How to repay your tax credits

The Tax Credit Office will write to tell you what you owe and how to repay.

How you repay depends on whether you still get tax credits, Universal Credit or neither.

Call the helpline if you:

  • think the Tax Credit Office made a mistake
  • already have a repayment plan but you get another letter - you may need to set up a new plan

If you still get tax credits

HMRC will automatically reduce your future tax credit payments until you’ve paid back the money you owe.

The amount they’ll reduce your tax credit payments by usually depends on how much you currently get and your household income.

Household income Reduction
£20,000 or less and you get maximum tax credits 10%
£20,000 or less and you get less than the maximum tax credits 25%
More than £20,000 50%

If you only get the family element of Child Tax Credit, your payments will be reduced by 100% whatever your income is.

If you’ve moved to Universal Credit

Your future payments will be reduced until you’ve paid back the money you owe.

If you do not get tax credits or Universal Credit

HMRC will send you a ‘notice to pay’ which you should pay within 30 days.

It’s your responsibility to make sure payments reach HMRC on time. Check your bank’s transaction limits and processing times.

If you do not pay in time, the money you owe will be recovered from you in another way.

Call the helpline if you want to make extra payments to clear the debt more quickly.

There are several ways to repay.
