MANUFACTURING FACILITIES

Much of Your Manufacturing Facility Can Be Recovered in Year One Instead of Spread Over 39 Years.

Manufacturing equipment qualifies as 7-year property. There is often far more of it embedded in your facility than your accountant has ever documented.

UNDERSTANDING THE OPPORTUNITY

Why Manufacturing Is a Cost Segregation Opportunity.

Manufacturing facilities sit at the intersection of real property and personal property — and most investors, operators, and accountants never fully map where one ends and the other begins.

The building shell is real property: 39-year depreciation. But embedded in that building is a layer of production infrastructure the IRS classifies as personal property: electrical systems dedicated to production processes, compressed air distribution, process piping, specialized ventilation for manufacturing operations, and the infrastructure directly tied to production machinery.

Manufacturing and process equipment qualifies as 7-year personal property. A manufacturing facility with $20 million in total property value may have $6–10 million in 7-year and 15-year assets — assets that can be fully deducted in Year 1 under current bonus depreciation rules.

Without a cost segregation study, all of that defaults to 39 years.

💡 The Teaching Moment
Manufacturing equipment and process machinery qualify as 7-year property — not 5-year. This is one of the most important IRS classifications in manufacturing cost segregation and one of the most frequently misclassified in software-based studies.

Cost Seg America recovers $60,000–$150,000 more in deductions per $1 million of depreciable basis than studies priced under $2,900 — because our team counts every single component in your building instead of applying industry averages. 125+ IRS audits. Zero losses. $0 ever returned.
METHODOLOGY

The IRS Named a Preferred Methodology. We Use It on Every Study.

Cost Seg America engineers manufacturing facility cost segregation studies with correct classification of process equipment as 7-year personal property — not building components. This distinction is one of the most consequential in manufacturing cost segregation and one of the most frequently misclassified in software-based studies. Our engineering team identifies every process system, every dedicated electrical circuit, and every equipment foundation to its proper IRS 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.

IRS Approach 5 — Industry Average Modeling
  • Software modeling using industry cost factors — not your actual building
  • 5-year and 7-year components estimated, not individually counted
  • No component-by-component engineering documentation produced
  • The IRS Audit Technique Guide identifies Approaches 1 & 2 as preferred
  • Studies under $2,900 recover $60,000–$150,000 less per $1M
  • When examined, there is no engineering record behind the numbers
Cost Seg America — IRS Approaches 1 & 2
  • Every 5-year and 7-year component individually counted, measured, and valued
  • Direct cost identification from your actual construction records and plans
  • Engineering documentation for every IRS classification — component by component
  • 125+ IRS audits — every classification examined and upheld
  • Zero losses — $0 ever returned to the IRS
  • Written responses & phone representation — no time limit, no hour cap, no additional fee, ever

FREQUENTLY ASKED QUESTIONS

Manufacturing Cost Segregation — Questions & Answers.

What is cost segregation and how does it work for manufacturing properties?+

Cost segregation is an IRS-approved engineering analysis that reclassifies components of your manufacturing 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.

With 100% bonus depreciation active under 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.

What is the typical reclassification rate for manufacturing?+

The typical reclassification rate for manufacturing is 40–65% of the depreciable basis — the highest of any property type, driven by process equipment classified as 7-year personal property. On a $20M property, this translates to approximately $3,530,000 in Year 1 federal income tax savings at a 37% rate.

How does 100% bonus depreciation change the math on a manufacturing property?+

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. Your CPA determines your eligibility based on your individual tax situation, passive activity rules, and other factors.

Can I do a lookback study on a manufacturing property I already own?+

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.

What is the minimum property value to qualify?+

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.

What does unlimited audit defense mean — is it really included?+

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.
