With major tax bases like income tax, VAT, and national insurance potentially off-limits, the government is exploring other revenue streams, including property, capital gains, and pension policies.
Despite previous reluctance from the pensions minister, speculation about changes to pension policy is rife, leading to a 36 per cent increase in pension withdrawals in 2024/25 as savers adjust their plans.
Two key proposals under consideration are introducing a flat rate of pension tax relief, potentially raising £15bn annually, and capping the tax-free pension lump sum closer to £100,000, which could yield £2bn.
While the Chancellor has hinted at tax rises for the wealthy, concerns have been raised that such pension reforms could negatively impact public sector workers and prove politically contentious.
