Material participation. For purposes of the seven material participation tests listed later, participation generally includes any work you did in connection with an activity if you owned an interest in the activity at the time you did the work. The capacity in which you did the work does not matter. However, work is not treated as participation if it is work that an owner would not customarily do in the same type of activity and one of your main reasons for doing the work was to avoid the disallowance of losses or credits from the activity under the passive activity rules.
