What it means
Non-profit organisations, charities and trade associations enjoy tax-exempt status to help them focus on their social, educational or community goals. However, they sometimes run commercial enterprises to raise extra funds.
If that activity is not substantially related to the organisation's main exempt purpose, the government treats the earnings as taxable business income. This matters because it stops tax-exempt entities from gaining an unfair advantage over regular businesses that pay tax on their profits.
If a museum opens a gift shop selling items linked to its exhibits, that is related income. But if the same museum runs a commercial printing shop for outside customers, that activity has nothing to do with art or education, so the earnings are subject to tax.
In practice, organisations must carefully track their income streams and separate exempt activities from taxable ones. Expenses directly connected to the unrelated business can be deducted from those specific earnings, so the tax is only paid on the net profit.
Failing to report and pay this tax can lead to penalties and even the loss of tax-exempt status, making proper accounting essential for non-profit managers. Imagine a church that gets free use of a community hall for Sunday services because it is a non-profit.
If the church opens a paid car wash in the car park during the week, it must pay tax on the car wash earnings because washing cars is not part of holding church services.
In practice
Real-world examples
Example 1
A local animal shelter with tax-exempt status runs a commercial boarding kennel for pets owned by holiday makers. Because this service does not directly rescue animals, the profits are subject to Unrelated Business Income Tax. The shelter keeps separate records of kennel income, wages and supplies so the taxable profit can be worked out accurately.
Example 2
A community health charity runs a catering service from its commercial kitchen, selling meals to local businesses at weekends. Since a regular catering trade is unrelated to public health education, the net income faces standard business tax. The charity allocates a fair share of kitchen costs to the catering activity to reduce the taxable profit.
Example 3
A university alumni association sells advertising space in its quarterly magazine to local insurance brokers. Because selling ad space is a commercial enterprise rather than an educational activity, the net advertising revenue is taxed. Costs such as design and printing are deducted from the advertising income before the tax is calculated.
Think of it
Imagine a church that gets free use of a community hall for Sunday services because it is a non-profit. If that church opens a paid car wash in the parking lot during the week, it must pay tax on the car wash earnings because washing cars is not part of holding church services.
Formula
Calculation
Taxable Unrelated Business Income = Gross Unrelated Business Revenue - Directly Connected Deductions
Tax Due = Taxable Unrelated Business Income x Applicable Tax Rate (set by the tax authority)
Example 1:
A charity earns $20,000 from selling advertising space in its magazine to commercial advertisers, and incurs $5,000 in direct design and printing costs.
Taxable income = 20,000 - 5,000 = $15,000
Example 2 (tax due):
Assuming, for illustration only, a flat tax rate of 20%, Tax Due = 15,000 x 0.20 = $3,000.
The charity keeps 15,000 - 3,000 = $12,000 of the net profit for its mission.
Example 3 (a loss):
If the same activity had revenue of $20,000 and direct costs of $26,000, taxable income would be -$6,000. That loss would normally only be used against other unrelated business profits, not against donations or exempt income.Case study
Seen in the real world
This is a fictional, illustrative scenario. GreenEarth, a registered environmental charity, decided to boost its funding by launching a commercial courier service using electric vans. The courier service was open to the general public and competed directly with local delivery firms. In its first year, GreenEarth generated $100,000 in revenue from the courier service.
Operating expenses, including van leases, fuel and driver wages, totalled $70,000. When preparing the annual accounts, GreenEarth's finance manager consulted the tax rules. Because the delivery service did not advance environmental education or conservation, the net profit of $30,000 was classified as unrelated business income. GreenEarth correctly reported this on its tax return and paid tax at the applicable rate on that $30,000 profit, avoiding costly penalties and keeping the charity in good standing with regulators.
The illustrative trustees also reviewed whether the courier service was worth running. At a 20% rate, the tax would be $6,000, leaving $24,000 for conservation work, still a useful contribution. They decided to continue, but set up a separate cost centre so that any shared overheads were allocated sensibly and the figures could be defended if questioned.
Watch out
Common mistakes
- Assuming that all income earned by a non-profit organisation is automatically tax-exempt.
- Forgetting to deduct allowable expenses directly linked to the unrelated business activity before calculating tax.
- Failing to track staff time and shared overheads properly between exempt programmes and commercial ventures.
Questions
People also ask
What is the minimum income threshold before this tax applies?
Organisations usually only need to file and pay if their gross unrelated business income exceeds a specific low threshold, such as $1,000, but compliance rules should always be checked locally.
Does selling merchandise always trigger this tax?
Not always. If the merchandise relates directly to the charity's mission, like books sold by a historical society about local history, it is exempt. If it is unrelated, like branded clothing sold simply for profit, it may be taxable.
Can losses from an unrelated business offset charitable donations?
No, losses from unrelated business activities generally can only be used to offset profits from other unrelated business activities, not the donations received for the main charity mission.
