I have been claiming CTC since last April based on estimated earnings, however, recently my dh got a temporary better paid job - I informed the CTC Office of this yesterday and they said that my payments will obviously stop as I would now go over my estimated earnings and they told me that I would have to pay all the payments made to me back - approximately £2500 - I asked if I could pay in installments and they said that was something I would have to negotiate after they have received the final earnings for this year and there would be a number to ring on the demand letter when I receive it from them. I am very worried - has anyone on mumsnet negotiated a repayment plan with them and if so, can you give me any idea as to how long I will be given to pay the £2500 back (I was hoping to pay around £30/40 per month. Does anyone know if you have to send bank statements, proof of outgoing etc to them and if they are flexible on paying them back? Any advice gratefully received.
