UK Salary & Tax Calculator

Understanding UK Payroll and Tax System

The UK payroll system involves several components that determine your take-home pay. Understanding how gross pay becomes net pay helps you budget effectively and make informed financial decisions.

Gross vs. Net Pay

Gross Pay: Your total salary before any deductions

Net Pay (Take-Home Pay): The amount you actually receive after all deductions

The difference between gross and net pay consists of various taxes, National Insurance contributions, and potentially other deductions like pension contributions or student loan repayments.

UK Income Tax System

The UK operates a progressive tax system, meaning the more you earn, the higher percentage of tax you pay on additional income. This is designed to ensure those who can afford to pay more contribute more to public services.

Tax Bands for 2024/25 Tax Year:

• Personal Allowance: £0 - £12,570 (0% tax)
• Basic Rate: £12,571 - £50,270 (20% tax)
• Higher Rate: £50,271 - £125,140 (40% tax)
• Additional Rate: £125,141+ (45% tax)

Important Notes:

• Tax bands may be reduced if you earn over £100,000 (personal allowance reduction)
• Scotland has different tax rates for some bands
• Tax rates and bands are reviewed annually in the Budget
