A leading pensions consultancy has warned Chancellor Rachel Reeves that sweeping changes to pension tax relief risk provoking a repeat of the 2012 "Omnishambles" Budget — where measures were rapidly reversed after causing uproar — and could unravel almost immediately if attempted before or in the next Budget on 26 November.
Lane Clark & Peacock (LCP) says proposals under consideration to raise billions of pounds, including reducing higher-rate tax relief on pension contributions, capping tax-free lump sums and curbing salary sacrifice arrangements, would face entrenched political, legal and administrative obstacles and are likely to raise far less money than expected in this Parliament.
LCP’s report, titled "How to avoid an Omnishambles Budget," argues that while cutting the higher-rate uplift in pension tax relief may appear an attractive option for a cash-strapped Treasury, the practical consequences create "multiple traps for the unwary." The consultancy estimates the net cost of current tax relief for pensions at more than £50 billion and notes most of that value accrues to higher earners, but says reforms would also harm lower-paid workers and some public-sector staff with generous, long-service pension arrangements.
"The political backlash against such reforms could easily echo previous 'Omnishambles' Budgets where a U-turn was made within a matter of weeks," said Steve Webb, a partner at LCP and co-author of the report. Webb, a former pensions minister, warned that large structural changes would require lengthy consultation, complex legal amendments and major changes to administration and payroll systems, so any additional revenue is unlikely to materialise quickly.
The LCP analysis highlights that removing salary sacrifice would particularly disadvantage those on modest earnings. More than three million basic-rate taxpayers could lose out, the consultancy said, while employers would face higher costs and additional administrative burdens that could undermine the provision of workplace pensions and depress saving.
Capping the tax-free lump sum has already had behavioural effects: fear of changes is credited with driving a sharp rise in withdrawals across the pensions market last year, a trend industry experts have warned may be continuing despite appeals for people not to make hasty decisions. LCP says capping tax-free cash would be seen by many approaching retirement as "moving the goalposts," and would therefore require extensive transitional protections that further reduce near-term revenue.
Tim Camfield, a report co-author and principal at LCP, said removing features such as salary sacrifice could make employees paying the basic rate of tax losers and penalise employers that try to provide high-quality workplace pensions. The report lists five core risks for the Chancellor: breaking manifesto commitments not to raise taxes on workers, disproportionately affecting public-sector staff, failing to raise meaningful sums during the current Parliament, adding burdens on employers already facing higher costs and undermining pension saving at a time when the Government estimates some 14 million workers are not saving enough for retirement.
The consultancy also noted the broader fiscal context, saying reforms could add to pressures on employers already asked to absorb a multi-billion-pound rise in National Insurance contributions in the previous Budget.
When asked for comment, a Treasury spokesperson said: "We do not comment on speculation around tax changes, but remain committed to helping our pensioners live their lives with dignity and respect, which is why in April the basic and new state pension increased by 4.1 per cent. Pensioners will receive a boost of up to £470 to their income in 2025-26. Our commitment to the triple lock means millions will see their pension rise by up to £1,900 this parliament."
LCP applied a red-amber-green rating to the three policy options it examined — reforms to tax relief, limits on tax-free cash and ending salary sacrifice — and concluded that each carried significant downside risks. The consultancy’s overall counsel is that the Chancellor would be better advised to avoid major, immediate changes to pension tax relief if she wishes to avert a rapid reversal of policy and the political fallout that would follow.
The Government faces a narrow window before the scheduled Budget to decide whether to pursue reform amid scrutiny over how best to plug gaps in public finances. LCP’s report underscores the technical complexity and political sensitivity of pension tax changes and cautions that measures intended to be revenue-raising could deliver little in the short term while imposing lasting disruption for savers and employers alike.
