For Child Tax Credits yes they let them use ITINs, they were not supposed to let them do that for EIC which is the bigger credit/refund. Breitbart did a story a few years back that illegals were using fake and other people’s SSNs to get the EIC...and when notified by Social Security the numbers did not match the IRS has been ignoring that and allowing illegals to continue to get that as well.
It has been total insanity and will not be easy to fix but it has to be fixed, tons of money being paid out to illegals and obviously we cannot afford it and even if we could it is not right.
The truth is for many years our government has been allowing illegals to game the system and collect a lot of money that they should not be able to get; not just from the IRS but government wide, agency after agency. Not only allowing illegals to game the system, but figuring out ways to make it easier for them to do so.
We must face the fact that our own government, along with Democrats, RINOs have decided illegals and refugees are far more important than citizens. President Trump will face an uphill battle all the way fighting this system wide corruption and theft of tax dollars. I hope he can manage to turn the tide but it will not be easy and it is one of the reasons the establishment is out to get him.
Stopping him from restoring the rule of law and removing the illegal aliens is THE reason they are out to get him.
