By default, a single-member LLC is taxed as a sole proprietorship, and a multi-member LLC as a partnership. You can elect to have your LLC taxed as an S-Corp or C-Corp for potential tax advantages. S-Corp election can help reduce self-employment taxes. We cover this in depth in our resource on starting a business in Colorado. Colorado has a flat income tax rate, simplifying state tax calculations. Lovie can help you determine the optimal tax structure for your Prompt Engineer LLC.
