Massachusetts is the only state that requires its residents to obtain health insurance, although it exempts some people who cannot afford it. Those who do not comply face a fee. * Penalties and income levels are for individuals. Penalties for married couples equal the sum of individual penalties for each spouse. **Based on an early estimate that about 1 percent of the state's population would be exempted on affordability grounds.
