£42,000 take-home pay by period

How the tax on £42,000 is calculated

£42,000 sits entirely in the basic-rate band: everything above £12,570 is taxed at 20% and NI is 8%, so each extra pound you earn is taxed at 28%. You can earn another £8,270 before reaching the 40% higher rate.

£42k after tax: above the median, below the higher rate

£42,000 is £2,961 (8%) above the UK full-time median of £39,039. It gives you £33,760 a year after tax, £2,813.30 a month, and an effective rate of 19.6%. In England, Wales and Northern Ireland you have £8,270 of headroom before the 40% higher rate.

In Scotland the headroom is much smaller. The Scottish higher rate of 42% starts at £43,662, only £1,662 above this salary. A £2,000 pay rise to £44,000 adds £1,440 to take-home in England but £1,349 in Scotland. Already at £42k, Scottish taxpayers keep £85 a year less.

Student loans now take a meaningful slice. Plan 2 costs £1,135 a year (£94.58 a month), Plan 1 costs £1,359 and Plan 5 £1,530. Together with the 28% tax and NI rate, a Plan 2 graduate keeps only 63% of each extra pound. That is worth knowing when you weigh a pay rise against extra pension or holiday.

£42,000 after tax in Scotland

Scottish taxpayers pay Scottish income tax rates on earnings. On £42,000 that is £5,971 of income tax compared with £5,886 elsewhere in the UK, so take-home pay is £2,806.21 a month (£7.09 less than in England).

£42,000 after tax with a student loan

Student loans are repaid at 9% of earnings above each plan's threshold (6% for postgraduate loans).

£42,000 after tax with a pension

Auto-enrolment requires at least 5% from you and 3% from your employer on qualifying earnings (£6,240 to £50,270) — for you that is £1,788 and £1,073 a year. Salary sacrifice also saves National Insurance, so it costs less in take-home pay than relief at source.

With income tax thresholds frozen, the same salary pays the same tax and NI this year. A pay rise that only matches inflation therefore leaves you slightly worse off in real terms.

£42,000 after tax on different tax codes

Your tax code tells your employer how much tax-free pay to give you. A wrong code is the most common reason a payslip differs from the figures above — check yours on your payslip or in the HMRC app.

£42,000 pro rata: part-time take-home

Part-time jobs are often advertised at the full-time equivalent (FTE) salary. Because the Personal Allowance is not pro-rated, working fewer days lowers your tax by more than your pay.

What your tax band means on £42,000

• Savings: as a basic-rate taxpayer your Personal Savings Allowance is £1,000 of interest a year. ISAs stay tax-free whatever you earn.
• Dividends above the £500 allowance are taxed at 10.75% at your band.
• Capital gains above the £3,000 exemption are taxed at 18% up to your unused basic-rate band (£8,270) and 24% above it.
• Pension tax relief: 20% relief is added automatically — a £1,000 pension contribution costs you £800 (or less through salary sacrifice).
• Marriage Allowance: if your partner earns under £12,570 they can transfer £1,260 of allowance to you, cutting your tax by up to £252 a year.
• Child Benefit: you keep it all — the High Income Child Benefit Charge only starts at £60,000.
• Tax-Free Childcare and 30 hours: available while each parent’s adjusted net income stays at or below £100,000.

What £42,000 costs your employer
