KalshiRules
YES if the Budget gives England's mayoral authorities a new power to levy a tax, or assigns them a stated share of receipts from a named national tax, with a start date.
- A commitment to consult or negotiate resolves NO.
- The Treasury's 31 July 2026 Budget announcement was titled 'power and money out of Westminster'.
- Resolves YES if the measure is announced in the Chancellor's Budget speech on 28 October 2026 or appears in the Budget documents HM Treasury publishes that day (the Budget document, the policy decisions table, the policy costings, or the Overview of Tax Legislation and Rates).
- A measure announced earlier counts if those documents confirm it.
- A consultation, review or call for evidence alone resolves NO.
