Urssaf Caisse nationale (formerly Acoss)

This device allows you to declare your activity, your fees and pay your social contributions directly from your personal online space. The Urssaf thus becomes your sole interlocutor.

Once your personal space is created, you declare your activity only once before your first replacement.

When you register, you can choose whether you want to declare your fees at the end of each month or quarter (you cannot change the frequency during the year). 

When the replacement fee return has been entered each month or quarter in the personal space and the amount of contributions paid, no further action is required. A declaration need not be made where no replacement has been made during the month or quarter.
