£42,000 after tax: the breakdown
- Gross salary
- £42,000
- Personal Allowance
- £12,570
- Income Tax
- − £5,886.00
- National Insurance
- − £2,354.40
- Take-home pay
- £33,759.60
The first £12,570 is tax-free (your Personal Allowance). The rest is taxed at 20% basic rate (40% higher rate above £50,270), and employee National Insurance is 8% between £12,570 and £50,270, then 2% above. In Scotland the take-home on £42,000 is about £33,675 a year.
Where £42,000 sits
£42,000 a year is above the UK median full-time salary of about £37,430 (ONS), so a full-time worker on £42,000 earns more than roughly half the country. All of £42,000 falls within the 20% basic-rate band, so none of it is taxed at the higher 40% rate.
Your marginal tax rate, and what a pay rise is worth
On £42,000, the next pound you earn is taxed at about 28.0% (20% Income Tax plus 8% National Insurance). So a £1,000 pay rise to £43,000 would add only about £720 to your take-home. It is worth checking whether paying more into a workplace or personal pension at this income makes sense: pension contributions come out of your gross pay, so at a 28.0% marginal rate every £100 you contribute costs you only about £72 in take-home.
£42,000 after tax across the UK nations
Income Tax bands are the same in England, Wales and Northern Ireland, but Scotland sets its own. On £42,000 that is a difference of about £85 a year (less take-home in Scotland). National Insurance is identical across the whole UK.
