Am getting a bit worried as have recently had a letter from tax credit people saying we need to renew our income details this April. For the past 6 months we've been getting £360 a month to help with childcare costs of £200 a month. I called the helpline back then and explained the discrepency but they didn't seem that bothered or really give me an answer and said something about working tax credits too. I really didn't think we were entitled to them too. Arghh! Confused by the whole thing, don't understand why they had this figure as we were completely honest with our income, nursery costs etc at the last renewal. Does anyone know if they can demand any overpaid amount back in one go? I Am starting to have sleepless nights thinking they might demand it all back in one go which would be a nightmare. Any experience, advice please??
