Salary sacrifice, and why the National Insurance line moves
The 5% pension figures above assume the money is deducted from pay — the net pay or relief at source arrangement. Income tax falls, but National Insurance is still charged on the full £42,000. A salary sacrifice works differently: what you give up is pay itself, so both bases fall. Same 5%, two different answers:
| Arrangement | Pension | Income tax | National Insurance | Take-home |
|---|---|---|---|---|
| Deducted from pay (net pay / relief at source) | −£1,788 | −£5,528 | −£2,354 | £32,329 |
| Salary sacrifice | −£1,788 | −£5,528 | −£2,211 | £32,472 |
The gap is £143 a year at this salary — the employee National Insurance that is no longer charged on the sacrificed amount, plus the small effect on the personal allowance where it tapers. Two limits are not modelled here: sacrifice cannot take pay below the National Minimum Wage, and some schemes calculate pensionable pay on the post-sacrifice figure, which changes what the employer contributes. Ask payroll which arrangement you are actually on before using either column.
Which thresholds £42,000 sits between
UK deductions are not one smooth percentage — they switch at fixed points. This is where £42,000 falls, which explains the marginal rates you will see on a payslip at this level.
| Threshold | Level | Status at £42,000 | What it means here |
|---|---|---|---|
| Personal allowance and NI start | £12,570 | Above | Below this, no income tax and no NI |
| NI drops to 2% | £50,270 | Below | Not reached |
| Personal allowance starts shrinking | £100,000 | Below | Not reached |
| Personal allowance gone | £125,140 | Below | Not reached |

Nearby salaries in England, Wales & NI
Is £42,000 a good salary in England, Wales & NI?
That depends on household size, housing costs and pension, which this page cannot know. What it can say: at £42,000 you keep £2,813 a month before pension, and 19.6% of gross goes to income tax and National Insurance.
How much is that per week?
£649 a week after tax and NI, or £622 with the 5% pension included. UK payroll usually quotes monthly or weekly, never annual, so this is the figure to compare with rent.
What if I pay more into my pension?
Each extra 1% under a net pay arrangement cuts income tax at your marginal rate but leaves National Insurance untouched. At £42,000 your marginal income tax rate is 999%, so an extra £1,000 into the pension saves roughly £9,991 in tax and costs -£8,991 in take-home. Under salary sacrifice the National Insurance line falls as well — see the two-arrangement table below.
Does salary sacrifice save more than a normal pension deduction at £42,000?
Yes — by about £143 a year at this salary, all of it National Insurance. A pension deducted from pay reduces income tax only, because NI is still charged on the full gross; a salary sacrifice gives up pay itself, so the NI base falls too. Both arrangements are priced at the same 5% in the table further down this page.
