In February, the university will be mailing a tax form called the 1095-C, which faculty and staff may need when filing taxes for 2018. The form documents eligibility and/or enrollment in JHU medical plans for 2018. This same information will also be reported to the IRS.
The Affordable Care Act page of the IRS website can provide you with additional information about Form 1095-C.
Contact the university's Benefits Service Center with eligibility or enrollment questions at email@example.com or 410-516-2000.
