What is an EIN?

An EIN, or Employer Identification Number, is like a Social Security number for your business. It's a unique tax ID assigned by the IRS to identify your agency for tax purposes. You'll need an EIN to hire employees, open a business bank account, and file certain taxes.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Connecticut agency business structure requires an EIN. LLCs with employees, corporations, and partnerships generally need one.
  2. Gather Required Information: Collect information such as your agency's legal name, business address in Connecticut, the responsible party's (owner, partner, officer) name and SSN, and the reason for applying.
  3. Complete Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. You can download the form from the IRS website or complete the application online.
  4. Submit Your Application: You can apply for an EIN online through the IRS website, by mail, by fax, or via telephone (for international applicants only). Online application is the fastest method.
  5. Receive Your EIN: If you apply online, you'll typically receive your EIN immediately. If applying by mail or fax, it can take several weeks.
  6. Notify Connecticut State Agencies: Inform relevant Connecticut state agencies, such as the Department of Revenue Services, about your new EIN. This ensures proper tax reporting at the state level.
