A tax-exempt ID is the IRS determination letter recognizing that your organization qualifies for exemption from federal income tax under a specific section of the Internal Revenue Code, most often Section 501(c)(3). To get one, you incorporate your organization under state law, obtain an Employer Identification Number, then apply to the IRS on Form 1023 or the streamlined Form 1023-EZ. If approved, the IRS mails a determination letter tied to your EIN — that letter is what donors, grantmakers, and state tax agencies actually want to see.
Tax-Exempt ID vs. EIN
These get confused constantly, and the distinction matters. An EIN is a nine-digit number the IRS assigns to any business entity so it can be identified for tax reporting. Corporations, partnerships, and nonprofits all have one. Having an EIN says nothing about whether you owe tax.
Tax-exempt status is a separate determination. You obtain the EIN first, then apply to the IRS for recognition of exemption. If the IRS approves the application, it issues a determination letter that references your EIN and states your exempt classification. When someone asks for your “tax-exempt ID,” they usually mean that determination letter combined with your EIN, because together they prove exempt status. The EIN by itself does not.
What Recognition Actually Gives You
Three things, mainly. Organizations recognized under Section 501(c)(3) are exempt from federal income tax on revenue connected to their exempt purpose.1Internal Revenue Service. Publication 557, Tax-Exempt Status for Your Organization Donors can deduct their contributions on their own federal returns.2Internal Revenue Service. Exemption Requirements – 501(c)(3) Organizations And many foundations and government grant programs restrict eligibility to organizations with a current determination letter, so without one you’re locked out of significant funding.
Recognition does not make every dollar tax-free. If your organization earns $1,000 or more in gross income from a business activity not substantially related to your exempt purpose, you owe tax on that income and must file Form 990-T.3Internal Revenue Service. Unrelated Business Income Tax A charity that runs a gift shop selling items unrelated to its mission still owes tax on those sales. And if you have employees, you still owe payroll taxes — exempt status covers income tax, not withholding obligations.4Internal Revenue Service. Exempt Organizations – What Are Employment Taxes
Which Section You Apply Under
Section 501(c)(3) is the best-known category and the only one that lets donors deduct their contributions in full. It covers charitable, religious, educational, and scientific organizations. But the tax code recognizes more than two dozen exempt categories, and the right one depends on what your organization does:5Internal Revenue Service. Other Tax-Exempt Organizations
- 501(c)(4) — civic leagues and social welfare organizations.
- 501(c)(5) — labor, agricultural, and horticultural organizations.
- 501(c)(6) — business leagues, chambers of commerce, and trade associations.
- 501(c)(7) — social and recreation clubs.
- 501(c)(19) — veterans’ organizations.
Classification determines both the application form and the rules you’ll live under. Section 501(c)(3) organizations file Form 1023 or 1023-EZ; most other categories file Form 1024 or 1024-A.6Internal Revenue Service. Exempt Organization Types A 501(c)(4) social welfare group can engage in more political advocacy than a 501(c)(3), but contributions to it are generally not deductible for the donor. Pick the wrong section and you’ll either fail the application or end up under rules that don’t fit your mission.
What to Do Before You Apply
The IRS expects your organization to already exist as a legal entity before it will consider your application. Three things need to happen first.
Incorporate under state law. Most exempt organizations form as nonprofit corporations by filing articles of incorporation with the Secretary of State. Your articles need specific language committing the organization to operating exclusively for exempt purposes and dedicating assets to exempt purposes upon dissolution. The IRS checks for this on the application, and a missing dissolution clause is a common reason applications get held up.
Draft bylaws. Bylaws govern how your board runs — how officers are elected, how meetings work, how decisions get made. Most states don’t require you to file bylaws, but the IRS asks for a copy with the application.
Get an EIN. The IRS requires every organization applying for exempt status to have an EIN, even if you have no employees. You can apply online through the IRS website and receive the number immediately at no cost.7Internal Revenue Service. Application for Recognition of Exemption
Only after these three steps should you move to the federal application.
Filing the Federal Application
For 501(c)(3) status, the IRS offers two paths. Both are filed electronically through Pay.gov, and both require the user fee at submission.8Internal Revenue Service. Instructions for Form 1023
Form 1023, the Full Application
Form 1023 requires a detailed narrative of your past, present, and planned activities, plus financial data — projected budgets for new organizations, actual financials for existing ones. You upload your articles of incorporation, bylaws, and information about your directors and their compensation, all consolidated into a single PDF.9Internal Revenue Service.

Form 1023-EZ, the Streamlined Application
Smaller organizations that meet every item on the IRS eligibility worksheet can use this shorter form. The two thresholds most applicants run into: annual gross receipts cannot have exceeded $50,000 in any of the past three years and cannot be projected to exceed $50,000 in any of the next three, and total assets cannot exceed $250,000.11Internal Revenue Service.

How Long It Takes
The IRS processes applications in the order received. As of early 2026, the IRS issues 80% of Form 1023-EZ determinations within about 22 days and 80% of full Form 1023 determinations within roughly 191 days.12Internal Revenue Service. Where’s My Application for Tax-Exempt Status Applications flagged for additional review take longer — up to 120 days even on the streamlined form.
The IRS will expedite a Form 1023 application if you show compelling cause, such as a pending grant your organization will lose without the determination letter, or disaster relief work that demands immediate operation. The request must be in writing, must explain the urgency, and is granted at the IRS’s discretion. Expedited processing is not available for Form 1023-EZ.13Internal Revenue Service. 14Internal Revenue Service. Federal Tax Obligations of Nonprofit Corporations Most organizations apply separately at the state level, and requirements vary.
Sales tax exemption. Many states issue sales tax exemption certificates to qualifying nonprofits, letting them buy for organizational use without paying state sales tax. The certificate comes from the state tax agency, not the IRS, and you present it to vendors at purchase. Some states accept multi-state certificates; others require their own form. Your federal determination letter is usually a prerequisite.
Charitable solicitation registration. If your organization plans to ask for donations, roughly 40 states require registration before you solicit their residents. Registration typically goes through the state attorney general’s office or secretary of state, with some exemptions for religious institutions and very small charities.15Internal Revenue Service. Charitable Solicitation – Initial State Registration Fundraising in multiple states means registering in each. Fees and renewal cycles differ.
Keeping Your Status Active
The determination letter isn’t permanent on its own. Nearly every exempt organization must file an annual return with the IRS, and which one depends on size:16Internal Revenue Service. Form 990 Series – Which Forms Do Exempt Organizations File
- Form 990-N, the 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, the full return, for gross receipts of $200,000 or more or total assets of $500,000 or more.
Miss three consecutive years and the IRS automatically revokes your exempt status by operation of law under Section 6033(j).17Internal Revenue Service. Automatic Revocation of Exemption The revocation isn’t discretionary and it isn’t quiet — the IRS publishes revoked organizations on a public list. Even the two-minute e-Postcard counts, so the smallest organizations aren’t off the hook. Getting reinstated means re-applying, paying the user fee again, and filing the missing returns, and donors’ contributions during the gap may not be deductible. Filing on time each year is far easier than the alternative.
