Changes to Salary Sacrifice for pension benefits

The Chancellor announced in the November 2025 Budget that there will be changes to the rules on salary sacrifice for employer pension contributions. This may also be referred to as “salary exchange”, “bonus sacrifice” or “bonus exchange”.

What is salary sacrifice?

Salary sacrifice is an agreement between you and your employer, where you agree to give up some of your salary, in return for a non-cash benefit paid for by your employer – for example, pension contributions, workplace nurseries or childcare vouchers.

The non-cash benefit impacted by this change is an employer pension contribution.

Employer pension contributions are exempt from both employer and employee national insurance contributions (NICs). This means that if you give up some salary and put it into your pension instead (salary sacrifice), you save on your NICs. This means you could either take home more pay or boost your pension without reducing your take-home pay.

The % saved depends on the NICs rates you pay.

	% of sacrificed salary saved
Basic Rate Taxpayer	8%
Higher or Additional Rate Taxpayer	2%

What are the proposed changes?

From 6^th April 2029, both employee and employer NICs will apply to the amount of salary sacrifice for employer pension contributions more than £2,000 per year.

Does this mean employees can only sacrifice £2,000 per year for employee pension contributions?

No, employees can still sacrifice more than £2,000 for employer pension contributions, but both they and their employer will pay NICs on the amount above £2,000.

This is an important distinction, as salary sacrifice can result in some employees becoming eligible for means-tested benefits, such as child benefit or free childcare hours. This can also mean that they avoid losing their income tax personal allowance, which tapers to zero for those earning between £100,000 and £125,140 per year.

Salary sacrifice can mean that higher and additional rate taxpayers saving in Aviva workplace personal pensions do not need to claim additional income tax relief through an end of year tax return. Everyone using salary sacrifice automatically receives full pensions tax relief.

What about salary sacrifice for other benefits, such as electric cars?

How much is it going to cost me?

From 6 April 2029, you may pay more in employee National Insurance Contributions (NICs) if you sacrifice more than £2,000 of salary or bonus for employer pension contributions.

A single £2,000 annual threshold applies to all salary and bonus sacrificed in a tax year. With the current NIC rates, this means that:

If you are a basic rate taxpayer, you pay NICs at a rate of 8%.
If you are a higher or additional rate taxpayer, you pay NICs at a rate of 8% up to £50,270 per year (£4,189 per month) and at 2% on earnings above this.

The table below shows the extra NICs you would pay each year based on different salaries and sacrifice amounts. Figures assume 2025/26 NIC rates and thresholds remain unchanged.

Some employees choose to adjust the amount they sacrifice for employer pension contributions, so their take-home pay stays the same as before. This increases the amount paid into their pension by the employer, at no extra cost to the employee.

From 6^th April 2029, it will be this higher level of salary sacrifice that will be used to calculate any additional NICs due from both the employee and employer.

An example is shown below:

	No Salary Sacrifice	10% Sacrifice NICs saving taken as additional pay	Sacrifice adjusted to keep take home pay the same
Gross Salary	£50,000	£45,000	£44,444.44
Salary Sacrifice Amount	£0	£5,000	£5,555.56
Income Tax p.a.	£6,486	£6,486	£6,374.89
Employee NICs p.a.	£2,994.40	£2,594.40	£2,549.96
Employee Pension Contribution	£5,000	£0	£0
Net Annual Income	£35,519.60	£35,919.60	£35,519.60
Employer Pension Contribution	£0	£5,000	£5,555.56
Additional Take Home Pay 2025/26	£0	£400	£0
Additional Employee NICS 2029/30*	£0	£240	£284.44

*Assumes 2025/26 thresholds remain, as currently planned

If I reduce the amount I sacrifice for employer pension contributions to £2,000, will I avoid the NICs increase?

Can I change the amount I sacrifice for employer pension contributions?

The government has not introduced any new rules to prevent changes to salary sacrifice in the run up to 6^th April 2029, or after the new rules come in.

Unlike salary sacrifice for some other benefits, HMRC allows changes to salary sacrifice for employer pension contributions at any time.

You should be aware that employers may restrict when changes to salary sacrifice can be made for administrative reasons.

Before making any change to the amount you sacrifice for employer pension contributions, you should really think about:

Whether you can afford any change.
The impact any change could have on your pension income in retirement.
The impact that any change might have on means-tested benefits or the income tax you will pay.
