Help! My husband and I just realised that we have been paying our nanny her gross salary to her bank account each week, without taking out taxes, and then paying the taxes to HMRC on top of it. We miscommunicated and divided up the work on the actual payment of the nanny and then the communication with Nannytax/HMRC. This has been happening for 18 months. We have always felt like our taxes were incredibly high, but just realised we haven't been deducting the taxes from her pay. We also thought she had been getting her payslips directly from Nannytax, but are now realising that's also not the case. Can we ask for money back from the past 18 months of double paying -- or are we out of luck? We love our nanny but we cannot continue wrongly paying this amount and are worried she will leave once the taxes are properly taken out as well.
