When Must an Exempt Organization File Form 990-T?

Whether an activity produces unrelated business taxable income is a separate question from whether a return is required. Organizations routinely conclude that a silo will break even or run at a loss and then decline to file, which is the wrong test. The filing obligation turns on gross income.

The filing trigger

Under section 6012 and the regulations at § 1.6012-2(e) and § 1.6012-3(a)(5), an organization otherwise exempt under section 501(a) must file Form 990-T for a tax year in which it has gross income from an unrelated trade or business of $1,000 or more. Gross income means gross, before the specific deduction, before deductions directly connected with the activity, and before any net operating loss carryover.

A silo that generates $40,000 of gross receipts and $55,000 of directly connected deductions still requires a return, and filing is how the loss is preserved for the future within that silo.

Who is covered

• Organizations exempt under section 501(a), including 501(c)(3) charities, 501(c)(4), (c)(6), and social clubs under 501(c)(7)
• Section 401(a) qualified plan trusts and section 501(c)(17) trusts
• IRAs, Roth IRAs, SEPs, SIMPLEs, Archer MSAs, HSAs, and Coverdell ESAs with $1,000 or more of gross unrelated business income
• State colleges and universities described in section 511(a)(2)(B)

Common gross-income triggers that get missed

• Debt-financed income under section 514, including income from leveraged real estate and margin accounts
• Schedule K-1 unrelated business taxable income reported by alternative investment partnerships, including from lower-tier entities
• Advertising income in a periodical, which is a separate activity from qualified sponsorship payments
• Rental of real property where substantial personal services are provided, or where personal property rent exceeds the incidental threshold

Due date, extension, and filing method

For most organizations exempt under section 501(a), Form 990-T is due by the 15th day of the 5th month after the end of the tax year. Employees' trusts described in section 401(a), IRAs, and similar accounts file by the 15th day of the 4th month. Form 8868 provides an automatic six-month extension of time to file, and it does not extend time to pay. Form 990-T is subject to the electronic filing requirement.

Estimated tax

An organization expecting $500 or more of unrelated business income tax for the year must pay estimated tax during the year under section 6655. This is the most common source of avoidable penalty on a first-year 990-T, because the liability is often identified only when the K-1 package arrives after year end.

Computing the tax once you are in

Income and deductions are computed separately for each unrelated trade or business under section 512(a)(6) and § 1.512(a)-6, generally identified by two-digit NAICS code, and a loss in one silo does not offset income in another. The $1,000 specific deduction under section 512(b)(12) is applied once at the organization level, not per silo. Corporations are taxed at the 21% rate; trusts use the trust rate schedule.
