Does that Council Tax bill on your desk feel… wrong?..

Perhaps you’re a business owner with an instinct that something isn’t quite right with the figures you’ve been told. Or maybe you’re a homeowner left feeling puzzled and confused after a shockingly high council tax bill or a letter from a bailiff. Many people, even those competent in other fields, find themselves in difficulty when faced with these kinds of problems owing to the complex nature of the council tax system.

If so, you are not alone. The situation of being overcharged on council tax or the fear of a bailiff knocking at the door are common, and often this anxiety is compounded by the Council. You supply all the information they ask for yet receive no sensible or reasoned decision, or even see the Council doing the opposite of what they said they would do, leaving you in a state of confusion and bafflement.

So what’s the biggest mistake that people make in this situation? It’s automatically relying on what the Council tells you over the telephone, or even what they may put in writing, and assuming it must be true. An official may say one thing on the phone and then send you a bill that says the complete opposite. Trusting unverified information without checking it or not getting proper advice is one of the most common reasons people find themselves getting deeper in trouble and in debt.

This guide is designed to change that. In the following sections, we will walk you through the confusion, demystify the process, and give you the clear, actionable steps you need to take back control and challenge mistakes and errors by the Council. It’s time to move from feeling powerless to feeling empowered.

 Are You Being Overcharged? The 5 Most Common Council Tax Problems

Many people feel something is wrong with their bill but can't pinpoint the exact issue. Based on 35 years of experience, here are the most common problems that lead to people being overcharged.

1. Large Retrospective Bills: This is one of the most frequent and shocking issues clients face. A council may issue a bill purporting to be for a period of two, three, four, or even more years in the past. This often happens following a bereavement where rules about premiums or exemptions on  empty properties or second homes are misapplied, or with second properties where liability has been miscalculated over time. In other cases, the Council  has acted on erroneous assumptions or failed to upload. In some cases its automated systems may  simply be  creating a bill which has the effect of  covering up their own errors or those contained in some other record. 
2. Incorrect Property Banding (Valuation Errors): The band your property is in dictates the base rate of your tax, but the Valuation Office Agency (VOA) can make mistakes. A common issue, particularly for landlords of Houses in Multiple Occupation (HMOs), is the "disaggregation" of their properties, where individual en-suite bedrooms are incorrectly treated as separate dwellings, each attracting its own bill.
3. Liability Disputes (Being Charged When You Shouldn't Be): A frequent problem is a dispute over who is legally responsible for paying the tax. This is a regular issue for landlords who have multiple tenants. The council may hold the landlord liable when it should be the tenants, or vice versa, due to a misinterpretation of Section 6 of the Local Government Finance Act 1992.
4. Missed Discounts, Exemptions, and Reductions: The system contains numerous ways to reduce your bill, but they are often poorly publicised. Many find they are eligible for discounts or exemptions they were never properly advised on by their local authority. This includes the powerful discretionary reduction under Section 13A of the Local Government Finance Act 1992, often described as one of the system's "best kept secrets". Discretionary reductions can be obtained even when the council (or someone junior in the Council) keeps telling you there is nothing they can do. Often a Council will not tell you about this right or they bury this fact in a long and detailed local reduction policy. Importantly, a section 13A reduction can be applied for in the event you are facing serious financial hardship.
5. Historic Council Tax Bills: Similar to retrospective bills, these are demands created by the council for a period far in the past. These require a specialist response, as the evidence and regulations from that specific time need to be correctly applied. These type of ‘historic liabilities’ can arise where another government agency such as the DWP or another branch of the Council itself - such as the planning department - share old records or data which contain errors. In cases like this you need to be prepared to appeal but also be prepared to go and raise a challenge in the magistrates’ court that Council did not send a bill as soon as reasonably practical (known as the ‘late billing defence’) should the Council try and start recovery proceedings against you. 

 Your Step-by-Step Guide: How to Appeal Your Council Tax

Challenging a Council Tax decision involves a formal statutory appeal process. Here is the basic procedure.

Step 1: Write an Initial Appeal Letter 

The first formal step is to write a letter to your local Council (the "billing authority") outlining your case. This is a critical document that sets the stage for your entire appeal.

The 3 Essential Elements of an Effective Appeal Letter: To make your letter legally effective, it must contain three crucial pieces of information:

1. Your Details: The account number and the full address of the property in question.
2. The Wrongful Decision: You must clearly state the decision you are appealing against, what you believe is wrong with it (e.g., the calculation is wrong, an exemption has not been granted), and what you want the council to do.
3. Be prepared to take your case as an appeal to the Valuation Tribunal for England or the Tribunal for Wales. These are free specialist tribunals which you can take your case to if you cannot resolve the problem with the Council. Taking it there turns your issue from what may get treated by the Council as  a complaint or  objection into a formal, legal appeal that the Council is required to take seriously otherwise they become involved in statutory proceedings. Invoking this right ensures that even if the Council ignores you, there is going to be an independent review of your problem with a judicial ruling at the end of it.
   

Once you write this letter the Council has 8 weeks to resolve your case or face an appeal to the Valuation Tribunal.

Step 2: Gathering Evidence for a Banding Challenge

If you are challenging your property's valuation band, you will need evidence. This is more of an art than a science, as the valuation is a theoretical value of what the property was worth on 1st April 1991. The best evidence you can get is of council tax valuations for properties that are as close as possible in every factor and condition to your own home. Finding a matching property with a lower band is a powerful piece of evidence.

Step 3: Appealing to the Valuation Tribunal 

As mentioned, if the council does not resolve your issue within 8 weeks, you have a further right of appeal to an independent body, the Valuation Tribunal. 

Here you get a chance to present your documents and your side of the situation. This is a formal legal process that requires you to lodge information in writing with the Tribunal and make your case based on fact and law. You can use a wide range of evidence including: witness statements, documents and official records, photographs and even videos. 

You can also raise previous final judgments made by the Valuation Tribunal on the same issue. These can be obtained from the Valuation Tribunal Service website, though they don’t list all of them and tend mostly to list those appeal judgments where the Council was successful, not the taxpayer. Look for those appeals which are recorded as ‘upheld’ . But don’t let that put you off since many cases get settled by negotiation for the taxpayer,  once you start an Valuation Tribunal appeal. These means you may succeed in your appeal and full hearing not need to take place.

 Urgent Help: What to Do If You've Received a Summons or a Bailiff Visit

Receiving a court summons or a notice from an enforcement agent (bailiff) is a major cause of fear and anxiety.

If You Receive a Summons: A summons to the Magistrates' Court is a serious step. However, you can write to the court requesting an adjournment (a pause in proceedings) on the basis you have begun a formal appeal or challenge against the decision of the Council. This may prevent the matter from escalating. Make sure you do  not ignore the summons and be prepared to engage in the process, including being attending the court hearing (even though it is in the magistrates’ court it is a civil process not a criminal one).You can also ask for an adjournment in order to have the opportunity to resolve the case through negotiation with the Council or making an arrangement to pay. In most cases the magistrates’ court will grant an adjournment of the case where you have a genuine basis for appealing, including that you are seeking a discretionary reduction. An adjournment will provide an alternative to get a liability order, providing  an opportunity to settle a case out of court or allow a tribunal appeal and hearing to take place to determine the matter.

If a Bailiff Comes to Your Door: The single most important piece of advice is this: do not ever let the bailiff collecting council tax into the property. You are entitled at law to refuse entry. The best thing is not to open the door at all. If they come inside, they have powers to seize your goods and their charges will go up.
