Is Your Council Tax Bill Wrong? Here's What to Do

Don’t overpay. Check your bill for these common errors.

Receiving your annual Council Tax bill is never fun, but it’s even worse if you suspect the amount is wrong. The good news is that mistakes happen, and they can be fixed. You might even be owed a refund backdated for years.

If something looks off, here are the most common reasons why and the steps you need to take.

Common Reasons Your Bill Might Be Incorrect

• Missing Discounts: The most frequent error is a missing Single Person Discount. If you are the only adult (over 18) living in the property, you are entitled to a 25% reduction. Other disregarded residents include full-time students and some apprentices.
• Wrong Band: Your home's Council Tax band is based on its value back in 1991. If your property is in a higher band than similar homes on your street, it may have been incorrectly valued decades ago.
• Incorrect Details: The bill may be addressed to the wrong person (for example, a previous tenant) or it might not reflect that the property is currently empty or exempt.
• Exemptions Not Applied: Some properties are entirely exempt from Council Tax, such as those occupied only by students, people with severe mental impairment, or properties that are legally repossessed.

How to Challenge Your Bill

Step 1: Contact Your Local Council

If the issue is a missing discount (like the single person discount), the bill is in the wrong name, or you believe an exemption should apply, you need to contact your local authority directly.

• Write to them explaining why you believe the bill is incorrect.
• Your council has two months to respond.
• Important: You must continue paying your current bill while waiting for their decision.

If the council agrees that you were overcharged, they will issue a revised bill and refund the difference.

Step 2: Contact the Valuation Office Agency (VOA)

Your local council does not set the Council Tax bands — the Valuation Office Agency (VOA) does.

You can check your band and compare it with neighbouring properties online at GOV.UK.

If you believe your band is incorrect (for example, if similar homes nearby were sold for less around 1991), you can formally challenge it through the VOA website.

Warning: Be careful. Requesting a reassessment could result in your band increasing as well as decreasing.

Don't Ignore It

If you believe you have been overpaying for years — for example due to a missed single person discount — you may be able to request the claim to be backdated.

While there is no automatic guarantee, many councils will backdate claims if you can provide a reasonable explanation for why the discount was not claimed earlier.
