Tax Structure Overview

As a consulting LLC in Colorado, your tax structure depends on your election. By default, you're taxed as a sole proprietorship (single-member LLC) or partnership (multi-member LLC), with profits passed through to your personal income. Electing S-Corp status can lead to self-employment tax savings, but requires careful planning. For more details, see our guide on setting up your Colorado LLC. Colorado's flat income tax simplifies state-level compliance. Lovie can help you determine the optimal tax structure and manage ongoing compliance.
