HMRC has announced that from April 2027, cash interest held in stocks and shares ISAs will be subject to a 22% tax. This new rule will apply to any cash held within these investment accounts, including uninvested cash and cash from dividends or sales.
Background of the Change
Currently, interest earned on cash within a stocks and shares ISA is tax-free, as long as it remains within the ISA wrapper. The change is part of a broader effort by HMRC to align the tax treatment of cash held in ISAs with other savings accounts. According to HMRC, the move is expected to raise approximately £1.5 billion annually by 2030.
Impact on Savers
The 22% tax will be applied to interest earned on cash balances over a certain threshold, which is yet to be confirmed. Experts warn that this could significantly reduce returns for savers who hold large cash positions within their ISAs. "This is a major shift in policy that will catch many investors off guard," said Sarah Jones, a tax advisor at PricewaterhouseCoopers. "It's essential for individuals to review their ISA holdings and consider whether holding cash within these accounts still makes sense."
What This Means for Investors
Investors who use their stocks and shares ISA to hold cash for short-term trading or as a buffer may need to reconsider their strategy. The tax will be deducted at source by the ISA provider, meaning savers will see a reduced interest payment. HMRC has stated that the tax will apply to interest earned from April 2027 onwards, giving savers time to adjust their portfolios.
Reactions from the Financial Industry
The announcement has drawn criticism from some financial advisors, who argue that it undermines the simplicity of ISAs. "ISAs were designed to be simple and tax-efficient," said Mark Thompson, a financial planner at AJ Bell. "This change adds complexity and reduces the incentive to save within these accounts." However, HMRC defends the move, stating that it closes a loophole that allowed cash to be held tax-free in investment accounts.
Next Steps for Savers
Savers are advised to review their ISA holdings and consider transferring cash to a cash ISA or other savings accounts that may still offer tax-free interest. The tax-free allowance for cash ISAs remains unchanged at £20,000 per year. Additionally, investors may want to invest their cash rather than leave it uninvested to avoid the tax.
