What is an ITIN? A Comprehensive Guide for Employers

What is an ITIN?

If you've landed on this article, you're probably wondering, "What is an ITIN?", and you're not alone. 

As a payroll company that adds ITIN workers to payroll, we get this question all the time.  

As an employer, understanding various tax identification numbers, such as ITIN and SSN, is crucial for managing a diverse workforce. So, we created this guide to help you understand. 

Let's dive into what ITIN means, how it differs from SSN, and how Baron Payroll can help.

What is an ITIN vs SSN?

ITIN (Individual Taxpayer Identification Number) and SSN (Social Security Number) are both tax identification numbers, but they serve different purposes.

ITIN

  • Purpose: ITINs are tax processing numbers issued by the IRS for individuals who are not eligible for an SSN and need a U.S. taxpayer identification number to be included on your payroll. 
  • Eligibility: They are for individuals who cannot obtain a SSN but must comply with U.S. tax laws.
  • Usage: Primarily for tax processing and filing purposes.

SSN

  • Purpose: SSNs are issued to U.S. citizens and permanent residents. 
  • Eligibility: Issued by the Social Security Administration for individuals eligible for Social Security and other benefits.
  • Usage: Used for a wide range of purposes, including employment, tax reporting, and accessing government services.

Understanding this distinction is vital for employers, especially when employing individuals who are ineligible for SSNs.

How Do I Find My Taxpayer Identification Number?

For employees who need an ITIN:

  • Completing Form W-7: This is the IRS application for an ITIN.
  • Providing a Federal Tax Return: A U.S. federal tax return must accompany the application unless exempt.
  • Renewal Requirements: ITINs must be renewed if not used on a tax return for specific years.

As an employer, guiding your employees through this process or seeking professional assistance is important for compliance.

Is an ITIN Number the Same as an EIN Number?

No, an ITIN is different from an Employer Identification Number (EIN).

  • ITIN: For individuals who need a U.S. taxpayer identification number but can't get an SSN.
  • EIN: A unique number assigned to businesses for tax purposes by the IRS, used to identify a business entity.

Understanding these differences is crucial for proper tax management and compliance.
