    • EIN verification letter
    • Amendments to and other filings to the LLC during its lifetime
  5. The Operating Agreement should be created

    • C-Corps are subject to double taxation. The corporation pays taxes on profits, and members pay taxes for distributions. C-Corps may offer low tax rates for retained earnings if profits exceed $250,000 per owner.
  10. Apply for Business Licenses & Permits

    Licenses and permits are required to legally run your business. You can search for your type of business and the location you live in using the Small Business Administration Business License & Permit Look-up Tool. This will allow you to quickly navigate through the many federal, state, local, and international requirements.
