If you’re wondering how the changes announced in the Autumn Budget 2025 will affect you, speak to a financial adviser.

Cash ISA reforms

From April 2027, the government aims to restrict the amount people under 65 can save into a cash ISA.

For anyone under 65, this means the annual tax-free limit for cash ISAs will drop from £20,000 to £12,000. You’ll still be able to save £12,000 in cash ISAs, but the remaining £8,000 will need to be used for investment ISAs such as a Stocks and Shares ISA or a Lifetime ISA.

Meanwhile, the overall annual ISA subscription limit of £20,000, and within this the various ISA limits, will be frozen until April 2031. This amounts to:

• £20,000 for Stocks and Shares ISAs.
  
• £4,000 for Lifetime ISAs.
  
• £9,000 for Junior ISAs and Child Trust Funds.

The government is also expected to announce further details in 2026 on a new ISA designed to support first-time buyers, which will replace the current Lifetime ISA.

A cash ISA is a tax-efficient savings account that protects your returns from income tax and capital gains tax, whether you’re saving in cash or investing in the markets.

Importantly, anyone aged 65 and over will still be able to invest their full £20,000 ISA subscription limit in a cash ISA going forward.

Changes to salary sacrifice

From April 2029, any salary or bonus sacrificed as pension contributions above £2,000 a year will be subject to employer and employee National Insurance.

This change means that many employees may no longer benefit from the extra uplift they currently receive if employers pass on their National Insurance savings.

Despite these Budget changes, salary sacrifice remains a tax-efficient way to contribute to your pension.

State Pension increase

The government announced it has no immediate plans to reform the State Pension triple lock. This means the full new State Pension will rise by 4.8% in April 2026 — matching earnings growth and coming in more than 1% above inflation.

Meanwhile, the Autumn Budget 2025 confirmed that pensioners who rely solely on the State Pension will pay no income tax on payments that exceed the £12,570 personal allowance.

Income tax thresholds frozen

The government announced that income tax thresholds in England, Wales and Northern Ireland will remain frozen for an additional three years, until 2031. This freeze applies to both employed workers and the self-employed.

As a result, any pay increase you receive may result in you paying more tax because the tax bands aren’t increasing with earnings. Not only that, but more people are likely to move into higher tax brackets, and many could see their overall tax bills rise over time.

National Living Wage increase

In a welcome boost for low earners, the National Living Wage will increase from April 2026, giving a pay rise to 2.4 million UK workers who fall into this category. This amounts to:

• A 4.1% increase in the National Living Wage to £12.71 per hour for eligible workers aged 21 and over (up from £12.21 per hour).
• Those aged 18 to 20 years will see their rate rise by 8.5% to £10.85 per hour (up from £10 per hour).
• A 6% rise to £8 per hour for under-18s and those on apprenticeship schemes (up from (£7.55 per hour).

Removal of the two-child benefit cap

The Autumn Budget 2025 also delivered sweeping changes to the two-child benefit cap within Universal Credit.

From April 2026, the two-child benefit cap will be lifted, enabling families to receive financial support for more than two children. This is aimed at ensuring more households can access the financial help they need while reducing child poverty.

The benefit cap currently prevents parents from claiming certain benefits for more than two children, but these restrictions will now be scrapped.

Tax increase on dividend income

While the dividend additional rate will remain at 39.35%, the basic and higher rates of tax on dividend income will rise by 2% from April 2026. This amounts to an increase from 8.75% to 10.75% and from 33.75% to 35.75%, respectively.

Even though the additional rate will stay the same, the changes look set to make dividend income outside tax-efficient wrappers more expensive for consumers.

Stamp duty and property taxes

From April 2028, a new high-value property surcharge will be applied to homes worth £2 million or more. For properties valued above £5 million, the annual surcharge will rise to £7,500.

The government also confirmed that existing standard stamp duty and property taxes will continue to apply as usual. However, the government is creating separate tax rates for property income. From April 2027, the property basic rate will be 22%, the property higher rate will be 42% and the property additional rate will be 47%.

What should I do to prepare for the Autumn Budget 2025 changes?

Now the UK Government has released its 2025 Autumn Budget, keeping up with what’s changing – and what isn’t – can help you make confident, well-informed decisions about your financial future.

We’ve highlighted the key information to help you focus on the points that matter most to you.

1. Review your pension pot

Identify how much of your pot is unused or uncrystallised and check how your scheme pays death benefits. Ensure your named beneficiaries still reflect your wishes. This will help you work out how much pension income you’ll need for a comfortable retirement in light of the Budget announcement.

2. Assess your ISA allowances

Now could be a good time to re-evaluate your cash ISAs following the government’s planned changes to the annual cash ISA allowance.

For instance, it could be beneficial to maximise your current ISA allowances before the changes take place in 2027. Similarly, you may want to consider Stocks & Shares ISAs as a viable alternative, especially if you are making long-term retirement plans.

3. Consider your income tax thresholds

You could begin to factor in any threshold freezes into your financial planning, as more of your income may become subject to income tax.

With property income tax due to increase by 2% across all tax bands in April 2027, landlords and property investors may want to reassess their rental yield forecasts and returns and possibly consider alternative investments.

4. Review your dividend tax liability

You may want to review how much of your dividend income sits outside tax-efficient accounts, and ensure you’re making full use of ISA allowances or other suitable wrappers.

You could also adjust your long-term investment planning to reflect the impact of greater dividend tax drag. If you’re self-employed or a company director, consider revisiting how you draw income from your business to ensure it remains as tax-efficient as possible.

5. Factor in property-related taxes

If you currently own or are considering buying a property valued at over £2 million, it’s important to take the future surcharge into account when planning your cashflow and long-term financial strategy.

This additional annual cost could affect mortgage affordability, investment decisions, and overall financial planning, so factoring it in now can help you avoid surprises and make more informed property and investment choices.

6. Get professional financial advice

The Autumn Budget 2025 introduces changes that could affect your income, benefits, savings and pension. Understanding these adjustments can help you plan for the future, whether tax thresholds, benefit limits or wage increases.

If you’re unsure what to do, speaking to a regulated financial adviser can:

• Analyse how the latest reforms could impact your retirement income.
  
• Support you in planning effective income drawdown strategies.
  
• Offer personalised, FCA-regulated recommendations tailored to your financial goals.
