Explore a stated scenario or use figures reviewed with your tax preparer. The calculator does not decide whether you qualify for a deduction.

1. Your rental

The simple estimate assumes one wholly rented residential property, a 27.5-year GDS building, one placed-in-service date for all components, and continued ownership and full rental use through the modeled year. The baseline excludes faster depreciation or expensing already claimed or available without buying a study. It excludes personal-use conversions, gifts, exchanges, self-construction, separate improvement dates, ADS, and previously separated or expensed assets. Use preparer-supplied figures for those cases.

20% and 5% are illustrative assumptions from one provider's published example. Your study gives the supported allocations.

2. Model use of the additional deduction Choose an illustration or use your preparer's amount
3. Tax rate and costs

An educational scenario, not a cost segregation study, eligibility determination, or tax return. Federal only. It excludes the tax treatment of fees, changing tax rates, state rules, later deductions, and sale effects. Entered values are used locally; this calculator does not transmit them or write them to storage.
