Unrelated Business Taxable Income (UBTI) is income earned by a tax-exempt entity from activities unrelated to its exempt purpose. Even though endowments, foundations, and pension funds are generally tax-exempt, they owe tax on UBTI.
The Short Answer
UBTI creates tax liability for entities that are otherwise tax-exempt. In private funds, it most commonly arises from debt-financed income when the fund uses leverage. Tax-exempt LPs care because it turns a tax-free investment into a partially taxable one, requires filing Form 990-T, and can trigger state tax obligations.
Common Sources in Fund Structures
- Debt-financed income: Income from investments made with borrowed funds (the most common source).
- Operating business income: Income from an active trade or business conducted by a portfolio company.
- Certain partnership allocations: Pass-through income from fund investments that constitute a trade or business.
Why Tax-Exempt LPs Care
- UBTI exceeding $1,000 requires filing Form 990-T.
- Creates federal and potentially state tax liability for otherwise exempt entities.
- Significant UBTI exposure may lead to requiring a blocker corporation.
- Some tax-exempt investors will decline investments with material UBTI exposure.
- Blocker corporations add cost but eliminate the UBTI problem for the exempt investor.
