There are numerous new tax provisions coming as a result of the Affordable Care Act. Some have already been enacted, some will be coming in 2013 and others, like the individual mandate penalty, are coming in 2014 and later.

The SCOTUS’ decision on the law may impact only parts of the law or may impact the entire law (or leave it intact).
