What if I have a tax credits overpayment?
Overpayments and underpayments are a normal part of the tax credits system. This is because when you receive a tax credits award it is not final until after the end of the tax year for which it has been given.
We explain how overpayments occur, how to challenge an overpayment and how to pay back an overpayment in our 'tax credits and benefits section'.
You will also find information on what to do if you are finding it difficult to repay an overpayment as well as links to more detailed information.
