Richie’s parents have been generous with Richie over the years. Richie is a 21 years old and works at a local Hawaiin Shave Ice shack while attending college. Richie earned $2,000 at his job and received $4,000 in investment income. When not at school, Richie lived at home. Richie’s work income went to pay for his college student life-style (some road trips to away games and eating out with friends). Richie’s parents pay for his housing. What is Richie’s filing status and tax liability for 2018?
