£40,000 Salary After Tax — Exact Take-Home Pay UK 2026/27

A £40,000 salary sits comfortably above the UK median — but after income tax, National Insurance, student loan and pension, the amount that actually hits your account each month can be a surprise. Here’s the full breakdown for 2026/27.

The headline figures

On a £40,000 salary in 2026/27, using the standard 1257L tax code with no student loan or pension:

How income tax is calculated

Your personal allowance is £12,570 — earned completely tax-free. Your taxable income on £40,000 is £27,430. You pay 20% on that, giving an income tax bill of £5,486 a year — £457.17 a month.

At £40,000 you are firmly within the basic rate band. The higher rate of 40% does not apply until earnings exceed £50,270. Every pound of your salary is taxed at 20%, not 40%.

Important note: for earnings above £100,000, the personal allowance tapers away at £1 for every £2 earned over that threshold, disappearing entirely at £125,140 — creating an effective 60% marginal rate in that range.

Income tax bands 2026/27

England, Wales and Northern Ireland only. Scottish rates differ — the calculator covers these too.

National Insurance

Employees pay 8% National Insurance on earnings between £12,570 and £50,270. On £40,000 that’s £2,194.40 a year — £182.87 a month.

Student loan repayments

On £40,000 you’re comfortably above all main student loan thresholds, so repayments are active on every plan. You repay 9% on earnings above the threshold only.

With Plan 2 added, your take-home drops to £2,598.01 a month.

Pension contributions

A 5% auto-enrolment pension contribution on £40,000 is £166.67 a month. With both Plan 2 student loan and a 5% pension, your real take-home is approximately £2,431.35 a month.

Pension contributions through salary sacrifice also reduce your National Insurance liability — so the true cost to your take-home is slightly less than the headline figure.

What about the higher rate tax threshold?

At £40,000 you are £10,270 below the higher rate threshold of £50,270. All your income is taxed at 20% — not 40%. This is worth being clear about, as there is a common misconception that earning above £40,000 means paying 40% tax. It does not — the higher rate only applies to the portion of income above £50,270.

However, both thresholds are frozen until at least 2030/31. If your salary increases over the coming years, more of your pay will become taxable (fiscal drag) and eventually cross into the higher rate band without any formal tax rate rise.

What is a tax code?

The figures above use the standard 1257L tax code. If your code is different — due to a company car, second job, or an HMRC adjustment — your take-home will vary. Enter your exact code in the calculator to get a personalised figure.

Scottish Income Tax

If you live in Scotland, you pay Scottish Income Tax rates which differ from the rest of the UK. On £40,000 the Scottish intermediate rate of 21% applies to a portion of your earnings, meaning your tax bill is slightly higher than in England. Select Scotland in the calculator and it switches automatically.
