Estimates only, using typical reclassification ranges for each property type and simplified first-year conventions. Actual results depend on an engineering study, your tax position (including passive activity rules) and state taxes. Not tax advice.

How this estimate works

A Cost Segregation study moves parts of a building from 27.5- or 39-year Depreciation into 5-, 7- and 15-year property. This calculator uses a typical percentage reclassified for each property type, applies the Bonus Depreciation rate for the year you bought it, and compares the first-year deduction with standard straight-line Depreciation.

For a precise figure, an Engineering-based study reviews your actual construction costs, drawings and site. Read: Is Cost Segregation worth it?
