Distributions Used To Pay Insurance Premiums for Public Safety Officers
If you are an eligible retired public safety officer (law enforcement officer, firefighter, chaplain, or member of a rescue squad or ambulance crew who is retired because of disability or because you reached normal retirement age), you can elect to exclude from income distributions made from your eligible retirement plan that are used to pay the premiums for coverage by an accident or health plan or a long-term care insurance contract.
