What Is Salary Sacrifice for Pensions?

Salary sacrifice is a tax-efficient arrangement where you agree to reduce your gross salary in exchange for your employer making increased pension contributions on your behalf. Because the payment is made before Income Tax and National Insurance are calculated, both you and your employer save on NI contributions – making it one of the most powerful ways to boost your pension savings without any extra cost to your employer.

For a higher rate taxpayer earning £60,000 who sacrifices £5,000 into their pension, the total saving in Income Tax and NI is around £3,100. If the employer passes on their 13.8% NI saving (£690), the pension receives £5,690 but the employee’s take-home pay drops by only £2,590. That is an effective return of over 119% before any investment growth.

Key aspects of salary sacrifice for pensions that you need to understand include:

  • NI savings – employees save 8% and employers save 13.8% NI on the sacrificed amount. Many employers pass on part or all of their saving as an additional pension contribution.
  • Effect on take-home pay – your salary is permanently reduced by the sacrifice amount. This may affect your mortgage borrowing capacity, statutory benefits, and any salary-linked benefits.
  • Minimum wage rules – your reduced salary cannot fall below the National Minimum Wage. If the sacrifice would bring you below this threshold, it must be reduced accordingly.
  • Benefit implications – salary sacrifice reduces your official salary, which can affect entitlement to statutory maternity pay, statutory sick pay, and other income-related benefits.
  • Student loan repayments – because sacrifice reduces your gross salary, it can reduce or eliminate student loan repayments, saving additional money each month.
  • Contractual commitment – once agreed, salary sacrifice typically cannot be changed until the next review window unless there is a “life event” such as marriage, divorce, or redundancy.
Key fact: According to HMRC, salary sacrifice pension arrangements save UK employees an estimated £1.5 billion per year in National Insurance contributions alone. Despite this, many employees eligible for salary sacrifice do not use it because they do not understand the benefits or their employer has not offered it.

Some employers offer a “smart pension” scheme that combines salary sacrifice with standard contributions to maintain benefit levels.
Who Is It For?

Who Benefits from Salary Sacrifice Advice?

Salary sacrifice is not suitable for everyone. An adviser can help you determine whether it is right for your circumstances.

💰

Higher Rate Taxpayers

If you earn above £50,270, salary sacrifice saves you 40% tax and 8% NI on contributions. Combined with employer NI pass-through, this can be worth thousands more than standard contributions each year.

🏢

Employees With Matching

If your employer matches contributions and also offers salary sacrifice, combining both maximises the value. Some employers enhance matching when salary sacrifice saves them NI.

Student Loan Holders

Salary sacrifice reduces your gross salary, potentially bringing it below student loan repayment thresholds. On Plan 2, this saves 9% on earnings above £27,295.

Parents Approaching Maternity

Salary sacrifice reduces your qualifying earnings for Statutory Maternity Pay. If you are planning a family, you may want to pause sacrifice before your qualifying period begins.

Mortgage Applicants

Because salary sacrifice reduces your gross salary on paper, it can affect how much lenders will offer. An adviser can help you decide whether to pause sacrifice during a mortgage application.

Bonus Sacrifice

Sacrificing annual bonuses into your pension is extremely tax-efficient, especially for higher rate taxpayers. A £10,000 bonus sacrificed could be worth £15,180 in pension versus £5,900 net take-home.

“NI savings added £2,400 per year”

Switching to salary sacrifice on my £65,000 salary saves me £960 in NI per year, and my employer passes on their £1,380 NI saving too. That is £2,340 extra going into my pension for zero cost to me.

“Bonus sacrifice was transformative”

I sacrificed my £12,000 bonus and received £13,656 in my pension (with employer NI pass-through) instead of £6,960 net in my bank. The adviser showed me the maths and it was an obvious choice.

“Student loan savings were a bonus”

Salary sacrifice reduced my gross pay below the Plan 2 threshold, saving me £3,200 in student loan repayments per year on top of the pension benefits. I wish I had known about this years ago.

★★★★★
“Employer enhanced their match”

When I asked about salary sacrifice, my employer agreed to match at a higher rate because they save NI too. Instead of 5% match, they now put in 7%. The adviser helped me negotiate this.

“Mortgage timing was crucial”

The adviser warned me to pause salary sacrifice three months before my mortgage application. My certificated salary was £8,000 higher which made a real difference to the amount I could borrow.

“SMP implications were explained clearly”

I was about to start salary sacrifice but the adviser flagged that it would reduce my Statutory Maternity Pay. We delayed it until after my qualifying week, saving me over £2,000 in SMP.

Salary Sacrifice: Frequently Asked Questions

Salary sacrifice is an arrangement where you agree to a permanent reduction in your gross salary in exchange for your employer making additional pension contributions. Because the payment is made before tax and NI, both you and your employer save National Insurance contributions – typically 8% and 13.8% respectively.
A higher rate taxpayer sacrificing £5,000 saves roughly £2,000 in tax, £400 in employee NI, and potentially £690 from employer NI pass-through. That means £5,690 goes into the pension but take-home pay only drops by £2,590 – an effective boost of 119%.
Yes, but by less than you might expect. Because you save Income Tax and NI on the sacrificed amount, the net reduction in take-home pay is significantly less than the gross amount sacrificed. For a basic rate taxpayer, every £100 sacrificed only reduces take-home by about £68.
Most salary sacrifice agreements have fixed review periods, typically annually. You can usually only opt out early if you experience a qualifying “life event” such as marriage, divorce, redundancy, or a significant change in circumstances. Check your specific employer arrangement.
It can. Salary sacrifice reduces your gross salary, and some mortgage lenders use gross salary to calculate affordability. However, most lenders now understand salary sacrifice and may accept a letter from your employer confirming your pre-sacrifice salary. Timing sacrifice around applications may help.
Yes. Statutory Maternity Pay is based on your qualifying earnings, which are reduced by salary sacrifice. This could reduce your SMP by up to £2,500 over 39 weeks depending on the sacrifice amount. Consider pausing sacrifice before your SMP qualifying period (weeks 17-25 of pregnancy).
Employers save 13.8% NI on the sacrificed amount. Some pass all of this saving to employees as additional pension contributions, some pass part, and some retain it. Ask your HR department what your employer does. The best schemes pass on 100% of the saving.
Yes, many employers allow bonus sacrifice. This is particularly tax-efficient for higher rate taxpayers. A £10,000 bonus taken as salary nets roughly £5,900 after tax and NI. The same amount sacrificed into your pension provides up to £11,380 with employer NI pass-through.
Yes. Salary sacrifice reduces your gross salary below the student loan repayment threshold more quickly. For Plan 2 loans, the threshold is £27,295. If sacrifice brings your salary below this, you stop making repayments, saving 9% of the amount below the threshold.
Not exactly. With standard contributions, you pay from your net salary and receive tax relief. With salary sacrifice, your salary is reduced and your employer makes the contribution directly. The key difference is the NI saving – standard contributions do not save NI, but sacrifice does.
Your salary after sacrifice cannot fall below the National Minimum Wage (currently £11.44 per hour for over 21s). If the sacrifice would reduce your hourly rate below this level, the amount must be reduced or the arrangement cannot proceed.
Yes, provided your post-sacrifice salary remains above the National Minimum Wage. Part-time workers on lower salaries should be careful about the impact on state benefits and loan repayments. An adviser can calculate whether the NI savings outweigh any benefit reductions.
It depends on your employer scheme. Some death-in-service policies are calculated on your pre-sacrifice salary, others on post-sacrifice. Check your employee benefits documentation carefully, as a reduction in death-in-service cover could significantly affect your family protection.
Salary sacrifice contributions are typically paid into your workplace pension scheme, not a SIPP. However, some employers may be flexible. If you want to use a SIPP, you would normally make standard contributions and receive tax relief through the usual channels.
Speak to your HR or payroll department. Not all employers offer salary sacrifice, and those that do may have specific enrolment windows. You will need to sign an amendment to your employment contract. Your employer may also need to update their payroll system and pension provider details.
