Language Barriers in Tax Filing: When the IRS Speaks English Only

Millions of LEP immigrant workers — including undocumented individuals filing with ITINs — pay taxes every year. The tax code, IRS correspondence, audit notices, and most tax preparation services are English-first, leading to missed credits, filing errors, and audit vulnerability for some of America's most economically vulnerable workers.

Tax filing is a civic obligation that touches nearly every working adult in the United States. For LEP immigrants — including the millions who work legally on visas, the millions with green cards, and the estimated 11 million undocumented individuals many of whom pay taxes using Individual Taxpayer Identification Numbers — this obligation must be met in a system built primarily in English. The tax code is notoriously complex for native English speakers with college degrees. For someone navigating it in a second language, with limited formal education, and often with anxiety about immigration consequences of any interaction with the government, the complexity is compounded at every level.

The consequences of the language gap in tax filing are real and measurable: missed refunds and credits that could provide meaningful financial relief; filing errors that create IRS correspondence the filer cannot understand; vulnerability to unscrupulous tax preparers who exploit language gaps; and for some, audit notices they cannot respond to effectively, leading to penalties on amounts that could have been resolved with proper communication.

Who Pays Taxes Without a Social Security Number

A common misconception about undocumented immigrants is that they do not pay taxes. The reality is more complex. Many undocumented workers are employed in jobs where payroll taxes — Social Security and Medicare — are withheld from wages, often using Social Security numbers obtained under varying circumstances. Others file taxes using Individual Taxpayer Identification Numbers (ITINs), a tax processing number the IRS issues specifically for individuals not eligible for Social Security numbers.

The Institute on Taxation and Economic Policy has estimated that undocumented immigrants pay approximately $11.7 billion annually in state and local taxes — sales taxes, property taxes (directly or through rent), and income taxes. Federal income taxes through ITIN filers add to this total. The motivation to file includes: legal requirement to report income, desire to establish a tax compliance record that may be relevant to future immigration proceedings, and in some cases eligibility for refunds of over-withheld wages.

The ITIN process

Obtaining an ITIN requires completing IRS Form W-7, submitting certified copies of identity documents (passport, national identity card, or other accepted documents), and either filing a return with the application or meeting one of several exception categories. The process is entirely in English. Errors in the application — wrong box checked, insufficient documentation, incorrect exception claimed — result in rejection and delay, often requiring correspondence with the IRS that is conducted in English.

"I applied for my ITIN three times. Each time the IRS sent back a letter saying something was wrong. I couldn't read the letter. My neighbor would help me understand a little, but she didn't know what 'certified copy' meant either. Finally a community organization helped me. It took eight months." — ITIN applicant recounting the process

IRS Forms and Publications: The English Default

The IRS has made meaningful, if incomplete, progress on language access. Key publications — the 1040 instructions, Publication 17 (the general tax guide) — are available in Spanish. The IRS website offers some content in Spanish, Chinese, Korean, Russian, Vietnamese, and Haitian Creole. The IRS Free File program has been offered in Spanish for certain providers.

But the full scope of IRS communication is predominantly English-only. IRS notices — the letters that inform taxpayers of discrepancies, request additional information, initiate audits, propose additional tax, or begin collection — are issued in English. A taxpayer who has indicated Spanish as their preferred language may still receive an audit notice in English. The notice typically has a 30-day response deadline and a specific set of instructions for providing substantiating documentation. An LEP filer who cannot read the notice may not understand they have received it, may not know they need to respond, and may default into a determination against them when they had valid documentation.

Missed Credits: The Unrealized Financial Relief

The Earned Income Tax Credit (EITC) is the federal government's largest income support program for working families — providing up to $7,430 (in 2023) to qualifying low-income workers with children. It is also one of the credits most systematically underutilized by LEP families. Research on EITC participation rates has consistently found that eligible LEP households claim the credit at lower rates than eligible English-speaking households, even when income levels, family structure, and other eligibility factors are comparable.

The mechanisms are multiple. LEP filers may use paid preparers who don't ask the right questions. They may use basic tax software that requires navigating English-language prompts about specific eligibility criteria. They may not know the credit exists. The EITC's complexity — particularly for self-employed filers who must calculate net self-employment income, which is common in cash-economy industries where many LEP workers are employed — creates additional barriers for filers with limited financial literacy in English.

Other commonly missed credits for LEP families include the Child Tax Credit (up to $2,000 per qualifying child), the Child and Dependent Care Credit (for childcare expenses), the American Opportunity Credit and Lifetime Learning Credit for education expenses, and state-level equivalents of the EITC that many states have enacted. For a family missing several of these credits, the total refund gap can be several thousand dollars annually — a substantial amount for households with modest incomes.

Unscrupulous Preparers: The Language Gap as Exploitation Vector

LEP filers who cannot independently use tax software and who cannot access free filing assistance rely on paid preparers. The paid tax preparation industry is partly regulated — enrolled agents, CPAs, and attorneys must meet professional standards — but a large portion of preparers are unenrolled, meaning they face minimal regulatory requirements. In immigrant communities, informal tax preparers ("notarios" in some Spanish-speaking communities, informal practitioners in many other language communities) may offer tax preparation services without the credentials, knowledge, or ethical obligations of regulated preparers.

These practitioners may file incorrect returns that miss credits the filer is entitled to while charging fees for the service. They may claim improper deductions that create audit risk. They may retain control of the filer's refund check and charge additional fees. Some have been documented filing returns claiming refundable credits the filer was not entitled to, generating refunds that were paid to the preparer or refund anticipation loan arrangements that extracted fees from filers who didn't understand the terms.

LEP filers are disproportionately vulnerable because they cannot independently verify whether their return is accurate, cannot easily shop for alternative preparers (who may not speak their language), and may not know they can report preparer misconduct or seek redress. The IRS's VITA (Volunteer Income Tax Assistance) program specifically addresses this gap — providing free, quality-reviewed tax preparation to low-income filers — but capacity is limited and language coverage varies substantially outside of Spanish.

Mixed-Status Households: The Most Complex Tax Scenarios

A substantial number of families are "mixed-status" — some members have Social Security numbers, others have ITINs, and in some cases some members have no tax identification at all. These households face particularly complex filing scenarios: whether to file jointly or separately, how to report income for each taxpayer, how to claim dependents who may have ITINs rather than SSNs, and how to navigate credits that have different rules depending on the identification numbers involved.

The EITC, for example, has specific rules about the Social Security numbers of qualifying children. Families where some children have SSNs and others have ITINs may face different eligibility calculations for each child. Getting this right requires understanding IRS rules that are technical and nuanced even in English. Getting it wrong can result in disqualification from the credit or an audit — either of which imposes costs on families for whom the tax return may represent a significant portion of annual income.

VITA and Free Filing: Partial Solutions

The IRS's Volunteer Income Tax Assistance program partners with community organizations to provide free tax preparation for filers with incomes below approximately $67,000. VITA sites are specifically required to serve LEP individuals and are staffed by trained volunteers. Many VITA sites have Spanish-speaking volunteers; larger sites in high-LEP communities may have volunteers for Vietnamese, Chinese, or other languages. In some communities, VITA sites have become the primary trusted mechanism for LEP filer access to quality tax preparation.

VITA's limitations are capacity and coverage. The program operates primarily during tax season (February to April) and is not available for year-round tax questions, amended returns, or correspondence with the IRS. Geographic coverage is uneven — urban areas with community organizations have more sites; rural areas and smaller cities have fewer. Language coverage outside of Spanish is inconsistent and depends entirely on the volunteers available at a specific site in a specific year.

For the full population of LEP filers — millions of individuals whose tax situations range from straightforward to genuinely complex — VITA represents a partial solution. It reaches many of the most vulnerable filers and provides high-quality service where available. It cannot, given its volunteer-based capacity, reach everyone who needs it. And it does not address the language barriers in IRS correspondence and notices that affect LEP filers throughout the year, not just during filing season.
