How to Get an EIN for Your Solo Founder Business in Connecticut (2026)

As a solo founder in Connecticut, obtaining an Employer Identification Number (EIN) is a crucial step for legitimizing and growing your business. This guide will walk you through the process of acquiring an EIN in 2026, ensuring you're set up for success. Let Lovie handle the complexities, so you can focus on your vision.

What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business. While sole proprietorships without employees can often use their SSN, single-member LLCs and corporations typically require an EIN for tax purposes and to separate personal and business finances.

How to Apply for an EIN

Determine Eligibility: Confirm that your solo founder business structure requires an EIN. Single-member LLCs and those planning to hire employees in Connecticut generally need one.
Choose a Business Structure: Decide on your business structure (e.g., single-member LLC). This decision impacts your tax obligations and liability. In Connecticut, LLCs are popular for their flexibility and liability protection.
Gather Required Information: You'll need your personal information (SSN), business name, business address (can be your home address in Connecticut), and the reason for applying for the EIN.
Complete the IRS Form SS-4: The application for an EIN is done via IRS Form SS-4. You can download it from the IRS website or complete the application online through the IRS EIN Assistant.
Submit Your Application: You can apply for an EIN online, by fax, or by mail. The online application is the fastest method and is generally recommended.
Receive and Store Your EIN: Once your application is approved, you'll receive your EIN. Keep this number in a safe place, as you'll need it for various business-related activities.
