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, the initial award and payments are provisional. The amount of tax credits you are actually entitled to for a tax year is not decided until the award ends and HMRC review your income and circumstances and make their final decision.
This is normally done after the end of the tax year for which tax credits have been given but where the person has claimed universal credit (UC) in the same tax year as they had claimed tax credits, HMRC will usually finalise the tax credit award during the year.
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.
