1. What is the UK Savings Interest Tax Calculator?

The UK Savings Interest 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.

2. How Does the Calculator Work?

The calculator uses the UK savings interest tax formula:

\[ Tax = \max(0, \text{interest} - \text{PSA}) \times \text{tax\_rate} \]

Where:

\( interest \) — Total savings interest earned (GBP)
\( PSA \) — Personal Savings Allowance: £1,000 (basic rate), £500 (higher rate), £0 (additional rate)
\( tax\_rate \) — Marginal tax rate: 20% (basic), 40% (higher), 45% (additional)

Explanation: The calculation determines how much of your savings interest exceeds your Personal Savings Allowance and applies your marginal tax rate to that amount.

3. Importance of Tax Calculation

Details: Accurately calculating tax on savings interest helps with financial planning, ensures compliance with HMRC regulations, and prevents unexpected tax bills.

4. Using the Calculator

Tips: Enter your total savings interest in GBP and select your marginal tax rate. The calculator will automatically determine your Personal Savings Allowance and calculate the tax due.

5. Frequently Asked Questions (FAQ)

Q5: Are there any exceptions to this tax?
A: Yes, ISAs (Individual Savings Accounts) are tax-free, and the first £5,000 of interest is tax-free for those with low income (starting rate for savings).
