Our nanny works for us 3 days a week. She's looking for another job, for one or two days a week. It's just occurred to me that I don't know what the implications of this are for what we pay her - obviously at the moment we benefit from her personal allowance, and her 10% band.
If she gets another job, would we share her tax allowance with the other family? It would be complicated - we do use a nanny tax service but it's very much no frills. Or do we, as her first and largest employer, keep all of that and the other family will pay tax on her salary at 22%?
I know this in theory isn't our problem as we pay her a gross salary, but though her salary in her contract is stated gross, she thinks in net terms, and we started with the net salary and worked it out in gross terms when we recruited her, so she definitely doesn't see what we pay her as a gross wage which she pays tax on - she sees it as a net wage which we top up with tax. That may not make a difference, but I'm feeling too stupid and addled after a long day at work to work it out for myself...
