IRS Form 990-T (Schedule A) – Unrelated Business Taxable Income From an Unrelated Trade or Business – Tax-exempt organizations like nonprofits, charities, and trusts often generate income from activities outside their mission—think advertising sales, facility rentals, or merchandise vending. While exempt from federal income tax on mission-related revenue, unrelated business taxable income (UBTI) is fair game for the IRS. Enter IRS Form 990-T Schedule A, the mandatory attachment to Form 990-T that breaks down UBTI for each separate unrelated trade or business, ensuring accurate taxation and compliance.
For tax year 2024 (filed in 2025), Schedule A consolidates prior schedules (e.g., for advertising or parking income) into one streamlined form, with new lines for credit adjustments. This SEO-optimized guide covers Form 990-T Schedule A filing requirements, who must file, deadlines, step-by-step instructions, and updates. Nonprofits with $1,000+ in gross UBTI: Don’t risk penalties—e-file by May 15, 2025. Download the 2024 form at IRS.gov/Form990T.

What Is IRS Form 990-T Schedule A?
Schedule A (Form 990-T), “Unrelated Business Taxable Income From an Unrelated Trade or Business,” calculates UBTI separately for each distinct activity under Regulations section 1.512(a)-6. This “silo” approach—mandated since 2020—prevents losses from one business offsetting profits in another, potentially increasing your tax bill.
Key purposes:
- Report Gross Income & Deductions: By NAICS code, for activities like sales, rentals, or investments.
- Compute Net UBTI: Subtract allowable expenses; aggregate positives on Form 990-T, Part I, line 1.
- Handle Specifics: Includes sections for exploited activities, controlled entities, and advertising.
Unlike Form 990-T (the main return for UBIT liability), Schedule A is filed one per unrelated trade or business. For 2024, it integrates all prior sub-schedules, simplifying prep while adding lines for nonrefundable credits.
Who Must File Form 990-T Schedule A in 2025?
Any tax-exempt organization filing Form 990-T for $1,000+ gross UBTI must attach a separate Schedule A for each unrelated trade or business. This includes:
- 501(c)(3) Charities: E.g., museum gift shops or event sponsorships.
- 501(c)(4)–(c)(7) Groups: Social clubs with bar sales.
- Title-Holding Corporations: Under section 501(c)(2).
- Trusts & IRAs: 401(a) trusts, IRAs, Roth IRAs, ESAs, or Archer MSAs with passive income.
- State Colleges/Universities: Dorm rentals or concessions.
Exceptions: No Schedule A if filing only for proxy tax (lobbying) or certain refunds (e.g., RIC/REIT gains). Consolidated filers (e.g., under section 1501) aggregate but still silo by business.
