Democrats also neutered the IRS's ability to collect the penalty — to avoid political blowback — giving the uninsured little incentive to pay.

They probably could make you subject to back-up withholding (on interest, dividends, IRA benefits, etc.) if you don't pay the Obamacare penalty.

Then they'd have some of your money to offset against the penalty.

RE: “IRS Penalty”

It's also not clear if the IRS can report non-payment to credit bureaus.

They can't take legal action, of course, but who wants a tax delinquency notice on their credit report?

It's also not clear if the credit agencies or the IRS can dun you, even though they have no legal remedies.
