How a £18,000 salary is taxed in 2026/27
Income tax. After the £12,570 personal allowance, £5,430 is taxable: £5,430 at 20%. That is £1,086 of income tax — an effective rate of 6.0% on the full salary even though your top rate is 20%.
National Insurance. Employees pay Class 1 NI of 8% on earnings between £12,570 and £50,270 and 2% above, so £18,000 costs £434 a year (£36 a month). NI is the same in Scotland.
Scotland. Scottish taxpayers use six bands (19%, 20%, 21%, 42%, 45% and 48%). At £18,000 your top Scottish band is the basic rate (20%) and you pay £1,046 income tax — £40 less than in the rest of the UK, leaving £16,519 a year.
Student loan and pension. At £18,000 you are below the £29,385 Plan 2 threshold, so a Plan 2 student loan takes nothing. A 5% workplace pension (£900) costs you only £720 in take-home under a net pay arrangement because it comes out before income tax, or £648 through salary sacrifice, which also saves NI.
A raise from here. A £1,000 pay rise to £19,000 adds £720 to take-home in England, Wales and NI — you keep 72p of each extra pound (marginal deduction rate 28%; 28% in Scotland).
