If a question asks you about “someone else who isn’t applying for health coverage,” check the box if there’s anyone in your household you haven’t told us about yet. This person may be submitting his or her own Marketplace application or might already have health coverage. We’ll need to know about all the people in your household to tell you how much help people who do want health coverage can get. We won’t ask about citizenship or immigration for household members who don’t want health coverage. It’s also optional for you to tell us their Social Security numbers (SSNs), although entering their SSNs could speed up the process for family members who do want help paying for coverage.
