Question: how much money do i need to earn before i pay tax?
Answer: You must file a 2018 return if: You had more than $1,050 of unearned income (typically from investments). You had more than $12,000 of earned income (typically from a job or self-employment activity). Your gross income was more than the larger of $1,050 or earned income up to $11,650 plus $350.
