They just showed on Fox News what the tax will be if you don't have the coverage. -> In 2014, if you don't have the coverage, you will be faces with a 1.5% tax on your income. It will grow each year after that till 2016 when a total of 2.5% of your income will be going towards the tax.
So what it looks like to me is that if you don't have the coverage they are going to tax you, but if you do have it, they won't tax you. Either way you look at it, depending on your income, it will be cheaper to pay the tax than it will be to get the coverage.
