In the right circumstances, cost seg can create significant tax deductions, improve cash flow and help you recover capital faster. Cost seg is an engineering-based analysis that breaks a property into its individual components and identifies items that can be depreciated much faster. For investors actively acquiring self-storage, expanding operations or making significant improvements, the return of 100% bonus depreciation can dramatically improve after-tax cash flow. Based on the owner's tax situation, the projected tax savings were approximately $421,200. While larger portfolios can produce bigger deductions, many single-facility owners benefit from cost seg as well.
