Rachel Reeves is said to be considering the introduction of a new council tax surcharge on properties valued at over £2 million as part of her upcoming Budget. This levy, often referred to as a “mansion tax,” is expected to affect more than 100,000 of the most expensive homes.
Initially, there were reports that the Chancellor was aiming for a threshold of £1.5 million, which would have impacted around 300,000 households. However, it is now believed that the threshold has been raised to £2 million to prevent putting undue financial strain on families considered “asset-rich, cash poor.”
In England, council tax is categorized into bands according to property values from April 1991. The Chancellor is reportedly planning to reassess the most expensive Band F, G, and H homes, affecting approximately 2.4 million properties to determine eligibility for the surcharge.
According to The Times, individuals may have the option to defer payment of the tax until they sell their property or pass away. The Treasury has refrained from commenting on any specific details regarding the Budget proposals.
The average council tax for a Band D property in England for the financial year 2025-2026 stands at £2,280. Scotland and Wales have their own distinct council tax banding systems.
Currently, the government is seeking feedback on a proposal to extend council tax payment periods from ten to twelve months. While households can still opt for the traditional ten-month payment plan, the consultation also considers slowing down the debt recovery process for missed payments.
Residents are encouraged to inquire with their local council about potential council tax discounts they may be eligible for. Additionally, those on benefits or with low incomes should explore Council Tax Support or Reduction schemes offered by their local authorities for possible bill reductions.
Individuals are advised to review their council tax banding to ensure it is accurate. Challenging an overly high band could result in refunds and lower future bills, but caution is advised as contesting a band that is too low may lead to increased future payments.
