My family wasn’t eligible for subsidies in the marketplace because I was eligible for self-only coverage at work that is considered affordable and we couldn’t afford to buy marketplace coverage on our own. Will I have to pay a penalty?

Individuals with no coverage | Individual Responsibility Requirement (Individual Mandate)

You may qualify for an exemption from the individual mandate penalty. If the amount you would have to pay to cover your spouse and kids via your employer plan exceeds 8.05 percent of your family income in 2018, you should qualify for an exemption and won’t be penalized for not having health coverage. You can claim this exemption at tax filing time. (26 U.S.C. § 5000A (e); 81 Fed. Reg. 94058, Dec. 22, 2016).
