A fixed asset review is an engineering-based analysis that examines property components and asset classifications to ensure accurate depreciation schedules and optimal tax treatment. Our reviews identify assets that qualify for accelerated depreciation under IRS guidelines, reclassifying them from standard 27.5 or 39-year schedules into shorter 5, 7, or 15-year timeframes. This process involves detailed property inspection, component identification, cost allocation using engineering methodologies, and comprehensive documentation that supports the classifications. The result is a detailed fixed asset schedule that maximizes your tax deductions while maintaining full IRS compliance and audit defensibility.
