Understand how salary sacrifice works, the potential benefits it can offer, and how Twelve Wealth Management can help you make informed, tax-efficient decisions.

What Is Salary Sacrifice?

Salary sacrifice is an arrangement where an employee agrees to reduce part of their gross salary in exchange for a non-cash benefit, most commonly increased pension contributions. Because the reduction is made before tax and National Insurance are calculated, it can improve tax efficiency for eligible employees while also reducing employer National Insurance costs when structured correctly.

In the UK, salary sacrifice arrangements must be documented properly, reflected in the employment contract, and must not reduce pay below National Minimum Wage thresholds. The exact outcome depends on earnings, the type of benefit provided, payroll setup, and the broader financial position of the employee or business owner.

How Salary Sacrifice Can Help Individuals

• Potentially increase pension contributions in a tax-efficient way.
• Reduce Income Tax and National Insurance on the sacrificed amount where applicable.
• Improve long-term retirement planning without necessarily reducing overall financial goals.
• Support wider planning opportunities, such as managing adjusted income and reviewing personal cash flow.

It is important to review the wider impact before making changes. Salary sacrifice can affect borrowing assessments, statutory payments, and other salary-linked benefits, so any arrangement should be considered alongside your full financial plan.

What Is the Process for Salary Sacrifice?

The process for salary sacrifice is usually straightforward, but it needs to be set up carefully to make sure it is effective, compliant, and suitable for everyone involved. In most cases, it follows a clear sequence of agreement, implementation, and ongoing review.

1. Review whether salary sacrifice is appropriate based on earnings, benefits, and wider financial circumstances.
2. Agree the arrangement between employer and employee before it takes effect.
3. Update the employment contract so the reduced salary and corresponding benefit are clearly documented.
4. Adjust payroll so tax and National Insurance are calculated on the new lower salary.
5. Put the chosen benefit in place, such as increased employer pension contributions.
6. Monitor the arrangement over time to ensure it remains suitable, compliant, and aligned with changing circumstances.

Because salary sacrifice involves a contractual change rather than a simple deduction, it is important that arrangements are documented properly and checked against issues such as National Minimum Wage limits, statutory benefits, and the wider tax position.

Example

Here is a simple example to show how salary sacrifice can work in practice. The figures are illustrative only, but they help demonstrate the structure of the arrangement and the potential outcome.

An employee earning £50,000 a year agrees to sacrifice £5,000 of salary into their pension. Their contractual salary is reduced to £45,000, and the employer pays the £5,000 into the pension instead as an employer contribution.

• How it works: The employee gives up £5,000 of gross salary before tax and National Insurance are calculated. Tax relief is received at source
• What happens next: The employer redirects that £5,000 into the employee’s pension as an employer contribution.
• The result: The employee will pay less Income Tax and National Insurance than they would have done on that amount, while still increasing pension funding.
  • £2100 per annum Income Tax and National Insurance Saving
  • £750 per annum employer National Insurance Saving
  • Effective Saving rate – 57%. (£2,850 per annum)
  • Therefore - £2,150 net cost to add £5,000 to your Pension
• Potential employer benefit: The employer may also save National Insurance on the sacrificed amount, depending on how the arrangement is structured. As an umbrella contractor you pay the employers NI so you get a further saving on Tax via salary sacrifice pension payments.

The exact result will depend on earnings, tax position, payroll arrangements, and whether salary sacrifice is suitable for the individual or business. This is why personalised advice and careful implementation are so important.

How much is the annual allowance?

The annual allowance from April 2020 is £60,000 based on adjusted income of £240,000 or below, but this tapers down to £10,000 where adjusted income is between £240,000 and £300,000, and then reduces to £4,000 above £300,000. Adjusted income is your total taxable income – so includes all salary, bonus and commissions, dividends, rental income, savings interest plus the add back of any employer pension contributions.

If your payments go above the annual allowance you’ll be subject to a tax charge (the “annual allowance charge”) on the excess so remember to look at all of your pension contributions, not just the ones through your umbrella company, and be sure to discuss with you Pension Adviser.
