More than 4,700 Marylanders signed up for health insurance during a special six-week enrollment period that helped them to avoid a federal tax penalty in 2015. Many of these were people who were surprised to find they had been charged a penalty in 2014 for not signing up for insurance, according to officials who run the online marketplace where people enroll. By the time they found out about the penalty open enrollment had closed. The special enrollment allowed them extra time to get insurance and not face a penalty in 2015. (McDaniels, 5/4)
