What is the deadline to obtain health insurance under the Affordable Care Act, and what happens if I miss it?The deadline to enroll in a qualifying health insurance program under the Affordable Care Act is March 31, 2014, according to the federal website www.healthcare.gov. Under the law, each individual is required to obtain an eligible health insurance plan by that date or pay a penalty, often called the “individual responsibility payment,” when filing 2014 income taxes. This fee is designed to increase every year; in 2014, the fee is either 1 percent of yearly household income or $95 per adult and $47.50 per child in a household, whichever is higher.
