Cost segregation offers residential real estate investors an excellent opportunity to accelerate depreciation and reduce tax burdens. However, mistakes in how studies are conducted or integrated with your tax strategy can diminish the benefits or cause compliance issues. At Ash Circle Associates, we guide clients around common pitfalls to ensure you get the maximum advantage safely and efficiently. Here are some key cost segregation mistakes to avoid.
Mistake 1: Choosing a Low-Cost, Inexperienced Provider
Cost segregation is a specialized engineering and tax analysis—cutting corners risks an incomplete or inaccurate study. Low-cost providers may miss assets or misclassify components, exposing you to IRS audits or disallowed deductions. Partnering with knowledgeable experts like Ash Circle Associates ensures your study is thorough, defensible, and optimized.
Mistake 2: Failing to Coordinate with Your Tax Advisor Early
The cost segregation study impacts your tax return significantly. Without early and close coordination with your tax accountant, you may miss vital opportunities or filing requirements. Ensure your cost segregation provider and tax advisor communicate from the start.
Mistake 3: Neglecting to Document Renovations and Improvements
Many investors overlook detailed records of remodeling expenses or improvements, which reduces the value identified in the cost segregation study. Keeping thorough invoices and project documentation is critical to maximizing depreciation deductions.
Mistake 4: Waiting Too Long to Perform a Cost Segregation Study
Delays in conducting a study can mean missing potential tax benefits. While you can perform “catch-up” studies on properties purchased years ago, earlier action provides greater accelerated deductions and cash flow improvements.
Mistake 5: Ignoring Depreciation Recapture Planning
Accelerated depreciation increases taxable gains on eventual property sale due to depreciation recapture. Ignoring this can cause unwelcome tax surprises. Proactive planning with your tax advisors and cost segregation experts mitigates recapture impact.
