1. What is the UK Tax Calculation?

The UK tax calculation determines the amount of income tax payable based on gross annual income using the UK's progressive tax system with different tax bands and rates.

2. How Does the Calculator Work?

The calculator uses the UK tax formula:

Where:

• \( income \) — Gross annual income (GBP)
• 12570 — Personal allowance threshold
• 37700 — Basic rate band limit
• 50270 — Higher rate threshold
• 74870 — Additional rate threshold
• 0.20 — Basic tax rate (20%)
• 0.40 — Higher tax rate (40%)
• 0.45 — Additional tax rate (45%)

Explanation: The formula calculates tax in three bands: basic rate (20% on income up to £37,700), higher rate (40% on income up to £74,870), and additional rate (45% on income above £125,140).

3. Importance of Tax Calculation
