Unrelated Business Income Tax for Nonprofits: A How-To Guide

Nonprofits are mission-driven organizations dedicated to serving the public good. However, even mission-focused entities can generate income from activities that aren't directly related to their charitable purpose. When this happens, it's crucial to understand the implications for your organization, particularly regarding the Unrelated Business Income Tax (UBIT). This guide will walk you through identifying, calculating, and managing UBIT so your nonprofit can remain compliant and continue its vital work without unnecessary tax burdens. Our team at Centennial Accounting Group helps many Colorado nonprofits navigate these complexities, ensuring they’re prepared for any tax challenges.

What You'll Need

• A clear understanding of your nonprofit's mission and exempt purpose.
• Detailed financial records for all income-generating activities, including sales, services, sponsorships, and advertising.
• Knowledge of your state's specific tax laws and reporting requirements (if applicable).
• Information on any trade shows, conventions, or membership lists used for fundraising purposes.
• Access to IRS Form 990-T, "Exempt Organization Business Income Tax Return."
• Records of expenses incurred in generating unrelated business income, which can be used for deductions.

Step 1: Understand What Constitutes Unrelated Business Income

The IRS defines Unrelated Business Income (UBI) as income from a trade or business that is regularly carried on and is not substantially related to the organization's exempt purpose. A good rule of thumb is to ask yourself two questions about each income stream:

1. Is this activity a "trade or business"? This generally means any activity that produces income from the sale of goods or performance of services.
2. Is this activity "regularly carried on"? This means the frequency and manner of the activity are consistent with similar non-exempt businesses. For example, a thrift store operated year-round is regularly carried on, while a one-day annual bake sale is generally not.
3. Is this activity "substantially related" to the organization's exempt purpose? If the activity directly furthers your mission, its net income is usually not considered UBI.

Scenario: Imagine a Denver-based animal shelter that operates a small retail shop selling pet supplies. While the shelter's mission is to care for and rehome animals, selling pet supplies is a trade or business. If this shop is open daily and competes with local pet stores, it's likely considered regularly carried on. If the primary purpose of the shop is to generate profit rather than support the animals (e.g., by providing low-cost necessities to adopters), it may be deemed unrelated business income.

Step 2: Identify Potential UBI Sources

Nonprofits can encounter UBI in various forms. Common sources include:

• Operating a retail store or thrift shop that sells general merchandise unrelated to the nonprofit's mission.
• Selling advertising space in publications, on websites, or at events that are not primarily educational or mission-related.
• Providing services to the public for a fee that are not part of your core mission. This could include things like offering parking for a fee at an event, or operating a conference center for external groups.
• Royalties from licensing intellectual property if the income is derived from an activity that constitutes a trade or business and is regularly carried on.
• Operating certain types of fundraising activities like raffles or sweepstakes that are structured as a trade or business, or selling premium merchandise in conjunction with a solicitation.
• Sponsorships where the sponsor receives substantial advertising or other benefits in return.

It's crucial to meticulously track all income streams. Even seemingly small activities can, in aggregate, contribute to UBI. For instance, a Colorado historical society that rents out its preserved venue for weddings and events generates revenue that might be classified as UBI if not carefully managed and structured.

Step 3: Calculate Your Unrelated Business Taxable Income (UBTI)

Once you've identified potential UBI, you need to calculate your net income from these activities. This is your Unrelated Business Taxable Income (UBTI). The calculation is similar to how a for-profit business calculates taxable income:

UBTI = Gross Income from UBI - Allowable Deductions

Gross Income: This is the total revenue generated from the unrelated business activity.

Allowable Deductions: These are expenses directly connected with and allottable to the production of the UBI. Common deductions include:

• Cost of goods sold (COGS) for inventory.
• Salaries and wages paid to employees working on the unrelated activity.
• Operating expenses like rent, utilities, and supplies used for the activity.
• Depreciation on assets used for the unrelated activity.
• Advertising and marketing costs for the unrelated activity.

Important Note: You cannot deduct expenses that are directly related to your exempt function or are for the general support of your organization (like general administrative salaries not tied to the UBI). For example, the Denver Art Museum cannot deduct the cost of displaying its art collection, as this is directly related to its exempt purpose. However, if it operates a separate gift shop selling non-museum-related trinkets, the expenses for that gift shop can be deducted against its profits.

Step 4: Determine Your Tax Liability

If your organization has UBTI of ,000 or more from any single unrelated trade or business, you are generally required to file IRS Form 990-T and pay UBIT. The tax rates for UBIT are the same as those for corporations. For tax year 2026, these rates are:

• 15% on taxable income up to $50,000
• 25% on taxable income between $50,001 and $75,000
• 34% on taxable income between $75,001 and 00,000
• 35% on taxable income between 00,001 and $335,000
• 38.5% on taxable income between $335,001 and 0,000,000
• 35% on taxable income over 0,000,000

Even if your nonprofit is located in Colorado, where specific state UBIT rules may mirror federal guidelines, it's always best to confirm with the Colorado Department of Revenue (CDOR) or a tax professional. Some home-rule cities might also have local tax considerations. Remember to account for the Colorado FAMLI contributions for employees involved in these activities, as those are a business expense. Effective payroll services can help track these contributions accurately.

Step 5: File Form 990-T

If your nonprofit owes UBIT, you must file IRS Form 990-T, "Exempt Organization Business Income Tax Return." This form is used to report your UBI and calculate your tax liability. In addition to the federal filing, check if your state requires a separate UBIT return. Many states follow the federal guidelines, but it's essential to verify.

Form 990-T is typically due by the 15th day of the 5th month after your organization's fiscal year ends. For calendar-year filers, this means May 15th. You may also need to make estimated tax payments throughout the year if you expect to owe at least $500 in UBIT. The IRS requires these payments to be made in four installments, typically due in April, June, September, and January of the following year.

Accurate tax preparation services are invaluable here, ensuring all calculations are correct and deadlines are met to avoid penalties and interest.

Step 6: Consider Strategies to Minimize UBIT

While UBIT is a requirement, there are ways to manage and potentially minimize it:

• Structure your activities carefully: Ensure that any income-generating activities are clearly aligned with your exempt purpose. For example, if you sell educational materials related to your mission, this is less likely to be considered UBI.
• Limit unrelated activities: If an activity is consistently generating a loss or is too complex to manage, consider discontinuing it.
• Leverage the "convenience exception": Some exceptions apply, such as when the goods or services are provided to members, students, or employees for their convenience.
• Seek professional advice early: Consult with accounting professionals who specialize in nonprofit accounting to understand the nuances of UBI and how they apply to your specific situation.

Remember that proper professional bookkeeping is the foundation for any UBIT analysis. Without accurate financial records, it's impossible to correctly identify UBI and calculate tax owed.

Common Pitfalls

Several common mistakes can trip up nonprofits when dealing with UBIT:

• Confusing fundraising with UBI: While some fundraising activities can generate UBI, not all do. Simple donation solicitations or bake sales are typically not considered UBI. However, when fundraising becomes a business operation with significant commercial activity, it can trigger UBIT.
• Overlooking the "regularly carried on" test: A sporadic activity might not be considered regularly carried on, but if it's structured like a business and recurs frequently, it could be.
• Failing to deduct eligible expenses: Nonprofits may miss out on reducing their UBTI by not properly identifying and documenting all allowable deductions related to the unrelated business activity.
• Not filing Form 990-T when required: The threshold for filing is ,000 or more in UBTI. Many organizations miss this deadline, leading to penalties.
• Ignoring state and local UBIT rules: Relying solely on federal guidelines can lead to non-compliance at the state or local level.
