Real estate cost segregation is a tax strategy used in the United States that allows property owners to increase cash flow by accelerating depreciation on components of a commercial or income-producing property. By identifying and reclassifying personal property assets, such as lighting, flooring, or HVAC systems, separate from the building itself, owners can claim shorter depreciation lives—typically five, seven, or fifteen years—rather than the standard 27.5 or 39 years. This approach provides significant tax deferral benefits, particularly in the early years of ownership. Cost segregation is commonly applied to newly constructed, purchased, or renovated buildings across various industries. Real estate cost segregation accelerates depreciation deductions by separating property components, reducing tax liability and enhancing cash flow.
