<prompt> Human: I have a girlfriend with a debilitating mental illness that makes her unable to function healthily enough to hold a job for herself without getting into specifics, she breaks down in a panic attack if she leaves the house without me. Weve lived together for 2 years now, but I didnt claim her on last years taxes. Does she count as a dependent? I checked the FAQ and it seems like she checks out based on the flowchart: Not married US Citizen Lived in household for more than a year Has income less than 3,950 didnt make any income I provide all her financial support She isnt claimed on anyones taxesOn another note, I do plan on getting a disability lawyer to help her out with supplemental income sometime soon, and shes currently in therapy and visiting a psychiatrist that I pay for but thats a different story for another time. I just felt like putting that there in case any of you were worried about her.  <response>: She probably has health insurance if she has mental illness, but just wanted to point out that if she does not have health insurance and you do, if you claim her as a dependent you will have to pay the ACA individual mandate penalty 4 of income next year I think because someone in your household did not have health insurance.
