Connecticut LLCs offer flexibility in tax structure. By default, an LLC is taxed as a pass-through entity (sole proprietorship or partnership). However, you can elect to have your LLC taxed as an S-corp or C-corp for potential tax advantages, especially when managing multiple entities. Our resource on [how to register an LLC in Connecticut](https://www.lovie.co/formation/resources/llc-formation/agency-connecticut) breaks this down further. The best option depends on your specific circumstances, requiring careful planning and potentially consultation with a tax advisor.
