You have to repay any tax credits you’re not entitled to. Your future tax credits could go down or stop if you don’t.
The Tax Credit Office can also collect the money you owe from your savings and pension - or take you to court.
Overpayments usually happen if you:
- don’t report a change in your circumstances
- make a mistake on your claim form
- don’t renew your tax credits on time
The Tax Credit Office will tell you what you owe and how to repay the money.
