Under the law, most Americans will be required to have health insurance starting next year. Low- and middle-income people can get tax credits to help them pay premiums, unless they have access to affordable coverage from an employer.
The law specifies that employer-sponsored insurance is not affordable if a worker’s share of the premium is more than 9.5 percent of the worker’s household income. The I.R.S. said this calculation should be based solely on the cost of individual coverage, what the worker would pay for “self-only coverage.”
