As I understand it, but can't cite a source, someone transferring to Micro Social from another regime gets the same deal as a new AE; I heard an URSSAF adviser explaining this to someone recently. However the rules are changing (probably with effect from new year) so that anyone converting who is already in same line of business (e.g. cleaner) doesn't get the benefit. This is extended to meaning that even if your partner or child has been working as a cleanr you can't get the free year(s) if you register as an AE cleaner. This may mean that even if you should have got out of paying the Taxe Pro / CFE they might say that you're caught by the rule change.
I'll try to find the official statement on this, but don't hold your breath.
