Problem
Can you please answer this problem:
John and Joan had been married for 20 years before John died in October 2013. Joan and her son Marley, age 21, continued to live at home in years 2013 - 2016. Marley worked part-time (earning $5,000 in each of the four years). He also attended college on a part-time basis. Joan provided more than 50% of Marley's support in each year. What is Joan's filing status for 2013, 2014, 2015, and 2016? Would Joan's filing status change if Marley attended school full-time rather than part-time? If so, how?
