How to Get the Premium Tax Credit From the Affordable Care Act

You may have to pay money back if you paid into the Affordable Care Act.

Smith says those who got the tax credit may have wrongly estimated their 2014 earnings -- meaning they'll have to reconcile the cost, either paying more or receiving a tax credit.

"Some people may find they got an advanced payment that was not as much as they actually qualified for, and others maybe a little more,” said Smith. “Some are going to be a little up. Some are going to be a little down."

Anyone who purchased government-backed health care and didn't claim the Premium Tax Credit in advance are now eligible to claim it in full.
