Step-by-step procedure

Section actions
  1. 1Compare micro-enterprise, EURL and SASU on three points: taxes, social contributions and personal liability. It's the easiest way to see if change is really worth it.
  2. 2Prepare the statutes of the SASU (status). You can start from a model, but many take a lawyer to avoid mistakes from the start.
  3. 3Place the file on the Single Window. This is the point of entry for formalities, not a simple information page.
  4. 4Once the company is registered, pick up the Kbis and SIRET. Without them, the bank and the customers will still ask you to complete the file.
  5. 5Put the accounts in place right now. In SASU, it is mandatory, even when activity starts slowly.
  6. 6Decide how you will pay: salary, dividends or a mixture of the two. The right choice depends on the level of income, not just the monthly amount.

Common mistakes

Section actions
  • Stay on the microphone while the business model has already changed.
  • To postpone accounting and waste time reconstructing it later.
  • Consolidate pay and dividends as if the tax effect were the same.
  • Presenting micro-enterprise and EI to the real regime as two distinct legal forms: micro-enterprise is a tax and social system of EI.
