## About

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
