Frequently asked questions

How much tax do I pay on interest from £10,000 savings at 5%?

Interest earned: £500/year. Basic rate taxpayer (salary under £50,270): tax £0, net interest £500 — the first £1,000 is covered by your Personal Savings Allowance. Higher rate taxpayer (salary £50,270-£125,140): tax £0, net £500 (PSA is only £500). Additional rate taxpayer (salary over £125,140): no PSA, tax £225, net £275.

What is the Personal Savings Allowance for 2025-26?

The PSA allows basic rate taxpayers to earn £1,000 in savings interest tax-free per year, and higher rate taxpayers £500. Additional rate taxpayers (over £125,140) have no PSA — all interest is taxed at 45%. ISA interest is always tax-free and does not count toward the PSA.

At 5%, what balance triggers a tax bill for a basic rate taxpayer?

A basic rate taxpayer's PSA covers £1,000 of interest. At 5% interest, this is used up at a balance of £20,000. With £10,000 at 5%, your interest is £500, so you are fully within the PSA and pay no tax on this interest.

Should I put £10,000 in an ISA or savings account?

A cash ISA pays tax-free interest regardless of your tax band. A regular savings account uses your PSA first (which fully covers your £500 interest at 5%). If you are a higher or additional rate taxpayer, an ISA is more valuable. Basic rate taxpayers may not benefit from an ISA if interest stays within their £1,000 PSA.
