Autumn Budget 2026 Tax Watch: What Could Change on 28 October

Autumn Budget 2026 tax watch – capital gains, inheritance tax, frozen thresholds and property

Chancellor John Healey delivers his first Autumn Budget on 28 October 2026. Prime Minister Andy Burnham has committed to Labour’s manifesto pledge not to raise the main rates of Income Tax, National Insurance or VAT. But with spending pressures high and limited room under the fiscal rules, that does not mean taxpayers are off the hook. Here is what could be on the table, and what you can sensibly do before Budget day.

Why the main tax rates being ruled out doesn’t mean no tax rises

With the three biggest taxes off limits, attention has shifted to other sources of revenue: wealth, investments, property and pensions. Expect plenty of predictions between now and 28 October. Most of them remain speculation, and nothing is confirmed until the Chancellor stands up.

Capital Gains Tax could come under scrutiny

Capital Gains Tax (CGT) is one of the most talked-about areas. Possible options include:

  • raising CGT rates closer to Income Tax rates
  • changing the reliefs and allowances available to investors and business owners

Changes like these would affect anyone selling investments, second homes or a business. The annual CGT exempt amount is already small, so more investors are paying tax on gains made outside tax-efficient wrappers. That makes the timing of disposals, and the use of ISAs and pensions, more important than ever.

Property and wealth in focus

Property tax could also feature, with speculation centring on higher-value homes. The government has denied reports that it plans to replace Council Tax and Stamp Duty with a land value tax in this Budget.

A broader wealth tax has been discussed, but there is no confirmed proposal. Inheritance Tax (IHT) remains one to watch, particularly as most unused pension funds are due to fall within the IHT regime from April 2027.

The quiet impact of frozen thresholds

Tax rises don’t need a headline rate change. Keeping allowances and thresholds frozen while wages and asset values rise gradually pulls more people into tax, or into a higher band. This is known as fiscal drag.

Fiscal drag chart: a £45,000 salary rising 3% a year crosses the frozen £50,270 higher rate threshold by year 5

For 2026/27, the Personal Allowance remains at £12,570 and the higher rate threshold at £50,270 in England, Wales and Northern Ireland. As incomes rise, more people pay more tax even though the rates themselves haven’t changed.

Be prepared, not reactive

Your financial future is too important to be shaped by rumours, headlines or knee-jerk reactions. A better approach is to understand where you stand before the Budget and identify the areas that may need attention.

Whether you are approaching retirement, building your investments, running a business or thinking about your family’s future, now is a good time to review:

  • pension contributions and retirement planning
  • ISA allowances and investment planning
  • Capital Gains Tax on investments or other assets
  • Inheritance Tax, gifting and estate planning
  • business remuneration, dividends and extraction strategies
  • whether your investment strategy still suits current market conditions

Review before the Budget, act after it

You don’t need to predict what the Chancellor will announce. You need to understand your current position and where potential changes could affect you.

By reviewing your circumstances before 28 October, we can identify the areas that may need further thought. Once the measures, and the detail of any legislation, are known, we can assess whether action is right for you. That means less guesswork, fewer rushed decisions, and a plan built around your circumstances rather than the latest headline.
