Every autumn brings a wave of Budget speculation, and this year there’s more of it than usual. This year’s Autumn Budget will be delivered in unusual circumstances, as Prime Minister Andy Burnham and Chancellor John Healey will have only been in their roles for a little over three months on the day of the announcement. A new team, a tight set of public finances and an unsettled global backdrop make for plenty of headlines. 

Our view is simple. Good financial planning doesn’t depend on guessing correctly. It depends on knowing what’s already fixed, understanding what might change, and having your affairs organised well enough to respond quickly once the facts are in. So here’s a plain-English separation of the confirmed from the conjecture.

The date and the tone

On Wednesday 28 October 2026, the Chancellor will deliver the Autumn Budget, alongside the publication of an economic and fiscal forecast from the Office for Budget Responsibility. 

The clearest signal so far came at Labour’s conference in Liverpool this week. Healey pledged to use the budget to inject hope into Britain’s economy while sticking to the government’s fiscal rules, arguing there is “nothing progressive” about losing control of public finances. Read between the lines and the message is that revenue-raising measures remain firmly on the table. 

Why the pressure is on

The key number to understand is “headroom”, the margin by which the government meets its own borrowing rules. Deutsche Bank has calculated that soaring government borrowing costs and high inflation have wiped out £15bn of the £23.6bn cushion laid out in the Spring Statement in March. Other estimates vary, with the Resolution Foundation reckoning headroom had shrunk to below £8 billion by late August. 

That said, the Treasury has some choice here. The Treasury and No 10 are reportedly debating whether to allow a lower level of fiscal headroom than was forecast in March, which would lessen the need for tax rises or spending cuts. In other words, nothing is inevitable, which is exactly why acting on rumour is a mistake. 

What’s already confirmed

Much of what will affect Lancashire investors over the next few years has already been legislated. The biggest changes to personal finances in the next 18 months were legislated in the November 2025 Budget and Finance Act 2026, and will happen whatever the Chancellor says on 28 October. These include: 

Frozen tax thresholds. The £12,570 Personal Allowance and the £50,270 higher-rate threshold are frozen until April 2031, so every pay rise pulls more income into tax and more people into the 40% band. For many of our clients, this “fiscal drag” is quietly doing more damage than any headline tax rise. 

Higher tax on investment income. Dividend tax already went up this April to 10.75% for basic-rate and 35.75% for higher-rate taxpayers. From April 2027, interest outside an ISA is taxed at 22%, 42% and 47% instead of 20%, 40% and 45%, and rental profits face the same 2-point increase. 

Pensions and inheritance tax. From April 2027, most unused pension pots and lump sum death benefits join the estate and can be taxed at 40% above the allowances. This is a significant shift for anyone who has treated their pension as a tax-efficient way to pass on wealth. 

Salary sacrifice. From April 2029, National Insurance relief on salary sacrifice pension contributions is limited to the first £2,000 a year. 

The “mansion tax”. Homes in England worth £2 million or more will pay £2,500 a year from April 2028, rising to £7,500 above £5 million. Relatively few Lancashire homes will be caught, but it’s worth watching for reasons we’ll come to. 

Where your allowances stand today (2026/27)

These are the figures that matter for planning right now:

Your ISA allowance is £20,000 for this tax year. From 6 April 2027, the Cash ISA sub-limit for under-65s reduces to £12,000 within the overall £20,000. 

The Pension Annual Allowance is £60,000, or 100% of earnings if lower, and unused allowance from the previous three tax years can be carried forward if you were a member of a registered pension scheme in those years. Higher earners should note the taper, which can reduce this significantly. 

The Lifetime Allowance has gone, but limits on tax-free cash remain: the Lump Sum Allowance is £268,275 and the Lump Sum and Death Benefit Allowance is £1,073,100. 

The CGT Annual Exempt Amount is £3,000 for individuals, and for gains above that, the rates are 18% for basic rate taxpayers and 24% for higher and additional rate taxpayers on most assets. 

What’s rumour (and how seriously to take it)

Capital gains tax. Talk of full alignment with income tax has quietened. The idea most often reported is ending the “uplift on death”, under which assets are revalued at death so that the gain built up during life is never taxed. For families holding property or long-held shares, this would be a meaningful change. 

Pension tax relief. BDO describes pension tax relief as the most-discussed lever that has never quite been pulled. With two pension changes already booked, many forecasters expect no third this year, but it can’t be ruled out. BDO

Property. There are reports that the surcharge’s £2 million threshold could be lowered to £1.5 million, which would bring in roughly 100,000 more homes. That would put more of the county’s higher-value homes in scope. 

Farms and family businesses. One potentially positive note for Lancashire’s farming families: the Prime Minister has said he is willing to look again at the restriction of agricultural property relief for farmers, which took effect in April 2026. Willingness to look is not a commitment, but it’s worth watching closely. 

What’s been ruled out matters too. Burnham pledged to keep Labour’s commitment not to raise the rates of income tax, VAT, corporation tax or social security contributions. 

What to actually do now

The most important advice is also the least exciting: don’t act on rumours. Tax changes normally apply from the date they are announced or from the next 6 April, and Budgets sometimes include anti-forestalling rules that catch transactions rushed through beforehand. Moving money or crystallising pensions out of fear has cost people dearly in recent years. 

That said, there are sensible steps that make sense regardless of what’s announced:

Use this year’s allowances. If you hold cash savings and are under 65, this is the last tax year you can put the full £20,000 into a cash ISA. Couples should make sure both partners’ ISA and CGT allowances are being used.

Review pension contributions and carry forward. If you have unused annual allowance from previous years, there may be scope to make larger contributions while current reliefs are known quantities.

Check your pension nominations. With pensions entering the inheritance tax net from April 2027, an out-of-date expression of wish form could prove costly. Pensions left to a spouse or civil partner remain exempt; those left to children may not be.

Get your paperwork in order. Knowing your portfolio values, gains position and pension details now means you can act within days of the Budget, not weeks.

Be ready, not reactive

The families and business owners who come through Budget season best aren’t the ones who guessed right. They’re the ones who were organised enough to respond calmly once the detail was published.

If you’d like a clear picture of where you stand before 28 October, book a portfolio and pension review with our chartered team. We’ll make sure your plan is in shape now, so that whatever the Chancellor announces, you can act on it quickly and with confidence.
