LLCs in Connecticut offer flexibility in tax structure. By default, a single-member LLC is treated as a disregarded entity for tax purposes, meaning income is reported on your personal income tax return (Form 1040). Multi-member LLCs are taxed as partnerships. Our resource on [the Connecticut LLC filing process](https://www.lovie.co/formation/resources/llc-formation/agency-connecticut) breaks this down further. However, you can elect to have your LLC taxed as an S-Corp or C-Corp for potential tax advantages. Connecticut also imposes a Business Entity Tax (BET) on LLCs.
