Hello. My jurisdictional court officially assigned me as legal guardian of my disabled adult brother in December 2021. His 2021 living expenses were paid for by a combination of his only income (Supplemental Security Income from Social Security, totaling approx. $11,500 for 2021) plus some additional unknown amount from my our who he resided with for all of 2021. Would my brother be able to be claimed as a dependent for 2021 tax filing purposes? If yes, would the claimant be my mother, or would it need to be me (Legal Guardian)? Thank you.
