Is my military pension/retirement income taxable to Mississippi?

According to the Mississippi Department of Revenue booklet, military retirement is not included onto your Mississippi return. 

This exclusion is not automatically calculated by the program when you create your Mississippi return. You will need to manually exclude this income by going to:

1. State Section
2. Mississippi Return
3. Subtractions From Income
4. Enter the portion of Pension and IRA Income from Federal, State and private retirement systems that are Exempt from MS tax
5. Select "Continue" to save
