OK hunt still going on a bit halfhearted because our ideal would be September.
Every single nanny I have contacted (even for Sept. start) has basically said that their NI/tax isn't paid, hence I'm guessing thier employers are happier to pay them what they would be paying gross.
I'm sure you're all paying tax etc and I intend to but I would value comments and some suggestions as to how to find one that does 'want' to pay tax.
