The decision this guide resolves

Count genuine operating participation and substantiate who did the work. Investor-only activities and artificial duplicate entries are not a reliable basis for participation.

A practical fact pattern

Two spouses perform guest messaging while a cleaner handles turnovers. The file must distinguish actual work, shared tasks and the contractor’s participation.

Records to gather before deciding

  • Calendars, work orders and contemporaneous task details
  • Spouse task records
  • Vendor invoices plus available time information

Frequently Asked Questions

Can my spouse’s STR hours count?

A spouse’s participation generally counts for material participation even if the spouse owns no interest and even if the couple does not file jointly. This does not allow the spouses to combine hours to make one spouse a real estate professional; that qualification has a separate individual test.

Do property research and investment seminars count?

Investor-type work, such as reviewing financial statements or studying investments, generally does not count unless directly involved in day-to-day management or operations under the applicable rules. Identify the actual task rather than relabeling research as management. Acquisition and pre-opening work need separate review.

Do cleaner hours count against my 100-hour test?

They can matter when evaluating whether any other individual participated more than you. The comparison is with individuals, not simply the cleaning company’s aggregate bill. Collect reasonable support for who performed the work and avoid assuming every contractor hour is either irrelevant or automatically pooled.

Can I materially participate with a property manager?

A manager does not automatically prevent every material participation test, but outsourced work affects the facts and can defeat the more-than-100-hour comparison. Evaluate another applicable test if supported, the manager’s actual duties and any restrictions on management activities under the facts-and-circumstances test.

Is a year-end reconstructed time log sufficient?

Reasonable evidence can establish participation, but vague estimates and invented hours are weak support. Reconstruct from dated bookings, messages, invoices and calendars, showing actual tasks and duration. Do not create false records or count simultaneous work twice simply to reach a threshold.

How to turn the answers into a return decision

Write down the property owner, affected tax year, the factual test being used and the evidence supporting it. Reconcile the amount on the study or workpaper with the return schedule, identify any limitation and assign the filing task to a named preparer. If a fact is missing, resolve it before treating the estimated deduction as usable.

Reviewed November 8, 2026 by AE Tax Advisors. This is a federal planning resource; the facts, tax year, elections and state rules control the actual return. IRS publications explain rules but do not replace applicable law. The cost segregation audit guide is nonbinding examiner guidance and predates later bonus-depreciation changes.

Bring the facts to a scoped review

A study estimates asset classifications; a tax review determines eligible and currently usable deductions. Ask who reconciles basis, prepares any Form 3115 or amended return, and implements the final schedules. No tax saving or investment outcome is guaranteed.
