1. Overpayments

You may have to repay any tax credits you’re not entitled to. Overpayments can happen if:

  • you don’t report a change in your circumstance to the Tax Credit Office
  • you make a mistake on your claim form
  • you don’t renew your tax credits on time

The Tax Credit Office will tell you what you owe and how the money can be repaid.

If you don’t pay, HMRC can change your tax code to collect the money owed. They’ll write explaining how this works. To ask them not to do this and pay another way you must contact them within 30 days of their letter.
