I only started claiming a few years ago when my income dropped as I was on maternity leave. I am now paying back one overpayment of 3k at £200 a month and currently disputing another overpayment of 6k. The amount of financial and emotional stress the situation is causing makes me wish I never claimed in the first place and tried to manage without. I have done a lot of research on TC overpayments and it seems that it is so common, surely this just goes to show that the system is not working!!!
