Definition
Material participation is the IRS standard for being actively involved enough in an activity that its income or loss is treated as non-passive.
How It Works
The IRS provides several tests, the most common being more than 500 hours in the activity, or more than 100 hours and more than anyone else. Meeting a test makes the activity non-passive, which can free losses to offset other income.
Example
A short-term rental owner who spends more than 100 hours operating the property, and more than anyone else, materially participates and can use the losses against other income.
When It Works Best
It is central to the short-term rental exception and to qualifying as a real estate professional.
Who It Applies To
Owners of rentals and businesses seeking non-passive treatment.
Watch-Outs
Material participation must be genuine and documented with contemporaneous time logs. It is a frequent audit issue.
