Employers who supply differential pay, must provide it to an employee if he or she earns less in the military than they would earn in his or her position. Differential pay is the difference between the employee’s military earnings and employment earnings.

The following table shows an example of how to calculate differential pay:

 

WRS Employer Earnings Subtract Military Service Earnings Differential Pay Total
$40,000 - $30,000 = $10,000

 

Retirement contributions come out of differential pay according to Federal law. The employer submits WRS employee-required contributions to ETF based on annual earnings of only the differential pay amount.

Using the differential pay example above, the following table shows how to calculate employee-required contributions from the employee’s differential pay:

 

Differential Pay Multiplied by the 2019 Employee-Required Contribution Rate (6.55%) Employee-Required Contributions
$10,000 x .0655 = $655
