You’ll get a yearly tax bill from the IRS for $2500 or some such thing. You can’t be off the rolls without paying for it. That’s why it went to SCOTUS.
Not that much right away. My understanding is that the penalty is phased in over a few years. A couple hundred dollars the first year, little more the next....Eventually it will be $2,500.
But notice, even when it gets to $2,500, it is still *significantly* cheaper than buying a health-insurance policy. This is by design:
Nobody will purchase insurance until they are sick (they'll pay the cheaper penalty). Then, when they get sick, they will purchase a policy, since no company can deny them for pre-existing.
Within a few years, all insurance companies will go broke, with no healthy people paying in. Or the companies will see the writing on the wall, and just get out. Either way, all that will be left for us is "public" health insurance.
