I've received a letter from tax credits saying I need to pay £1800 penalty for negligently claiming tax credits for the tax year 12/13.
I had a letter from compliance just before the renewal process in April asking for child care costs, bank statements and work contracts. It emerged that they overpaid me for childcare and the 30hours element (my hours reduced to 25 during the tax year). I completely forgot to change them and admitted fault and have been paying the overpayment back through reduced tax credits.
The penalty notice is dated 27th November but I live with my sister and she accidentally took it into her room so I only read it today.
What can I do to appeal? I'm so scared- I don't have that kind of money to pay out. I'm a single parent of 2. The deadline for the penalty was Friday so I'm probably already incurring interest!
Thanks in advance
