Request (do not demand, be polite) a full explanation as to why they think you owe this amount of money.
The explantion takes about 4 to 6 weeks to arrive. If anybody telphones/visits in the meantime tell them you are waiting for an explanation.
The explanation will then tell you exactly why you owe this money. If you then dispute the explanation telephone 0845 300 3900 and ask for form TC846 Tax Credit dispute form, on receipt complete and return usually you have 7 days to return this form. Then wait. You will have to explain fully why you dispute the explanation.
One major cause of Tax Credit overpayments is that people do not complete the renewal paperwork on time. If the renewal process has not been completed on time (by 31 July following the tax year in question) the tax credit office have the right to cancel the existing claim, and then claim back monies paid out the previous year or the year to which the renewal paperwork is for and payments made on the current in payment claim.
It is VITAL that the renewal process is completed.
