We are about to hopefully hire a lovely nanny part time, 16 hours per week over 4 days. She'll be continuing to work at a preschool a couple of hours a week to earn extra money. Does anyone know how it should work with her tax and specifically her tax free allowance? She will be earning under £6k net per year. Do we get the benefit of this or will her other job where she will already be working but doing less hours than for u? i hope I'm making sense!!
