What is National Insurance (NI)?
National Insurance contributions are deducted from your pay if you earn above the lower earnings limit. For 2024/25, employees pay 8% NI on earnings between £12,570–£50,270 and 2% above £50,270.
What tax code should I use?
Most people in the UK have the tax code 1257L for 2024/25, which gives a personal allowance of £12,570. Your tax code is shown on your payslip or in your HMRC personal tax account.
Does pension reduce my tax?
