The difference between main profession and secondary profession

Main occupation: if the self-employed activity is your main or only occupation. You are not a student, and you do not also work as an employee. 

Secondary profession: if you are a salaried employee or civil servant in addition to your self-employed activity.


You are self-employed in a secondary occupation if you:

  • still work at least half-time as a salaried employee;
  • performs at least 60% of a full-time schedule as a permanent teacher or 50% as a contractual;
  • enjoy the unemployment with company allowance (early retirement) scheme or receive unemployment benefits; or
  • receives sickness or disability benefits as a salaried employee.
