The Cost Segregation Handoff to Your Tax Preparer

The end of a cost segregation study is the beginning of a tax reporting handoff. Give the preparer a complete package and enough time to review how the study fits the property existing depreciation history.

Provide the complete report

Send the final study, classifications, basis reconciliation, assumptions, and any supporting project records. Use a consistent property identifier. A summary showing only total accelerated depreciation is not a substitute for the report and schedules.

Reconcile prior reporting

Include every relevant depreciation schedule and identify any assets already reported separately. Explain acquisitions, improvements, and dispositions. The preparer should reconcile the new classifications with existing schedules before entering the result.

Resolve procedural questions

Ask the preparer how the study will be implemented for the reporting history. Previously depreciated property may raise correction or accounting method questions. Do not assume that every study belongs on an amended return or that the owner should simply overwrite the old schedule.

Review the investor outcome

Separate the deduction calculation from how much can be used this year. Discuss applicable limitations, carryforwards, state treatment, and potential future sale consequences. Keep the implementation record for the next preparer and next tax year.

Action checklist

Who decides how the study is reported on a return?

The tax preparer should evaluate the final report alongside the taxpayer facts, prior reporting, and applicable procedures.
