Reasons Why USTAGI Is the Perfect Cost Segregation Partner for CPAs
As a CPA, you already know that cost segregation is one of the most powerful tax tools available to real estate investors today. With 100% bonus depreciation permanently restored for property placed in service after January 19, 2025, the timing advantage has never been greater. A well-executed study can accelerate tens or even hundreds of thousands of dollars in deductions, dramatically improving your clients' cash flow and your own value as their trusted advisor. But here's the challenge: not all cost segregation studies are created equal. And referring your clients to the wrong provider might leave money on the table. That's where USTAGI (US Tax Advisors Group, Inc.) comes in.
Industry analysts and CPA reviewers consistently highlight several critical factors when evaluating cost segregation providers. USTAGI delivers on every count.
1. Engineering-Based Methodology
The IRS Audit Technique Guide makes it clear: the only approach that consistently withstands scrutiny is the detailed engineering approach from actual cost records: a thorough review of construction blueprints, invoices, and capital expenditure records, combined with a detailed on-site examination of the property and a line-item breakdown of assets into correct depreciation categories.
CPAs should avoid firms that rely on estimates or residual methods. These generic, cookie-cutter reports are the first thing an IRS agent will eviscerate during an audit.
USTAGI's engineers actually inspect every part of the property. With their boots on the ground, they are constantly examining exact flooring materials, lighting fixtures, specialized electrical runs, wall coverings, and cabinetry. Our specialists document everything with photos and measurements, tying every component directly to your client's specific construction records. With nearly 20 years of experience and over 20,000 studies completed, the process is tested, refined, and efficient.
2. IRS-Aligned Documentation That Stands Up to Audit
A quality cost segregation study is defined by the documentation behind them. CPAs need clear, defensible workpapers that allow them to confidently file returns and plan for future liabilities. To meet the standards of the IRS investors must present a comprehensive report that includes detailed engineering analysis, organized depreciation schedules, cost reconciliation workpapers proving all numbers tie back to the purchase price, Form 3115 preparation for look-back studies, and a narrative explaining the analysis methods and legal reasoning behind every classification decision.
USTAGI provides all of this with each study. We meet the highest industry standards, ensuring compliance and audit readiness. One CPA put it this way:
"I'm a tax CPA. Had my first real estate client, who bought a 15-year-old medical office building. I kept hearing about cost seg from a colleague, so we hired USTAGI to run a study. Honestly, they delivered about $220k catch-all depreciation in year one. Client was thrilled, and it made my year-end planning look great. I can't complain about the results. I have hired them again after that for most of my clients."
3. Audit Defense Included
Some firms charge an additional 10% to 30% premium just to stand behind their own work if the IRS comes calling. Others advertise "audit support" but quietly limit it to a set number of hours, a short window after delivery, or charge additional fees when the IRS actually opens a file. Any provider that charges extra for audit defense or is vague about what their support actually covers is a risk. The true test of a firm's confidence and service is audit defense support.
When you buy a study from USTAGI, you're buying a defensible, technically rigorous document prepared with the expectation that the IRS could review it, but we’ll also be there to defend it. No hidden fees. No fine print.
4. Real Estate Specialization Across All Property Types
CPAs tend to look for a partner with a deep portfolio in their client's specific property type. They will know where to look for hidden savings and understand the common audit triggers for that industry. USTAGI specializes in studies across the entire real estate spectrum: modest single-family rentals, large-scale commercial portfolios, multi-unit apartment complexes, retail centers, medical facilities, hotels… They tailor each analysis to the specific asset to unlock the highest possible deductions.
5. Transparent, Fixed Pricing
A reputable firm will charge a transparent, flat fee for its services. USTAGI doesn’t rely on percentage-of-savings arrangements, there are no surprises. We deliver studies at competitive prices —often for under $1,000— because we want to make cost segregation accessible to clients at every level.
6. Certified Cost Segregation Professional (CCSP) Credentials
The most critical credential to look for is the Certified Cost Segregation Professional (CCSP), administered by the American Society of Cost Segregation Professionals (ASCSP). This certification requires a minimum of 7 years and 7,000 hours of direct experience. Ask potential partners to explain their methodology in detail whenever you consider hiring for your property. If it doesn't center on engineering principles, it's a major red flag because it may be a sign that you’re not working with certified specialists.
USTAGI was founded by the CSP Joseph Viery, who has been a Certified Cost Segregation Professional since 2007. The entire team operates at the highest professional standards, significantly increasing the defensibility of every study in the event of an IRS review.
Earn While You Help Your Clients
USTAGI recognizes that CPAs are the gatekeepers of smart tax strategy. You're the one who sees your clients' financial picture, identifies opportunities, and recommends solutions. While working on reports, we usually strategize with the CPAs of our clients, because we value the quality of our work, and we know that a tax strategy is the most effective when it’s developed with a coordinated effort. This is also the reason why USTAGI has built a CPA affiliate program designed to reward you for the referrals you're already making. The process is simple:
Refer your clients to USTAGI for a professional cost segregation study.
Your clients get a high-quality, IRS-defensible study at a competitive price.
You get compensated for every successful referral.
Best of all, referring to USTAGI enhances your value as a trusted advisor. Beyond preparing returns, you're proactively identifying tax-saving strategies that your clients may not even know exist.
The program is designed to be hands-on or hands-off depending on your preference. You choose how involved you want to be. Some CPAs prefer to simply make the introduction and let USTAGI handle everything from consultation to delivery. Others want to stay closely involved throughout the process.
For CPAs who want to go a step further, USTAGI offers a white-label version of their cost segregation services. This allows you to offer cost segregation studies to your clients under your own brand, without needing in-house engineering expertise. Think of it as private-label cost segregation: USTAGI performs the engineering analysis, site inspection, and report preparation, but your firm's name and logo appear on all deliverables, you set the pricing and manage the client relationship. Your clients never need to know about the partnership, they see you as the provider. This is an ideal solution for CPA firms that want to expand their service offerings, increase recurring revenue, and deepen client relationships without the overhead of hiring engineers or building a cost segregation practice from scratch.
