You might be overpaid tax credits if:
- there’s a change in your circumstances - even if you report the change on time
- you or the Tax Credit Office make a mistake
- you do not renew your tax credits on time
The Tax Credit Office will write to tell you what you owe and how to repay the money. If you think they made a mistake, call the helpline.
If you still get tax credits or are now getting Universal Credit, the money you owe will usually be taken from your future payments.
If you do not get tax credits, Universal Credit or another benefit, you’ll have to pay the money you owe to HM Revenue and Customs (HMRC) directly.
