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 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.
Single-member LLCs pay self-employment tax (15.3%) plus income tax on all net profits, reported on Schedule C of the owner's personal tax return.
