UK Think Tank Urges Chancellor to Raise Middle-Earner Taxes to Fund Higher Defence Spending Ambitions

The Quick Take

• The Resolution Foundation urges Chancellor Healey to raise taxes on middle earners to fund significantly higher UK defence spending.
• The UK's internationally low 'tax wedge' provides fiscal headroom, but any increase would reduce household disposable income.
• Higher UK defence budgets would benefit domestic contractors like BAE Systems while weighing on gilts and consumer stocks.

The Resolution Foundation has urged Chancellor John Healey to raise taxes on middle-income earners as the only fiscally credible route to funding significantly higher defence spending. The argument centers on the UK's relatively low 'tax wedge'—the combined burden of income tax and social contributions as a share of labour costs—which sits below the OECD average and provides structural fiscal headroom. Former Chancellor Healey resigned from Keir Starmer's government in June over defence funding disagreements, making his subsequent advocacy through the think tank route politically significant and signaling sustained pressure on Treasury to act.

A middle-earner tax rise in the UK would reduce disposable income across the largest household income cohort, creating headwinds for consumer discretionary retailers, housing activity, and personal finance products. UK gilts could react ambiguously: higher taxes improve the fiscal trajectory, potentially supporting gilt prices, but the associated increase in defence spending raises expenditure, limiting debt reduction. UK defence stocks—BAE Systems, Rolls-Royce, QinetiQ—would be direct beneficiaries of increased MoD procurement budgets. Pension funds with significant gilt holdings would benefit from higher long-run yields if the spending plans widen the deficit.

Watch the UK autumn budget statement for formal signals on defence spending commitments and any accompanying tax package, which will determine whether the Resolution Foundation's proposal becomes government policy. The macro variable is NATO's 2% GDP defence spending target: if the UK government commits to exceeding it, the fiscal arithmetic forces the tax-rise debate into concrete policy territory. Upcoming UK CPI and consumer confidence data will measure whether households have the financial resilience to absorb a tax increase, directly influencing the political feasibility of the Resolution Foundation's recommendation.
