Understanding the importance of an ITIN for undocumented immigrants is essential, as it paves the way for tax filing and other financial activities within the United States. It’s crucial to recognize that, although it does not provide any legal status, this number can significantly facilitate daily financial operations and responsibilities.
As undocumented immigrants navigate their lives in the U.S., obtaining an ITIN becomes a key step in ensuring their tax affairs are in order. The process might seem daunting, but knowledge about ITINs is power, easing the way towards compliance with the U.S. tax system and opening doors to other benefits.

What Is an ITIN?
An Individual Taxpayer Identification Number, or ITIN, is a tax processing number issued by the Internal Revenue Service (IRS). It’s a nine-digit number that enables individuals without Social Security Numbers (SSNs), including undocumented immigrants, to comply with U.S. tax laws. The ITIN allows the IRS to efficiently process and account for tax returns and payments for those who may not be eligible for an SSN.
While it is primarily used for tax filing purposes, an ITIN can also be used to open a bank account or apply for a mortgage. However, it’s important to note that an ITIN does not confer a legal immigration status and is not a work permit.
Why Do Undocumented Immigrants Need an ITIN?
One might wonder why undocumented immigrants would need an ITIN. The answer lies in the responsibility and benefits that come with tax filing. Paying taxes is a legal requirement for everyone earning an income within the U.S., regardless of their immigration status. By using an ITIN, undocumented immigrants can fulfill their tax obligations, which may later demonstrate good moral character in immigration proceedings.
Moreover, having an ITIN allows individuals to claim the Child Tax Credit for their eligible dependent children, which can significantly reduce their tax liability or increase their refund.
How to Apply for an ITIN Number
The application process for an ITIN begins with completing IRS Form W-7. This form requires applicants to provide proof of identity and foreign status, usually through a passport or a combination of other documents. Applicants must also attach a valid federal income tax return unless they meet an exception.
The completed form and supporting documents can be submitted to the IRS either by mail or in person at an IRS-designated acceptance agent. In some cases, applicants may be eligible for assistance through community programs or non-profit organizations.
When Should I Renew My ITIN?
ITINs do have an expiration date, and it is important to renew them to avoid delays in tax returns and refunds. ITINs that have not been used on a federal tax return at least once in the last three consecutive tax years will expire. Moreover, ITINs with middle digits 88 and numbers with the middle digits 90 through 99, if assigned before 2013, also need to be renewed.
The renewal process is similar to the initial application, requiring individuals to fill out Form W-7 and submit the necessary documentation.
Does an ITIN Offer Legal Status or Work Rights?
It’s a common misconception that an ITIN can change an individual’s immigration status or provide the right to work in the U.S. However, the truth is that an ITIN is solely a tax processing number. It does not provide legal status, work authorization, or eligibility for Social Security benefits. Its purpose is strictly to ensure that everyone pays their fair share of taxes, regardless of their immigration status.
Which Banks Accept ITINs for Accounts?
Many banks and credit unions accept ITINs as part of their identification requirements for opening accounts. This allows undocumented immigrants to securely manage their finances, save money, and establish a credit history. However, it’s advisable to check with individual financial institutions for their specific policies regarding ITINs.

Frequently Asked Questions on ITINs
How Can a Non-US Citizen Get an ITIN Number?
To obtain an ITIN, a non-US citizen needs to complete Form W-7 and provide necessary documentation, such as a passport or a combination of other identification proofs. This can be submitted along with a tax return during the tax filing season or independently if the individual meets an exception.
It’s important to ensure that all documents are accurate and submitted correctly to avoid unnecessary delays. The IRS provides detailed instructions and a list of acceptable documents to assist applicants in the process.
Can You Legally Work in the US With an ITIN Number?
An ITIN does not provide the right to work in the United States. It is not a substitute for a Social Security Number (SSN) and does not authorize an individual to work or claim work-related tax benefits. Employers must verify that their employees have the proper work authorization, typically in the form of an SSN.
Using an ITIN to work illegally can lead to severe legal consequences, and employers could face penalties for hiring individuals without proper authorization.
How to Merge ITIN and SSN?
If an individual obtains a Social Security Number (SSN) after having an ITIN, they should stop using the ITIN and use the SSN instead. The individual should contact the IRS to inform them of the change and ensure that their tax records are combined under their SSN. This helps maintain a consistent tax history.
It is critical to notify the IRS immediately upon receiving an SSN to avoid complications with tax returns and legal issues that may arise from using both numbers.
How Do I Verify My ITIN Number?
To verify an ITIN, individuals can call the IRS’s ITIN Hotline at 1-800-908-9982. They may need to provide personal information and answer security questions to confirm their identity. The IRS can also provide guidance on any issues related to an ITIN, such as renewal or status queries.
Ensuring that an ITIN is current and valid is crucial for tax filing purposes and avoiding delays with tax refunds or processing.
In conclusion, while an ITIN number for illegal immigrants does not change one’s immigration status or provide work rights, it plays a vital role in ensuring compliance with tax obligations and offers financial benefits. It is a valuable asset for undocumented immigrants living in the U.S., facilitating their ability to engage in legal financial activities and demonstrating fiscal responsibility.
