Form 990-T

Form 990-T is a tax form used by tax-exempt organizations, including charities and non-profits, to report income from activities unrelated to their main purpose. This form ensures that these organizations pay taxes on such unrelated business income, similar to how businesses pay taxes on their profits.

What it means

Form 990-T is important because even tax-exempt organizations can earn income that does not align with their core mission. This income is called 'unrelated business income' (UBI).

For example, if a charity runs a gift shop, the profits from the shop might be considered UBI. Filing Form 990-T helps ensure that all UBI is reported to the IRS.

Organizations must file this form if their UBI exceeds £750. If not reported, organizations could face penalties or lose their tax-exempt status.

This form outlines the amount of UBI and calculates the tax due. It's essential for maintaining transparency and compliance with tax laws.

Form 990-T also provides the IRS with data to assess the tax-exempt status of the organization.

In practice

Real-world examples.

1

Example

A local animal shelter, a tax-exempt entity, sells merchandise online and earns £5,000 from it. Since this income is unrelated to its primary mission, the shelter files Form 990-T to report and pay taxes on this income.

2

Example

A church rents out its parking lot on weekdays to a nearby business and earns £3,000 annually. This income doesn't relate to the church's religious activities, so it files Form 990-T to report this unrelated business income.

3

Example

A non-profit educational foundation runs a coffee shop inside its premises. The shop generates £10,000 in profits, which are unrelated to its educational mission, requiring the foundation to file Form 990-T.

Think of it

Think of Form 990-T as a way for charities to pay their fair share of taxes on side jobs that don't fit their main work, much like how a person might pay taxes on freelance work on top of their regular job.

Case study

Seen in the real world.

GreenLeaf, a non-profit focused on environmental education, operates a café open to the public. In one year, the café earns £12,000. Since this income isn't part of GreenLeaf's primary purpose, they need to report it using Form 990-T. The accountant calculates the unrelated business income tax liability based on current rates and submits the form. This ensures GreenLeaf complies with tax laws while maintaining its tax-exempt status. By filing Form 990-T, GreenLeaf transparently reports its income, ensuring it meets legal obligations and avoids potential penalties.

Watch out

Common mistakes.

  • Failing to file Form 990-T when unrelated business income exceeds £750.
  • Confusing unrelated business income with donations or grants.
  • Assuming all income is exempt from taxes because the organization is tax-exempt.
