Establish Company Records
Your filed articles of organization are the first document for your limited liability company records. Your LLC will generate many other official records such as your operating agreement, meeting minutes, and your EIN.
Office supplies intended for an LLC will help you stay organized and save time. Membership certificate templates should come with your company record book. Each owner receives a membership certificate as evidence of his or her ownership in the LLC.
Create the Operating Agreement
Draft an Operating Agreement (potentially using a template) which is the governing document for the LLC. It defines the formalities of how the LLC will run itself such as holding an annual meeting. You will review and adopt the agreement at your organizational meeting.
Hold the Organizational Meeting
The first meeting of the members of the LLC is the organizational meeting. You will need your filed articles of organization and your operating agreement in order to conduct this meeting. Keep minutes of this meeting and store them in your company record book.
Get a Federal Employer Identification Number (EIN)
If your LLC has more than one member or will hire employees, it must obtain an EIN. An EIN is also often required to open a bank account.
Agency: Internal Revenue Service (IRS) Form: Filing Method:
Mail, phone, fax, or online.
Immediately online or by phone. 4 business days by fax. 4-5 weeks by mail.
The IRS website is only available during certain hours. Print your EIN before closing your session. For additional guidance, see IRS Pub 1635: Understanding Your EIN.

Consider Electing S-Corp or C-Corp Taxation
By default, your LLC receives pass-through taxation and the vast majority of LLCs keep this tax classification. Some LLCs benefit from electing S-Corp or C-Corp tax treatment:
- S-Corp treatment can help owner-employees who earn more than ~$75,000 per year save on self-employment taxes. File Form 2553: S-Corp Election.
- C-Corps suffer from double taxation: the corporation pays taxes on profits then members pay taxes on their distributions. If profits exceed $250,000 per owner, you provide employee benefits, or you will re-invest most of your profit in the business, you may benefit from the low tax rates on retained earnings under C-Corp treatment. File Form 8832: C-Corp Election.
Obtain Business Licenses & Permits
To run your business legally, you must obtain applicable licenses and permits. The easiest way to navigate the wide range of federal, state, and local requirements is to search by your business type and locality using the Small Business Administration Business License & Permit look-up tool.
- Connecticut LLCs file an Annual Report ($20 state fee) online with the Secretary of State. It is due by the last date of the incorporation anniversary month.
You must file federal and state tax returns. You must also file:
