Why Employees Love It Too
Offering a salary sacrifice pension is one of the easiest ways for employees to get more from their pay packet.
- Increased take home pay. Employees will see an increase in their take-home pay due to the tax savings from lower National Insurance contributions. 
- Greater pension contributions. Employees can choose to add their additional take-home pay to their pension pot. Employers may choose to add their National Insurance savings to their employees’ pensions. 
There’s no extra effort or extra cost – it’s simply a smarter way to save.
Any Downsides?
Salary sacrifice can have an impact on anything that is linked to an employee’s salary. Here are a few things that may affect your decision to switch to a salary sacrifice scheme.
How to Set Up a Salary Sacrifice Pension
Setting up a salary sacrifice pension can be straightforward if your existing provider already provides the option:
- First, employers should contact their payroll or pension provider. Employers should make sure they can facilitate salary sacrifice within their workplace pension scheme. 
- Employers will need employees’ permission before entering them into a salary sacrifice scheme. Employees will need to agree to the change in their contract or through an agreement letter. 
- Manage opt-outs for employees who don’t agree to salary sacrifice. Employers will need to pay these employees’ pension contributions as previously set up. 
If the company’s existing pension scheme does not offer pensions with salary sacrifice, there are a few options.
- Speak to a pension specialist such as a Financial Adviser or an accountancy firm. This is a common route for employers to get straight-talking advice from an expert. 
- Contact another pension provider. Many workplace pension providers offer salary sacrifice consultations as part of their service. There's often a fee for this service, however Penfold’s workplace pension includes free salary sacrifice consultation and implementation.
