Choose your business structure and register what applies

Choose the structure that matches your risk, tax, and ownership needs.

Choosing the right structure affects liability, taxes, ownership, and compliance. Many owners consult a CPA or attorney before making a final decision.

  • Sole Proprietorship: simplest setup, owner is personally liable
  • Partnership: shared ownership, terms should be documented
  • LLC: liability protection with flexible management options
  • Corporation: stronger formal structure, common for scaling and investment
