Where your money goes on £40,000
Your £40,000 gross salary is reduced by income tax and National Insurance
before it lands in your bank account. For the 2026/27 tax year (6 April
2026 to 5 April 2027), here's the precise breakdown:

Why these specific numbers?
The first £12,570 of your salary is your
Personal Allowance —
completely tax-free. The remaining £27,430 falls entirely within the 20% basic rate band (which runs from £12,571 up to £50,270), so every pound is taxed at the same rate. £40,000 is £10,270 below the higher-rate threshold — you pay basic-rate tax on everything.
National Insurance follows similar mechanics. You pay 8% on earnings between £12,570 and £50,270. On a £40,000 salary, that's 8% of £27,430 = £2,194.40.

| £55,000 | £9,432 | £3,111 | £42,457.40 | £3,538.12 | 77.2% |
The effective rate — the share of your gross salary you actually keep —
falls as you earn more, because higher portions of income are taxed at higher
rates. This is why a pay rise never feels as big in your bank account as it
does on paper.
£40,000 in Scotland — what's different?
Scotland uses a different income tax system with six bands (compared to
three in the rest of the UK). On the same £40,000 gross salary, a
Scottish taxpayer's bill looks like this:
Income tax (Scotland)Six-band system
£5,551.07
13.9%
National InsuranceSame UK-wide rate
£2,194.40
5.5%
Take-home (Scotland)
£32,254.53
80.6%
That's £65.07 less per year than a worker on the same £40,000 in England, Wales, or Northern Ireland. Scotland's bands and rates differ from rUK at almost every
level, so the gap depends heavily on your exact salary.

The pension salary sacrifice trick
Pension salary sacrifice reduces your tax and NI bill while still
putting money toward retirement. On £40,000, here's how different
contribution levels play out:
| Pension contribution |
Sacrifice (annual) |
Tax saved |
NI saved |
Take-home (year) |
Net cost |
| 0% (no pension) | £0 | £0 | £0 | £32,319.60 | £0 |
| 5% sacrifice | £2,000 | £400 | £160 | £30,879.60 | £1,440 |
| 10% sacrifice | £4,000 | £800 | £320 | £29,439.60 | £2,880 |
| 15% sacrifice | £6,000 | £1,200 | £480 | £27,999.60 | £4,320 |
Read the 5% row carefully: putting £2,000 into your pension
via salary sacrifice only reduces your take-home pay by
£1,440. The difference comes from tax and NI
you no longer pay. You're effectively getting a 28% boost on every
pound contributed — before any employer matching or investment growth.
The catch: the money is locked away until age 55 (rising to 57 from 2028),
and it counts toward your annual £60,000 pension allowance.
