Your payroll provider might’ve told you:
“Yes, we can add your ITIN workers to payroll.”
But here’s what they’re not telling you…
Most payroll companies say they support ITIN workers—but they’re doing it the wrong way.
Some file payroll tax returns with an incorrect ID number like 000-00-0000
Others tell you to change the ITIN number to a different leading number (other than 9)
This isn’t just shady—it adds financial risk to you and your business.
For over 20 years, Baron Payroll has helped business owners like you add ITIN workers to payroll the correct way.
We file the actual ITINs on every payroll tax return—941s, W-2s, most state reports—with zero shortcuts.
We've rarely had an issue with an ITIN filing, except recently for a few states.
99% of the time... No mismatches. No fake IDs. No workarounds.
We wrote this to protect business owners like you who are being misled by other payroll companies.

If you’re a business owner who employs workers with ITINs (Individual Taxpayer Identification Numbers), you’ve probably heard this line before:
“Yes, we can add ITIN workers to payroll.”
Sounds good, right?
But here’s the problem: many payroll companies are saying it—but doing it wrong.
And that can put your employees and your business at serious risk.
Some payroll companies try to “trick” the system.
Here’s what we’ve seen:
Adding ITIN workers to payroll using all 0s or someone else's Social Security number in place of the ITIN number
Changing the Social Security Number on tax returns to something other than the real ITIN
Submitting 941s and W-2s with fake Social Security Numbers
Keeping employers in the dark—because you only see the last 4 digits on reports
And that last point is the kicker: most employers have no idea it’s happening.
Until it’s too late.
This is what can happen when a payroll company submits tax filings under the wrong Social Security Number:
In one case we saw, a payroll provider incorrectly filed wages earned by an ITIN worker under someone else’s Social Security number—an individual who had absolutely no connection to the business.
The result?
That innocent person suddenly appeared to be earning far more income than they actually were. And because of that, they almost lost access to their federally subsidized housing.
That person had no idea their Social Security number was used. They weren’t involved in the business at all—and yet their life was turned upside down.
This is what happens when payroll companies change or invent Social Security numbers. It not only robs the ITIN worker of credit for their earnings—it can devastate innocent people who get caught in the crossfire.
You might think:
“I see the last 4 digits of the ITIN on payroll reports—it looks fine.”
But that’s exactly the problem.
You don’t see the full number that was submitted to the IRS and your state.
If your payroll company changes the ITIN number or invents Social Security numbers:
Your employee’s wages may not be recorded correctly with the IRS
They may not qualify for loans, tax refunds, or benefits later in life
You could be held liable for filing false payroll returns—even if it was unintentional
And now, you might unknowingly be affecting innocent third parties
The IRS and Department of Labor won’t blame your provider.
They’ll come after you.
If you’re currently paying—or planning to pay—workers with ITINs, ask your payroll company:
1. Are the full ITINs being used on all payroll filings, including 941s and state returns?
If they hesitate or say “we use a generic number,” that’s a red flag.
2. Do the W-2s and 941s have your workers' exact ITIN number?
They must. If not, it’s a huge compliance risk.
