Unrelated Business Income Defined

For most organizations, an activity is an unrelated business (and subject to unrelated business income tax) if it meets three requirements:

1. It is a trade or business,
2. It is regularly carried on, and
3. It is not substantially related to furthering the exempt purpose of the organization.

There are, however, a number of modifications, exclusions, and exceptions to the general definition of unrelated business income.
