Hopefully you knew, because of this blog or some other source, that the mandate to have health insurance as an individual continued through 2018 (so it will still apply to the taxes season coming up).
In 2019 the federal mandate will be finally gone, although some states may have their own (Massachusetts and New Jersey already have them, and Vermont will have one in 2020).
However, because of that repeal, insurance costs are projected to rise quite a lot. The non-partisan Congressional Budget Office (CBO) has projected that “[A]verage premiums in the non-group market would increase by about 10 percent.” Additionally, the CBO projects that about about 4 million fewer people will have health insurance.
