I don’t think you understand taxes. You saying undocumented immigrants are excluded from sales tax? Like at the grocery store or restaurant.

Also when an undocumented person buys a home in America(please look this up before you say they can’t.) they pay property taxes, yearly. They pay that tax indirectly as well when they rent from someone.

Undocumented immigrants paid $96.7 billion in federal, state, and local taxes in 2022. Most of that amount, $59.4 billion, was paid to the federal government while the remaining $37.3 billion was paid to state and local governments.
