The IRS doesn't really care about your immigration status, they care about you reporting any income and paying your fair share of taxes.
As of right now, the IRS doesn't coordinate with ICE or Homeland Security. If they did and got you deported, how would they get any your money in the present fiscal year and in future years? Duh ... Common sense. It's all about the money.
