Step 5: Get an EIN

What is an EIN? An EIN or Employer Identification Number is a nine-digit number issued by the Internal Revenue System (IRS) to identify a business for tax reporting purposes. An EIN is essentially a Social Security number (SSN) for your company.

Free EIN: You can get an EIN from the IRS website (free of charge) after forming your business.

Step 6: File the Annual Report

Connecticut requires LLCs to file an annual report with the Connecticut Secretary of State. This updates your LLC's basic information with the state.

Annual reports are due by March 31 each year and can be filed online with the CT.gov platform, along with the $80 filing fee. Any annual report received after March 31 will give your LLC a "Not in Good Standing" status with the state.

Step 7: Keep Your Company Compliant

Keeping your LLC compliant in Connecticut involves several key steps. Here's a brief rundown of the most critical points:

  • Business Licenses & Permits: Your LLC needs to adhere to federal, state, and local regulations. The necessary licenses and permits, as well as their respective fees, depend on your business type.
  • Connecticut LLC Tax Obligations: It's crucial to stay updated with Connecticut's tax laws. These include the 6.35% state sales tax for selling physical goods, employer taxes for businesses with employees, and the graduated state income tax, ranging from 3% to 6.99% based on your LLC's income.
  • Employee Hiring Compliance: If you're hiring employees for your LLC, ensure their eligibility to work in the US, report them as new hires to the state, provide workers' compensation insurance, handle tax withholdings, and display workplace compliance posters prominently.

Each of these elements plays an important role in ensuring compliance for your Connecticut LLC. The focus ranges from securing the appropriate licenses and permits to understanding tax requirements, highlighting the multifaceted nature of operating an LLC in Connecticut.
