Tax Credits Appeal Process and Complaints

This guide has information on tax credit appeals and complaints. Find out which tax credit appeal form to use and how to dispute a decision or an overpayment.

TAX CREDITS APPEAL: There are several different options for handling tax credits disputes and disagreement procedures.

If you feel there is a need to pursue action you can choose to:

  1. Complain if you feel the treatment you received was unfair, delayed, or in some way discriminatory.
  2. Disagree with tax credit decision if you believe yours is wrong or their reconsideration was wrong.
  3. Dispute a tax credit overpayment decision if you receive notification to make a repayment.

First Step: Contact the tax credits helpline if you think the Tax Credit Office is the one who made the mistake.

How to Dispute a Tax Credit Overpayment

You must always inform the Tax Credit Office about changes affecting tax credits. But, even when you inform them on time there can still be an overpayment.

As a rule you must repay any overpaid credits. They will continue to reclaim any overpayments while they review your dispute.

Disputing tax credits will have a better outcome if their office made the mistake. Follow the same disputation procedures even if you no longer get tax credits. You can dispute a tax credit overpayment online or by post.

Fill in the government tax credit dispute form TC846 if you feel you should not have to pay back the money.

Tax Credits Dispute Deadlines

There are deadlines for disputing tax credits. You should send your dispute form to them within 3 months of:

Sending in the tax credit dispute form after the 3 month deadline is sometimes allowed. But it is only accepted in exceptional circumstances. An example would be if you got hospitalized for that 3 month period.

A similar process applies to those who request a mandatory reconsideration. In this case, send in the tax credit dispute form within 3 months of getting the reconsideration decision.

Disagree With Tax Credit Decision

The Tax Credit Office should be your first contact if you think something is wrong with your tax credits. They will check your award notice and in some cases they can change it to fix the error.

What happens if they cannot change it or you still feel there is an error? Mandatory reconsideration may be an option in some cases. Fill in the tax credit appeal form WTC/AP and mail it to their office within 30 days of getting your award notice.

What should you do if you still disagree with their result? You can appeal to the Social Security and Child Support Tribunal if you live in England, Wales, or Scotland.

Note: The tax credits appeal process is different in Northern Ireland. Use the Appeals Service Northern Ireland.

How to Proceed with Tax Credits Complaints

The kind of things people complain about include unreasonable delays or the way they got treated. You can choose to write to the Tax Credit Office or call them. Note that telephoning about tax credit complaints usually gets dealt with quicker.

If the result proves to be a mistake made by the Tax Credit Office you may be able to claim costs for phone calls or postage.
