I am looking for a part-time nanny, two days a week. A friend's nanny has contacted me to say her friend is interested but this person works at a nursery 3 days a week and doesn't want to complicate things from a tax point of view so would be interested if it is a cash-in-hand job. I'm not sure I'm OK about this - I wonder if it leaves me unprotected if we get into difficulties in our employee relationship. Does anyone else pay cash in hand or should i avoid it and try and make it all above board? The whole tax/NI thing seems so complicated, maybe this is an easy solution?
