Variants on the basic case
+ 5% workplace pension (salary sacrifice)
Many workplaces use salary sacrifice for pension contributions. £40k earner sacrificing 5%:
| Component | Annual |
|---|---|
| Original gross | £40,000 |
| Pension contribution sacrifice | -£2,000 |
| New "gross" for PAYE | £38,000 |
| Income tax (20% on £25,430) | -£5,086 |
| Employee NI | -£2,034 |
| Net take-home | £30,880 |
| Pension pot growth this year | £2,000 |
| Real cost of contribution | £1,440 (saved £560 in tax+NI) |
Net effect: £2,000 added to pension at real cost £1,440 = 28% saving on every £1 contributed.
+ Plan 2 student loan (most graduates 2012-2023)
Plan 2: 9% on earnings over £28,470.
- £40,000 - £28,470 = £11,530 × 9% = £1,038.
- Take-home drops by £1,038/year (£86/month).
- New net: £31,282.
+ Plan 5 student loan (post-Aug 2023 starters)
Plan 5: 9% on earnings over £25,000.
- £40,000 - £25,000 = £15,000 × 9% = £1,350.
- New net: £30,970.
+ Plan 4 student loan (Scottish students)
Plan 4: 9% on earnings over £32,745.
- £40,000 - £32,745 = £7,255 × 9% = £653.
- New net: £31,667.
+ Marriage Allowance (partner transfers their unused £1,260 PA)
Marriage Allowance saves up to £252/year:
- Extended PA effectively £13,830.
- Income tax saving: £252.
- Net: £32,572.
Applies if your partner earns under £12,570 and you're a basic-rate taxpayer. See our Marriage Allowance post.
Scotland version
Scottish income tax on £40,000:
| Slice | Rate | Tax |
|---|---|---|
| Starter 19% × £2,827 | £537 | |
| Basic 20% × £12,094 | £2,419 | |
| Intermediate 21% × £12,509 | £2,627 | |
| Total Scottish IT | £5,583 | |

A Scottish £40k earner pays £97 more income tax than English — net difference about £8/month. Trivially small at this income level.
Wales and Northern Ireland version
Wales matches Westminster rates exactly. NI uses standard UK PAYE. Both produce identical results to England:
- Net take-home: £32,320/year.

Outside London, £40k is comfortable. Inside London, it's tight for a 1-bed without flatmates.
Path forward — every £5k pay rise
| Salary | Net take-home | Difference | Marginal rate next £1 |
|---|---|---|---|
| £35,000 | £28,550 | — | 28% |
| £40,000 | £32,320 | +£3,770 | 28% |
| £45,000 | £36,030 | +£3,710 | 28% |
| £50,000 | £39,520 | +£3,490 | 42% (higher rate) |
| £55,000 | £42,420 | +£2,900 | 42% |
Each £5k increment in the basic-rate band adds ~£3,500-£3,700 net. Above £50,270 it drops to ~£2,900 because of the higher-rate jump.
For £40k earners, every potential pay rise up to £50,270 is excellent value — 72% keep rate. Beyond that, the maths gets less attractive.
The first salary sacrifice habit
A £40k earner has roughly £10,000 of headroom before crossing into the higher-rate band. This is the ideal salary for building a workplace pension habit:
- 5-10% pension sacrifice doesn't touch your basic-rate position.
- 28% tax+NI saving on each £1 sacrificed (vs 42% in higher-rate band).
- 5% × £40k = £2,000/year contribution.
- Over 35 years at 5% real returns: ~£181,000 retirement pot.
- Real cost to take-home: ~£1,440/year = £120/month.
This is the cheapest opportunity to build long-term wealth in the UK system — and it gets used far too infrequently.
