2. Dispute form TC846

You can ask the Tax Credit Office to reconsider an overpayment decision if you think they made a mistake or gave you incorrect advice.

You can also do this if you’re no longer getting tax credits.

To do this, fill in and send dispute form TC846 to:

Overpayments Dispute Team
Tax Credit Office
HM Revenue and Customs
Preston
PR1 4AT

The Tax Credit Office will continue to reclaim overpayments while they review your dispute.

Deadlines

Send your dispute form within 3 months of the date (the ‘decision date’ on Annual Review notices) on the first letter, statement or notice you received telling you that you’ve been overpaid.

You can only send it after the deadline in exceptional circumstances, eg you were in hospital for the 3 months.

If you’ve appealed against an earlier decision on your claim or you’ve requested a ‘mandatory reconsideration’, you need to send your dispute form within 3 months of getting a decision.

What happens next

You’ll get a letter telling you:

  • if you have to repay the tax credits
  • how much you have to repay
  • the reasons for the decision

If you don’t agree with the decision

You can:

  • send the Tax Credit Office new information
  • ask them to review the information you sent

You’ll need to do this within 30 days of getting your dispute decision letter unless there are exceptional circumstances, eg you were in hospital.

You can only ask for the decision to be reviewed once.

The Tax Credit Office will continue to reclaim overpayments while they review your information.

You can contact an organisation like Citizens Advice if you haven’t got any new information and you’re still unhappy.
