I currently nanny part time for two families. One family will be paying me via nanny tax, I work two days a week for them. The other family employ me for one afternoon a week currently (will go up to two days by next march in half-day increments as MB's work load increases) and they will be paying me my net and sorting out the tax themselves and paying it quarterly.
There is a decently paid shift-work based job of 14 hours a week I could go for which will allow me to earn a bit extra to top me up until my second job reaches it's full hours but I am not sure how this will affect my tax? They'd pay by whatever PAYE method they use but will I get taxed substantially as it's a third job or is tax amount income based?
And also, would I be taxed normal rate for my second nannying position? I assume so and my employer is keeping back that amount for tax purposes... (It's £10 gross and she gives me £8 net which sounded right to us both?)
