Salary sacrifice is a tax-efficient way to receive valuable workplace benefits while saving on income tax and NI contributions
This is a Q&A brochure titled How Does Salary Sacrifice Work and How do I Get My Employer to Implement a Scheme?
This guide is designed to help employees understand salary sacrifice and how to encourage their employers to set up a scheme.
What is Salary Sacrifice?
Salary sacrifice is an arrangement where an employee agrees to give up part of their pre-tax salary in return for certain benefits provided by their employer.
These benefits can include additional pension contributions, company cars, or cycle-to-work schemes. By reducing taxable income, both the employee and employer save on National Insurance (NI) contributions and income tax.
What Are the Benefits of Salary Sacrifice for Employees?
Salary sacrifice allows employees to:
- Pay less income tax and NI due to the reduced taxable salary.
- Enjoy valuable non-cash benefits, such as increased pension contributions, childcare vouchers, or access to a company car.
- Make long-term savings, especially when contributing to pensions or receiving other work perks tax-free.
What Benefits Can Be Offered Through a Salary Sacrifice Scheme?
Typical benefits that can be offered through salary sacrifice include:
- Pension contributions (the most common and popular)
- Cycle-to-work schemes
- Company cars, including electric vehicles
- Childcare vouchers (for schemes set up before October 2018)
- Health insurance or medical benefits
- Technology purchases (phones, laptops, etc.)
How Does Salary Sacrifice Benefit Employers?
Employers also benefit from salary sacrifice schemes by:
- Reducing their National Insurance contributions, as the employee’s gross salary is lowered.
- Offering competitive benefits packages that can help retain staff and attract new talent.
- Promoting workplace well-being by providing perks such as health insurance or fitness schemes.

How Easy Is It for Employers to Implement a Salary Sacrifice Scheme?
Implementing a salary sacrifice scheme is relatively straightforward, provided the employer has a suitable payroll system in place. Here’s what they need to do:
- Review Benefits: Decide which salary sacrifice benefits to offer.
- Adjust Payroll: Set up payroll to account for reduced salaries and manage the tax and NI calculations.
- Communicate with Employees: Clearly explain the scheme to employees, including how it works and the potential tax advantages.
- Compliance with HMRC: Ensure the scheme complies with HMRC guidelines, especially ensuring employees' post-sacrifice salary doesn’t fall below the National Minimum Wage.
With the right resources, setting up the scheme can be done efficiently.
How Do I Convince My Employer to Implement a Salary Sacrifice Scheme?
Here’s how you can approach your employer to consider implementing a salary sacrifice scheme:
- Present the Benefits: Explain the mutual tax and NI savings for both the company and employees. Show how it can enhance their benefits offering, making the company more competitive.
- Highlight Employee Demand: If multiple employees are interested in the scheme, highlight the collective interest. Employers are more likely to consider it if they see broad demand.
- Provide Examples: Show examples of other businesses in your industry offering salary sacrifice schemes to stay competitive.
- Offer to Help: Suggest that you or a small group of employees assist in gathering information about the process, including benefits and tax savings, to ease any burden on HR or finance departments.
- Use External Resources: Point your employer to HMRC’s resources or professional advisors who can provide specific guidance on setting up a compliant scheme.
How Do I Join a Salary Sacrifice Scheme Once My Employer Implements It?
If your employer sets up a salary sacrifice scheme, joining is simple:
- Choose Your Benefits: Your employer will likely provide a list of available benefits you can choose from.
- Sign an Agreement: You’ll need to sign a written agreement to reduce your salary in exchange for the chosen benefits.
- Payroll Adjustments: Your payroll will automatically reflect the reduced salary, and the non-cash benefits will be provided accordingly.
Your employer should provide guidance on how the process works and the associated benefits.
What Are the Potential Drawbacks of Salary Sacrifice?
While salary sacrifice offers tax savings, it’s important to consider potential drawbacks:
- Impact on Entitlements: Statutory payments such as maternity or paternity leave, redundancy pay, and state pension contributions may be affected as they’re often based on gross salary.
- National Minimum Wage: Employees cannot reduce their salary below the National Minimum Wage, so lower-income employees may not benefit from salary sacrifice.
- Long-term Commitments: Salary sacrifice agreements are typically fixed for a period (often one year), so consider your long-term needs before opting in.
How Can Employers Ensure Salary Sacrifice Compliance with HMRC?
Employers must comply with HMRC rules, including:
- Ensuring the post-sacrifice salary doesn’t fall below the National Minimum Wage.
- Keeping written records of salary sacrifice agreements.
- Monitoring payroll to ensure accurate calculations of tax and NI contributions.
Employers should consult a payroll specialist or HMRC’s guidelines to ensure full compliance.
What If I Change My Mind After Joining a Salary Sacrifice Scheme?
Once you’ve entered into a salary sacrifice agreement, you’re generally locked into it for a set period (usually one year).
However, if your personal circumstances change—such as moving to part-time work, taking maternity leave, or experiencing financial hardship—some employers may allow you to revise or exit the scheme. It’s important to discuss these details with your employer beforehand.
Conclusion:
Salary sacrifice is a tax-efficient way to receive valuable workplace benefits while saving on income tax and NI contributions.
By presenting the mutual advantages of salary sacrifice to your employer—such as tax savings and a more competitive benefits package—you can encourage them to implement a scheme that benefits both the company and its employees.
Once the scheme is in place, joining is easy and offers long-term benefits.
Whilst this brochure provides a concise overview of how salary sacrifice works in the UK for employees and employers and the steps needed to implement it efficiently, it is not a legal guide and employers should ensure they are up to date with all relevant laws and guidelines.
It does however serve as an informative resource for employees and businesses considering adding this benefit to their employee offerings.
