In 2010, the Affordable Care Act (ACA) was signed into law by then President Barack Obama. Also called, "Obamacare," the ACA virtually transformed the way Americans access health insurance. Now, with the new presidential administration, health care is poised to go through another major shift. Until the new health care plan goes into effect, Americans are still subject to the ACA, which requires everyone who can afford it, who does not receive health insurance as an employment benefit to purchase it or pay a penalty. The fee that Americans will be charged when they pay their taxes is either a percentage of annual household income, or a specified amount for each person in the household who is not insured. You can find out what that penalty might be for you or if you qualify for an exemption at Healthcare.gov.
