Council Tax Bands for Expensive Properties: The Mansion Tax Debate
Updated for 2026
Council Tax Bands for Expensive Properties: Where Do We Stand?
Council tax bands for expensive properties have been a source of political debate for well over a decade. Back in 2014, the idea of a “mansion tax” on homes valued at £2 million or more gained significant attention, with cross-party support from both Labour and the Liberal Democrats. The proposal aimed to create fairer council tax contributions by introducing higher bands above the current Band H threshold, which still applies to properties valued at more than £320,000 based on 1991 valuations.
Despite years of discussion, no mansion tax was ever introduced. Instead, the government chose to increase Stamp Duty Land Tax (SDLT) on high-value property purchases. Council tax bands in England remain based on property valuations from 1 April 1991, a system widely criticised as outdated and unfair. Calls for a council tax revaluation continue to grow, but successive governments have avoided what would be a politically difficult process.
Why Council Tax Reform Still Matters in 2026
The debate around taxing expensive properties has not gone away. In 2026, average council tax bills across England have risen again, with many local authorities applying the maximum permitted increase. For households already struggling, these rises add real pressure. The gap between what lower-income families pay relative to their property value and what wealthier homeowners contribute remains a sore point in the system.
Under the current banding structure, someone living in a Band H property worth several million pounds may pay only two to three times more council tax than a household in a modest Band A home. Critics argue this is disproportionate and that a fairer system would see higher-value properties contribute more through additional bands or a proportional charge.
What Happens If You Fall Behind on Council Tax
Regardless of whether you live in a Band A flat or a Band H detached house, falling behind on council tax can have serious consequences. Your council can apply for a council tax liability order through the magistrates’ court, which opens the door to enforcement action including bailiff visits, attachment of earnings orders, and in extreme cases, committal to prison.
If you are worried about paying your council tax in 2026, it is important to act early. Contact your local authority to discuss a repayment plan before enforcement action begins. You may also be entitled to a council tax reduction depending on your circumstances.
