Save National Insurance with Salary Sacrifice pension

Employers can save over £500 annually in NI per employee by setting up their workplace pension as salary sacrifice. The amount of savings depends on income banding and how much employees are earning.

Pension contributions are relevant for your NI bill because there are several different types of workplace pensions and they affect income that is considered NI taxable differently.

However, some pension schemes reduce income subject to National Insurance, and therefore reduce NI contributions.

How much National Insurance can I save using Salary Sacrifice?

By implementing a salary sacrifice scheme, an organisation with around 200 employees and an average income of £50,000 could make savings on their NIC of up to £129,000.

The following table shows how much you and your employees could save by implementing a salary sacrifice scheme, if your scheme is contributing to unbanded earnings.

If you are applying the pensionable earnings rule in your scheme, the amount of possible savings is lower for incomes that are higher than the qualifying earnings threshold of £50,270.

A brief overview of workplace pension

The amount that employers and their employees pay into their pension depends on the workplace pension scheme and whether they were automatically enrolled or opted in. Since April 2019, the minimum employer pension contribution is 3% and the employee pension contribution is 5%.

However, it depends on the workplace scheme that the employer has chosen. If an employee has voluntarily enrolled in a workplace pension and they earn more than £520 a month, £120 a week or £480 over 4 weeks, then their employer is required to contribute the minimum amount.

Relief at source

Relief at source is a method of claiming tax relief on pension contributions. Individuals pay into their pension scheme and then their provider claims basic rate tax relief from HMRC and puts the amount reclaimed into that person’s fund. This applies to individuals who do and don’t pay tax and is beneficial for those earning less than £50,000 per year.

Net pay

Net pay is the alternative method to account for PAYE savings on pension contributions, in which the gross income figure subject to PAYE is reduced by the pension contribution amount, which is beneficial for employees who earn above £50,000 per year.

Impact on NI-able gross income

To find more about information about Relief at Source and the alternative Net Pay workplace pension read the employer’s guide to pension contributions.

However, it is important to note that that neither Relief at Source or Net Pay reduce the gross amount of earnings subject to National Insurance.

What is Salary Sacrifice?

Salary sacrifice, also known as ‘salary exchange’ or ‘smart pay’, is an effective way of saving on your national insurance contributions. It is an agreement to ‘reduce an employee’s entitlement to cash pay, usually in return for a non-cash benefit’ as defined by HMRC here.

Under a salary sacrifice agreement, employers pay their employees’ pension contributions directly. Pension contributions are deducted before tax and national insurance. The result is that employees’ net pay is the total amount less their pension contribution.

What are the advantages of Salary Sacrifice?

By paying into employees’ pensions directly, employers reduce the net pay that employees receive. The result is that employees make savings on their national insurance, as well as seeing an increase in their take-home pay. In addition, employees whose pension contributions usually benefit from the ‘Relief at Source’ scheme will see their tax relief much faster rather than having to wait for HMRC to process it at a later date.

From an employer’s perspective, salary sacrifice is equally beneficial because they also pay smaller national insurance contributions on their employees’ income. Employers are also able to reinvest their savings back into their business or top up their employees’ pensions.

How does Salary Sacrifice work?

To implement a salary sacrifice scheme in your workplace, you need to make and agree on relevant changes to your contracts of employment with your employees in which they confirm they are willing to ‘sacrifice’ a set portion of their salary. This can also be applied to one-time items such as bonuses.

Salary sacrifice makes no difference to the amount that is paid into the employee’s pension. It only changes at which point and how it is deducted from their salary.

Things to consider about Salary Sacrifice

  • Employers must always ensure that salary sacrifice arrangements do not reduce an employee’s earnings below National Minimum Wage.
  • Employees may find that they lose entitlement to earnings-related benefits like Maternity Allowance or Additional State Pension
  • Salary sacrifice can also impact the amount of statutory pay that an employee is eligible for
  • A reduced take-home pay may impact an employee’s ability to borrow money (such as trying to take out a mortgage)
  • For some employees earning above a certain threshold, salary sacrifice can be counterintuitive.
  • If HMRC deems a salary sacrifice agreement invalid, it will consider the amount ‘sacrificed’ as earnings and therefore taxable (and also subject to national insurance levies).

How to implement a Salary Sacrifice pension

Establishing a salary sacrifice scheme, though an effective way of saving on you and your employees’ NI liability, can be labour-intensive to begin with. It’s essential to ensure that your agreements are valid and legally compliant. That’s why many businesses turn to expert advisors such as Mintago who specialise in reducing NI costs.

Here are the steps that you’ll need take to roll out your salary sacrifice scheme:

  • You must ensure to meet all HMRC’s prerequisites for a valid salary sacrifice agreement: You must make the relevant changes to your employment contract and agree on these changes with your employee. The amendments must explicitly outline the amount of pay to be sacrificed and the benefit the employee will receive in return The salary sacrifice can only apply to future earnings (cannot be applied retrospectively).
  • You’ll need to consider whether you’ll be making blanket changes to your employment contracts or operating an ‘opt-in, opt-out’ system. Compliance issues and implementation of the salary sacrifice scheme may differ depending on the chosen format.
  • You’ll need to decide how you’ll use your NI savings, whether for reinvesting in your business or generously adding to your employees’ pension pots.
  • You may want to make time for a ‘consultation’, allowing time to communicate with your employees, explain why a salary sacrifice is beneficial and outline the proposed changes.
  • If operating an ‘opt-in, opt-out’ scheme, you’ll need to provide two separate pension schemes or have the capability to segment your workforce to accommodate those enrolled in the sacrifice scheme and those who are not.

Make use of your annual employment allowance

There’s one more way to save on National Insurance: employment allowance. If your total NI contribution was under £100,000 in the last tax year, your business may be eligible for an employment allowance that reduces your class 1 NI contributions by up to a maximum of £5,000 for the tax year.

Modern payroll software such as Zelt makes it easy to apply for employment allowance. All you need to do is submit an Employment Payment Summary (EPS) to HMRC directly through your platform.

Implement salary sacrifice seamlessly with Zelt

With the 22/23 National Insurance hike increasing NICs by 1.25%, it’s no surprise employers are looking for ways to reduce how much they and their employees owe. Salary sacrifice is a legitimate and legal way to simultaneously reduce National Insurance liability, increase employee take-home pay, and make substantial savings for the business.

Modern enterprise software like Zelt makes the roll-out of salary sacrifice schemes easy. But salary sacrifice isn’t solely a payroll matter, it crosses over into HR and pensions too, as employee contracts need to be changed, policies made available and employee must have the option to change their contributions and revert their decision at any time.

For this reason, employer are advised to look for a modern employee management software, like Zelt, that unifies HR, payroll and pension, and empowers employees to opt in or out, access transparent information about your salary sacrifice schemes, and ultimately make their own decisions – which, in turn, improves the employee experience.

Finally, your workspace software should be agile and able to accommodate your particular needs. When it comes to salary sacrifice, the ability to roll out different payment and ‘sacrifice’ schemes for different employees is essential. And if your software isn’t up to the task, you may find yourself with a substantial administrative load.

FAQs about saving on national insurance

Can I save on NI with pension contributions?

As we’ve seen, for most employees, opting in to a salary sacrifice arrangement will result in reduced national insurance contributions.

Is salary sacrifice worth it?

Salary sacrifice arrangements result in higher take-home pay for employees and reduced NI contributions for employers. From this perspective, it’s definitely worth it.

Is there a limit on salary sacrifice in the UK?

Though there’s technically no limit on how much an employee can choose to sacrifice, their income can never dip below the national living wage. In addition, there is a cap on how much you can contribute to your pension tax free per year, so it only makes sense to ‘sacrifice’ up to £40,000 (the current limit) every year anyway.
