There are plenty of construction companies that are still using undocumented laborers.

In 2015 when my grandparent's home was being torn down and rebuilt, our construction company used Peruvian and Portuguese undocumented labor, supervised by citizen foremen. We had to use our own electrical and plumbing to ensure it would pass city inspection (rather than have delays with corrections during intermediary visits) and complete on time.

Doubtful. Why? Because any under the table wages are taxed to the company or owner (if sole proprietor). Why pay your employees' taxes?

You're always paying your employees' taxes. Documented workers with social security numbers need employer-provided SS and Medicare taxes paid for their "over the table" wages. A company pays fewer of its employees' taxes for undocumented labor.

Undocumented labor doesn't pay income taxes. So the money is actually taxed in the company.

The net taxes paid is lower if an employer can avoid paying social security and Medicare taxes. Taxes on corporate income are lower (especially if the corporation can find a way to route that money to capital expenditure).

[Fjolsvith]

20% to 30% of an employee's income is straight up income tax paid out of the employee's income. If the employee is under the table, the employee's income is lumped in the employer's for taxable purposes. Social Security and Medicare taxes are maybe 1-2%. Look on any pay stub.

The employer still keeps more money, even if they're paying more in taxes. The employer may end up paying 20% of their income out in taxes, but they keep the other 80%; they're still out 100% of the money they pay to the employee, and if the under-the-table employee costs less than the over-the-table employee, they keep more money at the end of the day. Who cares if you're paying more tax if you have more cash?

And that's before we factor in that the over-the-table employee also costs SS, Medicare, unemployment insurance, overhead costs to administer all this because they clearly don't only have one employee, the list goes on.
