4

Draft and Sign a Partnership Agreement

Create a written Partnership Agreement outlining each partner's contributions, profit and loss sharing, roles, decision-making authority, and dissolution procedures. While not legally required to be filed with the state, this document is essential to defining the partnership's operations.

2-5 hours

What's Next After Filing

Once your Partnership is officially formed, you'll want to complete these important steps:

  • File Formation Documents with the StateFor Limited Partnerships, file a Certificate of Limited Partnership with the Connecticut Secretary of the State online or by mail, along with the $120 filing fee. General Partnerships may optionally file a Trade Name Certificate with the local town clerk if operating under a fictitious name.
  • Obtain an EIN and Open a Business Bank AccountApply for a Federal Employer Identification Number (EIN) from the IRS at no cost, which is required for tax purposes and opening a business bank account. Keeping finances separate from personal accounts is critical for accurate record-keeping.
  • Register for Connecticut State Taxes and LicensesRegister with the Connecticut Department of Revenue Services for applicable state taxes, including sales tax or withholding tax if you have employees. Obtain any required local or professional business licenses or permits applicable to your industry.

Advantages

  • Simple and inexpensive to form, especially General Partnerships which require no state registration in Connecticut
  • Pass-through taxation avoids double taxation, with profits and losses reported directly on partners' personal tax returns
  • Flexible management structure with no requirement for a board of directors or formal officer roles
  • Minimal ongoing compliance requirements and lower administrative burden compared to corporations

Considerations

  • General partners face unlimited personal liability for business debts, obligations, and the actions of other partners
  • Difficulty raising capital compared to corporations, as partnerships cannot issue stock
  • Partnership dissolves upon the death, withdrawal, or bankruptcy of a general partner unless the agreement provides otherwise
  • Limited partners in an LP cannot participate in management without risking loss of their liability protection

Annual Obligations

Annual Report Fee:$20
Report Due:March 31
Connecticut Limited Partnerships must file an Annual Report with the Secretary of the State by March 31 each year, with a $20 filing fee. General Partnerships are not required to file an annual report with the state. LLPs registered in Connecticut must also file an annual report. Partners must report their share of partnership income on their individual Connecticut income tax returns, as partnerships are pass-through entities for tax purposes.
