Cost Segregation Study
A full engineering-based analysis of your dealership property that reclassifies assets into 5-, 7-, and 15-year depreciation schedules — unlocking significant first-year deductions and improving cash flow.
Auto dealerships are complex properties with showrooms, service bays, parts storage, and outdoor lots — each component carrying unique depreciation potential. Seneca Cost Segregation's engineering-based studies help dealership owners reclassify assets, accelerate deductions, and unlock substantial first-year tax savings. Discover how much your dealership property could be worth in recovered cash flow.

Comprehensive cost segregation solutions designed to maximize tax savings and accelerate depreciation for auto dealership property owners.
A full engineering-based analysis of your dealership property that reclassifies assets into 5-, 7-, and 15-year depreciation schedules — unlocking significant first-year deductions and improving cash flow.
Already own your dealership property? Claim missed depreciation from the past 15 years using IRS Form 3115 — no amended returns required — and receive all missed deductions in a single tax year.
Skip the disruption of on-site visits. Our engineers conduct a thorough 30–45 minute video call inspection of your dealership, delivering faster turnaround in 2–3 weeks at a lower overall cost.
Every study includes Seneca AuditDefense at no extra charge. If the IRS questions your cost segregation findings, our team handles all inquiries and documentation for as long as you own the property.
We work directly with your accountant to ensure seamless integration of depreciation schedules into your tax returns, including support for Form 3115 filings and look-back study implementation.
Beyond cost segregation, we identify additional tax-saving opportunities across your dealership portfolio, partnerships, and business structure at no additional charge.

We start with a no-cost consultation to assess your dealership property's eligibility, estimate potential tax savings, and provide a transparent ROI analysis. Dealership properties — with their showrooms, service bays, lot lighting, and canopies — often yield exceptional reclassification opportunities.

Cost segregation is an IRS-approved tax strategy that reclassifies components of your dealership property — such as service bay equipment, lot lighting, canopies, paving, and HVAC systems — into shorter 5-, 7-, or 15-year depreciation schedules instead of the standard 39 years. This accelerates deductions and delivers substantial cash flow in the first years of ownership.
