Unrelated Business Taxable Income

Last updated 8 October 2026

Unrelated Business Taxable Income (UBTI) is the income generated by a tax-exempt organisation from a trade or business that is not related to its main exempt purpose. Even though the organisation itself is tax-exempt, UBTI is subject to tax to ensure that tax-exempt entities do not have an unfair advantage over regular businesses.

What it means

Unrelated Business Taxable Income (UBTI) applies to organisations like charities or universities that usually don't pay taxes on their main activities. However, if they operate a business unrelated to their main purpose, the income from this business may be taxed.

This rule helps keep competition fair by ensuring these organisations don't use their tax-exempt status to run businesses that compete with taxable entities. For instance, if a university runs a cafe open to the public, the income from this cafe could be considered UBTI.

It is important for these organisations to track UBTI closely to ensure they comply with tax regulations. Correctly identifying and reporting UBTI helps avoid penalties and ensures transparency in financial practices.

Think of it like a school bake sale. The school's main job is to teach, but if they sell lots of cakes all year round, they might have to pay tax because baking isn't their main purpose.

In practice

Real-world examples

Example 1

A charity focused on wildlife preservation earns $10,000 annually from a gift shop that sells general souvenirs unconnected with wildlife. The shop operates as a regular trade separate from its main charitable activities, so this income is considered UBTI and is taxable. If the shop sold only nature guides and conservation merchandise, it would more likely be related.

Example 2

A non-profit hospital runs a commercial laundry service for local hotels, generating $50,000 in income. Laundering hotel linen is unrelated to providing healthcare services, so the net income may be treated as UBTI and subject to tax. The hospital keeps the laundry accounts separate from its patient care accounts.

Example 3

A church operates a public print shop that takes orders from local businesses and earns $20,000 a year. Because commercial printing is unrelated to its religious activities, the net profit is classified as UBTI, and the church must report it and pay tax. It deducts paper, ink, equipment and wages before arriving at the taxable figure.

Formula

Calculation

Unrelated Business Taxable Income (UBTI) = Gross Income from the Unrelated Business - Directly Connected Deductions (any small allowance permitted by the tax authority is also deducted) Example 1: A tax-exempt organisation earns $75,000 of revenue from an unrelated cafe and has $30,000 of directly connected costs. UBTI = 75,000 - 30,000 = $45,000 Only this net figure is taxed. The remaining mission-related income of the organisation stays exempt. Example 2 (shared costs): The cafe uses part of a building that also houses charitable programmes. Total building costs are $40,000 and the cafe occupies 25% of the usable space. Allocated cost = 40,000 x 25% = $10,000 Revised UBTI = 75,000 - 30,000 - 10,000 = $35,000 Sensible allocation of shared costs reduces UBTI, provided the method is reasonable and documented. Example 3 (tax due): Assuming, for illustration only, a 20% tax rate, tax on the first calculation = 45,000 x 0.20 = $9,000, and on the second = 35,000 x 0.20 = $7,000. Example 4 (activity that makes a loss): If the cafe had revenue of $30,000 and direct costs of $38,000, UBTI would be -$8,000. There is no tax to pay, and the loss would normally be carried against future profits of the same kind. It is also a warning that the cafe may be draining funds that could support the charitable mission.

Case study

Seen in the real world

This is a fictional, illustrative scenario. GreenFuture, an environmental non-profit, primarily focuses on conservation projects. They also operate an organic cafe to generate additional funds. In the year in question, the cafe earned $75,000 of revenue.

Since the cafe's operation isn't directly related to conservation, this income is classified as UBTI. GreenFuture calculated its expenses for running the cafe at $30,000, resulting in a net UBTI of $45,000. GreenFuture's finance team ensures they file the necessary tax forms and pay taxes on this UBTI, maintaining compliance with tax laws and sustaining their non-profit status. On review, the illustrative finance team noticed that it had not allocated a share of the building costs and the cafe manager's supervision time.

After documenting a reasonable allocation of $10,000, UBTI fell to $35,000. They kept a timesheet and a floor plan to support the allocation, so that it could be explained clearly if the tax authority asked. The trustees also asked whether the cafe could be reshaped to serve the mission. By hosting free conservation talks and selling only products tied to sustainable farming, a larger part of the activity might become related, though they sought professional advice before making any claim.

Watch out

Common mistakes
