Here in MA we've had health insurance non-coverage penalties for years. They are a ROYAL pita; charts up the wazoo by county, by income, by family size, all needing to be cross-correlated. Software doesn't do all those calculations very well (ATX didn't do them at ALL - I had to look up every piece separately on the MassDOR book that I downloaded; Drake at least is able to pull the county and income info over and you add in the family size since that can be [often is] different from the exemption number), so there is lots of do-it-by-hand nonsense.
Folks most likely to be hit are low income or those who had jobs and lost them and decided not to pay for COBRA coverage. Plus in MA we also have a requirement for "minimum creditable coverage" so there are still folks who don't meet *that* criterion and get penalized. Some do it every year, as the insurance they have is sufficient for their needs and the penalty is less than the step-up in coverage.
My recommendation is to buy your Motrin in the convenient 55 gallon drum package for next tax season. Perhaps install a dispenser like the ones for gumballs/Skittles/M&Ms you still see in stores.
