The individual shared responsibility payment
If you can afford health insurance but choose not to buy it, you must pay a fee known as the individual shared responsibility payment.
The fee in 2014 is 1% of your yearly income or $95 per person for the year, whichever is higher. The fee increases every year. In 2016 it is 2.5% of income or $695 per person, whichever is higher.
In 2014 the payment for uninsured children is $47.50 per child. The most a family would have to pay in 2014 is $285.
You make the payment when you file your 2014 taxes, which are due in April 2015.
