You may encounter a case with a new or existing employee where Social Security Contributions (SSC) are not being deducted. There can be several reasons why SSC is not being deducted. 

What would you need to check?

1. Confirm that the employee has the Deduct N.I. Payments from Salary setting enabled.
   Note: Such a setting is found in the employee's profile, under the Payrun Adjustments tab
   
   
2. Confirm that the employee does not have any No NI Mondays selected for the employee in a pay run.
   Note: For more information on how NI can be adjusted in a pay run click here.
   
   
3. Low income. The employee's Basic Weekly Wage is not enough to be liable to pay SSC.
   
   
4. Employee's age is 65 years or more.
