Your personal savings allowance lets you earn interest on your savings without paying tax. If you're a basic rate taxpayer, you can currently earn up to £1,000 tax-free, while higher rate taxpayers can enjoy up to £500. Additional rate taxpayers do not have a PSA.
To maximise this allowance, see if you could benefit from putting your savings into an ISA. By doing this, you'll pay no UK income tax or capital gains tax on interest, regardless of your PSA.
ISAs can be a great way to boost your savings without worrying about tax limits (the annual ISA limit for 2025/26 tax year is £20,000). You can learn more about paying tax on your savings in our explainer.
Keep an eye on interest rates and think about spreading your savings across different accounts to get the best returns. Regularly reviewing your savings strategy means you can grow your money while staying within tax-free limits.
