MI HB4201

Expands the state income tax exemption for retirement and pension benefits to include corrections officers employed by the state (Michigan Department of Corrections), in addition to those employed by county sheriffs in county jails, work camps, or other county-operated detention facilities

Allows qualifying corrections officers to fully deduct their retirement and pension benefits from taxable income without the age-based limitations that apply to other retirees born after 1945

Removes outdated effective date language throughout the tax code (such as "Beginning January 1, 2012" or "For tax years that begin after December 31, 2018") to simplify the statute

Updates statutory citations for the federal Social Security Act from the historical reference (chapter 531, 49 Stat 620) to the current U.S. Code citation (42 USC 301 to 1397mm)

Applies retroactively to tax years beginning on and after January 1, 2023
