Mixed-use buildings: Depreciation history request

Recover prior schedules and reporting before changing the property analysis. Map commercial and residential areas and shared systems.

Preparation resource. Record completion does not determine eligibility, deductions or tax savings. Ask your qualified tax professional to resolve the facts and applicable rules.

What this file should establish

Collect filed returns, asset exports, prior reports and later additions. Identify missing records and who has requested them. Do not assume no depreciation was reported merely because the owner cannot find the schedule.

Map commercial and residential areas and shared systems.

A situation to work through

A retail unit and apartments share a major building system.

For this situation, start with floor plan. Identify the period and legal owner before combining it with the other records. Keep the original source and explain any adjustments in a separate reconciliation.

Review point

Record use, ownership and allocation assumptions for the shared work.

A proposed catch-up amount ignores earlier reporting.

Question for the reviewer

What reporting history must be reconstructed before selecting an implementation method?

Expected handoff

A year-by-year history and missing-record log.

Separate facts supported by documents from estimates and unresolved assumptions. Assign each missing item to a responsible person and a date. Send the reconciliation alongside the source references so the reviewer can trace each conclusion.

Your preparation worksheet

Enter a reference to the document, the person who can supply it and the unresolved question. Use file names or locations rather than account numbers or other sensitive information. Entries stay in this page until you close or refresh it. They are not sent to us or saved automatically. Export before leaving.

Mark not applicable only after noting why. A collected record can still require correction. Review the exported file before sharing it with your adviser.

Source and review boundaries

Use the following primary guidance to frame the questions. The worksheet organizes facts; it does not replace analysis of the relevant year, ownership, elections or state treatment. Record the applicable period, confirm the source version and retain the preparer's written conclusions with the supporting documents.
