Can a Nonprofit Start a Business?

The Short Answer

A 501(c)(3) organization is allowed to start and operate a business. There is no blanket prohibition in the tax code against a nonprofit selling goods or services, charging fees, or running a commercial-looking operation. What changes is how the income from that business is taxed, and in some cases whether running it is better done directly or through a separate entity.

Related Business Income Is Not a Special Case

If the business activity itself furthers the organization's exempt purpose, rather than just funding it, the income is treated like any other exempt-purpose revenue and is not subject to unrelated business income tax. A nonprofit theater selling tickets, or an educational nonprofit selling the textbooks it publishes, are running businesses that are substantially related to their exempt purposes, so this income stays untaxed.

Unrelated Business Income Is the Activity That Gets Taxed

A business that is not substantially related to the organization's exempt purpose, such as a charity operating an unrelated parking garage or a manufacturing line, produces unrelated business income. Once that income reaches $1,000 or more in gross receipts for the year, the organization must file Form 990-T and pay tax on the net income, calculated largely the way a taxable corporation would, per the IRS. This filing and tax obligation exist alongside, not instead of, the organization's regular annual return.

Operating the Business Directly vs. Through a Subsidiary

A nonprofit can run a business activity directly inside the exempt organization, reporting any unrelated income on Form 990-T as described above. Alternatively, many nonprofits set up a separate, wholly owned for-profit corporation to run the commercial activity. The subsidiary pays its own corporate income tax on its profits like any other business, and dividends it pays up to the parent nonprofit are generally excluded from unrelated business income as passive investment income, per the IRS's rules on exclusions from unrelated business income, as long as the dividend income itself is not debt-financed.

Why Some Nonprofits Choose the Subsidiary Structure

Running a sizable or higher-risk commercial activity through a separate for-profit subsidiary creates a legal and financial boundary between that activity and the nonprofit's exempt operations. It can also make it easier to demonstrate that the commercial activity is not crowding out the organization's exempt purpose, since the business sits in its own entity with its own books, even though it is still owned and controlled by the nonprofit.

What Doesn't Change Either Way

Regardless of which structure you use, the organization still needs to track which of its activities are exempt-purpose-related and which are not, since that distinction drives both the UBIT filing requirement and the bigger-picture question of whether the organization's activities still support its exempt purpose overall. A subsidiary changes who pays the business's own tax; it does not remove the need to track this distinction.

The Real Risk Is Scale, Not the Business Itself

The IRS does not set a precise percentage at which unrelated business activity becomes too large, but a nonprofit whose unrelated commercial activity has grown to dominate its budget, staff time, or public identity risks a finding that it is no longer organized and operated primarily for its exempt purpose. That risk exists whether the activity runs directly inside the nonprofit or through a subsidiary, since the IRS can still look at the overall picture when the subsidiary is closely tied to the exempt parent.

Decide Related vs. Unrelated Before You Launch, Not After

Map out whether a planned business activity is substantially related to your exempt purpose before you start it, since that answer determines your tax treatment from day one and is harder to untangle retroactively once revenue is already coming in.

A Subsidiary Adds Formalities, Not Just Tax Benefits

Setting up a for-profit subsidiary means a second corporation with its own filings, its own registered agent, and its own tax returns, on top of the nonprofit's existing obligations. Weigh that administrative load against the liability and clarity benefits before choosing this structure for a smaller or lower-risk activity.

Keep Governance Separate, Not Just Accounting

If you run a subsidiary, keep its board decisions, contracts, and day-to-day management distinguishable from the nonprofit parent's own governance, rather than treating the subsidiary as an informal department. Blurring that line can undercut the legal and tax separation the subsidiary is meant to provide.

Watch the Trend Line, Not Just One Year's Numbers

A single profitable year from a business activity is not usually a problem. A multi-year trend where unrelated commercial revenue keeps growing as a share of the organization's total activity is the pattern worth reviewing with a tax professional before it becomes an IRS concern.

This Is Not Legal or Tax Advice

Whether a specific business activity is related or unrelated to your exempt purpose, and whether a subsidiary structure makes sense for it, depends on your organization's specific facts. A nonprofit attorney or tax professional can help you structure a new business activity correctly from the start.
