Hello all, My other half has been overpaid her wages over a year. The amount per month wasn't much which is why it went unnoticed until we received a letter saying it would be reclaimed. No problem with the money being taken back, it was approximately £30 extra a month and as her wage can vary she didn't notice it. The amount owed is close to £500, her employers payroll department were quite demanding about how and when the amount should be repaid. She's outlined a payment plan to them so the full amount doesn't just disappear as we're heading towards Christmas. They wish to reclaim the full £500 but she would have paid tax and NI on that amount, is that right? I know some of you have been in a similar situation so just looking for advice.
