Rachel Reeves faces mounting fiscal pressure to introduce tax increases in her autumn Budget, after updated forecasts from the National Institute of Economic and Social Research (NIESR) warned of a £41.2 billion shortfall in the government’s current budget plans. The thinktank’s latest projections raise the prospect of substantial revenue measures that could reverberate across the UK insurance industry.
The research body cautioned that unless corrective action is taken, the Chancellor is set to violate her own fiscal rules - chiefly, that day-to-day public spending be financed entirely from tax receipts by the 2029–30 fiscal year. To preserve a £10 billion safety margin, Reeves would need to raise or save a total of £51.1 billion.
“Things are not looking good for the Chancellor,” said Stephen Millard, NIESR’s deputy director for macroeconomics. “She will need to either raise taxes or reduce spending, or both, in the October Budget if she is to meet her fiscal rules.”
The warning leaves Reeves grappling with what NIESR dubbed an “impossible trilemma”: reconciling legally binding fiscal commitments with existing public spending priorities and Labour’s pledge not to raise taxes on “working people.” While speculation continues around the scope for wealth or property taxation, the thinktank’s clearest proposal remains a rise of 5p on both the basic and higher rates of income tax - enough to bridge the entire gap.
David Aikman, NIESR’s director, emphasised that restoring confidence in the UK’s fiscal trajectory would “require a determined attempt to rebuild the fiscal buffer and that will inevitably involve gradual but sustained tax increases or spending cuts.”
For insurance professionals, such fiscal tightening presents a dual-edged challenge. From the demand side, rising personal taxes - especially if extended via frozen thresholds - could depress uptake of life, health, and long-term savings products. Consumers are likely to downgrade discretionary cover or delay premium-heavy products such as whole life insurance and annuities in favour of cheaper or deferred alternatives.
In commercial lines, a higher tax burden on business owners may curb investment and hiring intentions, reducing demand for property, liability, D&O, and workers’ compensation cover. In tandem, insurers may face increased pricing pressure from corporate buyers seeking to preserve margins in a higher-tax environment.
On the investment side, elevated taxation - particularly on high-net-worth individuals - could divert capital from investment-linked insurance products such as variable annuities. A reduced inflow may, over time, shrink the investable asset base supporting long-term liabilities, with implications for solvency and pricing.
Nevertheless, rising tax rates may also prompt innovation. Life and savings insurers, especially those operating in markets with tax-deferred policy structures (e.g., indexed universal life or hybrid LTC-life products), could see renewed interest from affluent clients seeking tax efficiency. Financial advisers may play a greater role in guiding insurance allocations, potentially benefitting broker-centric distribution models.
Further, NIESR’s call for tax reform - such as revisiting property valuations last assessed in 1991 or even replacing council tax with a land value tax - could pave the way for targeted product development in protection and commercial property lines.
The fiscal pressures come against a backdrop of sluggish growth and persistent inflation. NIESR projects GDP growth of just 1.3% this year, barely changed from its May forecast. Inflation, currently running at 3.3%, is not expected to return to the Bank of England’s 2% target before early 2028.
Nonetheless, modest monetary relief is expected. The Bank is forecast to reduce its base rate from 4.25% to 3.75% by year-end, though this may do little to offset the squeeze on disposable incomes if tax rises proceed.
Conservative shadow chancellor Sir Mel Stride was quick to condemn the government’s handling of the economy. “Businesses are closing, unemployment is up, inflation has doubled and the economy is shrinking. And Labour are refusing to rule out more damaging tax rises on investment,” he said.
For general insurers, the potential macroeconomic drag could lead to reduced claims frequency in motor and commercial lines - fewer miles driven, fewer contracts signed - but also lower premium growth overall. Persistent inflation, meanwhile, will continue to complicate reserving and pricing.
