Official Cost varies
About this service
The body that collects social security contributions. If you work as a micro-entrepreneur, you declare your turnover to Urssaf online every month or every quarter (as you choose) and pay your contributions at the same time; with no turnover, no contributions are due unless you opt to pay minimum contributions to keep social cover. Urssaf also publishes contribution simulators.
