Britons are bracing for change ahead of John Healey’s first Budget as chancellor on 28 October, with plenty of speculation over what he will do to fill the gap in the public finances is building.
The state pension triple lock, which raises the pension each year by the highest of inflation, average earnings growth or 2.5%, has dominated recent coverage after Andy Burnham pledged to get rid of it.
The prime minister said the change, which would not take effect until 2030, would help fund a national care service, leaving this Budget to deal with the immediate gap in the public finances.
Government borrowing hit £18.3bn in August, £3.5bn above the Office for Budget Responsibility's forecast and almost 20% higher than a year earlier. That gap is behind nearly every rumour.
Some Budget ideas are floated in advance to test public reaction. Although nothing below is confirmed policy, each rumour could be rooted in some truth. All will have different implications for investors' money.
Susannah Streeter, chief investment strategist at Wealth Club, said: "The Burnham fiscal bind has wound even tighter, giving him very little room for manoeuvre at the Budget.
“It's highly likely that there will only be tinkering at the end of October given there's no headroom for spending splashes, despite pledges to alleviate cost-of-living pressures.
“So, focus is likely to turn once again to making up the shortfalls through higher taxes, with speculation set to intensify about potential increases to capital gains tax, which inevitably will be accompanied by concerns about the potential impact of this on investment and entrepreneurship and growth prospects."
Capital gains tax
Reports said Burnham and Healey were examining a move to bring capital gains tax (CGT) rates closer to income tax rates. The proposal, which would hit anyone selling shares or funds held outside an ISA or SIPP, as well as second properties, would raise money without breaking Labour's manifesto pledge on income tax, National Insurance and VAT.
Dan Coatsworth, head of markets at AJ Bell, said: “Speculation that capital gains tax rates could rise at the Budget may encourage some investors to bring forward plans to sell investments held outside ISAs and pensions.”
The incentive to sell is strongest for those with gains well above the £3,000 annual allowance, particularly holders of long-term winners, he noted. AJ Bell's own dealing account data shows Rolls-Royce shares up 1,080% over five years, Nvidia up 899% and BAE Systems up 261%: investors sitting on gains of that size are the most exposed to any rate change.
Streeter saw it the opposite way: "For investors, the prospect of a higher CGT bill could mean some simply decide not to sell assets and hang onto them instead," she said.
For those who do want to act, Bed & ISA and Bed & SIPP transactions offer a route to shelter future gains: selling and immediately repurchasing the same assets inside an ISA or pension.
Investors pay any CGT due now, but growth from that point is protected. Still, nobody should let the tax tail wag the investment dog: any decision to sell should be driven by investment objectives first, said Coatsworth.
Pensions and tax-free cash
The tax-free lump sum, currently capped at £268,275, faces its now-annual rumour of a cut. It has resurfaced ahead of several Budgets and been ruled out each time, but the uncertainty is prompting action among pension savers.
Sarah Coles, head of personal finance at AJ Bell, said: "There will be some people who have drawn up their plans carefully, for whom this makes perfect financial sense."
"However, there are others taking it purely because of worries about what might lie in the Budget – particularly in the past two years – who could be doing immeasurable damage to their retirement income."
AJ Bell analysis of the latest Financial Conduct Authority (FCA) data for 2025/26 estimated people took £14bn more from their pensions than they would have without the speculation. This is up from the £10bn excess that people pulled ahead of the first Labour Budget in 2024.
A survey of 449 advisers by Aberdeen Adviser found 92% had received client calls about early pension access driven by Budget speculation, with tax-free cash the single biggest concern, cited by 56%, as Richard Denning, chief executive of Aberdeen Adviser, noted.
"The fact that nearly every adviser we asked was already fielding calls from worried clients over taking their tax-free cash, or making withdrawals earlier than planned, is concerning," he said.
Acting early has risks. Reinvesting a withdrawn lump sum can trigger HMRC's recycling rules, and anyone who takes drawdown income alongside their tax-free cash sees future pension contributions capped at a £10,000 Money Purchase Annual Allowance, with no carry-forward.
Income tax and the personal allowance
Labour's manifesto pledge not to raise income tax, National Insurance or VAT on working people leaves the chancellor limited room on thresholds, which are already frozen until 2031. Rumours here are split: either the freeze extends further, dragging more earners into higher bands as wages rise and bringing more money int o the Treasury, or the government looks to loosen the strings on people’s purses by upping the personal allowance from £12,570 to a mooted £15,570.
Polling by AJ Bell and Opinium found the personal allowance rise is the single most popular potential change, backed by 61% of respondents, while keeping thresholds frozen beyond 2031 is among the most feared, opposed by 39%.
"Andy Burnham has made it clear he will stick to Labour's manifesto pledges of not raising income tax or National Insurance," said Coles.
Any rise in the personal allowance would still need funding from somewhere else, which is one reason CGT has drawn so much attention as an alternative revenue source.
Wealth tax, inheritance tax and property
A broader annual wealth tax is off the table by most accounts for now. Burnham has not ruled it out entirely, but has said that his government will not go "straight to" one of these as a default way to get more cash.
The same AJ Bell and Opinium poll cited above found 44% of people support a wealth tax on total assets, the second most popular change tested, a figure that likely reflects an assumption among respondents that it would not apply to them.
"In reality, this kind of tax is fraught with difficulties, including for those who may live in expensive properties but have a lower income, so would struggle to pay the bills," Coles said.
On top of that, the mansion tax threshold, due to apply from 2028, is rumoured to fall from £2m to £1.5m, roughly doubling the number of homes affected to around 300,000.
Jay Lawrence, investment director at Rathbones, reported growing client anxiety about the cumulative effect of changes across pensions, inheritance tax and CGT rather than any single measure. "Many clients describe it as a death by a thousand cuts rather than one dramatic policy announcement," he said.
