Frequently Asked Questions
What is UBIT (Unrelated Business Income Tax) for nonprofits?
UBIT is the tax imposed on 501(c)(3) and other tax-exempt organizations when they earn income from activities that are (1) a trade or business, (2) regularly carried on, and (3) not substantially related to the organization's exempt purpose. The tax rate is 21% β the same as the corporate rate. Each organization also has a $1,000 specific deduction that reduces UBIT taxable income. UBIT is reported on Form 990-T and must be paid quarterly via estimated taxes if expected to exceed $500.
What income is excluded from UBIT?
Key UBIT exclusions: (1) Dividends, interest, rents from real property, and capital gains β passive investment income is generally exempt from UBIT; (2) Activities conducted with substantially all volunteer labor (more than 85%); (3) Sales of donated merchandise (donated goods thrift shops); (4) Activities carried on primarily for members' convenience (hospital cafeteria, campus bookstore, etc.); (5) Research performed for government; (6) Qualified sponsorship payments that are not advertising. Income from related activities β those that further the exempt purpose β is always exempt.
Is advertising revenue taxable for nonprofits?
Yes, advertising income is one of the most common sources of UBIT for nonprofits. When a nonprofit sells advertising in its publications, website, or events, that advertising revenue is generally subject to UBIT because it is a regular trade or business not substantially related to the exempt purpose. The advertising itself (promoting the advertiser's products/services) does not further the charity's mission. However, "acknowledgments" or "qualified sponsorships" β where the donor simply gets name/logo recognition without promotional language β are NOT considered advertising and are excluded from UBIT.
What is debt-financed income and how is it taxed?
If a nonprofit purchases income-producing property using debt financing, a portion of the income from that property is subject to UBIT β even if the income (like rent) would otherwise be excluded. The taxable portion is calculated by the "acquisition indebtedness to basis" ratio. For example, if a nonprofit buys a rental building with 60% debt financing, 60% of the net rental income is subject to UBIT. As the debt is paid down, the taxable percentage decreases. This rule prevents nonprofits from using tax-exempt status to compete unfairly with taxable businesses in leveraged real estate.
When does a nonprofit need to file Form 990-T?
A 501(c)(3) organization must file Form 990-T if its gross unrelated business income is $1,000 or more in the tax year. This is separate from Form 990 (the informational return). The $1,000 threshold is gross income β before the $1,000 specific deduction. Form 990-T is due by the 15th day of the 5th month after the organization's fiscal year end (May 15 for calendar-year organizations, with a 6-month extension available). Nonprofits with UBIT over $500 must also pay quarterly estimated UBIT.
