For a single-member LLC in Connecticut, the default tax structure is pass-through taxation. This means your business profits are taxed at your individual income tax rate. 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](https://www.lovie.co/formation/resources/llc-formation/agency-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. Consulting with a tax professional is highly recommended to determine the optimal tax strategy for your solo founder LLC.
