IRS Schedule A (Form 990): Public Charity Status and Support

IRS Schedule A is the attachment to Form 990 or Form 990-EZ that a Section 501(c)(3) organization uses to prove it qualifies as a public charity rather than a private foundation.1Internal Revenue Service. Schedule A (Form 990) – Public Charity Status and Public Support The schedule identifies which public charity category the organization falls under and, for most filers, runs a five-year math test showing that its funding comes from a broad enough base to justify that status. Nonexempt charitable trusts described in Section 4947(a)(1) must also file it. The completed form becomes part of the public record.

Who Has to Attach Schedule A

Whether you file Schedule A depends on which return you file:

Even a 990-N filer should run the numbers internally if there is any doubt about the support test. The IRS advises that an organization that believes it may have failed the test for two consecutive years should complete Schedule A to check its status, and if the failure is real, begin filing Form 990-PF as a private foundation.3Internal Revenue Service. 990-N Filer Need Not File Schedule A

Schedule A is not a standalone filing. It travels with the 990 or 990-EZ, and a return submitted without it is incomplete.

Part I: Picking Your Public Charity Category

Part I asks the organization to check one box identifying the reason it qualifies as a public charity.1Internal Revenue Service. Schedule A (Form 990) – Public Charity Status and Public Support The twelve options include churches, schools with a regular faculty and enrolled student body, hospitals, and organizations that are publicly supported through contributions or through exempt-function revenue. Your selection should match what appears in the IRS determination letter.

The category you pick controls the rest of the schedule. An organization publicly supported under Section 170(b)(1)(A)(vi) completes Part II. One publicly supported under Section 509(a)(2) completes Part III. A supporting organization completes Part IV. If more than one category could apply, check only one box and explain the alternative basis in Part VI.4Internal Revenue Service. Instructions for Schedule A (Form 990)

The Public Support Tests

The heart of Schedule A is a mathematical showing that funding comes from broad public sources. The IRS measures support over a rolling five-year period, and two different tests apply depending on which type of public charity is filing.5Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Form 990, Schedules A and B: Public Charity Support Test

The 509(a)(1) Test in Part II

Organizations funded mostly by gifts, grants, and government support use Part II. To pass, at least one-third of total support over the five-year measurement period must come from the general public or from governmental units.5Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Form 990, Schedules A and B: Public Charity Support Test Gifts and grants have to be separated from other revenue such as investment income before the percentage is calculated.

The 509(a)(2) Test in Part III

Organizations that earn a significant portion of revenue through activities related to their exempt purpose, such as tuition, admission fees, or service charges, use Part III. This test has two prongs. More than one-third of total support must come from public contributions or exempt-function gross receipts. And no more than one-third can come from investment income and unrelated business income.5Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Form 990, Schedules A and B: Public Charity Support Test Both prongs have to be met over the same five-year window.

Facts and Circumstances Fallback

An organization that fails the automatic one-third threshold on the 509(a)(1) test isn’t automatically out. If its public support percentage exceeds 10 percent, it can still qualify as a public charity by showing through the facts and circumstances of its operations that it is genuinely publicly supported.6Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Form 990, Schedules A and B: Facts and Circumstances Public Support Test The case gets written up in Part VI and typically addresses the breadth of the donor base, the composition of the governing body, and how the organization makes its facilities or services available to the general public. The IRS reviews these under Treasury Regulation Section 1.170A-9(f)(3).

This matters in practice because a single large bequest in one year can pull the ratio below the automatic threshold for an otherwise healthy charity. The facts and circumstances test is built for those years.

Disqualified Persons and the Contribution Cap

The support calculations treat contributions from disqualified persons specially. The rule exists to keep an organization from claiming public charity status when its money really comes from a handful of insiders. Disqualified persons include substantial contributors, foundation managers, and certain family members.7Internal Revenue Service. IRC Section 4946 – Definition of Disqualified Person

A substantial contributor is someone who has given more than $5,000, but only if that amount also exceeds 2 percent of the total contributions the organization has received since inception. Both conditions must be met.7Internal Revenue Service. IRC Section 4946 – Definition of Disqualified Person Family members who trigger disqualified-person status include spouses, ancestors, lineal descendants (including adopted children), and spouses of lineal descendants.

Contributions from these individuals may be capped or excluded from the numerator of the support ratio. Misidentifying disqualified persons is one of the most common Schedule A preparation errors, and it produces an inflated support percentage that the IRS can disallow on examination.

Unusual Grants

A single windfall can distort an otherwise healthy support ratio. The unusual grant rule lets an organization pull certain large, unexpected contributions out of the support test calculation entirely.8Internal Revenue Service. Instructions for Schedule A (Form 990) To qualify, a contribution must:

  • have been attracted by the organization’s publicly supported character,
  • be unusual and unexpected in size relative to normal contribution levels,
  • be large enough that including it would threaten the organization’s ability to pass the one-third or 10-percent test, and
  • come from a party who is not a disqualified person.

Investment income is never an unusual grant. Keep an internal record with the contributor’s name, date, amount, and a brief description, but do not put those details on the return itself. Part VI must show the amount of each unusual grant received each year without naming the donor, because Schedule A is public.8Internal Revenue Service. Instructions for Schedule A (Form 990)

Supporting Organizations in Part IV

Some organizations qualify as public charities not through the support tests but because they exist to support one or more other public charities. These file Part IV, and the IRS recognizes three relationship types.9eCFR. 26 CFR 1.509(a)-4 – Supporting Organizations Type I means the supported organization appoints a majority of the supporting organization’s board. Type II means the same people sit on both boards, so governance is shared. Type III means the supporting organization is operated in connection with the supported organization and must show it is responsive to that organization’s needs and plays a meaningful role in its operations. Type III draws the most IRS scrutiny and comes with its own annual distribution requirements for non-functionally integrated versions.4Internal Revenue Service. Instructions for Schedule A (Form 990)

What Happens if You Fail the Support Test

An organization that falls below the required support threshold for two consecutive five-year testing periods risks reclassification as a private foundation. That has real financial consequences. Private foundations pay a 1.39 percent federal excise tax on their net investment income each year.10Internal Revenue Service. Tax on Net Investment Income They must also distribute at least 5 percent of their noncharitable-use assets annually, and they face stricter rules on self-dealing, lobbying, and excess business holdings. Private foundations file Form 990-PF instead of Form 990, and donor names on that form are not redacted from public disclosure the way they are for public charities.

Filing, Deadlines, and Penalties

Form 990 and its schedules must be filed electronically. The Taxpayer First Act made e-filing mandatory for tax years beginning after July 1, 2019, covering Forms 990, 990-EZ, and 990-PF.11Internal Revenue Service. E-file for Charities and Nonprofits Approved filing software generates Schedule A as an integrated attachment.

The return is due the 15th day of the 5th month after the fiscal year ends. For calendar-year filers that is May 15.12Internal Revenue Service. Exempt Organization Filing Requirements – Form 990 Due Date Form 8868 grants an automatic six-month extension, pushing calendar-year filers to November 15.13Internal Revenue Service. About Form 8868, Application for Extension of Time To File an Exempt Organization Return

Late or incomplete return penalties scale with size. For returns required to be filed in 2026, smaller organizations (gross receipts of $1,309,500 or less) owe $25 per day late, capped at the lesser of $13,000 or 5 percent of gross receipts. Larger organizations (gross receipts above $1,309,500) owe $130 per day, capped at $65,000 per return.14Internal Revenue Service. 2025 Instructions for Form 990 The IRS adjusts these annually from the base statutory amounts in Section 6652.15Office of the Law Revision Counsel. 26 USC 6652 – Failure To File Certain Information Returns, Registration Statements, Etc. A return filed without a required Schedule A is incomplete and can trigger the same penalties.

The most severe consequence is not a fine. An organization that fails to file any required return for three consecutive years automatically loses its tax-exempt status.16Internal Revenue Service. Automatic Revocation of Exemption

Public Inspection

Schedule A is a public document. Federal law requires exempt organizations to make their annual returns and all attached schedules available for public inspection for at least three years from the filing due date or the actual filing date, whichever is later.17Internal Revenue Service. Public Disclosure and Availability of Exempt Organization Returns and Applications – Public Disclosure Overview Refusing to provide copies on request carries a penalty of $25 per day, up to $13,000 per return.18Internal Revenue Service. Public Disclosure and Availability of Exempt Organizations Returns and Applications – Penalties for Noncompliance

Public charities do not have to disclose donor names or addresses. Contributor details go on Schedule B, which is filed with the IRS but redacted before public release.19Internal Revenue Service. Public Disclosure and Availability of Exempt Organizations Returns and Applications – Contributors Identities Not Subject to Disclosure That protection does not extend to anything you write in Part VI of Schedule A. Names entered there become public, which is why the unusual grant rules keep donor identities off the schedule and in your internal records instead.
