Cost segregation is an IRS-approved tax strategy that reclassifies components of your Missouri real estate such as flooring, lighting, landscaping, and parking lots from standard 27.5- or 39-year depreciation into shorter 5-, 7-, or 15-year schedules. This front-loads deductions, dramatically reducing your federal tax liability in the early years of ownership and freeing up cash flow to reinvest in additional Missouri properties.
