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.
