How to Get an EIN in New Jersey

An Employer Identification Number (EIN) is your business's federal tax ID. If you're starting a business in New Jersey, an EIN is often one of the first things you'll need, whether you're hiring employees, forming an LLC, or just want a separate tax identity from your personal Social Security number. The good news: the application is free and can be done online in minutes.

What Is an EIN and Why You Need One

An EIN (also called a Federal Employer Identification Number or FEIN) is a nine-digit number assigned by the Internal Revenue Service to identify your business for tax purposes. It works like a Social Security number for your company.

Even if you're a sole proprietor with no employees, you may need an EIN. You'll definitely need one if you:

  • Are hiring employees (required)
  • Have formed an LLC, S-corp, or C-corporation
  • Have a partnership
  • Operate as a nonprofit or trust
  • Want to keep your personal Social Security number off business accounts and contracts

Sole proprietors without employees can use their Social Security number, but most business owners get an EIN anyway for privacy and formality.

What You'll Need Before Applying

Gather these materials before you start the application:

  • Legal business name (exactly as it appears on your formation documents)
  • Business structure (LLC, corporation, partnership, sole proprietorship, etc.)
  • New Jersey street address (the physical location where your business operates or is managed; PO boxes don't count)
  • Responsible party information (usually the owner, manager, or someone authorized to speak for the business, including their name, title, SSN, and date of birth)
  • Expected business start date
  • Business type or industry code (general category of what you do)
  • Your state formation documents (Articles of Organization for an LLC, Certificate of Incorporation for a corporation, or similar, if you've already filed with New Jersey)

If you haven't formed your business in New Jersey yet, that's okay. You can apply for an EIN before or after state formation. However, most people file their LLC formation or corporate formation with the state first, then get their EIN.

Step-by-Step Process to Get Your EIN

Step 1: Go to the IRS Website

Visit the IRS's official EIN application page at irs.gov/ein or go directly to the online EIN application at irs.gov/eins. Do not use third-party websites that charge fees, the IRS application is completely free.

Step 2: Choose Your Application Method

The IRS offers several ways to apply for an EIN:

  • Online (fastest): Immediate confirmation, takes 5 to 10 minutes. This is the standard choice for New Jersey businesses. Your EIN is assigned on the spot.
  • By phone: Call 1-800-829-4933. Hours are Monday to Friday, 7:00 a.m. to 10:00 p.m. Eastern Time. You'll receive your EIN on the call.
  • By mail: Fill out Form SS-4 and mail it to the IRS. This takes 4 to 6 weeks. Only use this if you can't apply online or by phone.
  • By fax (no longer available as of 2024): The IRS stopped accepting faxed Form SS-4 applications.

For New Jersey businesses, the online application is strongly recommended. It's fast, and you get your EIN instantly to use on bank accounts and tax forms immediately.

Step 3: Complete the Online Form

If applying online, the IRS presents an interactive form. Here's what you'll enter:

  • Responsible party: The individual (usually the owner or manager) authorized to represent the business. Enter their legal name, date of birth, and Social Security number.
  • Business name: Your legal business name exactly as it appears on your formation documents or business license. If you do business under a different name (like a DBA or alternate name registration), you'll list that separately.
  • Business address: Your physical New Jersey street address (not a PO box). If you have a separate mailing address, you can provide that too.
  • Business structure: Select from the dropdown: Corporation, Partnership, S-Corporation, Sole Proprietorship, Trust, LLC (and choose if it's single-member or multi-member), Nonprofit, or other.
  • Business activity/industry: Describe what your business does (e.g., "Photography services," "Plumbing contractor," "Consulting").
  • Expected business start date: When you expect to open or have already opened for business.
  • Number of employees: How many people you'll employ (if hiring employees is why you're getting the EIN, put that number; if zero, enter zero).
  • Reason for applying: If this is a new business, select that. If you're applying because you've hired employees or changed structure, select the appropriate reason.

The form is straightforward. Answer accurately; the IRS is not looking to trip you up. They just need basic information to assign your number and create a tax file.

Step 4: Submit and Confirm

After you complete the form, click Submit. If everything is valid, the IRS will display your new EIN on the screen within seconds. Screenshot or print this page immediately. Write down your EIN in a safe place.

You'll also be able to download a confirmation letter (also called a "Notice of EIN Assignment"). Download this and save it. You may need to show it to:

  • Banks when opening a business account
  • The New Jersey Department of Revenue (when you file your NJ-REG form)
  • Vendors or clients requesting proof of your business tax ID

Step 5: Register with New Jersey

Getting a federal EIN is just the first step. You also need to register with the State of New Jersey for tax and employment purposes. After you get your EIN, file the NJ-REG (New Jersey Business Registration Application) with the New Jersey Division of Revenue and Enterprise Services.

The NJ-REG is what:

  • Registers your business with the state for income tax
  • Obtains your New Jersey tax identification number (different from your EIN)
  • Gets you a sales tax certificate of authority if you're selling taxable goods or services
  • Registers you for payroll withholding if you have employees

You can file NJ-REG online at https://www.njportal.com/DOR/BusinessRegistration/. You'll need your EIN for this application. Registration is free. The state typically processes it within a few business days, and you'll receive your New Jersey tax ID number by email.

Timeline: When Will You Get Your EIN?

  • Online application: Immediate. Your EIN is assigned and displayed on screen the moment you submit.
  • Phone application: Immediate. You'll be given your EIN during the call.
  • Mail application: 4 to 6 weeks. Avoid this unless you have no other option.

Once you have your EIN, you can open a business bank account, hire employees, and file taxes the same day if needed. There's no waiting period.

Common Mistakes to Avoid

  • Using a third-party service. Websites advertise "We'll get your EIN for you" and charge $50 to $300. This is unnecessary. The IRS application is free and takes five minutes. Skip the middleman.
  • Using the wrong business name. Make sure your EIN application name matches your New Jersey formation documents (your LLC Articles of Organization, Certificate of Incorporation, or DBA filing). Mismatches create headaches when filing taxes.
  • Listing a PO box as your address. The IRS requires a physical street address where your business operates or is managed. A PO box alone will be rejected. If you work from home, use your home address.
  • Forgetting to register with New Jersey. Your federal EIN is not the same as a New Jersey tax ID. You must also file NJ-REG to be registered with the state. Many new business owners skip this and later face penalties.
  • Not saving your confirmation. Print or screenshot your EIN confirmation letter. Banks, accountants, and the state may ask for proof of your EIN. Losing it means requesting another from the IRS (usually free but slower).
  • Applying with incomplete or inaccurate information. Double-check names, addresses, and dates before submitting. Errors can slow down processing or result in an incorrect assignment.

What to Do After You Get Your EIN

Your EIN is live as soon as it's assigned. Here's what comes next:

  • File NJ-REG: Register with New Jersey within 5 to 10 business days of getting your EIN (or before you start business, whichever is earlier).
  • Open a business bank account. Bring your EIN confirmation letter and a government-issued ID to your bank. This separates your business finances from personal finances.
  • Set up payroll (if hiring employees). If you have employees, you'll need to set up payroll withholding with both the federal IRS and the New Jersey Division of Taxation. The forms are available on their respective websites.
  • Get business licenses. Depending on your industry, you may need specific licenses or permits from the state or your municipality. Check with your local business licensing office to be sure.
  • Set up accounting. Even if you're not required to, keeping clean financial records from day one saves headaches at tax time. Many small business owners use accounting software like QuickBooks or work with a CPA.

Tips for a Smooth Process

  • Apply online during business hours. The online system is available 24/7, but the IRS's backend runs fastest during regular business hours (8:00 a.m. to 5:00 p.m. Eastern Time, weekdays).
  • Use your actual responsible party's information. The "responsible party" is typically the owner or a manager. Don't try to hide behind a middle person; the IRS wants the person actually in charge.
  • Have a New Jersey address ready. If you're working from home, that's fine. If you're leasing an office, have the lease or letter from the landlord confirming your tenancy. The IRS doesn't verify addresses at application time, but you should be able to prove it if asked later.
  • Don't overthink the business description. "Plumbing services" is fine. You don't need to write "Residential and commercial plumbing installation, repair, and maintenance services." Keep it simple and clear.
  • Combine this with your state formation. If you haven't already, file your LLC or corporation with the state around the same time you apply for your EIN. It makes the whole process more efficient.

Do You Need a CPA or Attorney?

Getting an EIN is straightforward enough to do yourself with no professional help. However, if you're unsure about your business structure, tax strategy, or compliance requirements, it's worth consulting a CPA or attorney before or immediately after filing. They can make sure you're set up correctly from the start, which saves money and headaches later.
