Find out exactly how much income tax and National Insurance you pay on your salary and what your monthly take-home pay is. Based on 2024/25 UK tax rates and thresholds. Includes student loan plan deductions.
Income tax in the UK is charged on earnings above the Personal Allowance of £12,570. Tax is calculated in bands — you only pay the higher rate on the portion of income that falls within that band, not on your entire salary.
Employees pay Class 1 National Insurance at 8% on earnings between £12,570 and £50,270, and 2% on earnings above £50,270. NI contributions fund the NHS, state pension and other benefits.
If your income exceeds £100,000 your Personal Allowance is reduced by £1 for every £2 over that threshold. At £125,140 or above the Personal Allowance is reduced to zero.
