A 501(c)(3) certificate is not a decorative certificate at all. It’s a plain business letter from the IRS, known as a determination letter, printed in black ink on standard white paper under the “Department of the Treasury / Internal Revenue Service” header. There are no borders, no colored ink, no embossed seals, and no signatures in fancy script. The document looks like ordinary federal correspondence, and that is what it is.
Physical Appearance of the Document
The letter arrives on plain white paper. At the top sits the Treasury and IRS header, usually with an IRS mailing address (often a P.O. Box in Cincinnati, Ohio) printed nearby. Spacing is uniform, margins are wide, and the formatting is clean and business-like. Somewhere on the page you’ll see a letter number, either 947 or 1076, which identifies the type of determination.
The body opens with “Dear Applicant” and states that the IRS has determined the organization is exempt from federal income tax under Internal Revenue Code Section 501(c)(3). It confirms that donors can deduct contributions under IRC Section 170, and that the organization qualifies to receive tax-deductible bequests and gifts under Sections 2055, 2106, and 2522, which cover estate and gift tax deductions. The IRS advises keeping the letter, since it can help resolve questions about exempt status with donors, grantmakers, and financial institutions.
If the determination carries additional conditions or explanations, an addendum may be attached as a second or third page. A contact person and telephone number at the IRS appear for follow-up questions.
Key Data Fields Near the Top
A block of identifying information sits near the top of the letter. These are the fields the reader will look at first:
- Employer Identification Number (EIN) — the organization’s nine-digit federal tax ID, used for IRS filings and interactions with banks and grantmakers.1Internal Revenue Service. Employer Identification Number
- Effective Date of Exemption — the date exempt status began. If Form 1023 was filed within 27 months of formation, this date typically matches the legal formation date; otherwise it’s generally the date the IRS received the application.2Internal Revenue Service. Instructions for Form 1023
- Public Charity Status — a code indicating foundation classification, for example 170(b)(1)(A)(ii) for an educational organization or 509(a)(1) for a publicly supported charity.3Internal Revenue Service. Determine Your Foundation Classification
- Contribution Deductibility — “Yes” or “No” confirming whether donations are tax-deductible.
- Form 990 Required — “Yes” or “No” indicating whether an annual information return must be filed.
- Accounting Period Ending — the fiscal year end date for filing purposes.
Letter 947 or Letter 1076
Two versions exist, and which one an organization receives depends on its foundation classification. Letter 947, titled “501(c)(3) Exemption With Definitive Ruling of Public Charity Status,” goes to public charities, including organizations qualifying under IRC 509(a)(1), 509(a)(2), or 509(a)(3) as supporting organizations.4Internal Revenue Service. Processing Foundation Classification and Miscellaneous Requests Letter 1076, titled “Determination of Exemption Under Section 501(c)(3) as a Private Foundation or Private Operating Foundation,” goes to private foundations.5Internal Revenue Service. Determination Letter Processing of Exempt Organizations
Both letters look similar in formatting and share the same core data fields. The differences are the foundation classification shown on the letter and the specific paragraphs the IRS uses to describe the organization’s obligations. Private operating foundations receive additional language in Letter 1076 describing their particular classification.
How It Differs from a State Exemption Certificate
State-level exemption certificates look nothing like the federal letter. Many states issue certificates with decorative borders, colored ink, watermarks, and embossed seals from the Secretary of State or Department of Revenue. Some print on heavier cardstock, and a few issue wallet-sized cards for claiming sales tax exemptions at retail. Those state certificates cover state taxes such as sales, use, or state income tax, and they are issued through a separate application process. A federal 501(c)(3) determination letter does not by itself exempt an organization from state taxes, so if what you’re holding looks ornate and mentions a state agency, it isn’t the federal document.
The Affirmation Letter Looks Similar
If an organization needs a current confirmation of its exempt standing for a bank, grantmaker, or government agency, the IRS can issue an affirmation letter. It’s also plain IRS correspondence, but shorter and focused on current status rather than the original determination details.6Internal Revenue Service.

Getting a Copy If You’ve Never Seen Yours
Losing the physical letter doesn’t affect exempt status. The status is what matters; the paper is just proof of it. Copies are available a few different ways:
- For letters issued January 1, 2014, or later, download a copy for free through the IRS Tax Exempt Organization Search tool on IRS.gov. The downloaded PDF shows the same plain letter format described above.8Internal Revenue Service. EO Operational Requirements – Obtaining Copies of Exemption Determination Letter From IRS9Internal Revenue Service. Tax Exempt Organization Search
- For letters issued before 2014, submit Form 4506-B by email to request a photocopy. The first 100 pages are free for educational institutions and most nonprofits; additional pages cost $0.20 each.7Internal Revenue Service. Instructions for Form 4506-B
- Form 4506-B can also be used to request an affirmation letter, which works the same way as the original for donors and grantmakers.
Subordinate units under a group exemption should contact their central (parent) organization rather than the IRS. The parent holds the group ruling and can confirm coverage.8Internal Revenue Service.
