Quick Facts
What Is an EIN?
An Employer Identification Number (EIN), also known as a Federal Tax Identification Number or Federal Employer Identification Number (FEIN), is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States. The format is XX-XXXXXXX. Think of it as a Social Security Number for your business — it identifies your business entity for all federal tax purposes.
Every LLC, corporation, partnership, and most other business entities in New Jersey need an EIN. Even single-member LLCs that are treated as disregarded entities for tax purposes benefit from having an EIN because it allows you to keep your personal Social Security Number off business documents, invoices, and tax forms. This provides an important layer of identity protection.
The EIN is issued by the IRS at no cost. Unlike state filing fees, which vary (for example, the New Jersey LLC filing fee is $125), the EIN application is always free. You apply directly with the IRS, and if you use the online application, you receive your number instantly. Your EIN stays with your business entity for its entire lifetime — it does not expire or need to be renewed.
Do You Need an EIN in New Jersey?
The IRS requires you to have an EIN if any of the following apply to your New Jersey business. Even if you are not technically required to have one, getting an EIN is strongly recommended for every business entity.
You Have or Will Hire Employees
Any New Jersey business with employees must have an EIN to report payroll taxes, withhold federal income tax, and file W-2 forms. This is a strict IRS requirement with no exceptions.
You Operate as an LLC or Corporation
Multi-member LLCs taxed as partnerships and all corporations must have an EIN. Single-member LLCs are not strictly required to have one but should get one anyway for banking, identity protection, and if they ever plan to add members or hire employees.
You Want to Open a Business Bank Account
Every bank in New Jerseyrequires an EIN to open a business checking or savings account for an LLC or corporation. Without an EIN, you cannot separate your personal and business finances, which is essential for maintaining your entity's liability protection.
You File Federal Business Tax Returns
Your EIN is used on all federal business tax returns, including Form 1065 (partnerships and multi-member LLCs), Form 1120 (C-Corps), Form 1120-S (S-Corps), and employment tax returns. Even if your LLC is a disregarded entity, having an EIN on your Schedule C adds professionalism and protects your SSN.
You Want to Build Business Credit
Your EIN is linked to your business credit profile with agencies like Dun & Bradstreet, Experian Business, and Equifax Business. Establishing business credit in New Jersey starts with having an EIN and using it consistently on business accounts and credit applications.
How to Apply for an EIN in New Jersey
Follow these steps to obtain your EIN from the IRS. The process is the same regardless of which state you formed your business in — the EIN is a federal identification number, not a state one. However, your New Jersey business details are required on the application.
- 1
Form Your Business Entity First
Before applying for an EIN, you should have your New Jersey LLC or corporation officially formed with the New Jersey Secretary of State. The IRS requires your entity's legal name, formation date, and state of organization on the EIN application. If you have not yet formed your entity, start with our New Jersey LLC formation guide. FormifyAI forms your entity and applies for your EIN in one seamless process.

Gather Your Information
To apply for an EIN, you will need: (1) your entity's legal name exactly as it appears on your New Jersey formation documents; (2) your entity type (LLC, corporation, partnership, etc.); (3) the reason for applying (new business, hiring employees, banking purposes, etc.); (4) the responsible party's name and SSN or ITIN — this is typically the LLC member or corporate officer who controls the entity; (5) your business mailing address; and (6) your New Jersey business address if different from the mailing address.

Apply Online via the IRS EIN Assistant
Visit the IRS EIN Online Assistant at irs.gov (search for "EIN application" or navigate to the Apply for an Employer Identification Number section). The online application walks you through a series of questions about your entity type, responsible party, and business details. The process takes about 10 to 15 minutes. The online assistant is available Monday through Friday, 7:00 AM to 10:00 PM Eastern Time. Upon successful completion, your EIN is issued immediately.

Download Your EIN Confirmation
After completing the online application, you will see a confirmation page displaying your new EIN. Download or print this confirmation immediately — it serves as your official EIN assignment notice. The IRS will also mail you a formal confirmation letter (CP 575) to your business address within 4 to 6 weeks. Keep both the online confirmation and the CP 575 letter in your business records. You will need your EIN to open a bank account, which is typically the next step.

Open a Business Bank Account
With your EIN in hand, you can open a business bank account for your New Jersey LLC or corporation. Banks typically require your EIN confirmation, your formation documents (Articles of Organization or Certificate of Formation), your operating agreement (for LLCs), and a government-issued photo ID. Having a separate business bank account is essential for maintaining the liability protection your LLC or corporation provides — mixing personal and business funds can "pierce the corporate veil."

Register for State Taxes
New Jersey has both a state income tax and a sales tax. After getting your EIN, you will likely need to register with the New Jersey Department of Revenue for state tax purposes, including income tax withholding (if you have employees) and a sales tax permit (if you sell taxable goods or services). Your EIN is typically required as part of the state tax registration process. FormifyAI's compliance dashboard helps you identify which state tax registrations are required for your specific business type and location in New Jersey.
EIN vs SSN vs ITIN
Understanding the differences between these three tax identification numbers helps you use each one correctly for your New Jersey business.
| Feature | EIN | SSN | ITIN |
|---|---|---|---|
| Issued To | Business entities | U.S. citizens & permanent residents | Non-residents & foreign nationals |
| Format | XX-XXXXXXX | XXX-XX-XXXX | 9XX-XX-XXXX |
| Cost | Free | Free | Free |
| Used For | Business taxes, banking, hiring | Personal taxes, employment, credit | Personal taxes (non-residents) |
| Expires | Never | Never | After 3 years of non-use |
For your New Jersey business, you will use your EIN on all business-related tax documents, bank accounts, and government filings. Your SSN or ITIN is used on your personal tax return. Using your EIN instead of your SSN on business documents helps protect your personal identity and keeps your finances properly separated.
What to Do After Getting Your EIN
Once you have your EIN, there are several important steps to set up your New Jersey business properly. These steps help you stay compliant and begin operating.
Open a Business Bank Account
Visit a bank in New Jersey with your EIN confirmation letter, formation documents, operating agreement (for LLCs), and government-issued photo ID. A dedicated business bank account is essential for maintaining your liability protection and keeping clean financial records. Most banks in New Jersey can open your account the same day.
Register for State Taxes
New Jersey has both a state income tax and a sales tax. After getting your EIN, you will likely need to register with the New Jersey Department of Revenue for state tax purposes, including income tax withholding (if you have employees) and a sales tax permit (if you sell taxable goods or services).State tax registration is separate from your federal EIN and must be completed with the state directly. FormifyAI's compliance dashboard identifies which state tax registrations are required for your business.
Set Up Payroll (If Hiring Employees)
If you plan to hire employees in New Jersey, use your EIN to register for payroll taxes with the IRS and the New Jersey Department of Revenue. You will need to withhold federal income tax, Social Security, Medicare, and applicable state taxes from employee paychecks.
Apply for Business Licenses and Permits
Many business licenses and permits in New Jerseyrequire your EIN as part of the application. Check with your local city and county clerk's office and the New Jersey state licensing boards to determine which licenses your specific business needs.
Start Building Business Credit
Register your New Jerseybusiness with Dun & Bradstreet to get a D-U-N-S Number, which is linked to your EIN. Open business credit accounts and vendor accounts under your EIN to establish a business credit profile separate from your personal credit. Strong business credit helps you access better financing terms as your business grows.
