As of 22 October 2026, KPMG UK has published its analysis of tax policy statements made during the main political party conferences in autumn 2026. This review provides critical insights into the tax priorities of the governing and opposition parties ahead of the upcoming Autumn Budget. Party conference season traditionally signals emerging fiscal themes, with announcements often foreshadowing legislative changes or political positioning on key tax issues such as corporate tax rates, capital gains, wealth taxes, and environmental levies. The KPMG analysis synthesises speeches, fringe event discussions, and policy papers to identify areas of consensus and divergence.
Key Takeaways
- Corporate Tax Roadmap Clarity: The governing party reaffirmed commitment to the current corporate tax rate but hinted at targeted reliefs for green investment and R&D, while opposition parties proposed rate increases paired with expanded investment allowances.
- Wealth and Capital Gains Focus: Multiple parties signaled intent to review capital gains tax alignment with income tax rates and explore annual wealth tax mechanisms, creating planning uncertainty for high-net-worth individuals and family businesses.
- Green Taxation Expansion: Cross-party support exists for extending the UK Carbon Border Adjustment Mechanism (CBAM) and enhancing plastic packaging taxes, indicating a robust regulatory trajectory for environmental levies regardless of election outcome.
