Budget 2025: Reported tax changes and what they mean for you

18 November 2025

As the UK Chancellor prepares to deliver the Autumn Budget on 26 November 2025, speculation is mounting about measures to address a significant fiscal gap. While headline tax rates may remain unchanged, there are plenty of rumours about reforms and targeted changes that could impact wealth planning, property transactions, and business strategy.

Inheritance Tax – Lifetime Gifting Limits and Extended Rules

Reported changes

  • A lifetime gifting cap.
  • Extension of the seven-year rule to ten years.

Impact

Estate planning strategies may need urgent review to ensure compliance and tax efficiency.

Capital Gains Tax

Reported changes

  • The government may align CGT rates with income tax, potentially increasing rates to 24% or higher.
  • There is talk that there might be a removal of CGT uplift on death.

Impact

Disposal of assets could become significantly more expensive, making timing and structuring critical.

Property Taxes Mansion Tax and reform of SDLT

Reported changes

  • Replacing Stamp Duty Land Tax with a seller-based property tax on homes over £500,000.
  • Introduction of a ‘mansion tax’ for properties above £2 million.

Impact

Higher-value property owners should prepare for increased costs and consider restructuring options.

Income Tax – Frozen Thresholds and Rate Adjustments

Reported changes

  • Continued freeze on income tax thresholds until 2030.

Impact

A stealth tax on earnings, impacting both individuals and businesses.

Exit tax

Reported changes

  • There is talk of a 20% “settling-up charge” on unrealised gains on assets when individuals cease UK tax residency.

Impact

The proposed exit tax could significantly increase upfront costs for individuals leaving the UK, potentially accelerating relocations.
