Look Back Study: How to Claim Missed Depreciation on Past Improvements (Form 3115)

 

 

 

Can I claim a missed depreciation on past improvements? Yes, you can often apply Cost Segregation studies retroactively, even for past improvements, by using a “Look Back Study” and filing IRS Form 3115 to adjust your accounting method, which allows you to claim previously missed depreciation in the current tax year without amending prior returns. This is excellent news for catching up on deductions you may have inadvertently left behind.

For large and complex improvements (particularly those exceeding $100,000), an engineering-based analysis review offers far greater precision than standard record review. Such a study helps to accurately identify each component, allocate costs, and confirm if any Partial Asset Dispositions (PAD) are available. By utilizing this strategic retroactive approach, you realign your depreciation with the property's actual condition and ensure that no tax-saving opportunity goes untapped.
