You'll report your business income and expenses on Schedule C of your personal income tax return (Form 1040). Our resource on how to register an LLC in Connecticut breaks this down further. Alternatively, you can elect to have your LLC taxed as an S-Corp or C-Corp, which may offer tax advantages depending on your specific circumstances.
