Important notes

Cost segregation accelerates depreciation — it does not create new deductions, it moves them earlier. This is a timing benefit, not a permanent tax elimination.
Bonus depreciation is subject to recapture on sale. Consult a tax professional before proceeding.
Results are estimates based on industry-average reclassification percentages. Actual results vary by property and require a formal engineering study.
