A £40,000 salary is about £32,320 a year after tax, which is roughly £2,693 a month or £622 a week.
That is for the 2026/27 tax year on the standard 1257L tax code, with no pension contributions and no student loan, in England, Wales or Northern Ireland. Scotland sets its own bands, so the figure there is different. Everything below shows the working, so you can see exactly where the money goes.

The working, step by step
Step 1: take off the personal allowance. The first £12,570 you earn carries no income tax. That leaves £27,430 of taxable income.
Step 2: apply income tax. The basic rate band runs from £12,570 up to £50,270, so all £27,430 sits inside it and is taxed at 20%.
£27,430 x 20% = £5,486
Step 3: apply National Insurance. Employees pay 8% on earnings between £12,570 and £50,270. That is the same £27,430.
£27,430 x 8% = £2,194
Step 4: what is left is yours.
£40,000 minus £5,486 minus £2,194 = £32,320
Your headline tax rate is 20%, but your effective income tax rate is only 13.7%, because the first £12,570 escapes tax completely. This is the bit people miss when they assume a pay rise will be swallowed.

What changes the number
A workplace pension. This is the biggest single factor and it usually works in your favour. Pay 5% into a pension and £2,000 goes into your pot, while your take-home falls by less than £2,000 because the contribution reduces the pay you are taxed on. Under salary sacrifice it also cuts your National Insurance, so the real cost is lower again. Our salary sacrifice guide walks through the numbers.
A student loan. On Plan 2 you repay 9% of everything above the threshold. On a £40,000 salary that is a meaningful monthly amount on top of tax and National Insurance, and it is not tax relief, it is a repayment.
Your tax code. 1257L is standard. A different code changes your tax-free allowance, and the usual causes are company benefits like a car or medical insurance, unpaid tax carried over from an earlier year, or the Marriage Allowance.
Living in Scotland. Scottish income tax has six bands rather than three. A £40,000 salary crosses the starter, basic and intermediate rates, which produces a slightly different result from the table above.
Bonuses and overtime. These are taxed, but the month they land can look far worse than the annual figure suggests, because PAYE is worked out cumulatively. If a payslip has surprised you, see why you paid more tax this month.
Is £40,000 a good salary in the UK?
It sits above the UK median for full-time work, so on a national view it is a decent salary rather than a high one. Two things matter more than the headline number.
The first is where you live. £40,000 stretches very differently in Manchester or Newcastle than it does in London, where housing takes a much larger share.
The second is your pension. Two people on £40,000 can be in quite different positions if one employer contributes 3% and the other contributes 10%. Total reward, not salary, is the number worth comparing when you are weighing up a job offer.
The £50,270 line worth knowing about
At £40,000 you have around £10,000 of headroom before you reach the higher rate threshold at £50,270. Above that, each extra pound is taxed at 40% instead of 20%, and National Insurance drops from 8% to 2%, so the combined marginal rate goes from 28% to 42%.
If you also claim Child Benefit, the High Income Child Benefit Charge starts at £60,000 and pushes your effective rate higher still. You can see exactly what your next pound costs on the marginal tax rate calculator.
Work out your own figure
The table above is the clean case. If you pay into a pension, have a student loan, live in Scotland, work part time or receive a bonus, the number moves.
