Is interest income on a non profit organization taxable?

Interest income earned by a nonprofit organization is generally taxable unless it is related to the organization’s exempt purpose. If the interest income comes from activities unrelated to the nonprofit's mission, it may be subject to unrelated business income tax (UBIT). However, interest from investments that support the nonprofit's exempt activities is usually not taxable. It’s advisable for nonprofits to consult with a tax professional to ensure compliance with IRS regulations.
