Form 990-T: Managing Unrelated Business Income (UBI) for Nonprofits without Losing Tax-Exempt Status

Nonprofits frequently navigate complex financial landscapes, balancing mission-driven initiatives with operational necessities. One nuanced area that often trips up even experienced founders and finance leaders is unrelated business income (UBI). How you manage this income can influence not just your bottom line but also your nonprofit’s hard-earned tax-exempt status. At the heart of compliance lies Form 990-T, the IRS form for reporting and paying tax on UBI.

This guide offers a founder-friendly roadmap for managing UBI for nonprofits, explaining what it is, how it affects tax-exempt status, and practical strategies to handle it without jeopardizing your organization’s status.

What Is Unrelated Business Income?

Unrelated Business Income (UBI) is income generated from activities that are not substantially related to your nonprofit’s primary exempt purpose, yet they are regularly carried on like a business. For example:

• A charity operating a gift shop selling unrelated merchandise

• A nonprofit running a parking lot open to the general public

• Rental income from debt-financed property (even if related to your organization's mission)

The IRS taxes UBI to prevent nonprofits from gaining unfair competitive advantages over taxable businesses. While your nonprofit enjoys tax-exempt status on mission-related income, UBI is taxable, and if not properly managed and reported, it can jeopardize your exemption.

Understanding Form 990-T: What Nonprofits Need to Know

Form 990-T (“Exempt Organization Business Income Tax Return”) is the IRS form exempt organizations use to report unrelated business taxable income (UBTI) and compute income tax owed on that income.

Who Must File Form 990-T?

Your nonprofit must file this form if it:

• Has gross income of $1,000 or more from unrelated business activities during the tax year

• Recognizes unrelated debt-financed income (income from property financed by borrowed funds)

• Wants to claim specific tax credits related to UBI

Important: Even if the organization owes zero tax because its deductions equal UBI, it generally must still file Form 990-T to report the activity. Not filing can lead to IRS penalties or increased scrutiny, which puts your exemption at risk.

When Is Form 990-T Due?

• Typically due by the 15th day of the 5th month after the close of the tax year (May 15 for calendar-year filers)

• Extensions are possible by filing Form 8868

How Unrelated Business Income Impacts Tax-Exempt Status

UBI itself does not automatically jeopardize your nonprofit’s tax-exempt status. Nonprofits are allowed to generate unrelated business income — the IRS understands organizations must sometimes supplement mission-related revenue.

However:

• Repeated, substantial unrelated business activity can trigger loss of exemption if the IRS determines the business is no longer operated primarily for exempt purposes.

• Failure to file Form 990-T and pay applicable taxes can result in penalties, liens, or even revocation.

• If your nonprofit receives too much income from unrelated sources (depending on the magnitude and pattern), the IRS may reassess your exemption during audits.

Practical Insights

Balance is key. It’s vital to actively monitor the portion of your revenue and activities that fall into the unrelated category to avoid crossing IRS thresholds. Founders should implement accounting tracking systems that clearly separate unrelated business activities from exempt functions. This level of financial clarity both empowers strategic decision-making and satisfies IRS oversight.

How to File Form 990-T: A Step-by-Step Guide

Filing Form 990-T may seem daunting, but taking it step-by-step and enlisting expert bookkeeping support can prevent costly errors.

1. Identify and Segregate UBI in Your Accounting System

• Track income from unrelated activities separately

• Maintain documentation clearly tying income to UBI activities

• Use categories/classes in your bookkeeping software for itemization

2. Calculate Gross Income from Unrelated Business Activities

Sum all income generated regularly from unrelated trades or businesses.

3. Subtract Allowable Deductions Directly Connected to UBI

Deduct expenses that are ordinary, necessary, and directly connected to producing UBI:

• Cost of goods sold

• Employee wages related to the unrelated business

• Rent or utilities for spaces used exclusively in unrelated business

Note: General administrative expenses for the entire organization are typically not deductible.

4. Determine Net Unrelated Business Taxable Income (UBTI)

Gross income minus allowable deductions equals your taxable UBI.

5. Calculate Tax Liability

Corporations generally pay tax at standard corporate rates on UBTI. Trusts and IRAs have a different schedule.

6. Complete and File Form 990-T

• File even if your UBTI results in zero tax (due to deductions)

• Electronically file if required by the IRS; paper filing is still accepted in many cases

• Apply for extension using Form 8868 if necessary

Best Practices to Manage UBI Without Risking Tax-Exempt Status

Monitor UBI thresholds regularly

Set internal reports to review unrelated revenue quarterly or monthly. It’s easier to recalibrate activities early rather than face IRS penalties or audits.

Maintain clear documentation

Detailed records that validate which income streams are UBI and associated expenses will safeguard your filings during any IRS inquiries.

Separate unrelated activities operationally and financially

When feasible, run unrelated business activities in separate entities or divisions to insulate your nonprofit’s exempt functions.
