Need to Know: Income Tax and National Insurance

Income Tax

How much income tax you pay depends on how much of your income is above your personal allowance and how much of your income falls within each tax band.

  • 0% on the first £12,570 (personal allowance)

  • 20% on the next £37,000 (basic rate band)

  • 40% above £50,270 (Higher rate threshold)

  • 45% over £150,000 (Additional rate)

Marriage tax allowance allows you to transfer £1260 of your personal allowance to your spouse or civil partner if they earn more than you. To benefit, you must normally have an income below your personal allowance and can reduce your partners tax by up to £252.

If your income exceeds £100,000, your personal income tax allowance is gradually taken away from you. It is reduced by £1 for every £2 you earn after £100,000.

  • money you earn from employment
