EIN Guide for a Maine Nonprofit Corporation

An Employer Identification Number is a nine-digit number the IRS assigns to identify your organization for federal tax purposes. Think of it as a Social Security number for your nonprofit — a unique identifier that follows the corporation throughout its life. The name is a little misleading: you need an EIN whether or not you ever have a single employee.

Every Maine nonprofit corporation needs an EIN, and it's one of the first things you do after the state records your Articles of Incorporation. Here's why it's not optional:

• Bank accounts — no bank will open a business account for your nonprofit without an EIN.
• Tax-exempt application — the IRS requires your EIN before you can apply for 501(c)(3) status on Form 1023 or 1023-EZ.
• Employees and contractors — if you hire staff or pay contractors, you need the EIN for payroll and reporting.
• General identity — grantmakers, vendors, and donors identify your organization by its EIN.

Without an EIN, your nonprofit essentially can't function financially. It can exist on paper as a Maine corporation, but it can't hold money, apply for exemption, or operate in any practical sense.

The sequence of formation steps matters, and the EIN sits at a specific point in it. Apply for the EIN after your nonprofit is legally formed in Maine, but before you open a bank account or file for tax exemption.

Incorporate first

Get your Articles of Incorporation accepted by the Maine Bureau of Corporations first. The EIN application asks for your legal entity name and formation details, so it's cleaner to have the corporation officially in existence before you apply. Applying before you're formed can create mismatches between what the IRS has on record and what Maine has.

Then get the EIN

With the corporation formed, apply for the EIN. It's fast and free, and you'll have the number the same day.

Then everything downstream

Once you have the EIN, you can open your bank account, apply to the IRS for exempt status, register for any state tax accounts, and set up payroll if you have staff. The EIN is the key that unlocks all of those steps, which is why it comes early but not first.

Applying for an EIN is genuinely simple and completely free through the IRS. Don't pay a third party specifically for this step, because the government charges nothing.

The online application

1. Go to the IRS EIN Assistant. It's available during posted hours, generally on weekdays.
2. Select that you're applying for a nonprofit or other organization type, matching your actual structure.
3. Enter your legal entity name exactly as it appears on your Maine Articles of Incorporation, and your Maine formation details.
4. Name a responsible party — an individual who controls or manages the organization, typically a board officer like the president or treasurer, using their SSN or ITIN.
5. Submit. The system issues your EIN immediately, and you can download and print the confirmation notice on the spot.

If you can't apply online

If the responsible party lacks an SSN or ITIN, or you'd rather not use the online tool, you can apply by fax or mail using Form SS-4. Those methods take longer — days by fax, weeks by mail — so the online route is preferable whenever it's available to you.

Most EIN problems are avoidable and come down to a handful of recurring errors. Knowing them in advance saves you headaches later.

Paying for a free service

The number one mistake is paying a company that charges a fee "to get your EIN." The IRS issues EINs at no cost. If you go directly to the IRS site, you'll never pay for this step.

Applying before the corporation exists

Applying for the EIN before Maine has recorded your Articles can create a mismatch between IRS and state records. Form the corporation first, then apply, so the legal name and details line up.

Name mismatches

Enter your organization's legal name exactly as it appears on your Maine Articles of Incorporation. A discrepancy between your EIN records and your state records can cause friction with banks and complicate your IRS exemption application down the line.

Choosing the wrong responsible party

The responsible party should be a real person who genuinely controls the organization — usually a board officer — not a placeholder or an unrelated volunteer. The IRS uses this designation as its accountable contact, so pick appropriately and keep it updated if leadership changes.

Losing the confirmation

When the IRS issues your EIN, download and save the confirmation notice immediately. You'll be asked for it by your bank and on your exemption application. Retrieving a lost EIN confirmation is possible but slower than just keeping the original in your records.

New founders sometimes assume the EIN carries more weight than it does. Understanding exactly what it means keeps your expectations accurate as you move through formation.

An EIN is not tax-exempt status

This is the most important distinction. Getting an EIN does not make your nonprofit tax-exempt, and it doesn't make donations deductible. The EIN simply identifies your organization to the IRS. Tax exemption is a separate approval you earn later by filing Form 1023 or 1023-EZ. Plenty of organizations have an EIN and are not (or not yet) exempt — the two are unrelated milestones.

An EIN is not a business license

The EIN is a federal tax identifier, not permission to operate. It doesn't satisfy Maine's charitable solicitation registration, it isn't a state tax account, and it doesn't replace any license or permit your specific activities might require. Think of it as one piece of identification, not a green light for everything.

The EIN follows the corporation for life

Once issued, your EIN stays with the corporation permanently. You don't get a new one when your board changes, when you move, or when you finally receive 501(c)(3) recognition. The only time a nonprofit typically needs a new EIN is if it's a genuinely new legal entity — for example, if you dissolve and later form a completely separate corporation. Keep the number consistent across your bank records, IRS filings, and grant applications so nothing gets crossed.

Once the number is in hand, it becomes part of your organization's everyday financial identity. A few practical points help you use it well.

Where the EIN shows up

• On your business bank account application and account records.
• On your Form 1023 or 1023-EZ exemption application.
• On your annual Form 990 filings.
• On W-9 forms you provide to grantmakers and payers.
• On payroll and contractor paperwork if you have staff.

Keep it findable but protected

Store the confirmation notice where your treasurer and key officers can retrieve it, but don't broadcast the number carelessly. While an EIN isn't as sensitive as an individual's Social Security number, it's still an identifier that shouldn't be posted publicly without reason. A simple rule: keep it with your permanent corporate records, alongside your Articles of Incorporation and bylaws, so anyone who legitimately needs it can find it fast.
