What Does an ITIN Mean for Immigrants?

An ITIN is a nine-digit tax processing number issued by the IRS since 1996 under IRC 6109. The IRS created the ITIN program to ensure all individuals earning income in the US can meet their tax obligations regardless of immigration status.

How Does IRC 6103 Protect ITIN Holders from Information Sharing?

IRC 6103 makes it a federal crime for the IRS to disclose taxpayer information to other government agencies without specific legal authorization. This protection covers all ITIN holders.

Specific Protections Under IRC 6103

IRS cannot share tax return data with ICE (Immigration and Customs Enforcement)
IRS cannot share data with CBP (Customs and Border Protection)
IRS cannot share data with USCIS except when you authorize verification
Violations carry criminal penalties: fines up to $5,000 and up to 5 years imprisonment
