| From: | To: |
The UK Savings Interest Tax Calculator estimates the tax payable on savings interest based on your Personal Savings Allowance (PSA) and marginal tax rate. It helps UK taxpayers understand their tax liability on interest earned from savings accounts.
The calculator uses the UK tax formula:
Where:
Explanation: The calculation determines the taxable amount (interest above your PSA) and applies your marginal tax rate to calculate the tax due.
Details: Accurate tax calculation on savings interest is essential for proper tax planning, ensuring compliance with HMRC regulations, and avoiding underpayment or overpayment of taxes.
Tips: Enter your total savings interest in GBP, select your marginal tax rate (20% for basic rate, 40% for higher rate, 45% for additional rate), and input your Personal Savings Allowance. Standard PSA amounts are £1,000 for basic rate taxpayers, £500 for higher rate taxpayers, and £0 for additional rate taxpayers.
Q1: What is the Personal Savings Allowance (PSA)?
A: The PSA is the amount of savings interest you can earn each tax year that is tax-free. It's £1,000 for basic rate taxpayers, £500 for higher rate taxpayers, and £0 for additional rate taxpayers.
Q2: Do I need to pay tax on all my savings interest?
A: No, you only pay tax on savings interest that exceeds your Personal Savings Allowance for the tax year.
Q3: How is savings interest taxed for joint accounts?
A: For joint accounts, the interest is typically split equally between account holders, and each person uses their own PSA against their share of the interest.
Q4: What if my savings interest is below my PSA?
A: If your total savings interest is below your PSA, you won't owe any tax on that interest for the tax year.
Q5: Do I need to declare savings interest to HMRC?
A: If your total savings interest exceeds your PSA, you may need to declare it to HMRC through a self-assessment tax return or by informing them so they can adjust your tax code.
