All of your taxable income (£5,430) falls in the 20% basic-rate band, so you are a basic-rate taxpayer. You still have £32,270 of basic-rate band left before the 40% higher rate starts at £50,270.
Income Tax: £1,086
The first £12,570 is your tax-free Personal Allowance. The remaining £5,430 is taxed in bands:
| Band | Income in band | Tax |
|---|---|---|
| Personal Allowance (0%) | £12,570 | £0 |
| Basic rate (20%) | £5,430 | £1,086 |
| Total Income Tax | £5,430 taxable | £1,086 |
National Insurance: £434
Employees pay Class 1 National Insurance at 8% on earnings between £12,570 and £50,270 and 2% above that. On £18,000 that is 8% of £5,430.
Your marginal rate
If you earned an extra £1,000, you would keep about £720 of it, because your combined marginal rate of tax and NI is 28%.
£18,000 with a 5% pension (salary sacrifice)
Paying 5% of your salary (£900 a year) into a workplace pension through salary sacrifice lowers both your tax and NI. Your take-home pay would be £15,832 a year (£1,319 a month). That is £648 less in your pocket, but £900 goes into your pension, so you are £252 better off overall once tax relief is counted. Your employer may add more on top.
