tax Savings in Your Property

A cost segregation study is an engineering-based analysis that reclassifies components of commercial or residential rental property into shorter depreciation categories. Instead of depreciating the entire building over 27.5 or 39 years, a properly conducted study identifies personal property (5, 7, and 15-year assets) that can be depreciated on an accelerated basis — generating significant upfront tax deductions and improving cash flow.

The IRS has consistently upheld the validity of cost segregation studies when performed by qualified professionals. The Tax Cuts and Jobs Act and subsequent legislation have made this strategy even more powerful through bonus depreciation provisions, allowing eligible property components to be fully expensed in the year they are placed in service.

How Cost Segregation Works

Our team works with qualified engineers and construction professionals to conduct a detailed analysis of your property. The study identifies building components that qualify for shorter depreciation lives under the Modified Accelerated Cost Recovery System (MACRS).

  • Structural components (walls, roof, foundation) remain at 39-year or 27.5-year life
  • Land improvements (parking lots, landscaping, sidewalks) reclassified to 15-year property
  • Personal property (specialized electrical, plumbing, cabinetry, flooring) reclassified to 5 or 7-year property
  • Qualified Improvement Property (QIP) eligible for 15-year depreciation and bonus depreciation

Who Benefits from Cost Segregation?

Cost segregation studies are valuable for property owners across a wide range of real estate types. The strategy is most impactful when the property has a significant construction or acquisition cost and the owner has sufficient taxable income to absorb the accelerated deductions.

  • Commercial office buildings and retail centers
  • Multi-family apartment complexes and rental properties
  • Hotels, restaurants, and hospitality properties
  • Industrial facilities and warehouses
  • Medical and dental offices
  • Self-storage and flex-space facilities
  • New construction, acquisitions, and renovations

Bonus Depreciation & Section 179

Recent tax legislation has significantly enhanced the value of cost segregation studies. With 100% bonus depreciation restored, property components with recovery periods of 20 years or less can be fully expensed in the year placed in service. This creates substantial first-year deductions that dramatically improve after-tax returns on real estate investments.

When combined with Section 179 expensing and strategic tax planning, cost segregation becomes one of the most powerful tools available to real estate investors and business property owners for managing their tax liability.

Lookback Studies

Already own property that you've been depreciating on a straight-line basis? A lookback cost segregation study allows you to capture the benefit of accelerated depreciation on previously placed-in-service property without amending prior-year returns. By filing a Form 3115 (Change in Accounting Method), you can claim the cumulative “catch-up” deduction in the current tax year — a powerful strategy for properties acquired in prior years.

Our Approach

We coordinate with qualified engineering firms to deliver comprehensive, audit-defensible cost segregation studies. Our role goes beyond simply ordering a report — we integrate the study results into your overall tax strategy, model the impact on current and future tax years, and ensure proper reporting on your returns.

  • Pre-study feasibility analysis to confirm ROI before engagement
  • Coordination with experienced engineering teams specializing in cost segregation
  • Detailed review and quality control of the engineering report
  • Integration with your annual tax preparation and multi-year planning
  • Guidance on bonus depreciation elections and Section 179 optimization
  • Lookback study analysis and Form 3115 filing when applicable
Decision Support

Cost segregation only works when the study file is defensible

The decision is not just whether accelerated depreciation is available. It is whether the property facts, passive activity profile, placed-in-service dates, and source documents support the tax result.

Who This Is For

  • Owners of commercial, multifamily, rental, or short-term rental property.
  • Investors with acquisitions, renovations, buildouts, or lookback studies.
  • Real estate clients modeling bonus depreciation and cash-flow impact.

Documents Usually Needed

  • Closing statement, appraisal, settlement detail, and property records.
  • Construction invoices, improvement detail, and fixed asset schedules.
  • Placed-in-service dates, depreciation history, and entity ownership records.

What You Receive

  • Study-readiness review and document request before engagement.
  • Depreciation, bonus, and cash-flow modeling tied to your tax posture.
  • Implementation notes for return reporting and multi-year planning.

When Timing Matters

  • After acquisition or placed-in-service and before filing the return.
  • After major renovations when asset classes and dates need support.
  • Before sale, refinance, or year-end planning that depends on deductions.

Common Mistakes

  • Focusing only on first-year deductions instead of total tax impact.
  • Ignoring passive loss limits, recapture, state rules, or land allocation.
  • Using a study without maintaining the underlying source file.

Engagement Fit

  • Best fit when tax capacity and documentation support the benefit.
  • Engineering study coordination is paired with CPA tax integration.
  • Scope is set after reviewing property, records, and planning goals.
Source-Backed Notes

Cost segregation needs a defensible study file

The tax benefit is only as strong as the property classification, placed-in-service records, allocation method, and source documents behind the study.

Bottom Line

Who should consider a cost segregation study?

Short answer: Real estate owners, investors, and operators should consider cost segregation when they acquire, build, renovate, or improve rental or commercial property and want to accelerate depreciation deductions.

  • Commercial, multifamily, short-term rental, and residential rental properties.
  • Depreciation planning tied to bonus depreciation and tax strategy.
  • Cash-flow analysis for owners who can use accelerated deductions.
