What Is Form 990-T?

Form 990-T is a tax document used by tax-exempt organizations to report unrelated business income (UBI) and determine any tax liability associated with it. While tax-exempt organizations — such as charities, educational institutions, and religious groups — are generally not subject to income tax, they may still owe taxes on income generated from business activities that are not directly related to their core tax-exempt purpose. This income is subject to the Unrelated Business Income Tax (UBIT), and Form 990-T serves as the primary means of reporting and paying this tax to the Internal Revenue Service (IRS).

Purpose and Scope of Form 990-T

The fundamental purpose of Form 990-T is to ensure that tax-exempt organizations do not gain an unfair advantage over for-profit businesses by engaging in commercial activities unrelated to their tax-exempt mission. Congress established UBIT rules to prevent tax-exempt entities from using their privileged status to compete directly with taxable businesses in areas beyond their charitable or public service objectives.

An organization must file Form 990-T if it generates $1,000 or more in gross income from unrelated business activities during the tax year. The IRS defines unrelated business income as income derived from a trade or business that is regularly carried on and not substantially related to the organization’s tax-exempt purpose. These three criteria — trade or business, regular conduct, and lack of substantial relation — are key in determining whether an activity is subject to UBIT.

Examples of Unrelated Business Income

Unrelated business income can come from a variety of sources, and even a charitable or educational organization may engage in revenue-generating activities that fall outside its primary exempt purpose. Some common examples include:

• Advertising Revenue: A nonprofit that publishes a magazine or maintains a website and sells advertising space may generate unrelated business income.
• Retail Sales: If a university operates a bookstore selling merchandise unrelated to its educational mission, such as clothing or electronics, the income from those sales could be taxable.
• Rental Income from Debt-Financed Property: If an exempt organization rents out real estate that is financed with borrowed money (i.e., debt-financed property), a portion of the rental income may be considered UBI.
• Partnership Investments: If a tax-exempt organization has an interest in a partnership that conducts business activities generating taxable income, it may have to report its share of that income on Form 990-T.

Certain exceptions apply, such as income derived from volunteer-run businesses, royalties, dividends, or passive investment income, but each case must be carefully evaluated under IRS rules.

Filing Requirements and Structure of Form 990-T

Form 990-T is structured similarly to a corporate tax return, with sections for reporting income, deductions, and tax calculations. The organization must first determine its total gross unrelated business income and then subtract allowable deductions to arrive at taxable unrelated business income.

Some key components of the form include:

• Gross Income: Organizations report total revenue from unrelated business activities.
• Deductions: Expenses that are directly connected to earning UBI can be deducted, such as salaries, rent, and supplies. Only expenses that are directly attributable to the unrelated business activities can be deducted.
• Net Operating Losses (NOLs): If an organization incurs a net loss from unrelated business activities, it may be able to carry the loss forward to offset future taxable UBI, subject to IRS limitations.
• Tax Computation: The taxable amount is multiplied by the corporate tax rate to determine the UBIT liability.
• Credits and Payments: Organizations can report estimated tax payments, tax credits, and overpayments from prior years.

If an organization owes $500 or more in UBIT, it must make estimated quarterly tax payments using Form 990-W.

Schedule A and Siloing Rules for Multiple UBI Activities

The Tax Cuts and Jobs Act (TCJA) of 2017 introduced a significant change to the taxation of unrelated business income through the siloing rule (also known as "UBI Basketing"). Under this rule, tax-exempt organizations that engage in multiple unrelated business activities must calculate taxable income separately for each activity rather than aggregating all UBI into a single figure.

To comply with this requirement, organizations use Schedule A of Form 990-T, which provides a breakdown of income and expenses for each separate unrelated business activity. Losses from one unrelated business cannot be used to offset profits from another, ensuring that organizations pay taxes on profitable activities rather than using losses from other ventures to reduce their overall liability.

E-Filing Mandate and Filing Deadlines

Starting with tax years beginning after July 1, 2019, tax-exempt organizations filing Form 990-T are required to file electronically, unless they qualify for a waiver. The deadline for filing Form 990-T depends on the organization’s tax year:

• For calendar year filers, the due date is May 15 of the following year (the same deadline as Form 990).
• For fiscal year filers, the deadline is the 15th day of the fifth month after the close of the fiscal year.

Organizations can request an automatic six-month extension using Form 8868, but any tax owed must still be paid by the original deadline to avoid penalties and interest.

Consequences of Non-Compliance

Failing to file Form 990-T or incorrectly reporting unrelated business income can result in penalties, interest, and potential loss of tax-exempt status in extreme cases. The IRS actively monitors nonprofit activities to ensure compliance with UBIT rules, and organizations found to be engaging in excessive unrelated business activities risk reclassification as taxable entities.

Inaccurate reporting may also lead to an IRS audit, which could result in additional scrutiny of an organization’s financial records. Given the complexity of UBIT regulations, many nonprofits seek professional tax assistance to ensure proper filing and compliance.

The Bottom Line

Form 990-T is a crucial tax document for tax-exempt organizations that generate income from business activities unrelated to their primary mission. It serves as the mechanism for reporting and paying Unrelated Business Income Tax (UBIT) to the IRS, ensuring that tax-exempt entities do not gain an unfair advantage over for-profit businesses in commercial activities. Organizations must carefully evaluate their income sources, maintain separate records for different unrelated business activities, and file on time to avoid penalties.

Proper compliance with Form 990-T helps nonprofits maintain their tax-exempt status while engaging in limited business activities to support their mission. With the IRS’s increasing focus on enforcement, it is essential for organizations to understand the rules surrounding unrelated business income and seek professional guidance when necessary.
