With tight fiscal headroom and manifesto limits, Healey's October 28 budget will centre on three wealth-tax choices, tweaks to capital gains, new property levies or a standalone wealth tax, each carrying different revenue and political risks.
John Healey has repeated Labour's 2024 pledge not to raise the rates of income tax, VAT, corporation tax or social security contributions, yet official March forecasts that leave only about £24 billion of fiscal leeway force the chancellor to hunt for other revenues before his October 28 budget. That pins his options to wealth and property taxes rather than headline rate rises. Capital gains tax raised £24 billion in 2025-26, council tax brought in £54 billion and stamp duty £17 billion, and one academic reform of CGT was modelled to raise about £11 billion a year while HMRC warns some CGT rate increases could cut receipts by up to £3.6 billion through avoidance. The Resolution Foundation says meeting Labour's 3.5 percent of GDP defence pledge would need roughly £28 billion a year and could mean asking average workers to pay more. Healey must choose by October 28 which revenue route to prioritise, even as he refuses to comment on tax policy until the budget and signals a fuller plan will wait for next year's spending review.
What Happened
John Healey faces a tight choice at his first budget on October 28: he must find extra revenue without raising headline tax rates, in line with Labour's pledge. A Resolution Foundation report warned that to meet the party's commitment to devote 3.5% of GDP to defence by 2035, average workers would likely need to pay more. Healey has refused to comment on tax policy before the budget to avoid speculation and plans to wait until next year’s spending review before setting out a full plan amid higher borrowing costs and pressure to fund expanded social care and defence commitments.
The Numbers
Fiscal headroom is tight. March budget forecasts left roughly £24 billion of leeway to meet the government’s target of balancing day to day spending with tax receipts by 2029-30.
That matters because the government raised about £1.1 trillion in tax in 2025-26, including sizeable property and wealth receipts such as capital gains tax, council tax and stamp duty, which together make up a significant portion of the haul.
Options that target wealth are not small. One academic reform of capital gains tax was estimated to raise about £11 billion a year, but HMRC warned that some CGT rate rises could reduce revenue by up to £3.6 billion through avoidance, creating a narrow trade-off between headline rates and actual receipts.
Manifesto limits rule out hikes to the headline rates of income tax, VAT, corporation tax or social security contributions, which funnels debate towards wealth and property levies rather than broad-based tax rises.
Meeting Labour’s pledge to devote 3.5% of GDP to defence would cost about £28 billion a year, and the Resolution Foundation says doing so without cuts would probably require asking average workers to pay more.
Healey has framed the budget around "wealth creation" and growth, signalling where he wants political space to be found.
All of it means the chancellor faces a small menu at the October 28 budget: press harder on capital gains, squeeze property taxes, or introduce a new wealth levy, and he must pick which route to prioritise.
Why It Matters
Healey’s October 28 decision will determine whether the narrow margin in the public finances is covered by taxing wealth or by shifting costs elsewhere, referring back to the limited fiscal leeway outlined in the March budget forecasts.
Manifesto constraints rule out raising headline rates of income tax, VAT, corporation tax or social security contributions, so the fiscal levers left are concentrated on wealth and property. That limits Healey’s room for manoeuvre and raises the political stakes of any move.
The scale of the choices is concrete. Capital gains tax, council tax and stamp duty contributed substantial amounts in 2025/26. One academic-style reform of capital gains was estimated to raise roughly £11 billion a year, but HMRC warned some rate rises could cut revenue by as much as £3.6 billion through avoidance. These figures show that small changes can have outsized fiscal effects or trigger behavioural shifts that reduce yield.
There is a distributional and political trade-off. Changes to capital gains mainly target asset owners, a property levy would hit homeowners and the housing market, while a standalone wealth tax introduces new valuation and collection challenges. At the same time, the Resolution Foundation has warned that meeting substantially higher defence spending would probably require asking average workers to pay more, so the choice also affects who carries the burden.
Practically, Healey must pick which route to prioritise in the budget on October 28, even as he has signalled a fuller plan for meeting the defence pledge will wait until next year’s spending review. The October choices will set the headline direction for that later reckoning.
What's Next
Healey has to pick a revenue route for his first budget on October 28, and the combination of tight fiscal headroom and Labour’s manifesto limits makes that choice sharply constrained. He has refused to discuss tax policy ahead of the budget, saying he will not fuel speculation, and repeated the manifesto pledge not to raise the rates of income tax, VAT, corporation tax or social security contributions.
The decision set
- Capital gains tax is an obvious lever. CGT already raised £24 billion in 2025-26, and one academic reform has been estimated to bring in about £11 billion a year. But HMRC has warned that some CGT rate rises could cut, not raise, revenue by up to £3.6 billion because of avoidance.
- Property-focused levies are the other obvious route. Council tax produced £54 billion and stamp duty £17 billion in 2025-26, so adjustments to property taxation are politically and technically plausible ways to raise money.
- A standalone wealth tax remains on the table as a headline option, but it carries its own modelling, collection and political hurdles and would compete for space with the other two choices.
Each option carries a trade-off between headline revenue, behavioural responses and political acceptability. The budget forecasts published in March left only a narrow margin to meet the government’s medium-term targets. At the same time, the Resolution Foundation has flagged that meeting Labour’s pledge to devote 3.5% of GDP to defence by 2035 would cost about £28 billion a year, and that raising those sums may ultimately require asking average workers to pay more.
Healey has signalled he will wait until next year’s spending review to set out a full plan for meeting the 3.5% defence target. That means the budget on October 28 must pick which single route to prioritise now, while leaving detailed implementation and longer-term trade-offs to the spending review. Expect ministers and markets to test the political limits of any proposal fast.
The immediate test is whether Healey uses October 28 to raise capital gains, introduce a property levy, or opt for a standalone wealth tax; the date to watch is October 28.
