The UK Savings Tax Calculator estimates the tax payable on savings interest based on your marginal tax rate and Personal Savings Allowance (PSA). It helps individuals understand their tax liability on interest earned from savings accounts.
The calculator uses the UK savings tax formula:
Where:
Explanation: The calculation determines how much of your savings interest exceeds your Personal Savings Allowance, then applies your marginal tax rate to that amount.
Details: Understanding your tax liability on savings interest helps with financial planning, ensures you set aside appropriate funds for tax payments, and helps avoid unexpected tax bills.
Tips: Enter your total savings interest in GBP, select your marginal tax rate based on your income tax band. The calculator will automatically determine your applicable Personal Savings Allowance and calculate the tax due.
Q1: What is the Personal Savings Allowance (PSA)?
A: The PSA is the amount of savings interest you can earn each tax year without paying tax. It's £1,000 for basic rate taxpayers, £500 for higher rate taxpayers, and £0 for additional rate taxpayers.
Q2: Do I need to declare savings interest?
A: You need to declare savings interest that exceeds your PSA. Basic rate taxpayers earning less than £1,000 and higher rate taxpayers earning less than £500 in savings interest typically don't need to declare it.
Q3: How is savings interest taxed?
A: Savings interest is taxed at your marginal income tax rate (20%, 40%, or 45%) on any amount above your Personal Savings Allowance.
Q4: Are there any tax-free savings options?
A: Yes, ISAs (Individual Savings Accounts) allow you to save up to £20,000 per tax year completely tax-free, with no tax on interest, dividends or capital gains.
Q5: What if I have multiple savings accounts?
A: You must add together interest from all your savings accounts (except ISAs) to calculate your total taxable interest for the tax year.
