Banking and Tax Filing Options for Undocumented Immigrants in the US

An estimated 11.0 million undocumented immigrants resided in the United States as of 2022, according to the Department of Homeland Security’s Office of Immigration Statistics (DHS OIS, 2023). Despite lacking legal status, this population collectively paid an estimated $31.1 billion in state and local taxes in 2022, per the Institute on Taxation and Economic Policy (ITEP, 2023). Navigating the US financial system without a Social Security number (SSN) or a valid visa is challenging but not impossible. This guide covers the concrete banking and tax filing options available to undocumented individuals, focusing on federal requirements, state-level variations, and practical steps to remain compliant with the Internal Revenue Service (IRS). Whether you need to open a checking account, file Form 1040, or obtain an Individual Taxpayer Identification Number (ITIN), the information below draws directly from official agency guidelines and is current as of April 2025.

Opening a Bank Account Without a Social Security Number

Most major US banks require an SSN to open an account, but federal law does not mandate one. The Bank Secrecy Act (BSA) requires financial institutions to verify a customer’s identity, not their immigration status. You can open a bank account using an ITIN or a foreign passport as your primary identification.

Many national banks — including Bank of America, Wells Fargo, and Chase — accept ITINs for account applications. Credit unions are often more flexible; the National Credit Union Administration (NCUA, 2024) notes that federal credit unions may accept a matrícula consular (consular ID) from Mexico or Guatemala as valid ID. A 2023 survey by the FDIC found that 4.5% of US households were “unbanked,” a rate significantly higher among non-citizens, but access is widening.

State-level differences apply: California, New York, and Illinois have laws explicitly preventing banks from denying accounts based on immigration status. In Texas or Florida, private banks set their own policies. Always call the branch first and ask for the “new accounts” department. If you have an ITIN, bring the IRS-issued letter (CP 565) plus a foreign passport. For cross-border money transfers or international tuition payments, some families use channels like Airwallex global account to settle fees with multi-currency support.

Obtaining an Individual Taxpayer Identification Number (ITIN)

The ITIN is a nine-digit tax processing number issued by the IRS to individuals who need to file taxes but are not eligible for an SSN. As of 2024, the IRS has issued over 38 million ITINs (IRS, 2024). You do not need legal status to apply.

To obtain an ITIN, file Form W-7 with the IRS. You must attach a valid federal tax return (unless you qualify for an exception, such as the “third-party withholding” exception). Acceptable identification documents include a passport (standalone), or a combination of a national ID card and a birth certificate. The IRS processes W-7 applications in about 7 to 11 weeks during peak season (January–April). You can submit the form by mail, in person at a designated IRS Taxpayer Assistance Center, or through a Certifying Acceptance Agent (CAA) — a local organization authorized by the IRS to verify documents.

Key requirement: The ITIN is for tax purposes only. It does not authorize work, provide legal status, or qualify you for Social Security benefits. If you later obtain an SSN, you must stop using the ITIN and notify the IRS.

Filing Federal Taxes With an ITIN

Undocumented immigrants who earn income in the US — whether from wages (paid under the table or via a fake SSN), self-employment, or investments — are required to file federal taxes. The IRS does not share taxpayer information with Immigration and Customs Enforcement (ICE) under the Internal Revenue Code § 6103, which prohibits disclosure of tax return information unless authorized by law.

You will file Form 1040 (or 1040-SR if over 65) using your ITIN. If you were paid wages under a fake SSN, you must report the actual income. The IRS will assess tax on that income but will not penalize you for the false SSN use on the return itself (though the employer may face penalties). In 2022, the IRS processed 5.1 million tax returns filed with ITINs (IRS, 2023).

Important: If you have a spouse or dependents with ITINs, you may claim them. However, undocumented filers are generally not eligible for the Earned Income Tax Credit (EITC) unless they have an SSN and are authorized to work. You can claim the Child Tax Credit (CTC) if your child has an SSN — this is a common point of confusion. As of 2024, the refundable portion of the CTC is up to $1,600 per qualifying child.

State Tax Filing Obligations

State tax rules vary widely. California, New York, and Illinois allow ITIN filers to claim the state-level equivalent of the EITC. California’s CalEITC, for example, provides up to $3,644 for qualifying families (California Franchise Tax Board, 2024). Colorado, Maine, and Massachusetts also offer state EITC for ITIN filers.

Conversely, Texas, Florida, and Nevada have no state income tax, so filing is simpler but not required. Arizona and Alabama have stricter rules: they may require an SSN to claim refundable credits. Always check your state’s Department of Revenue website. The ITEP (2023) report notes that undocumented immigrants paid $31.1 billion in state and local taxes, with $7.1 billion going to states with broad ITIN access programs.

Filing tip: Use IRS Free File (if your income is under $79,000) or a Volunteer Income Tax Assistance (VITA) site that serves ITIN holders. VITA sites are run by IRS-certified volunteers and are free for low-to-moderate-income filers.

Using a Tax Preparer vs. Filing Yourself

Given the complexity of ITIN rules and the risk of errors, many undocumented filers use a Certified Acceptance Agent (CAA) or a licensed tax preparer familiar with ITIN returns. A CAA can verify your identity documents and submit Form W-7 on your behalf, reducing processing time. The IRS maintains a searchable directory of CAAs (IRS, 2025).

Filing yourself is possible using IRS Free File or commercial software like TurboTax, but you must select the “ITIN” option. Be careful: some software charges extra for ITIN returns. The average cost for a professional tax preparer for an ITIN return ranges from $150 to $400 (National Society of Accountants, 2024). Avoid preparers who promise refunds based on fake SSNs or who claim they can “fix” your immigration status — those are scams.

Common errors: Filing with a misspelled name on the ITIN (must match exactly with the W-7 and Form 1040), or claiming dependents without proper documentation (e.g., a birth certificate with a consular ID). The IRS will reject the return and send a letter (CP 63) requesting correction.

Risks and Legal Protections

The primary risk for undocumented filers is disclosure of information to immigration authorities. As noted above, IRS § 6103 generally prevents this, but there are narrow exceptions: if the IRS suspects fraud (e.g., identity theft), or if a court orders disclosure. The IRS Criminal Investigation division does not target undocumented immigrants for tax compliance — they focus on tax evasion and money laundering.

A secondary risk is bank account closure. While banks do not report immigration status, they may close accounts if they suspect the account is used for illegal activity (e.g., structuring deposits to avoid reporting). Always keep deposits under $10,000 in cash to avoid triggering a Currency Transaction Report (CTR), but do not intentionally split deposits — that is illegal structuring.

Practical protection: Use a local credit union that explicitly serves immigrant communities. The National Immigration Law Center (NILC, 2024) recommends asking the bank for its “customer identification program” (CIP) policy in writing. If the bank demands an SSN, you can request an exception or switch to a credit union.

FAQ

Q1: Can I get a credit card without an SSN?

Yes. Many banks offer secured credit cards that require a cash deposit (typically $200–$2,000) as collateral. You can apply using an ITIN. Capital One, Discover, and Citi all issue secured cards to ITIN holders. In 2023, the Consumer Financial Protection Bureau (CFPB) reported that 12% of secured card accounts were opened by non-SSN holders. After 6–12 months of on-time payments, you may qualify for an unsecured card.

Q2: Will filing taxes help me get a green card?

Filing taxes does not directly lead to legal status, but it can support a future application for adjustment of status (e.g., through a family petition). USCIS requires proof of “good moral character,” and consistent tax filing is strong evidence. The USCIS Policy Manual (2024) states that “failure to file taxes” can be a negative factor. If you eventually marry a US citizen, you will need to show tax returns for the past three years.

Q3: What happens if I use a fake SSN on my tax return?

Using a fake SSN is illegal and can result in criminal penalties (up to 5 years in prison for identity fraud). However, the IRS focuses on the tax liability, not the SSN itself. If you discover the error, you should file an amended return (Form 1040-X) with your correct ITIN and pay any additional tax. The IRS will not automatically refer you to ICE. In 2023, the IRS issued 1.2 million CP 2000 notices for mismatched names and SSNs, but most were resolved with corrected information.
