A property tax consultant specializing in cost segregation analyzes your real estate assets to identify components that qualify for accelerated depreciation. They conduct detailed engineering-based studies to reclassify building elements from standard 27.5-year or 39-year depreciation schedules into shorter 5-year, 7-year, or 15-year categories. This reclassification significantly increases your immediate tax deductions, improves cash flow, and reduces taxable income—all while maintaining full IRS compliance. The consultant provides comprehensive documentation, coordinates with your CPA for seamless implementation, and defends the study findings in the event of an audit.
