Why cutting your pay can actually make you richer.
Is a Pay Cut the Smartest Move You'll Make?
It sounds counterintuitive. Why would anyone voluntarily ask their employer to pay them less?
The answer lies in Salary Sacrifice, a government-approved arrangement where you agree to exchange part of your gross salary for a non-cash benefit—in this case, your pension contribution.
The Smart Way to Save
Because the contribution is made before tax and National Insurance (NI) are deducted, you pay less NI, and your employer often passes on their NI savings to you as well.
Why it matters
For most higher-rate taxpayers, this is the most efficient way to save. You get full tax relief immediately without claiming anything back.
Important: Watch Out
Salary sacrifice reduces your "contractual salary". This can affect borrowing (mortgages) or life cover multiples. Always check with your lender or employer handbook first.
The "Double Tax" Savings
When you pay into a pension from your net pay (after tax), you usually get Income Tax relief.
That's great.
But with Salary Sacrifice, you save on two taxes:
- Income Tax (20%, 40%, or 45%)
- National Insurance (8% for most employees)
Because your official "salary" is lower, you pay less NI. This is a saving you cannot get with a private SIPP or standard workplace schemes unless they are set up as Salary Sacrifice.
The £100 Example (2025/26)
Let's say you are a Basic Rate taxpayer and you decide to put £100 into your pension.
The Cost of £100 Pension
For every £100 that lands in your pension pot, your take-home pay only drops by £72
You instantly gain £28 in "free money" from the taxman.
Breaking it Down:
- Gross Pay Cut: £100
- Income Tax Saved (20%): £20
- National Insurance Saved (8%): £8 (Current rate)
- Employer NI Pass-back: Some generous employers also pass on their 13.8% NI saving to you!
Watch Out For...
While brilliant for most, Salary Sacrifice does lower your "official" salary. This could affect eligibility for:
- Mortgage multipliers (usually based on gross pay)
- Statutory Maternity Pay calculations
Always check with your HR department.
Guidance, not advice.
Tax rules (like the 2025/26 bands) can change and depend on your individual circumstances. Pension investments can go down as well as up.
