As a consulting LLC in Connecticut, your default tax structure is pass-through taxation. Profits are passed through to you as the owner and taxed at your individual income tax rate. You can elect to be taxed as an S-Corp, which may offer self-employment tax savings. We cover this in depth in our resource on [how to register an LLC in Connecticut](https://www.lovie.co/formation/resources/llc-formation/agency-connecticut). Connecticut also imposes a business entity tax on LLCs, regardless of income.
