EIN Guide for a Nevada Corporation

An Employer Identification Number is a nine-digit number the IRS assigns to identify a business for federal tax purposes. It is the business equivalent of a Social Security number — a permanent identifier the IRS uses to track the entity's tax accounts.

Why a corporation always needs an EIN

Unlike a single-member LLC, which can sometimes use the owner's Social Security number, a corporation always needs its own EIN. That is because a corporation is a separate taxpayer: it files its own federal return distinct from its owners. A C-corporation files Form 1120 and pays tax at the entity level; a corporation that elects S-corporation status files Form 1120-S and passes income through to shareholders. Either way, the corporation needs its own federal tax ID from day one.

What you use the EIN for

• Filing the corporation's federal income tax return
• Opening a corporate bank account — banks require the EIN
• Hiring employees and running payroll, including withholding and employment taxes
• Applying for business licenses and permits that ask for a federal tax ID
• Setting up merchant accounts and other financial relationships

The EIN belongs to the corporation, not to you personally. It stays with the entity for its entire life and is never reassigned to another business, even after dissolution.

Timing matters. The EIN is a federal identifier, and it makes sense to get it in the right sequence relative to forming the corporation with Nevada.

Form the corporation first

Apply for the EIN after the Nevada Secretary of State has accepted your Articles of Incorporation, so the corporation legally exists and its name and details are settled. The EIN application asks for the entity's legal name and formation state, and those should match your filed Articles. Applying before the corporation exists can create mismatches you will have to untangle later.

Then bank and hire

Once you have the EIN, you can open the corporate bank account, set up payroll if you are hiring, and complete other financial setup. The EIN is often the gating item — you cannot open the account without it — so getting it promptly after formation keeps the rest of your setup moving.

The IRS issues EINs at no cost. Be wary of any site that charges a fee simply to "get" an EIN — the number itself is always free directly from the IRS. The fastest route is the online application.

The online process

1. Go to the EIN Assistant on IRS.gov during its operating hours.
2. Select the entity type — corporation — and answer the prompts about the business.
3. Provide the corporation's legal name and Nevada formation details, matching your Articles of Incorporation.
4. Identify the responsible party, which requires a valid US Social Security number or ITIN.
5. Submit, and the EIN is issued immediately on screen.

What you get

The application takes roughly ten minutes, and the EIN is issued instantly. You can download and print the confirmation notice and start using the number the same day — including at the bank. Save that confirmation; it is the official proof of your EIN and banks and agencies often ask for it.

The responsible party

The IRS requires you to name a responsible party — generally the individual who controls or manages the corporation. For online applications, that person needs a US Social Security number or ITIN. Only one EIN is issued per responsible party per day through the online tool.

Foreign founders can and do form Nevada corporations, and they can obtain an EIN — the process is just different because the online tool requires a US taxpayer ID for the responsible party.

Form SS-4 by fax or mail

If the responsible party does not have a US Social Security number or ITIN, you cannot use the instant online tool. Instead, complete Form SS-4, the paper EIN application, and submit it to the IRS by fax or mail. On the form, where a US taxpayer ID would go for the responsible party, foreign applicants can write "Foreign" per the IRS instructions.

Timing for foreign applicants

Fax applications typically come back within about a week; mailed applications take longer. Some foreign founders also apply by phone through the IRS's international line. Because this route is slower than the instant online tool, non-US founders should start the EIN process early so it does not hold up banking and other setup.

No ITIN required just for the EIN

A common misconception is that a foreign founder must first obtain an ITIN before getting an EIN. That is not the case — you can obtain the corporation's EIN with Form SS-4 without an ITIN. Whether you personally need an ITIN is a separate question tied to your own US tax situation.

A few recurring errors cause headaches. Knowing them ahead of time saves you from redoing paperwork or fielding IRS notices.

Mistakes to watch for

• Paying a third party for the number itself: The EIN is free from the IRS. A legitimate service may charge for handling the paperwork, but the number is never something you must pay the government for.
• Applying before the corporation exists: Wait until Nevada accepts your Articles so the entity name and details match.
• Name mismatches: The name on the EIN application should match the corporation's exact legal name on the Articles of Incorporation. Discrepancies cause problems at the bank and with the IRS.
• Requesting more than one EIN unnecessarily: A corporation needs only one EIN. Applying again because you misplaced the confirmation just creates duplicate records — instead, retrieve the original.
• Losing the confirmation: Save the EIN confirmation notice. If you lose it, you can call the IRS Business and Specialty Tax Line to have your number confirmed.

Getting the EIN right the first time is straightforward once you have your Articles accepted and your responsible party's information ready. It is one of the simpler steps in launching a corporation, and it unlocks banking and hiring.
