Tax Structure Overview

Arizona LLCs offer flexibility in tax structure. By default, your LLC will be taxed as a sole proprietorship (if you're a single-member LLC) or a partnership (for multi-member LLCs). However, you can elect to have your LLC taxed as an S-Corp or C-Corp for potential tax advantages. For a deeper dive, see our resource on the Arizona LLC filing process. For most software developers, the S-Corp election is worth considering to minimize self-employment tax.
