Real Estate Professional Status: How High Earners Use Section 469(c)(7) to Turn Rental Losses Into Tax Savings

A cost segregation study uses engineering-based analysis to move 20–45% of a building's basis from 27.5- or 39-year straight-line into 5, 7, and 15-year MACRS classes. Combined with the 100% bonus depreciation permanently restored by the One Big Beautiful Bill Act for property placed in service after January 19, 2025, real estate investors can convert a routine $91,000 first-year deduction into roughly $766,000 — provided they clear IRC §469 passive activity loss limits via real estate professional status, the short-term rental rule, or passive income offsets.
