Common Mistakes to Avoid

  • Assuming a single, one-time fee covers all federal tax obligations is incorrect, as many are annual or income-based.

  • Ignoring FTC compliance requirements, even if advertising seems minimal, can lead to penalties.
  • Failing to account for self-employment tax if you are a member-managed LLC is a common oversight.
