Tax Structure Overview

As an e-commerce LLC in Connecticut, your tax structure depends on your election. By default, you'll be taxed as a pass-through entity, meaning profits are taxed at the individual level. You can also elect to be taxed as an S-Corp or C-Corp, each with distinct tax implications. Connecticut also imposes a business entity tax on LLCs, regardless of federal tax election.
