By default, your marketing LLC will be taxed as a sole proprietorship (if you're the single member) or partnership (if multi-member). You can also elect to have your LLC taxed as an S-Corp or C-Corp. Each structure has different tax implications, so choose wisely. We cover this in depth in our resource on forming an LLC in Colorado.
