Your payslip shows your gross pay, deductions, and net pay. In the UK, deductions are calculated through PAYE (Pay As You Earn), meaning your employer handles Income Tax and National Insurance automatically.

FAQs
What is the Personal Allowance?
The Personal Allowance is the amount you earn before paying income tax — £12,570 for 2024/25. It reduces by £1 for every £2 earned over £100,000.
What changed with National Insurance in 2024?
From January 2024, the main NI rate was cut from 12% to 10%, then to 8% from April 2024. This gives employees an average saving of £450/year.
How does pension affect my tax?
Contributions to a workplace pension reduce your gross taxable income. This means a £100 pension contribution only costs a 20% taxpayer £80 in real terms.
What does 'effective tax rate' mean?
Your effective tax rate is your total income tax paid divided by your gross income, expressed as a percentage. It's always lower than your marginal rate due to the personal allowance.
