Those without health insurance will have to cough up $95 per person or 1 percent of their income, whichever is greater. That penalty eventually jumps to $695 or 2.5 percent.

The White House expanded the list of exemptions allowing the uninsured to bypass the penalty for legitimate reasons, including religious restrictions, falling on rocky times or a death in the family. Another big out created after the controversy over canceled health plans was the so-called affordability exemption that allows people to opt out if premiums are still not affordable.

The Congressional Budget Office expects 23 million of the 30 million Americans who remain uninsured in 2016 to qualify for exemptions. It’s part of the reason the CBO in June downgraded from 6 million to 4 million the number of people it estimates will pay the penalty.
