You should make sure that your accountant has the experience needed to allocate the components of the building. An engineered cost segregation study on a $1,000,000 building should result in $250,000 to $500,000 of the components being accelerated, providing tax savings that could range anywhere from $70,000 to $200,000. Identifying all of the building items that can legitimately be accelerated requires specialized construction and engineering expertise combined with in-depth knowledge of the tax laws, IRS rules and court cases governing cost segregation studies.
