Frequently asked questions about Mutual Benefit nonprofits
Answers compiled from the IRS Form 990, BMF, Pub 78, and Auto-Revocation List.
- What counts as a Mutual Benefit nonprofit?
- Mutual Benefit nonprofits are US tax-exempt organisations classified under the IRS National Taxonomy of Exempt Entities (NTEE) major group "Y" (Mutual Benefit). The IRS assigns the NTEE code based on the organisation's primary purpose as reported on Form 990.
- How are mutual benefit nonprofits regulated?
- Mutual Benefit nonprofits with annual gross receipts of $50,000 or more must file Form 990 (or 990-EZ) annually with the IRS. Smaller orgs file the 990-N e-Postcard. Failure to file for three consecutive years triggers automatic revocation of tax-exempt status.
- How can I verify a mutual benefit nonprofit's tax-exempt status before granting?
- Cross-reference the organisation against the IRS Auto-Revocation List AND IRS Publication 78. Pub 78 confirms whether donations are tax-deductible; the Auto-Revocation List confirms whether the org has lost its status for non-filing. Givalgo Discover surfaces both signals on every org profile.
- Where can I find Form 990 data for mutual benefit nonprofits?
- Each organisation's Form 990 — including financials, governance, programs, and grants — is publicly available from the IRS. Givalgo Discover aggregates the full corpus (Form 990, 990-EZ, 990-PF, 990-N) and provides a free profile for every IRS-registered mutual benefit nonprofit.
- What's the difference between a 501(c)(3), 501(c)(4), and 501(c)(6)?
- 501(c)(3) is the standard tax-exempt classification for public charities and private foundations; contributions are tax-deductible. 501(c)(4) covers civic-league / social-welfare orgs; contributions are not deductible. 501(c)(6) covers business leagues and chambers of commerce. The IRS subsection code on each Givalgo Discover profile identifies the exact classification.
