Will the United Kingdom agree to or announce an increase in the High Value Council Tax Surcharge or a reduction in its £2 million entry threshold before Dec 1, 2026?

If the United Kingdom agrees to or announces an increase in the High Value Council Tax Surcharge or a reduction in its £2 million entry threshold before Dec 1, 2026, then the market resolves to Yes. This market is not mutually exclusive and multiple markets may resolve to Yes. No market resolves on whether a measure is called a "wealth tax." Each market names one specific measure and resolves only on that measure, whatever it is named. A measure set out in the Chancellor's Budget statement or in the Budget documents published by HM Treasury qualifies, and it need not be legislated or in force before Dec 1, 2026. Measures announced by the Scottish or Welsh governments or the Northern Ireland Executive do NOT count. An announcement qualifies if it involves any of the following: Formal commitment by the head of state/government with constitutional authority Official statements by authorized ministers Official press releases Formal declarations during government proceedings The following do NOT qualify: Preliminary discussions Conditional agreements contingent on circumstances Opposition party statements Leaked documents Think-tank recommendations General aspirations without specific commitment Draft legislation without approval Retraction of previously announced commitments Each market resolves on any announcement meeting its description, with no minimum size: Capital Gains Tax Rise: an increase in any main rate of capital gains tax, even if another main rate is reduced Mansion Tax Increase: an increase in the charges of the High Value Council Tax Surcharge, or a reduction in its entry threshold Inheritance Tax Rise: an increase in any rate of inheritance tax, or a revenue-raising restriction of a relief or exemption Annual Wealth Tax: a new annual tax on total net wealth above a threshold. A one-off levy or a tax on a single asset class does NOT qualify Council Tax Replacement: replacing council tax or stamp duty land tax with an annual property or land value tax
