How the Estimate Works

The calculator applies a low and high reclassification assumption to the depreciable building basis. It estimates first-year depreciation on that short-life basis using the bonus percentage you enter plus a 15% blended first-year MACRS assumption on the remaining short-life basis. It compares that amount with straight-line building depreciation.

The result is a range, not a quote or tax opinion. It does not model passive-activity loss limits, real estate professional status, the short-term rental material-participation rules, state depreciation adjustments, interest limits, at-risk limits, recapture, or time value of money. A study determines classification; a tax advisor determines how the deduction fits your return.

What to Do Next

Gather the closing statement, land allocation, depreciation schedule, placed-in-service date, renovation costs, and any construction drawings. Browse the property type guides, then use the estimate to frame a discovery call.
