All of 2023, my husband did not work. From Jan-May (I think) he was receiving insurance disability from his job, while waiting for SS Disability to be approved. He started receiving his disability starting October 2023. He hasn't received any back pay as of yet. Does my husband have to file taxes? Also, since I have W2's, can I claim head of household? Thank you for assisting me in filing my taxes. Leah D.
