Cost Segregation

Accelerate your depreciation

See how a cost segregation study reallocates your basis into 5-, 7-, 15- and 27.5/39-year classes — and what that does to your first-year deduction. Built on IRS MACRS tables (Pub. 946). A simulator, not a verified study.

Property data
Total acquisition price of the property, before closing costs.
The portion attributable to land — it can't be depreciated. Default ~20%; use your county assessor ratio for accuracy. Auto-set to 20% of price (placeholder) · verify with your county assessor or appraisal.
Money spent on improvements/remodeling. Added to the depreciable base — much of it can qualify for 5/7/15-yr classes and bonus.
Used together with your income to find your federal bracket. Rates and thresholds differ by status.
Taxable income = gross income minus deductions. 2026 standard deduction: $16,100 single · $32,200 joint · $24,150 head of household. We use this to set your marginal rate automatically. A large deduction can push part of your income into a lower bracket, so real savings may be a blend.
Marginal rate applied: 37% (default — enter income for your bracket)
Date the property was ready and available to rent. It sets the first-year (mid-month / mid-quarter) depreciation.
Binding-contract date. Under OBBBA, 100% bonus needs the property acquired and placed in service after Jan 19, 2025.
Sets the building life (27.5 yr residential / 39 yr commercial) and the typical reallocation ranges per asset class.
Recovery life: 27.5 years (residential)

Notice. Estimates are based on average engineering-study ranges and IRS MACRS tables (Pub. 946). Actual results depend on a specific cost segregation study, passive activity / real estate professional rules, the OBBBA acquisition date, and your tax situation. Accelerated depreciation is subject to recapture (§1245/§1250) on sale. This is not tax, legal or accounting advice; consult a CPA before acting.
