"February 5, 2021 is the deadline for Michigan public school districts to submit a Form 2848 to the State of Michigan Office of Retirement Services to participate in and be covered by the proposed IRS closing agreement related to 3% retiree healthcare contributions. Michigan public school employees who did not opt out of retiree health coverage under the Michigan Public School Employees Retirement System Act are required to make 3% contributions to ORS for retiree health coverage.... For a limited time, the IRS is allowing Michigan public school districts to participate in a closing agreement that favorably resolves the tax treatment of these contributions. The IRS indicated that the closing agreement will provide that the retiree healthcare contributions are exempt from federal income and FICA taxes."
