Difference Between SSN and ITIN
Understanding the distinction between Social Security Number and Individual Taxpayer Identification Number is essential for proper tax compliance.
In the United States, both SSN (Social Security Number) and ITIN (Individual Taxpayer Identification Number) are used for tax reporting, but they serve different purposes and are issued to different groups of people.
SSN
SSN is issued by the Social Security Administration (SSA) to U.S. citizens, green card holders, and authorized workers. It’s a multipurpose identification number used for employment, tax filing, credit applications, and government benefits.
- Issued by Social Security Administration (SSA)
- For U.S. citizens and authorized residents
- Used for employment and work authorization
- Required for Social Security benefits
- Used for credit applications and banking
ITIN
ITIN is issued by the Internal Revenue Service (IRS) to nonresidents and foreign nationals who are not eligible for an SSN but still need to file U.S. taxes or report U.S. source income.
- Issued by Internal Revenue Service (IRS)
- For nonresidents without work authorization
- Used exclusively for tax reporting purposes
- Does not provide work authorization
- No Social Security benefits eligibility
