Rachel Reeves has introduced a tax aimed at properties valued over £2 million to ensure wealthier individuals contribute their fair share. The proposed “mansion tax” is anticipated to affect 100,000 to 200,000 homes, resulting in an additional cost of £2,500 for properties exceeding £2 million and £7,500 annually for those valued over £5 million.
This initiative by the Chancellor is projected to generate approximately £400 million for the Treasury each year, with estimates indicating a £0.4 billion increase in 2029/30. Referred to as a “high value council tax surcharge,” Reeves emphasized addressing long-standing wealth inequality within the nation in the current Budget.
Starting in 2028, the High Value Council Tax Surcharge will be implemented in England, targeting properties falling under bands F, G, and H. Reeves clarified that the surcharge would impact fewer than the top 1% of properties, with the funds collected directly benefiting the government, unlike traditional council tax allocations to local councils.
The average Band D council tax in England for the financial year 2025-2026 stands at £2,280. Scotland and Wales have distinct council tax band structures. The Office for Budget Responsibility announced that from April 2028, properties valued above £2 million will face an additional annual charge, ranging from £2,500 to £7,500 based on specific valuation bands.
Initially proposing a £1.5 million threshold affecting 300,000 households, the threshold was raised to £2 million to prevent undue hardship for “asset-rich, cash poor” families. Recent reports by the Institute for Public Policy Research (IPPR) suggest that restructuring property tax could reduce council tax bills for four in five households by 3%, funding essential public services.
In response to the tax reform, Sarah Nankivell, Deputy Director at the Common Wealth think tank, commended the introduction of a mansion tax as a step towards equitable taxation. However, she emphasized the need for more substantial measures, such as aligning capital gains and dividends tax rates with income tax rates, to rectify the existing tax disparities between income sources.
