In order to understand the private foundation excise tax, it is important to understand the different types of private foundations. Private foundations can be either non-operating or operating. 

Non-operating foundations are those that do not have any business operations such as those that make grants to charities or provide scholarships. Operating foundations are ones that have business operations such as owning businesses, providing services, or engaging in investments.

In addition to the private foundation excise tax, there are other taxes that may be imposed on private foundations.
