Autumn Budget 2026: separating what we know from speculation

For investors and families trying to plan ahead, separating meaningful developments from speculation can be difficult. So what do we actually know and what should you be thinking about today?

The debate around how wealth is taxed is not new. But the appointment of Andy Burnham as Prime Minister has brought renewed attention to the subject.

Burnham has previously argued that the UK places too much of the tax burden on work relative to wealth, with property and land taxation featuring in his thinking. He has historically supported reforms to property taxation, including alternatives to transaction-based taxes such as stamp duty.

However, discussing reform is very different from implementing it.

Significant changes to the way property or wealth is taxed could require decisions around valuations, rates, exemptions and transitional arrangements, as well as potentially extensive consultation and implementation work.

John Healey's appointment as Chancellor introduces another unknown. While he has previous Treasury experience, there is currently limited evidence from which to draw conclusions about his approach to wealth or property taxation.

The important distinction, therefore, is between the wider political debate about taxation and confirmed government policy.

CGT is another area likely to attract speculation.

There are complex interactions between taxes on owning, buying and selling assets. For example, the government may want to encourage people to move home, sell assets or make more productive use of capital, while also considering how wealth and investment gains are taxed.

These competing objectives demonstrate why tax policy cannot always be considered in isolation and why trying to anticipate individual measures before they are announced can be difficult.

Until the Chancellor sets out his plans, potential changes to CGT, property taxation or broader wealth taxes remain just that: potential changes.

For now, the answer is relatively simple: focus on what you can control.

Good financial planning should be based on your circumstances, long-term objectives and the rules that exist today, rather than speculation about what might happen tomorrow.

That could mean considering whether you're making appropriate use of existing allowances and reliefs, reviewing your pension and investment arrangements, or thinking about how wealth will eventually pass to the next generation.

It may also be a useful opportunity to ask whether your wider financial plan still reflects what you want to achieve.

Taking advice doesn't necessarily mean making changes before the Budget. In some cases, the most appropriate course of action may be to wait. But understanding your current position and options can leave you better prepared to assess confirmed changes when they arrive.

There will inevitably be considerable noise between now and 28 October. Some speculation may ultimately prove accurate; much of it may not.

Rather than trying to predict individual announcements, we believe investors and families are generally better served by concentrating on robust, long-term financial planning while remaining ready to adapt when the facts change.

Evelyn Partners will be monitoring developments closely and helping clients understand what confirmed announcements could mean for their finances and future plans.
