Overpayments – what they are, how they happen and what happens next
How you'll be asked to repay - either by reducing your tax credit payments, or making a direct payment
What if you can't pay back an overpayment - when can repayments be reduced or written off?
What to do if you think the Tax Credit Office made a mistake
Who's responsible for a joint overpayment and what you need to do if you or your ex-partner can't or won't repay the money
Make sure overpayments and underpayments don't happen - check your tax credits award notice and report any changes
