Frequently asked questions
How much tax do I pay on interest from £200,000 savings at 6%?
Interest earned: £12,000/year. Basic rate taxpayer (salary under £50,270): tax £2,200, net interest £9,800 — the first £1,000 is covered by your Personal Savings Allowance. Higher rate taxpayer (salary £50,270-£125,140): tax £4,600, net £7,400 (PSA is only £500). Additional rate taxpayer (salary over £125,140): no PSA, tax £5,400, net £6,600.
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 6%, what balance triggers a tax bill for a basic rate taxpayer?
A basic rate taxpayer's PSA covers £1,000 of interest. At 6% interest, this is used up at a balance of £16,667. With £200,000 at 6%, your interest is £12,000, so you exceed the PSA by £11,000, which is taxed at 20%, giving a bill of £2,200.
Should I put £200,000 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 6% on £200,000 you earn £12,000, 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.
