Getting an EIN for Your New Mexico Nonprofit

An Employer Identification Number is a nine-digit number the IRS assigns to identify an organization for federal tax purposes. Think of it as a Social Security number for your nonprofit — it's how the federal government, banks, and other institutions recognize the organization as a distinct entity.

Every nonprofit needs one, employees or not

The word "employer" in the name is misleading. Your nonprofit needs an EIN even if it never hires a single employee. You can't open a bank account in the organization's name without one, you can't apply for federal tax-exempt status without one, and you generally can't file the required annual returns without one. For a nonprofit, the EIN is foundational infrastructure, not an optional extra.

Where the EIN fits in your formation sequence

Get the EIN after your New Mexico incorporation but before your IRS exemption application and before opening a bank account. The order matters: you want the corporation to legally exist first, and you need the EIN in hand for both the 501(c)(3) application and the bank. Founders sometimes try to get an EIN before incorporating, which creates confusion about the entity's legal name and status.

The single most important thing to know about EINs is that they are free. The IRS issues them at no cost, and any service charging you specifically for the EIN itself is marking up something the government gives away.

The online application

Your quickest option is the IRS EIN Assistant, hosted at IRS.gov. The online application is available during posted hours, takes roughly ten minutes, and issues your EIN immediately upon completion — you can download the confirmation and use the number the same day. This is the method most New Mexico nonprofits should use.

Requirements to apply online

• The application must be completed in a single session; it times out if you step away too long
• You'll need a responsible party with a valid Social Security number or ITIN
• The organization should already be formed, so you can enter its legal name and formation details accurately

Alternatives to online filing

If the responsible party lacks an SSN or ITIN, or the organization otherwise can't use the online tool, you can apply by fax or mail using Form SS-4. These methods take longer — days to weeks rather than minutes — so use the online tool whenever you're eligible.

The EIN application asks a few questions that trip up nonprofit founders because the answers differ from what a for-profit would enter.

Entity type

When the application asks what type of entity you are, you'll indicate a nonprofit or church-controlled organization as applicable, or otherwise select the option that reflects a tax-exempt purpose rather than a for-profit corporation or LLC. Choosing the wrong entity type can create mismatches with your later 501(c)(3) application, so answer this one carefully.

The responsible party

Every EIN application names a "responsible party" — the individual who ultimately controls or directs the organization. For a nonprofit, this should generally be a principal officer, such as the board president or executive director, not an outside filer or a service. The responsible party's SSN or ITIN is used to verify the application; it doesn't make that person an owner, because nonprofits have no owners.

Reason for applying

You'll typically indicate that you're applying because you started a new organization. If you're getting the EIN as part of forming the nonprofit, that's the accurate reason.

A few recurring errors cause headaches down the line. Knowing them in advance saves you from correcting the record later.

Getting the EIN before incorporating

If you apply for an EIN before the nonprofit legally exists in New Mexico, the entity name and details you enter may not match your Articles of Incorporation. Incorporate first, then get the EIN using the exact legal name on your filed Articles.

Paying a third party for the number itself

The EIN is free from the IRS. Some services bundle "EIN assistance" as a paid add-on. There's nothing wrong with paying a filing service to handle your overall formation, but be clear that the EIN itself carries no government fee, and don't pay a standalone charge for a number the IRS issues for free.

Applying more than once

Your nonprofit needs exactly one EIN, and it keeps that number for its entire existence. Don't apply again if you can't find your confirmation — retrieve the existing number instead. Multiple EINs for one organization create genuine confusion with the IRS and with banks.

Losing the confirmation letter

The IRS issues an EIN confirmation (the CP 575 for new applications) that banks and grantmakers may ask to see. Save a digital and physical copy the moment you receive it. Replacing a lost confirmation is possible but slower than simply keeping the original safe.

The EIN unlocks the next stages of building your nonprofit's infrastructure.

Open a bank account

With your filed Articles of Incorporation, your EIN confirmation, and your bylaws, you can open a bank account in the nonprofit's name. Keeping the organization's finances entirely separate from any individual's personal accounts is essential — commingling undermines both the corporate structure and the organization's credibility with funders and auditors.

Apply for 501(c)(3) status

Your EIN goes on your Form 1023 or Form 1023-EZ exemption application. The IRS uses it to tie your exemption to the correct entity. You cannot apply for federal tax exemption without an EIN, which is why it comes first in the federal sequence.

Use it on all federal filings

Every Form 990 series return, every payroll filing if you have employees, and every federal document tied to the organization carries the EIN. It becomes the organization's permanent federal identifier for as long as the nonprofit exists.
