The direct answer

The commonly cited test requires more than 100 hours and participation at least as much as any other individual. Exactly 100 hours does not meet that test. Other material participation tests may apply, but each has its own requirements. First verify whether the activity falls outside the rental definition.

A practical example

Illustrative example, not a client result: An owner records exactly 100 hours while a manager records 120. The owner has not satisfied the commonly discussed comparison test.

Test the activity before claiming the loss

First classify the activity for passive-loss purposes, then identify the specific qualification or participation test. A short average stay, a professional license and a cost segregation report answer different questions. Maintain reasonable records of actual work and reconcile them with other commitments. Basis, at-risk and excess business loss limits can still matter after passive treatment is resolved.

Put the answer into your own tax file

Start by identifying the taxpayer, the tax year and the actual transaction. Then connect the transaction to the original documents before choosing a return line or moving money between accounts. A payment description can be useful evidence, but it cannot replace the underlying facts.

The records to review for this topic are: Participation records, guest-use periods, property manager duties, other work calendars and prior elections.

For the example above, write down the decision that needs to be made, the missing information and the person responsible for supplying it. Keep the business, payroll, property and personal return teams aligned when more than one set of records is affected.
