Most immigrants who are residents lawfully present in the U.S., including “green card holders,” must have health insurance coverage or they will pay a tax penalty unless they qualify for an exemption. Check with your marketplace for more information about how the requirement applies to you, or if you want to apply for an exemption.
Immigrants who are not lawfully present in the U.S. will not pay a tax penalty if they do not have health insurance. (26 U.S.C. § 5000A).
