Many nonprofit leaders focus heavily on programming and fundraising—but forget one critical compliance requirement: the IRS Public Support Test.
This test isn’t just a formality. It’s how the IRS ensures your organization is truly a public charity—supported by the broader community, not just a handful of donors. Failing it for two consecutive years can lead to your public charity status being revoked—a consequence that could impact your tax-exempt status and donor trust.
📊 What Exactly Is the Public Support Test?
The Public Support Test is a calculation built into Form 990. It measures how much of your revenue comes from public sources (like individual donors, grants, and membership dues) versus private or large contributors.
You must pass the test over a rolling 5-year period, and if you fail it two years in a row, the IRS may reclassify your organization as a private foundation—with much stricter rules and oversight.
🚩 What Impacts Your Public Support Test Results?
Several revenue sources and reporting decisions can make or break your public charity status:
✔️ Government grants & public funding
✔️ Contributions from large donors (subject to thresholds)
✔️ Membership dues and how they’re categorized
✔️ In-kind donations and how they’re reported
✔️ Non-traditional income, like event revenue or unrelated business activities
If you’re not carefully tracking these numbers or reviewing the public support schedule annually, you could be blindsided at tax time.
