Estimate your annual depreciation deduction on a rental property — and see how much a cost segregation study could accelerate into year one.
Estimates only, not tax advice. Straight-line depreciation assumes a full year in service; actual first-year depreciation is pro-rated by placed-in-service date. Cost-seg figures depend on your study; accelerated depreciation is recaptured on sale. Confirm with a qualified advisor.

STR tax calculator →Two dates, two different jobs.
The year you claim bonus depreciation is the year the property is placed in service — ready and available for rent. That is not necessarily the year you bought it, so a property purchased one year and first listed the next takes its deduction in the second year.
The rate you get is set by when you acquired it. 100% for property acquired after January 19, 2025. Property acquired on or before that date stays on the old phase-down, which is 20% for anything placed in service in 2026.
Acquisition is measured by the written binding contract, not the closing, and there is no election to opt into 100%.
