Determination Letter
Quick Definition
The official IRS letter confirming that your organization has been granted tax-exempt status — essentially your nonprofit's birth certificate.
What Is Determination Letter?
A determination letter is the document the IRS sends after reviewing and approving your application for tax-exempt status (Form 1023 or 1023-EZ). It's the official confirmation that your organization is recognized as a 501(c)(3) — or whatever section you applied under — and is exempt from federal income tax.
The letter itself is pretty straightforward. It states your organization's legal name, EIN (Employer Identification Number), the section of the tax code you're exempt under, and the effective date of your exemption. It may also indicate whether you're classified as a public charity or a private foundation, which affects your fundraising rules and compliance obligations.
Getting the determination letter is the finish line of the formation process. For a full Form 1023, the wait can be six months to over a year. The streamlined 1023-EZ typically processes in a few weeks to a few months. Once you have it, keep it forever — you'll need to produce it hundreds of times over the life of your organization.
Why It Matters for Nonprofits
Your determination letter is the single most important document your nonprofit owns. You'll need it to open a bank account, apply for grants, register for state tax exemptions, set up donation pages, and prove to major donors that their gifts are tax-deductible. Most foundations won't even look at a grant application without a copy of your determination letter attached.
If you lose your determination letter, you can request a new one from the IRS (using Form 4506-A), but the process takes time. Many organizations keep digital and physical copies in multiple secure locations.
Example
A newly formed environmental education nonprofit files Form 1023-EZ in January. In March, they receive their determination letter confirming 501(c)(3) public charity status, effective retroactive to their formation date. That same week, they use the letter to open a nonprofit bank account, register on GuideStar, set up a Stripe donation page, and submit their first grant application to a local community foundation. Without that letter, none of those steps would have been possible — the foundation requires it, the bank requires it, and Stripe requires it to process tax-deductible donations.
