On the New Jersey personal tax form NJ-HCC, I have clients who had coverage for the first six months of the year, then couldn't afford it anymore, as it was un-affordable, costing more than 8.05% of their income.  I tried entering "A-1" on the exemption code for the coverage being considered un-affordable and nothing happened, the penalty for not having health insurance won't go away.  I tried entering other codes, just to see what would happen, i.e. religious exemption code but nothing changed.  Any idea how to make this penalty by entering exemption?

Thanks in advance.
