UK Autumn Budget 2026: Key Insights and Planning Tips for Your Finances

Like many of you, we eagerly awaited the 2026 Autumn Budget with bated breath. With inflation currently at 3.5% and weeks of speculation about tax rises, we were all hoping for good news about our tax rates, savings, pensions and retirement plans.

At first glance, this was a steadier Budget than many of us feared, with the headline rates of income tax, National Insurance and VAT left unchanged. However, on closer inspection, there are some significant changes to savings, ISAs and pensions that could impact your finances, and a major inheritance tax change is still on its way.

Below, we explain the main points from the UK Budget 2026 and what they could mean for your finances; along with some practical advice to help you plan ahead.

Key Points from the UK Autumn Budget 2026

Income Tax Thresholds Stay Frozen

The Budget announcement:

Income tax rates and the £12,570 personal allowance remain unchanged following the Autumn Budget, and the thresholds will remain frozen until April 2031 (as set out in last year’s Budget). 

What this means for you:

As the thresholds are not rising with inflation, any pay rise or pension increase you receive is more likely to push some of your income into a higher tax band. This means you may pay more tax over time even though the rates have not changed; which makes it more important than ever to use your tax allowances each year.

Higher Tax on Savings and Rental Income

The Budget announcement:

From 6th April 2027, the income tax on savings interest and rental income will rise by a further two percentage points. The new rates will be 24% for basic rate taxpayers, 44% for higher rate and 49% for additional rate.

What this means for you:

If you hold significant cash savings outside of an ISA, or you receive rental income, then you will pay more tax from April 2027. There are benefits to holding more of your savings and interests inside ISAs and pensions to help reduce the impact. It is worth reviewing how your money is held before the new rates apply.

Cash ISA Allowance is Retained

The Budget announcement:

The planned cut to the cash ISA allowance will no longer go ahead, which means people under 65 can continue to save up to £20,000 in their ISA. A new First Time Buyer ISA will also be introduced in April 2029 and will replace the current Lifetime ISA.

What this means for you:

Tax on savings interest is continuing to rise, which makes ISAs even more valuable than ever, as any interest or growth inside them is tax-free. Ensure you make full use of your ISA allowance each year to protect your savings from tax. 

New Tax-Free Pension Allowance

The Budget announcement:

A new Pension Tax Allowance comes into effect from 6th April 2027 for people who are above State Pension age (or reach State Pension age within the 2027/28 tax year). Those with a total income of no more than the full annual value of the State Pension (£13,036.40 for 2027-28) will receive the full Pension Tax Allowance and will therefore not be brought into paying tax. For pensioners earning more, the allowance will be tapered by £1 for every £3 exceeding the allowance (resulting in no allowance for those earning more than £13,319).

The Government has committed to uprating the Pension Tax Allowance in line with the full annual value of the new State Pension until 5th April 2030.

Other existing rules stay the same: the triple lock remains until April 2029, tax relief on pension contributions continues, and unused pension funds will fall into the value of a person’s estate for Inheritance Tax purposes from 6th April 2027.  

What this means for you:

Pensions remain one of the most tax-efficient ways to save for retirement. However, from April 2027, a pension you pass on may be subject to inheritance tax at 40%. Make a plan for how and when you will draw from your pension. 

Inheritance Tax Thresholds Frozen

The Budget announcement:

Inheritance tax thresholds remain frozen until April 2031, with a nil-rate band of £325,000 and a residence nil-rate band of £175,000 for those who qualify.

What this means for you:

Combined with the pension change from April 2027, your family may be more likely to face an inheritance tax bill, so it is worth starting your estate planning early. Remember, you can gift up to £3,000 a year tax-free, and larger gifts usually fall outside your estate if you live for seven more years.
