Chancellor rules out major capital gains tax hike ahead of October 28 Budget, leaving banks and spending choices centre stage

LONDON, October 20, 2026 , Chancellor of the Exchequer John Healey has decided not to press ahead with a large scale increase in Capital Gains Tax, ruling out proposals to align CGT with ordinary income tax rates ahead of the Autumn Budget on October 28. The move, first widely reported on October 20, removes what had been described inside government as the most disruptive option for closing the Treasury’s fiscal headroom.

What the decision means

The Chancellor’s rejection of the headline CGT equalisation option narrows the menu of revenue-raising measures available to deliver on the government’s fiscal rules and to fund priorities such as defence spending and cost of living support. Tax rises on capital or wealth had been prominent in prebudget discussion and in some senior Labour circles as one way to increase receipts without hiking income tax for employees.

Officials and market participants expect the Budget to instead focus on measures that target specific sectors or income streams rather than broad-based increases to investment taxes. In practice that means increased levies on the banking sector and other targeted reforms have become the likeliest instruments to raise the bulk of any new receipts announced by the Chancellor.

Why Healey turned away from a big CGT change

Ministers and Treasury advisers concluded that equalising CGT with income tax could be counterproductive. Analysis circulated among decision makers warned that a sharp rise could prompt wealthy taxpayers to delay disposals or change residency, reducing near term yields. That modelling, combined with concerns about deterring investment at a delicate moment for the economy, appears to have persuaded the Chancellor that the costs outweighed the fiscal benefits.

Those calculations reflect longstanding tax policy trade offs. Capital gains taxes are more sensitive to behavioural responses than many other taxes, because taxable events can be timed and in some cases avoided through legal restructuring. Policymakers weighing CGT reform must balance revenue potential with wider effects on investment, housing market behaviour and the attractiveness of the UK for mobile capital.

Bank levies and narrower measures now in the spotlight

With the CGT nuclear option off the table, attention has shifted to banking taxes. The sector has reported elevated profits this year, and both union pressure and political rhetoric have increased the appetite for a bank levy or a surcharge on banking profits as a way to raise funds while maintaining an explicit growth focus elsewhere in the tax system.

Options likely to be considered include increasing the rate of the bank surcharge or reinstating parts of the bank levy that were loosened in recent years. Such measures are technically narrower than a broad CGT rise, but they still carry economic and political consequences. Banks have warned that higher levies could reduce lending capacity and investment in the UK, while consumer groups have argued that taxing windfall profits is justified when sectors are posting outsized returns.

Market and business reaction

Markets and corporate directors typically prefer policy clarity. The Chancellor’s rejection of an equalisation of CGT will be read as a reassurance by many investors and business owners worried about sudden changes to the tax treatment of asset disposals. Financial markets reacted earlier this week to the possibility of sectoral taxes with pressure on bank shares, and clarity on CGT may calm some of that volatility ahead of the Budget.

Business groups welcomed the signal that the government wants to protect the investment environment. However, trade associations and unions are already lobbying for compensating measures to protect public finances and vulnerable households. Reconciling those demands will frame the political debate in the run up to the Budget.

Political stakes and what to watch on October 28

The Chancellor still faces a delicate fiscal tightrope. The government has set self imposed fiscal rules that limit borrowing for day to day spending. With borrowing costs elevated relative to last year, the headroom to absorb extra spending is smaller than ministers had hoped earlier in 2026. That makes the choices at the Budget consequential for the medium term path of public finances.

Key things to watch on October 28 include the size and structure of any bank levy, whether the Chancellor opts for one off or recurring revenue measures, and targeted support packages for households facing rising bills. The Budget may also include administrative changes to the tax system that generate smaller but steady returns, such as reforms to platform taxation and enforcement measures.

Why this matters for UK business and households

Tax policy signals influence investment planning, corporate structuring and household expectations. By ruling out a headline CGT alignment, the Chancellor has signalled that sustaining a pro investment backdrop remains a priority. At the same time, shifting the burden toward sector specific measures will keep pressure on industries such as banking, and create distributional questions about who ultimately bears the cost.

For businesses, the Budget will reveal whether policymakers will rely on targeted sector levies and administrative reforms or whether other broader measures will be used to meet fiscal targets. For households, the key question is whether the Chancellor will balance any new taxes with support for cost of living pressures, particularly in energy and housing.

As the October 28 Budget approaches, attention will focus on the fine print of the measures the Chancellor chooses, and on how ministers plan to marry fiscal discipline with growth and fairness objectives in a constrained fiscal environment.
