Hogan is making the proposal Tuesday. He is speaking to the Maryland Fraternal Order of Police in Solomons, Maryland.
Hogan's campaign estimates the proposal would cost about $10 million annually. He believes the cost would be more than offset by encouraging former police to stay in Maryland when they retire and continue to contribute to the local and state economy.
A measure that would have eliminated the income tax on pensions for law enforcement officials and fire, rescue and emergency services personnel over the age of 50 did not pass in the last legislative session.
In July, Hogan called for eliminating the state income tax on military veterans.
