Know What You’re Buying
The Cheapest Study Usually
Costs You the Most.
They sold you a study. We would have found you a fortune.
The IRS recognizes six methodologies. The one your firm uses determines how much you find — and what happens if the IRS ever opens the file. Most low-cost studies use Approach 5. Here is exactly what that means for you.
⚠ IRS Approach 5 — The Cheap Study
 Software Modeling Approach
Industry Percentages Applied to Your Building’s Total Cost
Often priced under $2,500. Processed in volume. Frequently outsourced overseas.
Software model generates component values — your property never directly analyzed
Frequently outsourced overseas — processed in volume with minimal individual attention
No direct analysis means no real documentation — exactly what the IRS asks for first
On a $2M building — $120,000 to $300,000 in deductions permanently missed
Audit defense often capped, time-limited, or costs extra
The study cost you less. The deductions it missed cost you more.
 Cost Seg America
Individual Engineering on Every Component. Every Building.
IRS Approaches 1 & 2. Every property directly analyzed. 100% U.S.-based team.
Every component individually identified, measured, and valued on your specific property
100% in-house, U.S.-based team — the same analysts who do the work defend the work
IRS calls Approaches 1 & 2 “the most methodical and accurate” — our standard on every study
Every component counted — both qualifying and non-qualifying — nothing left behind
Unlimited audit defense — no caps, no time limits, no extra charge. Ever.

The question is never which study costs less. It’s which study costs you the least. A thorough study pays for itself many times over in the deductions a software model quietly leaves behind.

Tax Savings and Cash Flow Benefits

The primary advantage of a cost segregation study is the acceleration of depreciation expense, which leads to considerable tax savings. By reclassifying building assets into shorter life categories, you can claim larger deductions in the earlier years of property ownership, optimizing your taxable income and cash flow. For instance, investors often use these savings to reinvest in new properties or enhance operational liquidity. At Cost Seg America, our clients consistently realize optimized cash flow positions that empower stronger financial planning and investment growth.

When to Perform a Cost Segregation Study

Cost segregation studies are particularly beneficial during property acquisition, new construction, renovation, or expansion phases. Initiating a study early allows for maximum tax benefit capture from day one. However, even properties held for several years can benefit through retroactive studies using IRS Form 3115 to adjust depreciation schedules. Business owners and CFOs focusing on tax efficiency should consider engaging a professional study tailored to their assets’ specifics. Cost Seg America provides expert guidance and offers free customized proposals to explore your savings potential.
