Cost Segregation Studies are our Specialty
A cost segregation study is an engineering-based analysis of building components and costs. It identifies and values all components of a property and allocates the actual total cost of the property based on those values. Typical building components that are allocated to 5-year or 7-year personal property include carpet; decorative trim; specialty lighting, electrical and plumbing components; certain cabinetry; appliances; and furnishings. Typical 15-year land improvements identified in a cost segregation study include paving, sidewalks, curbing, storm water drainage systems, flagpoles, and mailbox structures.
Cost segregation is not limited to new acquisitions of property. If a building was placed in service any time after 1986, and a better allocation could have been made, the IRS allows the owner to file a Change in Accounting Method to recover any missed depreciation from all prior years. This catch-up adjustment can be made on the current year’s tax return, and no amendments are required. The adjustment is often hundreds of thousands of dollars, and sometimes more. A cost segregation study can create ordinary tax deductions and can be performed up until the year of a property’s sale.
By accelerating depreciation deductions, you reduce your taxable income in the early years of property ownership, when cash flow is crucial. The value of saving tax now rather than later can be measured by the net present value at a rate of return you get from the use of your cash now. You may be able to reduce your debt and interest expenses, or you may be able to invest the additional cash flows into new income-earning ventures. Years with eligibility for bonus depreciation significantly increase the benefits of cost segregation.
