Dissolve a Connecticut LLC or corporation

File with the Connecticut Secretary of the State. Some companies also need a tax sign-off.

The catch

The Secretary of the State charges nothing and asks for no tax proof. Revenue Services still expects final returns, and a corporation may want its AU-797 statement before paying out the last of its cash.

How to close a company in Connecticut

  1. Get the tax sign-off

    Connecticut charges $0 to dissolve an LLC or a corporation.

  2. Wind up the business

    Hold the vote your governing documents and Connecticut law require. Pay or set aside what you owe, in the order your lawyer advises.

  3. File with the Connecticut Secretary of the State

    LLC: BUS-035, No state fee. corporation: BUS-019, No state fee.

  4. Pick how to file
