What is Council Tax Reduction?
Council Tax Reduction is help for people on a low income to pay their Council Tax. In England it is often called Council Tax Support, and each council runs its own scheme, so the rules and amounts differ from one area to another. Wales and Scotland have their own versions.
Your council works out your reduction from your income, savings, household and circumstances. If any of that is wrong, so is the decision.
Common reasons for a wrong decision
- Your income was counted incorrectly, including benefits that should not have counted.
- Someone was treated as part of your household, or as a non-dependant, when they should not have been.
- Your savings or capital were over-estimated.
- A change in your circumstances was not applied, or applied from the wrong date.
- Your claim was not backdated even though you had good reason to claim late.
- The council is asking you to repay an overpayment you believe is wrong.
What your letter should include
- Your name, address, Council Tax account number and the date on the decision notice.
- A clear statement that you disagree and want the decision looked at again.
- Exactly what you think is wrong, with the correct figures or facts.
- The outcome you want, such as a recalculation, backdating to a particular date, or cancelling an overpayment.
- Copies of evidence: payslips, benefit award letters, bank statements, tenancy details.
Steps and deadlines
Keep paying what you are told you owe while you challenge, unless the council agrees otherwise, so you do not fall into arrears on a bill that may later be reduced.
- Check your decision notice. It explains how to ask for a review and how long you have.
- Write to the council with your reasons and evidence. Keep a copy and proof of posting.
- The council should reply in writing. If it changes the decision, check the new figures.
- If the council refuses to change its decision, or does not reply within two months, you can appeal to the Valuation Tribunal.
Wales and Scotland
In Wales the appeal body is the Valuation Tribunal for Wales. In Scotland, reviews go to the council and then to the Council Tax Reduction Review Panel. The details differ, so rely on your decision notice for the exact route.
Frequently asked questions
How do I appeal a Council Tax Reduction decision?
Write to your council asking it to review the decision and explain why it is wrong. If it does not change its mind, or does not reply within two months, you can appeal to the Valuation Tribunal.
How long do I have to challenge the decision?
Your decision notice sets out the time limit. Act as soon as you can, and ask for any late request to be accepted if you have good reason.
Can my reduction be backdated?
Often it can, if you have good reason for claiming late, such as illness. Councils decide this case by case, so explain your reasons clearly.
Should I carry on paying my Council Tax?
Yes, pay what you are asked to pay unless the council agrees in writing to hold it. Challenging a decision does not automatically pause the bill.
Is this the same as challenging my Council Tax band?
No. A band dispute is about the value of your home. Council Tax Reduction is about help with the bill based on your income and circumstances.
