I have been told that nanny isn't allowed to be self-employed as she can't choose her working hours or can't employ people, but of course there are always exceptions (e.g if she works for more than 2 families - but in this case she needs to register as a childminder not nanny)juliantenniscoach wrote:@mirkaj80. In theory a nanny could become a sole trader couldn't they? (if they wanted to). HMRC seems to give conflicting advice on who and who cannot be self employed. Best wishes.
