Take-home pay on GBP 40,000
A worked example of take-home pay at GBP 40,000, a salary level where tax planning starts to matter and the gap between gross and net pay becomes a real factor in decisions.
## The full deduction breakdown
On a £40,000 salary in the 2025-26 tax year (England, Wales, or Northern Ireland):
| Deduction | Annual | Monthly | |-----------|--------|---------| | Gross salary | £40,000 | £3,333 | | Personal allowance | £12,570 | — | | Taxable income | £27,430 | — | | Income tax (20% on £27,430) | £5,486 | £457 | | Employee NI (8% on £27,430) | £2,194 | £183 | | Take-home pay | £32,320 | £2,693 |
Your effective combined rate (income tax plus NI) is approximately 19.2%. The gap between gross and take-home is £7,680 per year — about £640 per month.
What to notice at this salary level
£40,000 sits well within the basic-rate band (which runs to £50,270). All taxable income is charged at 20% — there is no higher-rate tax at this level. However, you are £10,270 below the higher-rate threshold, which starts to make pension planning worth considering.
A raise to £45,000 adds £5,000 gross but only £3,600 take-home (at the 28% marginal rate). This is often where people first notice that gross and net raises feel very different.
Scottish taxpayers pay more income tax at this salary due to Scotland's intermediate and higher rates applying differently. The approximate take-home difference is around £860 per year less than a comparable Rest of UK taxpayer.
With a Plan 2 student loan
If you have a Plan 2 student loan (threshold £27,295 for 2025-26):
| | Annual | Monthly | |---|--------|---------| | Plan 2 repayment (9% of £12,705) | £1,143 | £95 | | Take-home pay with Plan 2 | £31,177 | £2,598 |
Plan 2 reduces take-home by £95 per month. For comparison, Plan 1 (threshold £24,990) would cost (£40,000 − £24,990) × 9% = £1,351 per year (£113/month).
What a £3,000 salary sacrifice would do
If you directed £3,000 into your pension via salary sacrifice:
| | Without sacrifice | With £3,000 sacrifice | |---|------|------| | Gross taxable pay | £40,000 | £37,000 | | Taxable income | £27,430 | £24,430 | | Income tax (20%) | £5,486 | £4,886 | | Employee NI (8%) | £2,194 | £1,954 | | Take-home pay | £32,320 | £30,160 | | Take-home reduction | — | £2,160 | | Pension value gained | — | £3,000 |
The £3,000 pension contribution costs you £2,160 in take-home — a 28% discount. You receive £3,000 of pension growth for an effective outlay of £2,160.
If you have a Plan 2 student loan, reducing adjusted income from £40,000 to £37,000 also lowers the loan repayment from £1,143 to (£37,000 − £27,295) × 9% = £873 — an additional saving of £270 per year (£23/month).
