Excise Tax (Foundation)
Definition
Private foundations are subject to a specific excise tax regime under Chapter 42 of the Internal Revenue Code. The most significant provisions are §4940 (1.39% tax on net investment income) and §4942 (30% tax on amounts below the required distribution, escalating to 100% if uncorrected). These excise taxes represent a compliance framework designed to ensure that foundations' tax-exempt assets are deployed for charitable purposes rather than accumulated or used to benefit private interests.
In the Context of Endowment Management
The excise tax framework creates tangible costs that investment policy and spending policy decisions should account for. A foundation that systematically underdistributes relative to its §4942 obligation faces compounding tax exposure. Monte Carlo simulation can estimate the probability of excise tax exposure across market scenarios and spending policy choices.
