Military Servicemembers

In general, a military servicemember is any member of the Army, Navy, Air Force, Marine Corps, Coast Guard, or Space Force. Several special rules apply in determining the Colorado income tax liability of an active duty or retired military servicemember. Whether and how a servicemember's income is taxed depends largely on the service-member's state of legal residence. Additionally, military retirement benefits may be fully or partially exempted from Colorado taxation.
