From the above scenario, it can be seen that implementing a salary sacrifice pension plan option results in the same overall pension contributions on behalf of the employee. However, by sacrificing a proportion of salary which is transferred into employer pension contributions, an employee pays less tax and national insurance and receives more net pay. In this scenario, net pay is increased by GBP138.00. For the employer, salary sacrifice for the pension plan results in a GBP160.00 reduction in employer NICs.
If you have implemented salary sacrifice for a pension plan which also has National Insurance Cost Neutralityapplied, you must determine whether any employer NICs savings produced as a result of the salary sacrifice are paid back to the employee. This process is referred to as pension payback.
