What Is an EIN & Why Does Your New Haven Business Need One?

An Employer Identification Number (EIN) is a nine-digit number assigned by the IRS to businesses for tax purposes. Think of it as your company’s social security number — it’s required for hiring staff, paying federal taxes, and even opening many business bank accounts. In New Haven, whether you’re registering a food truck, LLC, partnership, or corporation, an EIN is a must-have for legal and financial operations.

Who Should Apply for an EIN in New Haven?

Not sure if you need to get an EIN number? Here’s a quick checklist for New Haven business owners:

• Hiring employees (even just one)
• Forming an LLC, corporation, or partnership
• Opening a business bank account (most New Haven banks require it)
• Applying for local or state business licenses
• Withholding taxes on income, other than wages, paid to a non-resident alien
• Establishing a trust, estate, nonprofit, or certain pension plans

Even sole proprietors sometimes benefit from having an EIN, especially if they want to keep personal and business finances separate.

How to Get an EIN Number in New Haven: Step-by-Step

1. Gather your business details:
   • Legal business name and address (use your New Haven address)
   • Business structure (LLC, corporation, sole proprietorship, etc.)
   • Responsible party’s name and SSN or ITIN
2. Decide how to apply:
   • Apply online via the IRS website (available weekdays, typically 7 a.m.–10 p.m. EST)
   • Mail or fax IRS Form SS-4 to the appropriate IRS address
   • Work with a paid service for a guided, reviewed application process
3. Submit your application: Double-check all New Haven addresses and business information to avoid processing delays.
4. Receive your EIN: If you apply online, you typically get your EIN immediately. Mailed or faxed applications may take longer.

Be sure to keep your EIN confirmation letter in a safe spot—you’ll need it for city permits, state licenses, and tax filings in Connecticut.

Tips & Common Mistakes to Avoid When Applying

• Don’t use a PO Box as your principal business address—the IRS requires a physical New Haven address.
• Double-check the spelling of your business name to match Connecticut Secretary of State records if you’ve registered your entity.
• Only one EIN per responsible party per day is allowed online, so plan accordingly if you’re opening multiple businesses.
• If you’re unsure about your business structure, consult a local advisor or the CTNext resource network.
