Vault infrastructure, security systems, pneumatic tubes, and drive-through structures create a unique cost segregation profile that standard office studies never capture.

Bank buildings are specialized structures — and that specialization creates a cost segregation opportunity that goes well beyond standard commercial office.
The vault is the starting point. A bank vault is one of the most expensive single elements in a financial facility — and the vault door, vault liner, currency equipment, and specialized electrical serving the vault are personal property in the IRS sense.
The security and surveillance system in a full-service bank is extensive: cameras throughout, access control at every sensitive zone, alarm systems, and the network infrastructure supporting all of it. Every component is 5-year personal property.
Drive-through canopy structures, teller counter infrastructure, safe deposit box systems, and pneumatic tube systems add additional personal property beyond what standard office buildings produce. For a $5 million bank branch, the combination typically yields a reclassification rate of 25–38%.
These are the IRS-verified asset classes under Rev. Proc. 87-56 and supporting case law — confirmed across 16,000+ studies. Every component is documented to its correct recovery period with engineering justification, defensible under IRS examination.
Cost Seg America engineers bank building cost segregation studies with direct analysis of vault infrastructure, security systems, and drive-through components — the elements that make a financial institution categorically different from a standard commercial office building. Vault door and liner systems, teller counter infrastructure, safe deposit box systems, and pneumatic tube networks are 5-year personal property under IRS classification rules. Our engineering team documents every financial infrastructure component to its correct recovery period.
The IRS publishes a 347-page Audit Technique Guide on cost segregation. It identifies Approaches 1 and 2 as the preferred methodologies. Studies priced under $2,900 recover $60,000–$150,000 less per $1 million of depreciable basis than a fully engineered study. Cost Seg America has used IRS Approaches 1 and 2 on every study for 24 years. 125+ IRS audits. Zero losses. $0 ever returned. The methodology is why.
Cost segregation is an IRS-approved engineering analysis that reclassifies components of your bank property from the default 39 yr straight-line depreciation schedule to three shorter recovery periods: 5-year personal property, 7-year personal property, and 15-year land improvements. Every component that qualifies for an accelerated schedule is individually identified, measured, and documented — not estimated from an industry average.
With 100% bonus depreciation active under the One Big Beautiful Budget Act (OBBBA) for property placed in service after January 19, 2025, every qualifying 5-year, 7-year, and 15-year component can be fully deducted in Year 1. Cost Seg America consistently recovers $60,000–$150,000 more in deductions per $1 million of depreciable basis than studies priced under $2,900.
The typical reclassification rate for bank is 25–38% of the depreciable basis. On a $5M property, this translates to approximately $473,600 in Year 1 federal income tax savings at a 37% rate. Actual results vary based on the specific property, construction type, and individual tax situation.
The One Big Beautiful Budget Act (OBBBA) restored 100% bonus depreciation for qualified property placed in service after January 19, 2025. With 100% bonus depreciation, every qualifying 5-year, 7-year, and 15-year component identified in your study is fully deductible in the year you place the property in service. The entire deduction lands on your return in Year 1. Your CPA determines your eligibility based on your individual tax situation, passive activity rules, and other factors.
Yes. The IRS allows you to go back and claim deductions you never took on prior-year properties using a Form 3115 change in accounting method — without amending previous returns. The catch-up deductions are taken entirely in the current tax year. Cost Seg America applies lookback analysis as standard practice. We partner with a trusted CPA specialist who handles the Form 3115 filing.
Cost Seg America's minimum qualifying property value is $200,000. Below this threshold, the engineering cost typically exceeds the tax benefit. Above $200,000, the fee-to-benefit ratio is consistently favorable and grows substantially with property value.
Unlimited audit defense means if the IRS examines your cost segregation study — this year, five years from now, or ten years from now — Cost Seg America responds. Written responses and phone representation. No time limit. No hour cap. No additional fee. Ever.
In 24+ years and 125+ IRS audits, Cost Seg America has never lost an audit and has never returned a dollar to the IRS.
Cost Seg America doesn't just find the deductions — we document them to survive the most demanding IRS examination.
