Opening a bank account or applying for a loan in the United States can be difficult for people who do not have a Social Security Number (SSN). Many immigrants, non-citizens, and international students face this challenge each year. To help, the Internal Revenue Service (IRS) issues an Individual Taxpayer Identification Number (ITIN). This tax identification number is given to eligible applicants who cannot receive an SSN from the Social Security Administration but must file tax returns, report income, or meet other tax purposes.

The ITIN plays a vital role in daily financial life. With it, taxpayers can open checking or savings accounts at banks, establish a credit history, and sometimes qualify for financing such as mortgages. While the IRS clarifies that the ITIN does not authorize work or grant Social Security benefits, it is still critical for people who must file a federal income tax return, pay taxes, and verify eligibility for banking services.

In this guide, you will learn how the ITIN works, who can apply, and the complete process for submitting an ITIN application. We will also cover ITIN renewal, required documentation such as a passport or driver’s license, and how IRS Taxpayer Assistance Centers and Certifying Acceptance Agents can help. Practical examples will show how students, dependents, or property owners use ITINs to file federal tax returns, claim benefits, and manage funds. 

What Is an Individual Taxpayer Identification Number

An Individual Taxpayer Identification Number (ITIN) is a nine-digit tax identification number issued by the Internal Revenue Service (IRS). It is for people who must file tax returns or report income but cannot receive a Social Security Number (SSN) from the SSA. ITINs help taxpayers without SSNs comply with federal tax laws. However, the IRS clarifies that an ITIN does not replace an SSN and does not provide broader government benefits. Specifically, an ITIN does not:

  • Authorize work in the United States: Having an ITIN does not grant work authorization or earned income eligibility.

  • Provide Social Security benefits: The number cannot be used to access retirement, disability, or other SSN-based benefits.

  • Change immigration status: The ITIN is strictly for tax administration and does not affect immigration eligibility or applications.

  • Serves as general identification: Outside of tax and certain financial processes, it cannot be used as official ID.

The ITIN format mirrors that of the SSN, but with key differences. Every ITIN begins with the number 9, and the fourth and fifth digits fall within ranges assigned by the IRS. While it looks similar to an SSN, its sole purpose is to help taxpayers meet filing obligations and access limited financial services.

Who Needs an ITIN for Banking and Loans

The Internal Revenue Service (IRS) issues ITINs to a wide range of people who are ineligible for a Social Security Number but must file tax returns or meet other tax purposes. Beyond tax compliance, these individuals often use the number to access banking services, verify identity, and qualify for loans or financing. The following groups commonly require an ITIN:

  • Nonresident aliens: Many non-citizens living outside the United States must still report income or file federal income tax returns if they receive U.S. income. Nonresident aliens may also need an ITIN to claim treaty benefits or manage property held in the country. For these taxpayers, the ITIN is the only way to meet IRS requirements and interact with banks that request a tax identification number.

  • Resident aliens who do not qualify for an SSN: Some residents meet the substantial presence test but remain ineligible for an SSN due to their visa status. In these cases, the ITIN allows them to file tax returns, report earned income, and maintain compliance. It also provides the documentation they need to open checking or savings accounts.

  • Spouses and dependents of U.S. citizens or residents: A spouse or dependent who cannot obtain an SSN may need an ITIN to be included on a joint federal tax return or to claim certain benefits. With an ITIN, they can be listed properly for tax purposes, and in many cases, it also helps establish a financial identity when banks request verification.

  • Foreign students, professors, and researchers: International students on F, J, or M visas, as well as visiting professors and researchers, are often required to file tax returns even if they are ineligible for an SSN. The ITIN gives them a valid way to meet this obligation. It also supports common financial needs such as opening a bank account near a university, paying rent, or handling scholarship funds.

For each of these groups, the ITIN is a tool for tax compliance and a bridge to basic financial services. Without it, many applicants would be unable to submit required forms, prove eligibility, or access secure banking.

Banking and Loan Applications with an ITIN

Although the Individual Taxpayer Identification Number (ITIN) is issued strictly for tax purposes, it is widely accepted by banks, credit unions, and some lenders. An ITIN allows applicants ineligible for a Social Security Number (SSN) to access essential financial services, from opening checking accounts to applying for mortgages.

Bank Account Opening

The Consumer Financial Protection Bureau notes that banks and credit unions may accept an ITIN instead of an SSN when verifying identity. This allows non-citizens, international students, and other ineligible taxpayers to establish accounts and manage funds.

Most banks require applicants to provide specific documents in addition to their ITIN. These typically include:

  • Valid ITIN documentation: A copy of the IRS assignment notice (Form CP-565) or other official proof that the IRS issued the number.

  • Government-issued photo identification: This can be a passport, driver’s license, or national identification card that confirms identity.

  • Proof of address: A utility bill, lease agreement, or university housing document is usually acceptable.

  • Initial deposit: Some banks require a minimum payment to activate the account, with amounts varying by institution.

By presenting these documents, applicants can meet verification rules, open accounts, and build a financial history in the United States.

Loan and Mortgage Eligibility

Some lenders offer financing programs specifically for people with ITINs. While these programs expand opportunities for applicants who cannot qualify with an SSN, they often come with stricter conditions. Borrowers should be prepared for:

  • Higher down payments: Lenders may require a larger upfront payment to reduce risk when the applicant uses an ITIN rather than an SSN.

  • Higher interest rates: Mortgage and loan programs for ITIN holders may carry higher rates than traditional financing.

  • Additional documentation of income and assets: Applicants are often required to provide pay stubs, tax returns, or other forms of proof to verify that they can manage payments.

  • Longer processing times:  Because lenders must carefully review eligibility and documentation, ITIN loan applications can take longer to complete.

For many taxpayers, these programs still represent a valuable opportunity. With the proper documentation and financial preparation, ITIN holders can open accounts and pursue financing for property, education, or other long-term goals.

How to Apply for an ITIN

Applying for an Individual Taxpayer Identification Number (ITIN) requires careful preparation. The Internal Revenue Service (IRS) outlines a process that ensures eligibility is verified, documents are complete, and applications are properly submitted. Following each step closely helps avoid delays and increases the chances of approval.

Step 1: Determine Eligibility

The IRS issues ITINs to people who must file a federal income tax return or report income but cannot obtain a Social Security Number (SSN). You may qualify if you are a non-U.S. citizen with U.S. income, an international student, a dependent or spouse listed on a federal tax return, or a property owner who needs to pay taxes. Because ITINs are strictly for tax purposes, they do not provide work authorization or Social Security benefits.

Step 2: Gather Required Documentation

Applicants must submit original or certified copies of documents that establish both identity and foreign status. A valid passport is a stand-alone document, but alternatives include a driver’s license, national identification card, or birth certificate for dependents. Proof of U.S. residency, such as school or medical records, may also be required for children. Ensuring documents are consistent, unexpired, and accurate is critical to prevent rejection.

Step 3: Complete Form W-7

Form W-7 is the official ITIN application and requires applicants to provide personal information, select a reason for applying, and sign the form. Careful attention is necessary when filling out each field because errors in names, dates, or eligibility details often cause processing delays. Applicants should clearly indicate whether they are requesting a new ITIN or submitting an ITIN renewal if their number has expired.

Step 4: Submit Application Package

Once the form and documents are complete, the package can be submitted by mail, in person, or through acceptance agents. Mailing the application to the IRS ITIN Operations unit in Austin, Texas, is common for international applicants. Those inside the U.S. may choose an IRS Taxpayer Assistance Center. At the same time, Certified Acceptance Agents can review documents, verify identity, and send applications directly to the IRS, allowing applicants to retain their originals.

Step 5: Understand Processing Times

Standard processing takes about seven weeks, though applications filed during peak tax season or from abroad may require nine to eleven weeks. The IRS may send a notice if additional documentation is needed, and applicants should respond quickly to prevent further delays. Keeping copies of all submitted documents and noting the submission date helps track progress until the IRS issues confirmation.

ITIN Renewal: Deadlines and Process

An ITIN does not last forever. The Internal Revenue Service (IRS) requires taxpayers to renew expired numbers before filing a federal tax return, ensuring that income can be reported accurately and without delays. Understanding when renewals are necessary and how to complete them helps taxpayers stay compliant.

Step 1: Determine If Renewal Is Necessary

An ITIN expires if it has not been used on a federal tax return for three consecutive years or was issued before 2013 and has not yet been renewed. Taxpayers should check the expiration date carefully because an expired ITIN cannot be used to file returns, claim dependents, or receive certain tax benefits. Renewal is only required if the ITIN will appear on a current federal tax return.

Step 2: Complete Form W-7 for Renewal

To renew, applicants must file Form W-7, selecting the box for “Renew an Existing ITIN.” The form must include the current ITIN and personal information such as name, date of birth, and address. Providing accurate details is important, as document inconsistencies or prior IRS records may lead to delays or rejection.

Step 3: Submit Renewal Application and Documentation

The renewal package includes Form W-7, proof of identity, and supporting documentation that confirms foreign status. Unlike the original application, a federal tax return is not always required unless the IRS specifies otherwise. Taxpayers may submit by mail, visit an IRS Taxpayer Assistance Center, or use Certified Acceptance Agents who verify documents and forward applications directly. Renewing early, before the tax filing season, helps ensure the process is complete before a return must be filed.

Becoming a Certified Acceptance Agent (CAA)

Certified Acceptance Agents (CAAs) are important in helping people apply for or renew an Individual Taxpayer Identification Number (ITIN). They are authorized by the Internal Revenue Service (IRS) to verify documents and submit applications on behalf of taxpayers, reducing the need to mail original records.

Eligibility

The IRS allows tax professionals, universities, banks, and community organizations to become acceptance agents. These applicants must pass suitability checks to confirm their qualifications.

Benefits

  • Streamlined process. CAAs can verify passports, driver’s licenses, and other documents directly, which allows applicants to keep their originals instead of mailing them.

  • Faster service. By reviewing forms in advance, CAAs help reduce errors and improve the chances that the IRS issues an ITIN without delays.

Application and Training

  • IRS requirements. To become a CAA, organizations must complete IRS training, submit an application through IRS e-Services, and agree to follow program rules.

  • Ongoing compliance. Acceptance agents must maintain records, meet annual standards, and remain authorized by the IRS to continue offering these services.

Using a CAA can make the ITIN application or renewal process smoother, especially for applicants worried about mailing sensitive documents.

Practical Examples and Common Scenarios

Immigrant Parent with Dependents

An immigrant from Mexico needs to file a federal income tax return and claim their dependents. They apply for an ITIN using Form W-7, provide passports for themselves and their children, and submit school records as proof of residency. With their IRS-issued ITIN, they can file tax returns correctly and open a bank account to manage family funds.

Foreign Student with Fellowship Income

A graduate student from China receives fellowship income while studying at a U.S. university. Because he is ineligible for a Social Security Number (SSN), he must apply for an ITIN to report income and file tax returns. Once approved, his ITIN allows him to open a checking account, pay rent more easily, and establish credit during his stay.

Nonresident Investor with U.S. Property

A non-resident lives in Dubai and owns a rental property in the United States. To report rental income and pay federal taxes, he applies for an ITIN through the IRS. After approval, he can file returns annually and use the ITIN to open a U.S. bank account dedicated to property income and expenses, making it easier to manage payments and verify funds.

Common ITIN Issues and Solutions

Application Rejections

The IRS may reject an ITIN application if the form is incomplete, documents are missing, or the applicant does not meet eligibility requirements. Applicants who receive a CP567 notice should carefully review the listed errors, correct them, and resubmit the package. Using Certified Acceptance Agents can also help reduce mistakes and improve approval rates.

Name Changes

If a person changes their name due to marriage, divorce, or a legal order, they must notify the IRS to update their ITIN records. Submitting proof, such as a marriage certificate or court order, ensures the information matches federal tax return filings and prevents delays in processing.

Transitioning from ITIN to SSN

When a taxpayer becomes eligible for a Social Security Number, the ITIN should no longer be used. The individual must contact the IRS, provide the ITIN assignment notice and the new SSN card, and update records with banks and employers. This step helps prevent duplicate accounts and ensures tax payments are properly credited.

Lost or Stolen Documents

Applicants sometimes lose critical documents such as passports or IRS assignment notices. In these cases, they should contact the issuing agency or the IRS to request replacements. Having certified copies made before submitting documents can also provide backup in case of loss.

Banking Guidelines for ITIN Holders

Using an Individual Taxpayer Identification Number (ITIN) to open accounts or apply for financing requires preparation and awareness. Banks and credit unions set their own rules, so it is essential to research policies before applying. 

Applicants should also gather the proper documents, such as a passport, driver’s license, and proof of address, to verify identity and eligibility. Below are key guidelines that can help ITIN holders succeed in banking:

  • Confirm ITIN acceptance: Not every bank accepts an ITIN for account opening, so applicants should check policies in advance to avoid wasted time.

  • Understand documentation requirements: Institutions often ask for more than the ITIN itself, such as a government-issued ID and proof of residence, to verify identity.

  • Prepare for deposit rules: Many banks require an initial payment or minimum deposit, so applicants should be ready to provide funds when setting up an account.

  • Review fees carefully: Service fees, ATM charges, and maintenance costs can add up, making it important to compare different institutions.

  • Ask about credit-building options: Some banks offer secured credit cards or financing programs that help ITIN holders establish and grow credit history in the United States.

By following these guidelines and preparing thoroughly, ITIN holders can choose financial institutions that best support their goals, from managing funds securely to building long-term credit.

Risks of Ignoring ITIN Requirements

Failing to obtain or renew an ITIN can cause tax problems. The IRS needs accurate, timely filings, and an expired or missing ITIN can cause issues. Without it, taxpayers risk penalties, interest, and refund delays. Incomplete filings may limit claiming dependents or benefits. Ignoring ITIN rules can also block access to financial services. 

Banks may refuse to open accounts without a valid ITIN, and most lenders require it to process financing applications. Without it, applicants face higher fees, limited services, and credit issues, which can affect their financial stability.

When to Seek Professional Help

Applying for, renewing, or correcting an Individual Taxpayer Identification Number (ITIN) can complicate certain situations. When challenges arise, working with a qualified professional helps ensure the process is handled correctly and in compliance with Internal Revenue Service (IRS) requirements.

  • Certified Public Accountants (CPAs): A CPA can guide applicants through filing federal income tax returns, verify documentation, and explain how ITINs affect eligibility for certain tax benefits.

  • Enrolled Agents (EAs): EAs are federally authorized tax professionals who represent taxpayers before the IRS and can assist with ITIN-related filings and appeals.

  • Certified Acceptance Agents (CAAs): The IRS authorizes CAAs to verify identity documents and submit ITIN applications on behalf of clients, reducing the need to mail originals.

  • Tax Attorneys: For complex cases involving immigration status, property ownership, or disputes with the IRS, tax attorneys provide legal representation and advice.

  • Community Resources: Some universities, nonprofit organizations, and Low Income Taxpayer Clinics (LITCs) offer free or low-cost assistance with ITIN applications for eligible taxpayers.

By contacting the right professional, applicants can resolve issues more efficiently, avoid delays, and ensure their ITIN is properly filed or renewed.

Important Disclaimers and Legal Considerations

  • Educational purposes only: Information about the Individual Taxpayer Identification Number (ITIN) is provided for general education and should not be considered legal, tax, or immigration advice.

  • Verify with official sources: Every situation is different, and IRS regulations may change from year to year. Before submitting forms or documentation, applicants should confirm details through official Internal Revenue Service (IRS) publications.

  • Tax purposes only: The ITIN does not authorize employment, provide Social Security benefits, or change immigration status. Its sole purpose is to help taxpayers file tax returns and report income.

  • IRS authority: Only the IRS can issue or renew an ITIN, and the rules regarding eligibility, documentation, and renewal may shift as policies are updated.

  • Professional guidance: Consulting with qualified professionals helps ensure applications are completed accurately and that taxpayers remain compliant with current regulations.

Next Steps and Call to Action

Taking action with an Individual Taxpayer Identification Number (ITIN) ensures compliance with tax rules and improves access to financial services. Applicants can move forward by following these steps:

  • Assess eligibility: Review IRS guidelines to confirm whether you qualify for an ITIN based on your need to file tax returns, report income, or be listed as a dependent or spouse.

  • Gather documentation: Collect the required documents, such as a valid passport, driver’s license, or proof of U.S. residency, and make sure they are current and consistent.

  • Complete Form W-7: Please complete the application carefully, choosing the correct reason for applying or renewing, and checking that all information matches your supporting documents.

  • Submit the package: You can mail your application, deliver it to an IRS Taxpayer Assistance Center, or work with Certified Acceptance Agents who can verify documents and forward them.

  • Track progress: Keep copies of your submission, note the date sent, and respond promptly if the IRS contacts you for additional information.

By following these steps, applicants can confidently apply for or renew their ITIN and prepare to use it for banking, financing, and tax purposes.

Frequently Asked Questions

Can I use my ITIN to apply for a credit card?

Many banks and financial institutions accept an Individual Taxpayer Identification Number (ITIN) instead of a Social Security Number (SSN) for credit card applications. Approval usually depends on credit history, income, and other eligibility factors. Using an ITIN to apply helps non-citizens and international students start building credit and gain access to U.S. financing opportunities.

How long does an ITIN remain valid?

An ITIN remains valid as long as it is used on a federal income tax return at least once every three years. If it has not been used for that period, it will expire. Taxpayers should renew promptly before filing to avoid issues with reporting income, claiming dependents, or submitting a tax return on time.

Do all banks accept ITINs when opening accounts?

Not all banks or credit unions accept ITINs, but many do. Each institution sets its own policies for account eligibility, including documentation requirements. Applicants should verify acceptance beforehand and be prepared with proof such as a passport, driver’s license, and IRS-issued ITIN notice. Confirming acceptance saves time and ensures funds can be deposited securely.

Can I use my ITIN to apply for a mortgage or loan?

Yes, some lenders provide special financing programs for ITIN holders, but terms are often stricter. Borrowers may face higher down payments, higher interest rates, and additional requests for documentation of income and assets. Using an ITIN for loan eligibility can still be valuable, especially for taxpayers without SSNs who want to purchase property or access credit.

How do I check the status of my ITIN application?

To check the status of your ITIN application, you can contact the IRS directly by phone. Domestic applicants may call the IRS helpline, while international applicants can use the dedicated international number. It is best to wait until after the standard processing timeline before checking. Be ready to provide identifying information to verify your request.

What happens if my ITIN application gets rejected?

If the IRS rejects your ITIN application, it will issue a CP567 notice explaining why. Common reasons include missing documents, expired identification, or an incomplete Form W-7. To correct the issue, applicants should carefully review the notice, gather the required documentation, and resubmit. Certified Acceptance Agents can also help verify identity and reduce rejections in future submissions.

Is there a fee for applying for or renewing an ITIN?

The IRS does not charge a fee for applying for or renewing an ITIN. However, some Certified Acceptance Agents or tax professionals may charge service fees for assisting with the process. Applicants should note that using a CAA is optional. Whether filing by mail or through an IRS Taxpayer Assistance Center, the application itself remains free.
