Pre-sale study review Cost Segregation: Study scope
Define what the property engagement includes before work begins. Resolve compare timing benefits with sale plans and implementation costs using property-specific records.
The issue this scenario creates
A short remaining holding period can change the economic value of accelerated depreciation. Ask the preparer to model sale consequences instead of focusing only on first-year deductions.
The main objective is to compare timing benefits with sale plans and implementation costs. A useful analysis makes the ownership and timeline understandable before anyone applies a reclassification estimate. Do not replace missing history with an assumed new purchase or a generic depreciation percentage.
Study scope approach
A scope should identify the property interest, relevant buildings and components, acquisition and improvement periods, available records, and excluded work. It should describe the report and schedules being delivered, who performs the technical work, and how missing information will be handled. A broad promise to maximize deductions does not resolve these operational questions.
Request written confirmation of the scope, fee, deliverables, evidence requirements, and change process. Separate property analysis from return preparation and advisory services. If the facts change during intake, ask whether the engagement needs a revised cost pool or additional work instead of quietly expanding the original scope.
Scenario-specific evidence
Start with current asset schedule, planned sale timeline, expected allocations, and study proposal. Connect each record to the event it establishes. Explain conflicts and missing years rather than presenting a single unexplained number.
| Field | What to record |
|---|---|
| Main question | Compare timing benefits with sale plans and implementation costs |
| Source documents | Current asset schedule, planned sale timeline, expected allocations, and study proposal |
| Known uncertainty | Ignoring recapture and transaction costs in the feasibility discussion |
| Event timeline | Original acquisition or transfer; changes in rental use; additions, removals, and prior filing events. |
| Reconciliation | Supported opening amount, relevant adjustments, land and separate assets, prior treatment, and the cost pool used in the report. |
Hypothetical example
An owner plans to sell a rental within the next year but receives a large reclassification estimate.
The review should guard against ignoring recapture and transaction costs in the feasibility discussion. Resolve that concern using the specific records above. The example illustrates a process question, not an available deduction or an actual completed client study.
Question to resolve before closing this task
Does the written engagement describe the ownership and events above, and does it exclude any work the owner expects?
Write down the response and retain the supporting record. Assign an owner to any remaining issue and confirm whether it changes the study scope, projected benefit, delivery timeline, or implementation cost. A property report and a usable deduction are separate steps in the workflow.
Practical completion checklist
- Identify the actual property owner and reporting taxpayer.
- Preserve original records and explain missing information.
- Keep existing assets separate from later additions and replacements.
- Confirm the provider and return preparer have accepted the same basis reconciliation.
- Retain the final report and the schedules actually implemented.

These references explain the underlying tax framework. The checklists and scenarios on this page are editorial tools for gathering evidence, not quotations or asset-specific rulings from the IRS. The audit guide is examination guidance, not an official pronouncement of law or certification of a provider. A return preparer must apply current authority to the particular property, taxpayer, and filing year.
