Key Points
1p loophole could undermine Reeves's 22% ISA interest tax from April 2027.
Moneybox urges government to retain Lifetime ISA for 1.5 million active savers.
Proposed replacement product not expected until 2028, creating uncertainty.
Dividend tax rates already rose 2 percentage points in April 2026.
Chancellor Rachel Reeves announced a 22% tax on ISA interest income starting April 2027, but a discovered 1p loophole threatens to undermine the reform. Financial firms and savers are questioning whether the policy will work as intended. The government is also reviewing the Lifetime ISA, with a replacement product not expected until 2028.
How the 1p Loophole Works
The loophole allows savers to withdraw and redeposit ISA funds in 1p increments to reset interest calculations. This strategy could help savers avoid or reduce the 22% tax on accumulated interest. The loophole has sparked debate on whether Reeves’s tax reform can achieve its intended revenue target.
Lifetime ISA Under Review
The government is conducting an ongoing review of the Lifetime ISA, which serves dual purposes for first-time home buyers and retirement saving. Moneybox, the UK’s largest LISA provider, urged the government to fix rather than replace the product. The company supports 1.5 million active savers and argues the LISA is working for the vast majority of users.
Moneybox’s Three-Point Plan
Moneybox proposed retaining the LISA for new customers instead of introducing a replacement. The firm also calls for annual reviews of the £450,000 house price cap and reducing the withdrawal penalty from its current level to 20 percent. A replacement product is not expected until 2028, creating uncertainty for existing savers.
Dividend Tax Changes Already in Effect
From April 2026, dividend tax rates increased by two percentage points. The ordinary rate rose to 10.75 percent from 8.75 percent, and the upper rate to 35.75 percent from 33.75 percent. Dividends within ISAs remain tax-free, making tax-advantaged wrappers more valuable as the government tightens tax on investment income.
Final Thoughts
The 1p loophole threatens Reeves’s ISA tax plan, while Moneybox argues the Lifetime ISA needs fixing, not replacing. Savers should review their ISA strategy before April 2027 as tax rules tighten.
FAQs
The loophole allows savers to withdraw and redeposit ISA funds in small increments, potentially resetting interest calculations to avoid the 22% tax on accumulated interest.
The 22% tax on ISA interest income begins in April 2027. Dividends held within ISAs remain tax-free under current rules.
Moneybox argues the LISA serves 1.5 million active savers and supports better long-term financial outcomes. Fixing the product is preferable to replacing it with a new scheme in 2028.
