Undocumented immigrants pay substantial amounts toward the funding of public infrastructure, institutions, and services. Specifically, we find that in 2022, undocumented immigrants paid $96.7 billion in taxes at the federal, state, and local levels. More than a third of that amount, $33.9 billion, went toward funding social insurance programs that these individuals are barred from accessing because of their immigration status.

I practiced in the tax field for too many years. I can verify ITEP as a legitimate source.
Unfortunately it’s still a common belief that undocumented immigrants either work under the table or work under a stolen SSN.
A stolen SSN would still be adding surplus money to social security they cant access.
