Benjamin Franklin is attributed with having once said: “Nothing is certain but death and taxes.” While true, 501(c)(3) organizations, which are exempt from income taxes on activities related to their exempt purposes, could have a different spin on Ben Franklin’s classic line: “Nothing is certain but death, taxes, and Schedule A.” This is because any 501(c)(3) organization (or organization treated as such) claiming tax exemption as a public charity is required in one way, shape, or form to complete Schedule A.
While at first glance the schedule seems easy enough, it is chock-full of nuances, potential limitations, and issues that can make or break a public charity’s tax-exempt status. To borrow from a somewhat less historical source, Avril Lavigne once observed, “Why’d you have to go and make things so complicated?”
This article is the first in a two-part series that provides a detailed examination of Form 990, Schedule A, offering practical guidance to the many organizations responsible for its complete and accurate preparation. Part one will focus on organizations that qualify under Part I, Line 7—509(a)(1) and the steps required to substantiate this classification through the Part II public support test.
What is Schedule A?
As noted above, Schedule A is required for all 501(c)(3) organizations claiming public charity status. Other tax-exempt organizations—such as 501(c)(2)s, 501(c)(4)s, 501(c)(5)s, and 501(c)(6)s—are not required to complete it. Additionally, 501(c)(3) private foundations are exempt from this requirement, as they file Form 990-PF instead.
In simple terms, Schedule A lets the IRS confirm that an organization is truly supported by the public, which is what allows it to keep its public charity status.
This determination begins in Schedule A, Part I, where an organization selects one of the IRS‑defined public charity categories listed on lines 1–12. Certain organizations, such as churches, schools, and hospitals, qualify automatically and are recognized as public charities without needing to demonstrate public support.
For organizations that do not meet one of these automatic classifications, public charity status must instead be demonstrated through one of two IRS public support tests:
- Organizations primarily supported by contributions generally rely on the Part II public support test
- Organizations that earn most of their revenue from program service activities may qualify under the Part III public support test
These two tests form the core framework through which many nonprofits establish and maintain public charity status. However, if an organization fails the applicable public support test for two consecutive years, it will automatically become a private foundation and face stricter rules and reporting requirements. Understanding these basics helps ensure your organization remains well‑positioned to maintain its public charity status and avoid surprises down the line.
The basics: Understanding Schedule A, Part II
Who qualifies?
An organization qualifies as a public charity under Part II, over the five-year computation period, if it meets either of the following thresholds:
- More than 33.33% of its total support is from governmental units, contributions from the general public, and contributions or grants from other public charities
- More than 10% of its total support is from governmental units, contributions from the general public, and contributions or grants from other public charities, and the facts and circumstances indicate it is a publicly supported organization
How is Part II different from Part III?
1. Excess contributions
A critical feature of the Part II public support test is how the IRS treats large contributions from a single donor. On Line 5, organizations must exclude the portion of a donor’s contributions that exceeds 2% of the organization’s total support over the five‑year computation period (the current year plus the four preceding years).
This safeguard prevents an organization from appearing “publicly supported” merely because a few large donors provided most of its support. Instead, the Part II test is designed for organizations that maintain a diverse donor base, with many contributors giving smaller amounts rather than relying on a handful of major donors.
It is important to recognize that certain types of support, such as contributions from governmental units or other publicly supported organizations qualifying under section 170(b)(1)(A)(vi), are not subject to exclusion under the 2% limitation rule. These sources are considered inherently public in nature and therefore always count fully toward public support, even when the amounts received are large.
Example: Calculating excess contributions
Assume the organization has $4,000,000 in total support for the five‑year period.
- The 2% limit is: $4,000,000 × 2% = $80,000
Now consider two donors:
- Donor A contributes $50,000 → below the $80,000 limit
- None of Donor A’s contribution is an excess contribution.
- Full $50,000 counts as public support.
- Donor B contributes $200,000 → above the limit
- Excess: $200,000 − $80,000 = $120,000
- Only $80,000 counts toward public support.
- The $120,000 excess must be reported on Line 5 and excluded from the numerator.
Although large donations are beneficial for operations, they can hurt public support percentages if they are concentrated in a few donors.
Key takeaway: For organizations completing the Part II test, it is essential to stay vigilant around donor concentration throughout the five-year period to ensure that the organization is not receiving the majority of their support from just a few donors.
2. Treatment of unusual grants
Another nuance to the Schedule A, Part II test is the treatment of unusual grants. Unusual grants are large, unexpected contributions from disinterested parties that would skew an organization’s public support percentage if treated as regular support. Because these gifts are extraordinary in size and could jeopardize an organization’s ability to meet the 33.33% public support test or the 10% facts‑and‑circumstances test, they are excluded entirely from both the numerator and denominator of the Part II calculation. This allows organizations to accept significant one‑time gifts without risking “tipping” into private‑foundation status. Organizations must report the amount only in Schedule A, Part VI, and keep internal records documenting the donor, date, and why the grant qualifies as unusual.
3. The 10% facts‑and‑circumstances test
For organizations completing Schedule A, Part II, the 10% facts‑and‑circumstances test provides a backup option for demonstrating public charity status if they fall short of the standard public support requirement. If an organization does not meet the 33.33% public support requirement under Part II, it may still qualify as a public charity as long as it still receives at least 10% public support and it can demonstrate that it truly operates for the benefit of the community.
The IRS considers a variety of factors to determine whether an organization still functions as a public charity. This includes whether it actively fundraises from the general public, whether its board of directors reflects the community it serves, and whether its programs, services, and facilities are open and easily accessible to the general public. The IRS also looks at whether the organization receives grants or support from government agencies, which reinforces that it operates for the general public and not private benefit.
This backup rule helps organizations maintain public charity status during years when donation patterns fluctuate—for example, when a large gift temporarily skews the support ratio or when a newer organization is still building its donor base. With good records and a clear explanation of how it serves the public, many organizations can rely on this test when their support dips below the standard threshold.
4. The Schedule B “special rule”
Organizations that complete and pass the Schedule A, Part II support test may also qualify for the “special rule” related to donor disclosure on Form 990, Schedule B. Under the general Schedule B rules, organizations must report any donor who contributed $5,000 or more during the year, including the donor’s name and address. However, organizations that complete and pass the Part II support test are only required to disclose donors whose contributions exceed 2% of the organization’s total contribution income for the year. This higher disclosure threshold can significantly reduce the Schedule B reporting burden, particularly for organizations that receive a substantial portion of their revenue from individual contributions.
Pro tip: Certain organizations (namely, colleges and universities) can opt to complete the Schedule A, Part II support test in order to take advantage of this special rule as well. For additional information, please see the article, Easy ‘A’ for schools: Pass the test to reduce requirements under Schedule B.
Now that we’ve covered how Schedule A, Part II measures public support based largely on contributions, the next step is understanding the alternative approach. In the second article in our series, we’ll explore Schedule A, Part III, which is often a better match for organizations supported primarily through program services and fees.
