People who do not have health insurance will have to pay a tax until they get health insurance. This part of the act is called the individual mandate. The Supreme Court of the United States decided that the government has a right to give this tax under the United States Constitution. The amount that people will have to pay if they do not have health insurance will increase every year until 2016. Some people without health insurance will not have to pay this tax, such as poor people who cannot get insurance for free.
