Frequently asked questions
How much tax do I pay on interest from £75,000 savings at 3.5%?
Interest earned: £2,625/year. Basic rate taxpayer (salary under £50,270): tax £325, net interest £2,300 — the first £1,000 is covered by your Personal Savings Allowance. Higher rate taxpayer (salary £50,270-£125,140): tax £850, net £1,775 (PSA is only £500). Additional rate taxpayer (salary over £125,140): no PSA, tax £1,181, net £1,444.
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 3.5%, what balance triggers a tax bill for a basic rate taxpayer?
A basic rate taxpayer's PSA covers £1,000 of interest. At 3.5% interest, this is used up at a balance of £28,571. With £75,000 at 3.5%, your interest is £2,625, so you exceed the PSA by £1,625, which is taxed at 20%, giving a bill of £325.
Should I put £75,000 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 (but at 3.5% on £75,000 you earn £2,625, exceeding the basic rate PSA of £1,000). 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.
