Tax credits: tell HMRC if you can't repay a tax credit overpayment (TC1133)

Use the online form if you’ve been overpaid tax credits and want to reduce how much you’re paying back through your tax credits payments.


Tell HMRC online (sign in using Government Gateway)


Use the online form service to tell HMRC if:

  • you’re receiving tax credits
  • you’ve been asked to repay an overpayment of tax credits
  • repaying it will make it difficult for you to pay your essential living expenses (for example, utility bills or rent)

It will take you longer to pay off the overpayment if HMRC agrees to reduce the amount you repay every month.

To use the online service, you need a Government Gateway user ID and password. If you do not have a user ID, you can create one when you complete the form.

Then give the following information for you and your partner (if you have one):

  • details of all your household costs and expenses
  • a reason that the repayment will cause you financial hardship
  • details of your income from all sources including:
    • employment
    • self-employment
    • benefits
    • pensions

After you’ve submitted your application you’ll get a reference number that you can use to track the progress of your form.

Email HMRC to ask for this form in Welsh (Cymraeg).

What to do if you’re no longer receiving tax credits

Phone the Tax Credits Payments Helpline if you’re no longer receiving tax credits and want to reduce the amount of your tax credits overpayment due to financial hardship.

Have your tax credit reference number with you when you call.
