1. What is the Interest Savings Tax Calculator?

The Interest 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.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Tax = \max(0, Interest - PSA) \times Tax\_Rate \]

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, then applies your marginal tax rate to that amount.

3. Importance of Savings Tax Calculation

Details: Understanding your tax liability on savings interest helps with financial planning, ensures you set aside appropriate funds for tax payments, and helps optimize your savings strategy across different account types.

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)

Q1: What is the Personal Savings Allowance?
A: The PSA is the amount of savings interest you can earn each tax year without paying tax. It varies based on your income tax band.

Q2: Who qualifies for the full £1,000 PSA?
A: Basic rate taxpayers (earning up to £50,270 in England) receive a £1,000 allowance. Higher rate taxpayers (£50,271-£125,140) receive £500. Additional rate taxpayers (over £125,140) receive no allowance.

Q3: Are all savings accounts taxable?
A: Most savings accounts generate taxable interest, but ISAs (Individual Savings Accounts) are tax-free regardless of the amount saved or interest earned.

Q4: How is savings tax collected?
A: For most people, savings tax is collected through self-assessment or through your tax code if you're employed. Banks don't deduct tax at source for personal savings.

Q5: What if I have multiple savings accounts?
A: You must add together interest from all taxable savings accounts to calculate your total interest for tax purposes.
