Frequently Asked Questions
Cost Segregation Nationwide | The Ambrose Group
Qualifications
What types of properties qualify for a cost segregation study?
Commercial, industrial, multifamily, and investment residential properties generally qualify nationwide. Eligible activities include commercial ownership, construction, renovation, acquisition, and prior-year catch-up.
What are the cost thresholds for a cost segregation study?
A study makes the strongest financial sense for properties with $500,000 or more in acquisition or construction cost, or $200,000 or more in renovation or improvement expenditures. Properties below these thresholds may still qualify, request a free benefit analysis.
Can I still benefit if I bought my property years ago?
Yes. A 481(a) adjustment lets you capture all missed depreciation from prior years in the current tax year without amending past returns, using IRS Rev. Proc. 2011-14. This applies to qualifying properties in any state.
Can The Ambrose Group handle properties in multiple states?
Yes. Because cost segregation is federal, The Ambrose Group runs engineered studies across multi-state portfolios, making it a fit for owners and CPAs managing properties in several states from one provider.
Tax Benefits
What is cost segregation, and how can it benefit me?
Cost segregation is a federal tax strategy that identifies and reclassifies building components to accelerate depreciation deductions, increasing tax savings and cash flow. The Ambrose Group performs engineered cost segregation studies nationwide.
How does cost segregation reduce my tax liability?
By reclassifying components from 27.5- or 39-year schedules to 5-, 7-, or 15-year schedules, cost segregation accelerates depreciation deductions and reduces taxable income in the early years of ownership. The larger the Year 1 deduction, the more cash stays available to reinvest.
How does bonus depreciation interact with a cost segregation study?
Bonus depreciation allows eligible short-lived assets identified in a study to be fully deducted in the year they are placed in service. The One Big Beautiful Bill Act of 2025 permanently restored 100% bonus depreciation for qualified property acquired and placed in service after January 19, 2025. Confirm how it applies to your tax year with your CPA.
What kind of first-year tax savings can I expect?
Results vary by property type, cost basis, construction year, and applicable depreciation rates. The Ambrose Group offers a free benefit analysis so you can see projected savings before committing. As a reference point, a $2.9M commercial property engagement delivered $657,692 in first-year depreciation increase and $230,192 in first-year tax savings.
IRS Compliance & Audit
Will a cost segregation study trigger an IRS audit?
No, not when the study is properly engineered and documented. The Ambrose Group follows the IRS Cost Segregation Audit Techniques Guide (ATG) on every engagement, and every study includes full audit support and documentation designed to withstand IRS scrutiny.
Why does it matter that The Ambrose Group uses an in-house engineer?
The IRS prefers engineering-based studies over rule-of-thumb estimates. The Ambrose Group’s in-house engineer conducts the analysis, reviews construction documents, and physically identifies reclassifiable components, producing a defensible, documented study. Many providers estimate; we don’t. This methodology applies to every study nationwide.
What is the IRS Cost Segregation Audit Techniques Guide?
The IRS Cost Segregation Audit Techniques Guide (Publication 5653) is the IRS’s published examiner guidance for reviewing cost segregation studies, covering methodology, documentation standards, and asset classification criteria. It is the industry’s primary reference for compliant, defensible studies, and The Ambrose Group adheres to it on every engagement.
What happens if the IRS audits my cost segregation study?
The Ambrose Group provides full audit support with every study, in any state. If the IRS reviews your study, our team provides documentation, responds to inquiries, and supports your CPA through the process.
Getting Started
How do I get started with a cost segregation study?
Request a free benefit analysis. The Ambrose Group reviews your property and estimates your potential first-year depreciation and tax savings before you commit to a study.
How much does a cost segregation study cost?
Fees vary by property type, size, and complexity. Most owners recover the cost of the study many times over in first-year tax savings, often the same filing. The Ambrose Group provides a free benefit analysis before any engagement so you can see projected savings first.
How does The Ambrose Group work with my CPA?
The Ambrose Group works alongside your CPA not around them. We deliver a CPA-ready report with all reclassification data, asset schedules, and supporting documentation so your tax advisor can apply the results directly.
What happens if the IRS audits my cost segregation study?
