1. Disagree with a tax credits decision

You can ask for your tax credits decision to be looked at again if you think it’s wrong.

Call the Tax Credit helpline first. They can check your award and may be able to change it if it’s wrong.

If you’re still unhappy you can make a formal request to have the decision looked at again. The way you do this depends on whether the decision was made before or after 6 April 2014.

There’s a different form if you want to dispute a tax credit overpayment.

Decisions made before 6 April 2014

Check the date on your decision letter - if it’s before 6 April 2014, complete the appeal form or write to the Tax Credit Office.

HM Revenue and Customs (HMRC) will check the decision, explain it to you and change it if it’s wrong.

Decisions made on or after 6 April 2014

If the date on your decision letter is on or after 6 April 2014, you might be able to make a formal request to have the decision looked at again (sometimes called a ‘mandatory reconsideration’).

Your decision letter will tell you if you can ask for a mandatory reconsideration.

Use form WTC/AP to ask for a mandatory reconsideration. Send the form to the Tax Credit Office.

You must request a mandatory reconsideration within 30 days of the date on your decision letter.

The Tax Credit Office might accept your request if you miss the deadline, but you’ll have to explain why it’s late.

If you disagree with the decision

You can appeal to the Social Security and Child Support Tribunal, or the Appeals Service if you’re in Northern Ireland.
