Unrelated business income (UBI)

Unrelated business income is money a nonprofit earns from a trade or business that isn't substantially related to its exempt mission — and it's taxable, unlike mission income.

Classic examples: a museum running a public parking garage, or a university renting its stadium for concerts. Nonprofits report this income on Form 990-T and pay unrelated business income tax (UBIT) on it.

Modest UBI is normal and legal. What matters for donors is that mission-related activity, not commercial side business, remains the organization's center of gravity.
