Savings Tax Hikes Set to Increase Importance of ISAs

The United Kingdom government has announced a significant increase in the tax rate on savings interest, with a four percentage point hike scheduled to take effect in April 2027. This change means that interest earned above the personal savings allowance will be taxed at higher rates, impacting basic, higher, and additional rate taxpayers.

The current tax rates on savings interest are 20% for basic rate taxpayers, 40% for higher rate taxpayers, and 45% for additional rate taxpayers. From April 2027, these will rise to 24%, 44%, and 49% respectively. This adjustment comes at a time when interest rates on cash savings accounts are already at multi-year highs, with top fixed-rate bonds offering rates above 5%.

Personal Savings Allowance and Tax Implications

The Personal Savings Allowance provides a tax-free threshold for savings interest. Basic rate taxpayers, earning between £12,571 and £50,270 annually, have an allowance of £1,000. Higher rate taxpayers, earning between £50,271 and £125,140, have an allowance of £500. Additional rate taxpayers, earning £125,140 or more, do not receive a personal savings allowance and are taxed on all savings interest.

At current interest rates, it is becoming easier for savers to exceed these allowances. For example, a basic rate taxpayer with a £25,000 savings pot earning 4.5% interest would earn £1,125 annually. This would result in £30 of taxable interest. A higher rate taxpayer with the same savings pot and interest rate would face tax on £625 of interest, amounting to £275.

The Role of ISAs

Individual Savings Accounts (ISAs) offer a tax-free wrapper for savings and investments. Individuals are permitted a £20,000 annual allowance for ISAs, which can be allocated between cash and stocks and shares ISAs. Any interest or returns generated within an ISA are not subject to the upcoming tax increases.

In a move that has been welcomed by savers, the government has confirmed that the cash ISA allowance will not be reduced to £12,000 for individuals under 65 from April 2027, as had been previously suggested. This ensures that the full £20,000 allowance remains available for tax-free cash savings.

Choosing the Right ISA

For savers who may need access to their funds, an easy-access cash ISA is often recommended. Currently, some providers offer competitive rates, though it is important to note whether these include temporary bonus rates that will revert after a specified period. For instance, one provider offers a 4.87% rate that includes a 1.27% bonus for 12 months, with the underlying rate being 3.6%.

For those willing to lock away their money for a fixed term, higher rates are available. One-year fixed ISAs are currently offering up to 5%, while two-year fixed deals can provide around 5.10%. However, these fixed accounts typically impose penalties for early withdrawal, potentially leading to the loss of some or all accrued interest. Therefore, they are best suited for funds that are not needed for emergencies.

Stocks and Shares ISAs and Other Options

If money is not expected to be needed for at least five years, a stocks and shares ISA can be considered. Investing over a longer time horizon allows for the potential to ride out short-term market fluctuations and offers a greater possibility of outperforming inflation compared to cash savings. The long-term growth potential of investments can also help to mitigate the impact of taxes.

Beyond ISAs, other options for shielding savings from tax include Premium Bonds, which offer tax-free prizes. Individuals can invest between £25 and £50,000, with a current annual prize fund rate of 4.35%. Additionally, pension contributions offer significant tax efficiency, with tax relief on contributions and no capital gains or dividend tax on investments within a pension. However, access to pension funds is restricted until age 55 (rising to 57 in April 2028).
