Autumn Budget 2026 - The Changes That Could Affect Your Household Finances

With the Autumn Budget approaching, millions of households will be watching to see whether the Chancellor announces changes to taxes, savings, pensions and property. Here are the key financial issues to keep on your radar.

The Autumn Budget takes place on Wednesday 28 October 2026, and while the Government has yet to reveal its full plans, there are already several confirmed changes that households should be aware of.

There is also speculation around a number of other areas, including Capital Gains Tax, property taxation and Inheritance Tax.

For consumers, however, it is important to separate changes that have already been announced from measures that are simply being discussed.

Some changes are already on the way

The October Budget isn't the only event that could affect household finances. Several measures announced previously are already scheduled to come into force over the next few years.

Electricity bills could become cheaper

One of the more immediate changes is the planned removal of VAT from domestic electricity bills from 1 October 2026.

The measure is expected to reduce household energy costs by around £45 a year, although the actual saving will vary according to electricity usage.

For households already keeping a close eye on their monthly bills, even relatively small reductions could make a difference to annual spending.

Pension savings and Inheritance Tax

People using pensions as part of their long-term financial and estate planning also face an important change.

From 6 April 2027, most unused pension funds are due to be included when calculating an estate for Inheritance Tax purposes.

The change could affect how people approaching retirement think about drawing, retaining or passing on pension wealth.

Anyone who could be affected may want to understand the new rules before making significant financial decisions.

Cash ISA rules are changing

Savers also have a significant change ahead.

From 6 April 2027, the Cash ISA allowance for people under 65 is due to fall from £20,000 to £12,000 a year.

The overall ISA allowance will remain at £20,000, meaning the remaining allowance can still potentially be used through other types of ISA.

The changes are designed to encourage more investment outside cash savings, although the impact will depend on individual circumstances.

Higher-value properties face a new charge

Owners of expensive properties in England should also be aware of the planned High Value Council Tax Surcharge.

The surcharge is due to begin in April 2028 for residential properties worth more than £2 million.

The annual charge is expected to range from £2,500 to £7,000, depending on the value of the property.

What could the Chancellor announce?

While several financial changes are already confirmed, there is much less certainty around what could be announced on Budget Day.

The Government has not published its full Budget plans, so reports about potential tax increases should not be treated as confirmed policy.

Capital Gains Tax remains an area to watch

Capital Gains Tax (CGT) has been the subject of considerable discussion.

One possibility that has been raised is bringing the taxation of capital gains closer to the taxation of earnings.

However, no specific CGT changes have been confirmed for the Autumn Budget.

For investors and people who hold assets outside tax-efficient accounts, any changes announced in October could therefore be worth watching closely.

Could property taxation change?

Property taxes are another area that could attract attention.

Prime Minister Andy Burnham has previously expressed support for the idea of a land value tax, which would be based on the value of land rather than simply the property built on it.

However, the Government has also said there are no immediate plans to abolish either Stamp Duty or Council Tax.

That means homeowners and prospective buyers should distinguish between longer-term policy discussions and measures that have actually been announced.

Inheritance Tax could face further scrutiny

Inheritance Tax has also been discussed as an area for potential reform.

Previous comments have included the possibility of replacing the existing system with a broader levy on estates.

There are currently no detailed proposals confirming such a change in the October Budget, so it remains an area to monitor rather than a confirmed upcoming tax change.

What about Income Tax and National Insurance?

The headline rates of Income Tax, VAT and National Insurance will be closely watched when the Chancellor delivers the Budget.

The Government has indicated that it does not intend to increase the main rates of these taxes.

However, the final position will only become clear once the Budget has been announced.

It's also worth remembering that changes to allowances and thresholds can affect how much people pay even when the headline tax rates remain unchanged.

State Pension: another issue for the future

Retirement planning could also be affected by developments around the State Pension.

The Government has pledged to maintain the State Pension triple lock, under which payments increase by whichever is highest of inflation, average earnings growth or 2.5%.

The State Pension age is also an issue to watch over the longer term.

Under current legislation, the State Pension age is scheduled to rise from 67 to 68 from 2044.

However, analysis from the Office for Budget Responsibility has suggested that the increase could potentially happen earlier, between 2037 and 2039.

This is not the same as an announced change to the State Pension age, but it illustrates why people planning for retirement need to keep an eye on future policy developments.

Why the Government's finances matter

Behind many of the Budget decisions is the state of the UK's public finances.

UK borrowing costs reached their highest level since the 2008 financial crisis in early September, according to Fidelity's analysis.

When Government borrowing becomes more expensive, more money can be required to service existing debt. That can affect the amount of money available for new spending commitments or tax reductions.

Defence spending is another significant consideration, with the Government committed to increasing defence spending to 3.5% of GDP by 2035.

What does this mean for households?

For most people, the biggest takeaway is that not everything being discussed ahead of the Budget will necessarily become law.

There are already confirmed changes that could affect:

For consumers, the best approach is to distinguish between confirmed measures, possible reforms and media speculation.

The Autumn Budget could have implications far beyond tax bills.

Changes to household finances can affect how much people have available for mortgages, insurance, savings, energy, investments and other everyday expenses.

The Chancellor's statement on 28 October should provide a clearer picture of what is changing and when.

Until then, households should be cautious about making major financial decisions based solely on speculation.
