What Is a Tax-Exempt ID and How Do You Get One?

A tax-exempt ID is not a separate number the IRS hands out for exemption. It’s the same nine-digit Employer Identification Number (EIN) your organization already uses, once the IRS has formally approved its tax-exempt status under Section 501(c) of the Internal Revenue Code. You get one in two stages: apply for an EIN when you form the organization, then apply separately for exempt recognition. When the IRS issues a determination letter approving that second application, your EIN functions as your tax-exempt ID on returns, donation receipts, grant applications, and vendor paperwork for the life of the entity.1Internal Revenue Service. Employer Identification Numbers for Tax-Exempt Organizations

Step One: Get the EIN

Every tax-exempt organization needs an EIN. You apply using Form SS-4, online, by fax, or by mail, at no cost.2Internal Revenue Service. About Form SS-4, Application for Employer Identification Number (EIN) Most founders do this early because banks require an EIN to open an organizational account, and states typically want it on incorporation filings.

An EIN by itself doesn’t make you tax-exempt. It’s just an identifier. Exempt status comes only after the IRS reviews a separate application and issues a determination letter.3Internal Revenue Service. Exempt Organizations Rulings and Determinations Letters Your organization should have only one EIN and use it consistently from year to year.

Step Two: Form the Organization and Draft the Right Documents

Before the IRS will consider your exemption, the organization has to exist under state law. That usually means filing articles of incorporation or a similar organizing document. State law sets most of the rules, but the IRS overlays its own content requirements.4Internal Revenue Service. Exempt Organizations – Organizing Documents

For 501(c)(3) status, two clauses must appear in the organizing document:

Missing the dissolution clause is one of the most common reasons applications stall. Put it in the articles at the start rather than amending later. You’ll also need bylaws that establish the governance structure, because the exemption application references them directly.

Step Three: Pick the Right Category and Application Form

Section 501(c) lists more than two dozen categories of exempt organizations.6Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc. Two matter for most new organizations:

  • 501(c)(3) covers charitable, religious, educational, scientific, and literary purposes. It’s the only exempt category whose donors can claim a federal income tax deduction for their contributions. No part of earnings can benefit any private individual, campaigning for or against candidates is banned outright, and lobbying is limited.7Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
  • 501(c)(4) covers social welfare organizations. These can lobby as their primary activity without losing exempt status, but contributions to them are generally not tax-deductible for donors.8Internal Revenue Service. Social Welfare Organizations9Internal Revenue Service. IRC 501(c)(4) Organizations

Within 501(c)(3), every organization is classified as either a public charity or a private foundation. Private foundations face stricter operating rules and excise taxes. Under the code, a 501(c)(3) is presumed to be a private foundation unless it requests and qualifies for public charity status.10Internal Revenue Service. EO Operational Requirements – Private Foundations and Public Charities If you plan to fundraise from the general public, you almost certainly want public charity classification, and your application has to demonstrate broad public support.

Form 1023-EZ vs. Form 1023

The IRS offers two paths to 501(c)(3) recognition:

  • Form 1023-EZ is the streamlined application. You can use it only if your annual gross receipts have not exceeded and are not projected to exceed $50,000 in any of the next three years, and your total assets do not exceed $250,000. The user fee is $275.11Internal Revenue Service. Instructions for Form 1023-EZ12Internal Revenue Service. Frequently Asked Questions About Form 1023
  • Form 1023 is the full application, required for anything above those thresholds. It asks for detailed financial projections and narrative descriptions of planned activities. The user fee is $600.12Internal Revenue Service. Frequently Asked Questions About Form 1023

Both are filed electronically through Pay.gov, with the user fee and copies of your organizing documents.13Internal Revenue Service. Instructions for Form 1023

The 27-Month Deadline

File your exemption application within 27 months from the end of the month your organization was formed and the IRS can recognize your exempt status retroactively to the date of formation.14Internal Revenue Service. Form 1023 – Purpose of Questions About Organization Applying More Than 27 Months After Date of Formation Miss that window and exempt status generally begins only on the date you filed. Donations received during the gap may not qualify as tax-deductible for the people who made them.

How Long It Takes

As of early 2026, the IRS issues 80% of Form 1023-EZ determinations within 22 days. The full Form 1023 takes considerably longer: 80% of determinations issued within 191 days. Applications flagged for further review can add up to 120 days.15Internal Revenue Service. Where’s My Application for Tax-Exempt Status Plan for a potential six-month wait on the full form.

Organizations That Don’t Have to Apply

Churches, synagogues, temples, mosques, and their integrated auxiliaries are automatically considered tax-exempt and are not required to file Form 1023.16Internal Revenue Service. Organizations Not Required to File Form 1023 Many still apply anyway, because a determination letter simplifies dealings with banks, grantmakers, and state agencies that want documentation.

National organizations with local chapters can use a different shortcut. A central organization with at least five subordinates sharing the same exempt purpose can obtain a single group exemption letter covering all of them, so each chapter doesn’t have to file its own application. The central organization must show every subordinate is affiliated with it and under its general supervision or control.17Internal Revenue Service. Group Exemptions and Group Returns

Keeping Your Tax-Exempt ID Valid

The determination letter is not the end. Your EIN stays a valid tax-exempt ID only as long as you meet ongoing filing rules and continue operating for your stated purpose.

Annual Form 990 Filing

Almost every exempt organization must file an annual return from the Form 990 series. Which one depends on size:18Internal Revenue Service. Form 990 Series – Which Forms Do Exempt Organizations File

  • Form 990-N (e-Postcard) for organizations with gross receipts normally $50,000 or less.
  • Form 990-EZ for gross receipts under $200,000 and total assets under $500,000.
  • Form 990 for everything above those thresholds.

Automatic Revocation

This is where organizations lose their status without realizing it. Miss the required annual return or notice for three consecutive years and exempt status is automatically revoked. No hearing. No warning letter that stops the clock.19Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations The IRS does send a notice after two missed filings, but small organizations often overlook it. Once revoked, the EIN is no longer a valid tax-exempt ID, donations stop being deductible, and the organization itself may owe income tax.

Reinstatement means filing a new exemption application and paying the user fee again, even if you were originally exempt from applying. In most cases the reinstated status starts on the new application date, not retroactively. The IRS can grant retroactive reinstatement if the organization shows reasonable cause for the missed filings.20Internal Revenue Service. Reinstatement of Tax-Exempt Status After Automatic Revocation

What Federal Approval Doesn’t Cover

A federal determination letter is not a universal exemption. Two state-level requirements catch many new nonprofits by surprise.

State sales tax. A 501(c)(3) determination letter does not exempt you from paying state sales tax. Most states require a separate application for a state-issued sales tax exemption certificate, usually with your federal determination letter attached. Until that certificate is in hand, the organization pays sales tax like any other buyer.

Charitable solicitation registration. Roughly 40 states require charities to register with a state agency before soliciting donations from residents.21Internal Revenue Service. Charitable Solicitation – Initial State Registration Exemptions vary by state. If you fundraise online and accept donations from across the country, you may need to register in every state where you solicit. Failure to register can bring fines and, in some states, an order to stop fundraising until you comply.

Verifying a Tax-Exempt ID

Donors, grantmakers, and the organizations themselves can confirm exempt status through the IRS Tax Exempt Organization Search tool. Search by EIN or organization name to see whether the organization is eligible to receive deductible contributions, whether it appears on the auto-revocation list, and its recent Form 990 filings.22Internal Revenue Service. Tax Exempt Organization Search Before writing a large check or accepting a grant that requires proof of status, a one-minute check confirms the EIN is still a valid tax-exempt ID.
