Refers to the High Value Council Tax Surcharge (England) announced in November 2025 with a £2m threshold.
- YES if the Budget sets the entry threshold below £2m.
- The Times reported on 18 Sep 2026 that £1.5m was under discussion.
- 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.
