Understanding Individual Taxpayer Identification Numbers for Immigrants

William J. Quirk, Esq., LLC  May 14, 2024

Acronym ITIN as Individual Taxpayer Identification NumberTax matters can be baffling for anyone. And for immigrants navigating the U.S. tax system, they may be presented with unique hurdles.  

One particularly high hurdle is the requirement for an Individual Taxpayer Identification Number (ITIN)–an essential piece of identification for immigrants filing taxes in the United States.  

This article is meant to be a comprehensive guide for individuals who need to obtain (or renew) their ITIN, providing clarity on the process, clearing up misconceptions, and showcasing the invaluable assistance of an experienced lawyer like William Quirk.  

What Is an ITIN and Why Is It Important?

An ITIN is a tax processing number issued by the Internal Revenue Service (IRS). It is a nine-digit number that begins with the number nine and is formatted like a Social Security Number (9XX-XX-XXXX).  

The primary purpose of an ITIN is to provide non-resident or resident aliens, and other individuals who are required to have a U.S. taxpayer identification number, a way to efficiently process returns and to comply with the U.S. tax laws. 

For immigrants, an ITIN is vital for a variety of reasons, including filing taxes and opening a bank account. Without an ITIN, access to these basic financial services is significantly limited, complicating an individual's financial management and compliance with U.S. tax laws. 

Who Needs an ITIN?

Not every immigrant or non-citizen requires an ITIN. However, if you fall into one of the following categories, you are likely in need of an ITIN: 

  • A non-citizen who needs to file a U.S. tax return. 

  • A non-citizen required to file a U.S. tax return. 

  • A dependent or spouse of a U.S. citizen or resident alien. 

  • A dependent or spouse of a non-resident alien visa holder. 

  • A non-citizen committed to conducting business in the U.S. 

If any of these criteria apply to you, obtaining an ITIN should be a priority to ensure your compliance with U.S. tax laws. 

How to Apply for an ITIN

Obtaining an ITIN can be a straightforward process if approached correctly. The first step is to collect all necessary documents, including your completed W-7 Form, which is the application for an IRS ITIN, and originals or certified copies of required identification documents. 

The W-7 application must be submitted along with a current tax return form. 

It's important to make sure all documents are correct, as errors or missing information can delay the application process. Once your application is ready, you can submit it by mail or in person through an IRS-authorized acceptance agent or at an IRS Taxpayer Assistance Center. 

Benefits of Having an ITIN 

Having an ITIN can provide several benefits, beyond just compliance with tax laws. These include: 

  • The ability to file taxes and potentially claim a refund, which can lead to significant financial benefits for some immigrants. 

  • The opportunity to open savings, checking, and other investment accounts to manage personal or business finances. 

  • The ability to apply for a mortgage to purchase a home or other loans to pursue educational or business opportunities. 

  • The ability to receive sales tax refunds in certain states. 

Common Misconceptions 

There are several misconceptions surrounding ITINs that immigrants should be aware of. 

  • An ITIN does not grant the right to live or work in the United States. 

  • An ITIN is not proof of a person’s immigration status. 

  • ITIN filers may or may not be eligible for Social Security benefits, and having an ITIN does not necessarily affect eligibility. 

ITIN vs. Social Security Number (SSN): Understanding the Differences

A common point of confusion among immigrants and non-citizens in the U.S. revolves around the differences between an Individual Taxpayer Identification Number (ITIN) and a Social Security Number (SSN). Though they may appear similar, serving as unique identifiers within the U.S. system, their purposes, eligibility requirements, and implications for holders differ significantly. 

  • Purpose: The SSN is primarily issued to U.S. citizens, permanent residents, and temporary (working) residents under the Social Security Administration to track individuals for social security and other government benefits. An ITIN, on the other hand, is issued by the Internal Revenue Service (IRS) specifically to individuals who are required to file a tax return but are not eligible for a SSN, such as non-resident and resident aliens. 

  • Eligibility: To be eligible for an SSN, an individual must be a U.S. citizen or have permission from the Department of Homeland Security to work in the U.S. The ITIN is available to those who do not meet these criteria but still need to file a U.S. tax return, ensuring that individuals can comply with tax laws without suggesting or providing work authorization. 

  • Implications: Holding an SSN can imply eligibility to work, as well as access to social security benefits and other government services. In contrast, the ITIN does not provide work authorization, nor does it offer benefits or legal immigration status. The ITIN allows individuals to comply with tax laws and access some financial services, like banking. 

Understanding the distinctions between an ITIN and an SSN is crucial for immigrants navigating their financial and legal obligations in the U.S. While both play pivotal roles in the U.S. administrative system, their specific functions cater to distinct groups with different needs and legal statuses. 

Having a clear understanding of the purpose of an ITIN is key to avoiding any misunderstanding and potential fraud. 

Renewing Your ITIN

To ensure the proper function of the tax administration process, the IRS implemented an ITIN renewal process under the PATH Act. Renewal is needed if it has not been used on a tax return in three years. 

Renewal requires submitting a Form W-7, along with your original identification documents. If you fail to renew your ITIN when required, you may not be able to claim certain tax benefits and may result in refund delays and a denial of the right to claim specific tax credits.
