the law changed about 3 years ago now... (or is it 4?)
it is now illegal for a nanny to be self employed (but eys could be done a few years ago)
the reason is nannies dont meet self employment criteria.... different hours in differnt homes where THEY choose the hours and decide weatehr to work or not etc.
There are very very few exceptions (one being maternity nannies whose contract only last a few weeks at a time, and they too ahve probs if there were to remain over 6 months)
As you have a nanny you have to be her employer and therefore have to pay employers NI contributions as well.
If you dont pay you employers NI contributions, then the government will fine you £3000 is they found out
Im sure this isnt a risk you want to take so if i were you id tell her about your legal obligations as an employer, and how her job does not fit self employment criteria and that from now on you will be passing erh tax and NI on to inlnad rev along with your own wmployers NI contributions...
that is perfectly fair, you are not cheeting her out of any money and you save YOURself the work.
Any nanny agency or nannytax or even the tax office people will tell her the same if she wants to check
