Comparing a stronger pension versus a higher salary

Scenario

You are negotiating a package and two structures are on offer:

Option A: £52,000 salary, standard employer pension
Option B: £49,000 salary + 10% employer pension contribution (£4,900/year into pension)

Option A pays £3,000 more in gross salary. Option B pays less cash but a significantly stronger pension. This example works through the after-tax numbers using 2025-26 rules to show which option delivers more real value — and under what circumstances.

Option A: £52,000 salary

At £52,000, a small portion of income falls into the higher-rate band (above £50,270):

Taxable income: £52,000 − £12,570 = £39,430
Basic rate: £37,700 × 20% = £7,540
Higher rate: (£39,430 − £37,700) × 40% = £1,730 × 40% = £692
Income tax: £8,232
Employee NI: £3,016 + (£52,000 − £50,270) × 2% = £3,016 + £35 = £3,051
Take-home: £40,717/year (£3,393/month)

Option B: £49,000 salary + 10% employer pension

At £49,000, all taxable income falls within the basic-rate band:

Taxable income: £49,000 − £12,570 = £36,430
Income tax: £36,430 × 20% = £7,286
Employee NI: £36,430 × 8% = £2,914
Take-home: £38,800/year (£3,233/month)

Employer pension contribution: 10% × £49,000 = £4,900/year paid directly into pension, with no income tax or NI deducted.

Side-by-side comparison

| | Option A (£52k) | Option B (£49k + 10% pension) | |---|---|---| | Gross salary | £52,000 | £49,000 | | Income tax | £8,232 | £7,286 | | Employee NI | £3,051 | £2,914 | | Take-home cash | £40,717 | £38,800 | | Monthly take-home | £3,393 | £3,233 | | Employer pension | — | £4,900 | | Total package value | £52,000 | £53,900 |

The cost-benefit of Option B

By taking Option B, you:

Give up £1,917/year in take-home cash (£160/month)
Receive £4,900/year in pension

For every £1 of foregone take-home, you gain £2.56 in pension. This is because employer pension contributions bypass income tax and NI entirely — the full £4,900 lands in your pension without any deduction.

The effective cost to you of £4,900 in pension is just £1,917 in cash. That is a better deal than any personal contribution could replicate, because personal contributions only recover the tax element (via relief at source), not the NI.

The higher-rate taper at £52,000

Option A is not purely a basic-rate calculation. At £52,000, £1,730 of income sits above the £50,270 higher-rate threshold and is taxed at 40% rather than 20%. Option B at £49,000 avoids this entirely — all income is within the basic-rate band. The marginal tax cost of the extra £3,000 in Option A is higher than it looks on the gross figures alone.

When Option A is better

You need the higher monthly cash flow immediately
You have other efficient pension routes (e.g. personal contributions, salary sacrifice in future years)
You are approaching the annual pension allowance and additional employer contributions create an unwanted tax charge

When Option B is better

You are in your 30s, 40s, or 50s and compound growth on the extra £4,900/year is significant over time
You can absorb the £160/month cash difference comfortably
You are a higher-rate or borderline taxpayer and want to keep more income below £50,270
