Let's think about this in simple terms of revenue and expense.
The revenue loss is the loss of tax revenue and labor productivity of deported people
The expense is the resources expended, direct and indirect, to round up, detain and physically deport thousands (millions?)
Do undocumented people pay taxes? Most people instinctively assume no. According to two non-partisan studies I have read, this is not the case.
Here are some numbers:A significant percentage of undocumented immigrants in the United States do pay taxes, although precise estimates vary depending on the methodology used. Here's an overview of the most reliable statistics:
1. Tax Participation of Undocumented Immigrants
Federal, State, and Local Taxes: The Institute on Taxation and Economic Policy (ITEP) reports that approximately 50-75% of undocumented immigrants contribute to federal, state, and local taxes, including:
Payroll taxes: Many undocumented immigrants pay Social Security and Medicare taxes through employer withholding, even though they cannot access benefits.
State and local taxes: These include property taxes (paid directly or indirectly through rent) and sales taxes on goods and services.
2. Use of ITINs (Individual Taxpayer Identification Numbers)
The IRS allows undocumented immigrants to file income tax returns using an Individual Taxpayer Identification Number (ITIN).
In 2020, over 2.5 million ITIN filers contributed an estimated $5.9 billion in federal income taxes and about $1.6 billion in payroll taxes.
ITIN filers typically include undocumented immigrants who voluntarily comply with tax laws to maintain a record of tax contributions, which can be helpful for potential legalization efforts.
Those in formal employment pay through employer withholding.
Those in informal employment contribute primarily through sales and consumption taxes and, in some cases, income tax filings with ITINs.
Tax Participation Rate 50-75% of undocumented immigrants pay federal, state, and local taxes.
Federal, State, and Local Taxes Includes payroll taxes (Social Security & Medicare), income taxes, sales, and property taxes.
ITIN Filers Over 2.5 million ITIN filers in 2020 contributed $5.9B (federal income) & $1.6B (payroll taxes).
Annual Tax Contributions ~$11.7 billion in state and local taxes by undocumented immigrants annually.
Social Security Taxes ~$12 billion annually contributed to Social Security by undocumented workers.
Contribution Channels Taxes paid via employer withholding, ITIN filings, sales taxes, and property (direct/indirect)
It becomes more interesting when we consider that those among the undocumented that pay in are not eligible to take anything out in the form of benefits, so it is a net revenue. For the rest of us, the net number becomes what we have paid in minus what we have taken and will eventually take out.
Why do undocumented people bother to pay in at all? According to Cato Institute's paper, it is because they are trying to improve their case for eventual legal immigration. Most immigration attorneys will advise their clients to pay taxes to improve their odds of obtaining legal status.
What about the cost of deportation? I've tried to get to the bottom of it and it's not easy. Between arrest, legal processing, detention and actual deportation, it is looking like a big number, like in the range of $30,000 per deportee. So figure $30B per 1MM deportees. Estimates are that there are 11MM undocumented people in the US. But nobody thinks they will successfully deport them all.
So the net impact of both sides of the equation could be quite large $50B+?
All this in mind, I ask again, is this program economically rational?
When asked this question directly, Tom Homan's answer has been "that's the price of security". Is it worth it?
