Paying compensation or reimbursing expenses by a private foundation to a disqualified person is generally an act of self-dealing. The general rule does not apply, however, to the extent the payments, which cannot be excessive, are for personal services that are reasonable and necessary to carry out the foundation*s exempt purposes. Thus, it is not an act of self-dealing for a private foundation to pay reasonable compensation to a foundation manager, who is an investment advisor, for managing the private foundation*s investment portfolio. Also, paying reasonable compensation to trustees of a trust would not constitute self-dealing, because their services are necessary. See Exceptions to Self-Dealing.
