If you served 120 or more consecutive days on active duty as a member of the armed services of the United States, the pay you and/or your spouse receive from the armed services while serving outside of Louisiana is exempt from Louisiana income tax.
Example: On January 15, 2018, you went on active duty and continuously remained on active duty at least through May 14, 2018 (120 days). Up to $30,000 of compensation paid to you and/or your spouse by your branch of the armed services may be exempt from Louisiana income tax. The exempt portion is that amount of compensation earned outside of Louisiana during and after 120 plus consecutive days of active duty. In the above example, if you served 40 days in Louisiana and the remainder of duty outside of Louisiana, income from the 41st day forward is exempt once you have served 120 plus consecutive days of active duty.
Only $30,000 total of qualified military compensation paid to you and/or your spouse is excludable.
You should keep a copy of your active duty orders, including endorsements, in your records as proof of eligibility.
