Janice Traylor is single. She has an 18-year-old son named Marty. Marty is Janice’s only child. Marty has lived with Janice his entire life. However, Marty recently joined the Marines and was sent on a special assignment to Australia. During the current year, Marty spent nine months in Australia. Marty was extremely homesick while in Australia, since he had never lived away from home. However, Marty knew this assignment was only temporary, and he couldn’t wait to come home and find his room just the way he left it. Janice has always filed as head of household, and Marty has always been considered a qualifying child (and he continues to meet all the tests with the possible exception of the residence test due to his stay in Australia). However, this year Janice is unsure whether she qualifies as head of household due to Marty’s nine-month absence during the year. Janice has come to you for advice on whether she qualifies for head of household filing status. How would you advise her?
