Tax on Savings Interest Set to Increase Significantly in 2027

The UK government has announced a substantial increase in the tax levied on savings interest, with rates set to rise by four percentage points from April 2027. This change, confirmed after an initial two-percentage-point hike was planned, will mean that interest earned above the personal savings allowance will be taxed at 24%, 44%, and 49% for basic, higher, and additional rate taxpayers, respectively. Currently, these rates stand at 20%, 40%, and 45%.

This adjustment comes at a time when interest rates on cash savings accounts are at multi-year highs, with top fixed-rate bonds exceeding 5%. This confluence of rising rates and increased taxation makes it easier for savers to exceed their tax-free personal savings allowance.

Personal Savings Allowance and Tax Implications

The Personal Savings Allowance provides a tax-free threshold for interest earned on savings. Basic rate taxpayers, earning between £12,571 and £50,270, 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 a 4.5% savings rate, basic rate taxpayers would begin paying tax on savings pots exceeding approximately £22,220. For higher rate taxpayers, this threshold drops to around £11,110.

The Growing Importance of ISAs

In light of these tax changes, utilizing Individual Savings Accounts (ISAs) becomes increasingly crucial. ISAs offer a £20,000 annual tax-free allowance, meaning any interest or returns earned within an ISA are not subject to the upcoming tax increases. The government has confirmed that the cash ISA allowance will not be reduced to £12,000 for those under 65 from April 2027.

Choosing the Right ISA

For those who may need access to their funds, easy-access cash ISAs are a primary option. While some accounts offer attractive introductory bonus rates, it is important to consider the underlying rate after the bonus period concludes. For accounts without a bonus, rates are currently around 4.52%.

Fixed-rate ISAs can offer higher interest rates for those willing to lock away their money for a set period, such as one or two years. However, these accounts often come with penalties for early withdrawal, making them suitable only for funds that are not needed for emergencies.

For longer-term savings, typically five years or more, a stocks and shares ISA may be considered. While subject to market fluctuations, these accounts offer the potential for greater long-term growth and can outpace inflation.

Other Tax-Efficient Savings Options

Beyond ISAs, other avenues exist for tax-efficient saving. Premium Bonds, with an annual prize rate of 4.35%, offer the chance to win tax-free prizes ranging from £25 to £1 million each month, with limits of £25 to £50,000. Pensions also provide significant tax efficiency, with tax relief on contributions and no capital gains or dividend tax on investments within the pension. However, access to these funds is typically restricted until age 55, rising to 57 in April 2028.
