Getting an EIN for Your Arizona Nonprofit

The IRS assigns each business a nine-digit federal tax ID called an Employer Identification Number. Think of it as a Social Security number for your organization — the unique identifier the federal government, banks, and grant-makers use to recognize your nonprofit.

Every nonprofit corporation needs an EIN, and it needs one even though it hopes to be tax-exempt. Exempt status doesn't eliminate the need for an identifier; it just changes how the organization is taxed. The EIN is what the IRS uses to track your exemption application, your annual Form 990 filings, and any payroll if you have employees.

Why you can't use a personal SSN

A nonprofit is a separate legal entity with no owners. Using a director's or founder's Social Security number in its place blurs the line between the individual and the organization — exactly the separation that incorporating was meant to establish. Banks won't open a nonprofit account on a personal SSN, the IRS expects the organization to have its own EIN on the exemption application, and grant-makers identify you by EIN. Get the organization its own number.

Timing matters. The EIN sits in a specific spot in the formation sequence.

The right moment

Get your EIN after the Arizona Corporation Commission approves your Articles of Incorporation and before you open a bank account or apply for 501(c)(3) status. You want the corporation to legally exist first — the EIN application asks for the legal name and formation details of an actual entity. Once the Articles are approved and you have your board organized, apply for the EIN. It's free and instant, so there's no reason to delay once the corporation exists.

What the EIN unlocks

• Bank account. Banks require the EIN (and usually the filed Articles and an organizing resolution) to open a nonprofit account.
• Exemption application. Form 1023 and 1023-EZ both ask for the organization's EIN. You can't apply for exemption without one.
• Payroll. If you hire staff, the EIN is your employer identifier for payroll taxes.
• Grants and donations. Grant applications and donation platforms identify your nonprofit by EIN.

The IRS issues EINs at no cost. The fastest route is the online application, and for most nonprofits it takes only a few minutes.

Applying online

Use the IRS EIN Assistant at IRS.gov. The online application is available during the IRS's posted hours and must be completed in one session — you can't save and return. When you finish, the EIN is issued immediately, and you can download and print the confirmation notice (the CP 575) to use right away.

Information you'll need

• The nonprofit's exact legal name as it appears on the approved Articles
• The Arizona address of the organization (its known place of business)
• The name and Social Security number or ITIN of the "responsible party" — typically a principal officer or director
• The type of entity (you'll indicate it's a nonprofit/other) and the reason for applying

The responsible party

The IRS requires a "responsible party" — a real individual, usually a director or officer, who controls or manages the organization. This person provides their SSN or ITIN to identify themselves on the application. It doesn't make them personally liable for the nonprofit's obligations; it's just the IRS's way of tying the application to an accountable human.

If you can't apply online

Applicants whose responsible party lacks an SSN or ITIN, or who otherwise can't use the online tool, apply using Form SS-4 by fax or mail. This is slower — allow additional time — but it's the alternative when the online path isn't available.

A few missteps trip up nonprofit founders at this stage. Knowing them in advance saves headaches.

Applying before the corporation exists

Don't apply for the EIN before your Articles are approved. The application asks for a legally formed entity, and applying too early creates a mismatch between your EIN records and your corporation. Incorporate first, then get the EIN.

Getting more than one EIN

An organization needs exactly one EIN. If you accidentally apply twice, you end up with duplicate numbers, which causes confusion on filings and with the IRS. Apply once, record the number carefully, and store the confirmation.

Paying a third party for the number itself

The EIN is free directly from the IRS. Be wary of sites that charge a fee for "obtaining" an EIN as if it were a government charge — the number itself costs nothing. A filing service may include EIN acquisition as part of a bundled formation package for convenience, but the underlying EIN is never a paid government item.

Losing the confirmation

Save the CP 575 confirmation notice somewhere permanent. You'll need the EIN repeatedly — for the exemption application, banking, 990 filings, and grants. If you lose the notice, you can retrieve the number from the IRS, but it's far easier to keep the original.

With the EIN in hand, your nonprofit can move through the rest of the setup. Open the organization's bank account so funds are kept entirely separate from any individual — a cornerstone of both liability protection and good nonprofit governance. Then use the EIN on your Form 1023 or 1023-EZ to apply for 501(c)(3) status.

From there, the EIN becomes a permanent fixture of your organization's identity. It appears on every Form 990 you file, on grant applications, on donation receipts, and on any employment tax filings if you have staff. It stays with the nonprofit for its entire existence — you don't renew it, and it doesn't change unless the organization's structure fundamentally changes. Getting it right once, at the correct point in the formation sequence, is all it takes.
