When acquiring, renovating or building real estate, most taxpayers tend to overstate the amount of 39-year real property. This limits the depreciation deductions available to taxpayers in the early stages of their investment. A cost segregation solves this problem by reclassifying assets by maximizing the property eligible for treatment as 5-, 7- or 15-year property. This depreciation optimization frees up substantial cash flow.


Ernst & Morris (founded in 1993) and McGuire Sponsel have joined forces. This merger, formed by choice and opportunity, brings two of the most trusted consulting firms together. See News Release Here

Case Study

Commercial Office Portfolio

The professionals at McGuire Sponsel performed a cost segregation study on a $195 million portfolio of office buildings located in Arizona, Florida, Tennessee, Texas, and Washington D.C. Our specialists physically inspected the properties, tenant listings, and general ledgers to optimize depreciation and partially disposed assets. The result was a $9.4 million increase to the first year cash flow.


MOTW: Episode 16

On this week’s episode Dave explains the 179D deduction and why after being in limbo for the past 2 years building owners are looking at the deduction for tax planning purposes.

White Papers

Leasehold Improvements & Depreciation

For the last few years the IRS has allowed for certain leasehold improvements to receive special treatment for depreciation. While rooftop or outdoor HVAC units are not eligible for this treatment, the IRS confirmed HVAC units located inside a building and feeding tenant areas are eligible for 15-year treatment and bonus depreciation. This confirms the position McGuire Sponsel has taken for our clients.
