How Much Savings Interest Is Tax Free in the UK?

You're not alone if you've ever pondered how much interest you can earn before it's subject to taxes. Why it's important now: The amount you can earn before paying taxes hasn't changed, but savings interest rates have increased recently. Consequently, an increasing number of savers are inadvertently surpassing those thresholds and encountering unexpected tax obligations. In the absence of appropriate awareness and tax planning, this situation is particularly worrisome.

A clearer guide: Every tax year, you can take advantage of multiple layers of tax-free savings allowance in the UK. The personal allowance, which is £12,570, is the first layer, and if your other income is low, you may be able to add a starting rate on savings of up to £5,000. Additionally, you receive a personal savings allowance, which is £500 for higher-rate taxpayers and £1,000 for basic-rate taxpayers. That could result in earning up to £18,570 in tax-free savings interest for those with extremely low incomes.

However, our meager interest income begins to exceed those allowance caps as interest rates rise. According to HMRC data, this change may affect over two million savers. To prevent unforeseen taxes, it is essential to comprehend your allowances, such as the £1,000 PSA or additional starting rate.

Why this matters for you: It can be difficult to understand these rules on your own, especially when figuring out how much of your interest each allowance covers. Working with tax accountants in Bolton can provide much-needed solace and clarity in this situation. To ensure you keep more of your earnings, a professional advisor will help you understand your overall income picture, walk you through the allowances, and make sure you aren't paying unnecessary taxes on savings.

UK Tax-Free Interest Allowances 2025–26

Each tax year (6 April–5 April) UK savers benefit from three key allowances:

1. Personal Allowance – up to £12,570 total income, including wages, pensions, and savings interest, is tax-free 
2. Starting Rate for Savings – up to £5,000 interest tax-free if non-savings income is below £17,570 
3. Personal Savings Allowance (PSA) –
• Basic-rate (20%) taxpayers: £1,000 
• Higher-rate (40%) taxpayers: £500
• Additional rate (45%+): no allowance

These allowances mean some savers could enjoy up to £18,570 of tax-free interest income—if carefully managed.

Why This Matters Now

Many basic-rate savers are now in taxable territory as a result of rising savings rates and frozen allowances. More than two million savers are now required to pay taxes on interest that was previously exempt. It pays to be informed because "fiscal drag" is raising tax obligations.

What You Should Do

• Track all interest payments across accounts (including cash, bonds, peer-to-peer platforms).
• Check your non-savings income to assess eligibility for the starting rate.
• Use tax wrappers wisely: ISAs shelter interest completely.
• Monitor your tax code—HMRC will adjust PAYE automatically, but delays can cost you.
• File a Self-Assessment return if savings interest exceeds £10,000.
• Consult with tax accountants in bolton to navigate allowances, minimise tax, and explore tax-efficient strategies like pension contributions or cash ISAs.

Final Thoughts

Up until certain thresholds, the majority of savers benefit from tax-free interest; however, due to complicated regulations and growing rates, many now unintentionally cross those lines. If non-savings income is carefully managed, the combined allowances can allow up to £18,570 in tax-free interest. To guard your savings against unexpected tax, use tax-efficient accounts and seek professional input from tax accountants in bolton.
