Auto Dealership
Dealership cost segregation: $300K–$1M Year-1 deductions.
A dealership stacks two of the biggest reclass levers in real estate: a massive paved display/inventory lot (15-year land) and heavy service + body-shop equipment (5/7-year) — most of it buried on the 39-year schedule.
The 30-second answer
Auto-dealership cost segregation is an engineering-based study that reclassifies a dealership's components out of the default 39-year commercial schedule into faster 5-, 7-, and 15-year MACRS classes. It fits franchise, used-car, RV, boat, and powersports dealers, because a dealership stacks two unusually large reclass levers: a paved display/inventory lot (a store sits on ~4x its building footprint in paving + high-mast lighting, all 15-year land improvements and usually the single biggest line) and heavy service + body-shop equipment (vehicle lifts, paint booth, alignment racks, compressed air — 5/7-year personal property). That matters because, with 100% bonus depreciation, the reclassified amount (about 30% on the building and lot alone, and ~48% with a large lot and documented equipment) is deductible in Year 1.
Dealership cost segregation reclassifies 30–48% of depreciable basis from the 27.5- or 39-year shell into 5-, 7-, and 15-year MACRS classes per 26 U.S.C. § 168 and Rev. Proc. 87-56. Under OBBBA's permanent 100% bonus depreciation (placed-in-service 2025+), reclassified components are deductible in year one. All credible cost-seg providers use the same federal framework — industry-standard 2026 construction cost data, MACRS classification, IRS Audit Techniques Guide (Pub 5653) compliance. What differs across property types is land-allocation share, FF&E weight, and material-participation eligibility under §469.

Real examples
What dealership cost seg looks like in practice.
Estimates assume 37% federal bracket and full first-year usability of the loss (active income offset or REPS). Your actual benefit varies with bracket, basis allocation, and CPA's treatment.
Good fit when…
- ✓Owners who bought or built a dealership on a large paved lot
- ✓Stores with a service department or body shop (documented equipment → observed 5/7-yr)
- ✓Franchise, used-car, RV, boat, motorcycle, and powersports dealers
Skip it when…
- ×A bare leased shell with no owned lot or equipment basis
- ×Basis under ~$1M, where the study fee gets thin against the benefit

Frequently asked
Dealership cost segregation, by question.
Do auto dealerships qualify for cost segregation?
Yes — one of the densest commercial types. The paved display/inventory lot + high-mast lighting are 15-year land improvements (usually the biggest line), and the service/body-shop equipment (lifts, paint booth, alignment racks) is 5/7-year. A typical store reclassifies 30%+ on the building and lot alone, more when equipment is documented.
Why is the display lot such a big deal?
A dealership sits on ~4x its building footprint in paved lot. That paving + lot lighting is 15-year property and usually the single biggest reclassification line — and our model scales it to your actual lot size. Bigger lot, bigger deduction.
How much does a dealership study cost?
Priced as standard commercial: from $1,995 for sub-$1M basis, $3,295 for a $1M–$3M store, and $7,795 for a $7M–$10M store, delivered CPA-ready in under an hour. No site visit.
Does it work for used-car, RV, and powersports lots?
Yes. A used-car lot is mostly the paved lot + a small office, so the 15-year site-work lever dominates. RV/boat/powersports dealers have the same showroom + service + huge lot profile. The study flexes to each.
