We have just employed a lovely nanny, having advertised at a net wage (as seems to be standard). It has just occurred to me, while setting up the payroll, that although we are employing the nanny for more than half of the week (3 days), the fact that she already has an employer for the other two days means that we will be the 'second' employer, so will presumably end up with a BR tax code rather than 810L.
Presumably this means that we will end up paying a far higher gross salary? I have no idea whether her first job uses up her entire personal allowance (I suspect it does, or fairly close to, assuming she is paid a similar hourly rate to what we offer and works full days, which I am fairly sure she does).
We'll suck this up if we have to, but is there any way of splitting the tax code between employers? Would I need the approval of her current employer to do that? Or would it be something for the nanny to do?
Also, I keep reading about RTI. Am I right in thinking that this will make it much more common for nannies to be employed on a gross salary? I am planning on putting a gross salary on our nanny contract from the beginning, will that prevent any issue there?
Any thoughts much appreciated!
