I mean, time was an undocumented immigrant could file their taxes with the irs and the irs would fight any other government agency that tried to find out which people who filed their taxes were undocumented, because giving away that information destroyed any incentive any undocumented immigrant has to file tax returns or pay taxes. Not filing their returns, that’s just a fine. Giving their informaron to immigration? That’s a hell of a lot worse than not filing. Someone logic this out for me, should the irs cooperate with criminal investigations or no? It seems to be a violation of someone’s right against self incrimination, but of course I’m sure there’s scatus case law saying otherwise.
