If the IRS randomly selected returns to examine, I would expect the poor to be samples more than everyone else because that is the largest category. Likewise if the IRS is sending automated letters to anyone that improperly claimed a credit commonly claimed by the poor, then I would expect that to disproportionately affect the poor.
