Unrelated Business Income Tax for Exempt Organizations
An exempt organization pays tax on income from a trade or business regularly carried on that is not substantially related to its exempt purpose, subject to broad exceptions.
In short
- Unrelated business income tax reaches activity that is a trade or business, regularly carried on, and not substantially related to the exempt purpose.
- All three elements must be present; failing any one of them takes the activity outside the tax entirely.
- Statutory exceptions cover volunteer labor, donated goods, convenience of members, and most passive investment income such as dividends, interest, and many royalties.
- Since 2018 each separate unrelated trade or business is computed on its own, so losses from one no longer offset profits from another.
Sections
An exempt organization still pays federal income tax on some of what it earns. The unrelated business income tax, imposed by 26 U.S.C. 511 and the sections that follow it, applies to income from a trade or business that is regularly carried on and that is not substantially related to the organization's exempt purpose. All three elements must be present. Miss any one and the income is untaxed. A long list of statutory exceptions then removes much of what would otherwise qualify, which is why the tax collects far less than the breadth of the general rule suggests.
Why the tax exists
Congress did not enact this tax to punish commercial activity by charities. It enacted it to remove a competitive advantage. A tax-exempt entity operating a bakery next door to a taxable bakery would win on price for reasons unrelated to efficiency. Taxing the bakery income equalizes the field while leaving exemption for the charitable work intact.
That purpose is the key to reading the statute. When an activity looks like something a commercial business does, and the exempt organization is doing it in the same way for the same customers, the tax is likely to apply. When the activity only makes sense because of the charitable mission, it usually does not.
The three elements
Each element is a separate question, and each has generated its own body of guidance.
- Trade or business. An activity carried on for the production of income from selling goods or performing services. The profit motive matters; a genuinely non-commercial activity is not a business merely because money changes hands.
- Regularly carried on. Judged against how comparable commercial operations run. An annual weekend sale is not regular; the same sale run every weekend of the year is. Frequency and continuity, not total revenue, decide this element.
- Not substantially related. The causal relationship must be to the exempt purpose itself. A museum shop selling reproductions of works in its collection is generally related; the same shop selling unrelated consumer electronics generally is not.
The third element is the one that produces most disputes, and it is often decided item by item rather than for a store or program as a whole. Fragmentation is expressly permitted: a single operation can contain both related and unrelated components, and the unrelated ones are taxed on their own.
The exceptions
The statutory exceptions do a great deal of work. The most frequently used are these.
| Exception | What it covers |
|---|---|
| Volunteer labor | A business in which substantially all the work is performed without compensation. |
| Convenience of members | Activity carried on primarily for the convenience of members, students, patients, officers, or employees of the organization. |
| Donated goods | Selling merchandise substantially all of which was received as gifts or contributions. |
| Passive investment income | Dividends, interest, annuities, and most royalties, subject to the debt-financed property rules. |
| Rents from real property | Generally excluded, but the exclusion narrows when personal property or services are bundled in, or when the property is debt-financed. |
| Qualified sponsorship payments | Acknowledgment of a sponsor's name or logo without qualitative comparison or a call to action. |
Caution: The line between an acknowledgment and an advertisement is thin and consequential. Naming a sponsor and displaying its logo is generally acknowledgment. Comparative claims, price information, or an inducement to buy generally convert the payment into advertising revenue, which is taxable.
Separate computation for each business
Before 2018, an exempt organization aggregated all of its unrelated activities and paid tax on the net. A chronically unprofitable side venture could shelter a profitable one. That changed. Under the rule enacted in 2017 and effective for tax years beginning after 2017, unrelated business taxable income is computed separately for each separate trade or business.
The practical effect is that losses are trapped in the activity that generated them. A net operating loss from one line carries forward against that same line, not against the organization as a whole. Grouping is permitted only within categories identified in the regulations, which draw on industry classification codes, and investment activities are treated under their own rules.
This makes the accounting question — how many separate businesses does the organization have? — a live one, with real dollars attached. Organizations with several revenue-generating programs should settle the grouping before the return is prepared, not while preparing it. The reporting itself runs on the exempt organization return series described on the IRS Form 990 page, with unrelated income reported on a separate business income tax return for exempt organizations.
When tax becomes an exemption problem
Paying the tax is not an admission of anything. An organization can run a taxable unrelated business, report it, pay, and remain fully exempt. The danger arrives when the unrelated business becomes a substantial part of what the organization does, because 26 U.S.C. 501 requires operation exclusively for exempt purposes, read as primarily.
There is no bright-line percentage. Analysis looks at revenue, expenses, staff time, and the attention of management, and it is qualitative as well as quantitative. Organizations approaching that boundary usually respond by moving the activity into a taxable subsidiary, which changes the analysis but introduces its own governance questions — related-party transactions between parent and subsidiary sit squarely inside the concerns discussed in private inurement and excess benefit transactions, and the parent board's oversight duties are the subject of nonprofit board duties and conflict-of-interest policies.
State treatment is separate again. Many states tax unrelated business income by reference to the federal computation, but state conformity dates and modifications vary, and a state may reach income the federal rules exclude. Sales tax exemption for purchases and sales tax collection on sales are two more state questions with no national answer; the general federal overview at the IRS charities pages does not settle them, and state agency directories at USA.gov are the route to the right office.
Questions this raises
Is renting out the building to another group taxable?
Rent from real property is generally excluded, so a plain lease usually is not taxed. Three things break the exclusion: bundling substantial services with the space, such as catering or staffing; renting personal property along with real property beyond an incidental amount; and financing the property with debt, which pulls in the debt-financed property rules and taxes a proportion of the income.
Does a thrift store owned by a charity pay this tax?
Frequently not, because two exceptions often apply at once. If substantially all the merchandise was donated, the donated goods exception removes the income. If substantially all the work is done by unpaid volunteers, the volunteer labor exception removes it independently. A store that buys inventory wholesale and staffs itself with paid employees fits neither exception and is a different case.
Are corporate sponsorships of an event taxable?
A qualified sponsorship payment is excluded. The sponsor may be identified by name, logo, product line, and contact information, and may be thanked publicly. What converts the payment into taxable advertising is promotional content: comparisons with competitors, quality or price claims, or an inducement to purchase. Event programs and signage are where this line is most often crossed without anyone noticing.
Does the tax apply to income earned overseas?
The unrelated business income rules apply to a domestic exempt organization's income wherever earned, not only to United States sources. Foreign taxes paid may be creditable, treaty positions may apply, and separate information reporting obligations attach to foreign subsidiaries and foreign bank accounts. Organizations expanding abroad usually discover the reporting burden is larger than the tax itself.
Working order
Start with an inventory. List every revenue stream, including small ones, and for each ask the three questions in order: is it a trade or business, is it regularly carried on, and is it substantially related. Record the reasoning contemporaneously, because the analysis is fact-specific and memories fade before an examination arrives.
Then apply the exceptions to whatever survives, and document the factual basis for each one claimed — volunteer hours logged, the proportion of donated inventory, the membership status of purchasers. An exception asserted without records is an exception that will not hold.
Finally, settle the grouping for separate computation before year-end, allocate shared expenses on a method the organization can explain, and reconcile the unrelated income reported on the information return with the amounts on the business income return. Mismatches between those two filings are among the easiest discrepancies for a reviewer to spot.
