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 (8.16 percent in 2017), 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).
