I'm trying to figure out if my son needs to file a Colorado state tax return. He lived in Colorado from January 1-14, 2020, no job and no income during these 2 weeks. He held his Colorado driver's license until July 2020 for a number of reasons. He moved to Tennessee for a job and signed a 12 month lease for an apartment there on January 14, 2020. Before he could establish residency in TN, his apartment building was hit by a tornado and deemed uninhabitable. He was in temporary housing for a month and then signed a 13 month lease for a new apartment location. By the time he had all of his paperwork to establish residency in the new TN apartment, the DMV was closed due to Covid. As a new resident he was required to apply in person which he could not do until July. So I'm not sure if Colorado will require him to file a return. Any insight is appreciated. Thanks.
