I have just had a letter fall through the door, to tell me a tax credit overpayment from 19 years ago needs paying back.
It's for working tax credits, my ex and I had a claim and then stopped it when we took a year out to move to another country. We thought it was all done and dusted but there was a paperwork mix up that resulted in an large overpayment.
Anyway, I was sure we'd paid it off but this letter arrived today. I've contacted my ex who says he's not received one and if he doesn't he's categorically not going to acknowledge it as it's so long ago.
Is there a cut off period they can ask for it back? I'm already struggling. I can't afford £1k repayment! It's a whole load of stress I don't need at the moment.
