Auto-enrolment and salary sacrifice

A workplace pension is a way of saving for retirement that’s arranged by employers. They generally work by putting a percentage of a staff member’s pay directly into a pension scheme.

Employers may also need to pay contributions to a pension scheme where the staff member is eligible for auto-enrolment.

All employers are required by law to provide a workplace pension for certain employees. This requirement is known as automatic enrolment (or the auto-enrolment duty) and it applies to all staff who:

• classed as workers ‘worker’
• are aged between 22 and the State Pension age
• earn at least £10,000 per year
• work in the UK

From April 2019, employers must pay at least 3% of an employee’s qualifying earnings (ie their salary before tax) into this workplace pension. They must also deduct contributions of at least 5% from each eligible employee. If these levels of pension contribution are already made through an existing workplace pension scheme, there is no need to take any action, as the requirements of auto-enrolment will be fulfilled.

For more information on when employers don't typically automatically need to enrol staff in a workplace pension, read the government's guidance.

Staff members who do not wish to take advantage of auto-enrolment can choose to opt-out. They have one calendar month, known as the ‘opt-out period’, to formally leave the scheme and get a full refund of any contributions. In order to opt-out, staff must obtain an opt-out notice from the pension scheme, complete this and return it to their employer.

Some key points to bear in mind regarding opting out include:

• a decision to opt-out must be taken freely and willingly, without any pressure being put on the employee
• the opt-out period starts from the later of the day the active membership is created or the date an employee receives the letter containing auto-enrolment information
• employers are required to issue a full refund of any contributions the staff member has made into a pension scheme within a month of receiving a valid notice to opt-out

An employer can make a contractual agreement with an employee to alter the terms of the original employment contract, in order to reduce cash salary payment in exchange for some form of non-cash benefits, such as enhanced pension contributions or childcare vouchers. This type of contractual change, known as salary sacrifice (or salary exchange), can have advantages for both employer and employee, in the form of reduced national insurance contributions.

It is vital that any type of salary sacrifice arrangement does not result in cash salary payments falling below the level of the National Minimum Wage.

A salary sacrifice arrangement, where cash payments are reduced in exchange for pension contributions, can essentially fulfil the auto-enrolment obligation if the employer and employee's required levels of contributions are made.

However, it is important that employers do not oblige or induce their employees to opt out of auto-enrolment (eg by implying that salary sacrifice is a pre-condition of auto-enrolment).

A few issues which should be kept in mind when considering a salary sacrifice arrangement include:

• Any changes to earnings-related payments (eg pensions and overtime rates) which result from a reduction in cash salary are made clear to the employee.
• Earnings related benefits such as maternity allowance may be affected by a reduction in cash salary.
• Salary sacrifice can affect an employee’s entitlement to contribution-based benefits such as the state pension and the Employment and Support Allowance.
• Entitlement to statutory pay (eg sick pay, maternity and paternity pay) can potentially be lost if a salary sacrifice arrangement reduces an employee’s average weekly earnings below the lower earnings limit.
• Employers are responsible for ensuring that they pay and deduct the right amount of tax and National Insurance Contributions (NICs) for the cash and benefits they provide.
• Employers are also required to report any non-cash benefits to HMRC at the end of the tax year. Some non-cash benefits may be exempt from tax and disregarded before calculating NICs, however, any conditions that apply to the exemptions must be satisfied.

It is possible to postpone pension enrolment for the first 3 months of a worker’s employment. To do so, the employer must write to the employee stating that they intend to postpone pension enrolment. This letter must be sent to the employee within the first 6 weeks of their employment. Where an employee is on a fixed-term contract lasting less than 3 months, it may be possible to avoid pension enrolment altogether using this method. 

Upon receiving the letter, the employee can either accept the postponement, or they are entitled to request immediate enrolment into the pension scheme. If an employee does request to be enrolled, then the employer must do so as soon as possible. 

At the end of the postponement period, the employer should assess whether their employee meets the age and earnings criteria to be put into a pension scheme, as set out above. If they do, the employee must be immediately put into a pension scheme, and pension contributions must be paid. It is not possible to postpone the pension contributions of a new employee beyond the initial 3 month period. For more information on pension postponement, please refer to the government guidelines.
