Yes. But my point is that the IRS has a process for declaring and paying tax on income that you got illegally, whether it’s from being a mobster or working without the right visa.
Capone didn’t follow that process, so got done for tax evasion.
These illegal immigrants are paying their taxes, and therefore a) they aren’t exposed to prosecution for tax evasion, and b) the IRS won’t rat them out to ICE.
These illegal immigrants are paying their taxes
The vast majority of them are earning under the standard deduction and don’t actually owe anything. Individuals don’t owe taxes on income under $29.2k and the cheap labor migrants provide mean they often earn far less. Since they aren’t eligible for any refundable credits, this means there’s no incentive to file.
Where they pay their taxes is typically on the consumer end - sales, real estate, gas/utilities taxes, etc.
