1. UK Tax Calculation Explained

In the UK, taxes on salary consist of Income Tax and National Insurance contributions. The amount you pay depends on your income level and is calculated using progressive tax bands.

2. How the Calculator Works

The calculator uses the current UK tax bands:

Income Tax Bands (2023/24):

• 0% on income up to £12,570 (Personal Allowance)
• 20% on income between £12,571 to £50,270 (Basic Rate)
• 40% on income between £50,271 to £125,140 (Higher Rate)
• 45% on income above £125,140 (Additional Rate)

National Insurance Bands (2023/24):

• 0% on income up to £12,570
• 12% on income between £12,571 to £50,270
• 2% on income above £50,270

3. Understanding Tax Bands

Details: The UK uses a progressive tax system, meaning you only pay the higher rate on the portion of your income that falls into that band, not your entire income.

4. Using the Calculator

Tips: Enter your gross annual salary before any deductions. The calculator will show your Income Tax, National Insurance, total tax, and net salary.
