A threat of a massive tax penalty will do that.

The number of Wisconsinites enrolling or automatically re-enrolling for health insurance via the Affordable Care Act online exchange increased 16.1 percent for the 2016 plan year as federal officials declared the latest enrollment period a success for the program.

The threat of a higher tax penalty in 2016 was a major driver of the increase in the number of Wisconsinites enrolling, according to health benefits brokers and organizations that enroll people in metro Milwaukee. The penalty on federal income taxes for individuals who don’t get insurance is increasing to $695 per adult or 2.5 percent of a household’s income in 2016 from $325 or 2 percent in 2015.

This stat is interesting, though.

In 2015, the final number for people who paid premiums in Wisconsin was 183,155, or 11 percent less than the enrollment figure.
