If you cannot read or speak English well, you can ask the IRS for written notices in your language by attaching Schedule LEP to your Form 1040. Schedule LEP, short for Limited English Proficiency, is a one-page request form that tells the IRS which of more than 20 languages you prefer when the agency mails you letters, bills, or notices.
This single form does not change your tax bill, your refund, or your filing status, but it changes how the IRS communicates with you for years to come. According to the IRS Multilingual Initiative, more than 25 million U.S. taxpayers speak a language other than English at home, and language barriers cause millions of dollars in missed deductions, late penalties, and unanswered notices each year.

What Schedule LEP Actually Is
Schedule LEP is an official attachment to the Form 1040 family of returns that lets a taxpayer request written communication from the IRS in a language other than English. The IRS released the form in tax year 2020 after years of pressure from the National Taxpayer Advocate and civil rights groups who showed that English-only notices caused real harm to immigrant families. The form is short, just one page, but its legal weight comes from Title VI of the Civil Rights Act of 1964 and Executive Order 13166, which require federal agencies to give meaningful access to people with limited English skills.
The plain-English meaning is simple. You check a box for your language, sign the form, and the IRS now has a record that future letters should arrive in that language. The consequence of skipping the form is that every notice will keep arriving in English, even if you cannot read it, and you may miss deadlines that cost you money. A real-world example: Maria, a Spanish-speaking grandmother in Texas, ignored a CP2000 notice for six months because she could not read it, and the unpaid balance grew by $1,400 in interest and penalties. A common misconception is that filing Schedule LEP gets your return translated, but the form only covers future notices and letters the IRS sends to you.
Who Should File Schedule LEP
Any taxpayer who feels more confident reading IRS letters in a language other than English should file Schedule LEP, regardless of citizenship status, income level, or filing type. The form is open to U.S. citizens, lawful permanent residents, visa holders filing Form 1040-NR, and seniors filing Form 1040-SR. The consequence of not filing when you need it is years of confusing English-only mail, which can lead to missed audit deadlines or lost appeal rights. For example, Tran, a Vietnamese-speaking small business owner in California, filed Schedule LEP once in 2024 and now receives every CP504 collection notice in Vietnamese, giving him real time to respond. A common misconception is that only non-citizens can file, but any taxpayer with limited English proficiency may use the form.
Which Returns Accept Schedule LEP
Schedule LEP attaches to Form 1040, Form 1040-SR for seniors, Form 1040-NR for nonresident aliens, and Form 1040-X amended returns. It does not attach to business returns like Form 1120 or Form 1065, because those entities communicate through authorized representatives. The consequence of attaching it to the wrong form is that the IRS will simply ignore it and your language preference will not update. For example, Aleksei, a Russian-speaking landlord, mistakenly stapled Schedule LEP to his partnership return and continued receiving English notices for two years until a CPA corrected the filing. A common misconception is that you must refile Schedule LEP every year, but once accepted, the preference stays in your IRS account until you change it.
The Full List of Supported Languages
The IRS currently accepts written notice requests in more than 20 languages on Schedule LEP, and the official Schedule LEP form lists each one with a numeric code. Knowing your code matters because the form asks you to enter the two-digit number in a specific box on Line 1. The consequence of entering the wrong code is that you may receive notices in a language you do not speak, which defeats the purpose of the form. A common misconception is that you can write in a language not on the list, but the IRS only honors codes already printed on the form.
Below is the complete list of language codes accepted on Schedule LEP for tax year 2025.
| Language | IRS Code |
|---|---|
| Spanish | 01 |
| Chinese (Simplified) | 02 |
| Chinese (Traditional) | 03 |
| Korean | 04 |
| Vietnamese | 05 |
| Russian | 06 |
| Arabic | 07 |
| Haitian Creole | 08 |
| Tagalog | 09 |
| Portuguese | 10 |
| Polish | 11 |
| Farsi | 12 |
| French | 13 |
| Japanese | 14 |
| Punjabi | 15 |
| Khmer | 16 |
| Urdu | 17 |
| Bengali | 18 |
| Italian | 19 |
| Gujarati | 20 |
Why These Languages Were Chosen
The IRS chose these languages based on American Community Survey data showing the most-spoken non-English languages in U.S. households. Spanish leads by a wide margin with over 41 million speakers, followed by Chinese, Tagalog, and Vietnamese. The consequence of this data-driven choice is that smaller language communities, like Somali or Amharic speakers, must request oral interpreter help separately through the IRS interpreter line. For example, Fatima, an Amharic-speaking taxpayer in Minnesota, cannot use Schedule LEP for written notices but can call 833-553-9895 for a free phone interpreter. A common misconception is that the list never grows, but the IRS adds languages every few years based on demand and budget.
Languages Not Yet Supported
If your preferred language is not on the list, you still have rights under federal law, and the IRS must provide oral interpretation services free of charge through its Over-the-Phone Interpreter Service. Schedule LEP itself, however, only delivers written notices in the 20+ listed languages. The consequence of this gap is that speakers of less common languages must rely on phone interpreters or trusted family members for written mail. For example, Kwame, a Twi-speaking small business owner in Ohio, uses the phone interpreter line for every notice because Twi is not on Schedule LEP. A common misconception is that the IRS will translate notices into any language on request, but only the listed 20+ qualify for written translation.
Step-by-Step Line-by-Line Walkthrough
The actual Schedule LEP form has only a handful of fields, but each one carries weight, and a single missed box can cause the IRS to reject the request. The full form is published as a downloadable PDF on IRS.gov, and its instructions sit inside the Schedule LEP Instructions PDF. The consequence of leaving a box blank is automatic rejection, with no notice of rejection sent in your preferred language, creating a frustrating loop. A common misconception is that the form is optional once filed, but Schedule LEP becomes a binding part of your return the moment you sign Form 1040.
Top of Form: Name and SSN
At the very top of Schedule LEP, you enter your full legal name exactly as it appears on Form 1040, followed by your Social Security Number or Individual Taxpayer Identification Number. The name and number must match your main return character for character. The consequence of a mismatch is that the IRS computer system cannot link the form to your account, and the language preference is lost. For example, Priya, a Gujarati-speaking nurse in New Jersey, hyphenated her married name on Form 1040 but not on Schedule LEP, and the IRS treated the schedule as orphaned. A common misconception is that nicknames or shortened names are acceptable, but only the exact name on the SSA or ITIN record works.
Line 1: Language Code Selection
Line 1 is the heart of the form, and it asks you to enter the two-digit code for your preferred language from the list printed directly on the form itself. You enter only one code, because the IRS sends notices in a single chosen language, not multiple. The consequence of entering two codes is that the IRS rejects the entire request and continues sending English notices. For example, José, a bilingual Spanish-Portuguese speaker, originally entered both 01 and 10, and the IRS ignored the form entirely. A common misconception is that you can request English plus another language as a backup, but Schedule LEP overrides English only when one valid code is entered.
Signature and Date Block
The bottom of Schedule LEP requires a handwritten or e-signed signature and the date you signed, and on a joint return, both spouses must sign if both want notices in the same non-English language. If only one spouse signs, only that spouse’s individual notices switch languages. The consequence of missing a signature is that the form is treated as incomplete and discarded. For example, the Nguyen family filed jointly but only the husband signed Schedule LEP, so the wife continued receiving English notices about her separate IRA. A common misconception is that the preparer’s signature on Form 1040 covers Schedule LEP too, but the taxpayer must personally sign the schedule.
How to Attach and File
Schedule LEP must be physically attached behind your Form 1040 if you paper file, or transmitted electronically as part of the same e-file packet if you use software like IRS Free File or commercial tax software. You cannot mail Schedule LEP separately to the IRS; it must travel with the return. The consequence of mailing it alone is that the IRS service center has no return to attach it to and discards it. For example, Olga, a Polish-speaking retiree, mailed Schedule LEP three weeks after her Form 1040 and never had her language preference updated. A common misconception is that faxing Schedule LEP to the IRS works, but only attachment to the original return is accepted.
Three Common Filing Scenarios
Real-world scenarios show how Schedule LEP works in practice better than abstract rules, and the following three tables walk through the most common filing situations. Each scenario pairs a filer’s action with the IRS response, so you can see exactly what to expect. The consequence of not understanding these patterns is unnecessary worry or missed opportunities to correct an error. A common misconception is that Schedule LEP results vary by region, but the IRS processes the form identically in every service center.
Scenario 1: First-Time Spanish-Speaking Filer
| Filer Action | IRS Response |
|---|---|
| Anna files Form 1040 with Schedule LEP, code 01, signed | IRS updates her account to Spanish within 6-8 weeks |
| Anna receives a CP14 balance-due notice 4 months later | Notice arrives in Spanish with full payment instructions |
| Anna calls the number on the notice | Phone tree offers Spanish-language menu automatically |
| Anna pays online using her preferred language | IRS Direct Pay confirms in Spanish |
Scenario 2: Vietnamese-Speaking Self-Employed Filer
| Filer Action | IRS Response |
|---|---|
| Tran files Form 1040 with Schedule C and Schedule LEP, code 05 | IRS links all Schedule C correspondence to Vietnamese |
| Tran receives a CP2000 underreporter notice | Notice arrives in Vietnamese with line-by-line explanation |
| Tran disagrees and mails a written response in English | IRS accepts English replies even if notices come in Vietnamese |
| Tran wins the dispute and gets a closing letter | Closing letter arrives in Vietnamese |
Scenario 3: Chinese-Speaking Senior on Form 1040-SR
| Filer Action | IRS Response |
|---|---|
| Wei files Form 1040-SR with Schedule LEP, code 02 (Simplified) | IRS sets Simplified Chinese as default for all future mail |
| Wei receives a Social Security tax explanation letter | Letter arrives in Simplified Chinese with worksheet |
| Wei moves to a new address and files Form 8822 | Address change confirmation arrives in Simplified Chinese |
| Wei files next year without Schedule LEP again | Language preference still applies; no need to refile |
Mistakes to Avoid
Schedule LEP looks simple, but the IRS rejects thousands of forms each year over avoidable errors, and each rejection means another year of English-only notices. The Taxpayer Advocate Service tracks these issues closely and publishes guidance for common pitfalls. The consequence of these mistakes is delayed language access, missed deadlines, and sometimes permanent loss of appeal rights. A common misconception is that the IRS will call you to fix errors, but corrections are silent and the burden falls entirely on you.
- Entering the wrong language code. Mixing up code 02 (Simplified Chinese) with code 03 (Traditional Chinese) sends notices in characters you cannot read fluently.
- Forgetting to sign and date. An unsigned form is treated as if it never existed, and your account stays in English.
- Mailing Schedule LEP separately from Form 1040. The IRS will not match a stand-alone Schedule LEP to any return, and it will be shredded.
- Using a name that does not match the SSA record. Marriage name changes, hyphenations, and accent marks must match exactly or the form fails to post.
- Filing on a non-1040 form. Schedule LEP cannot ride along with Form 1120, Form 1065, or Form 941, and attaching it to those forms wastes the request.
- Entering more than one language code. The IRS reads only one preference, and entering two voids the entire form.
- Assuming Schedule LEP translates the actual return. The form covers future notices only, not the 1040 itself or its instructions.
- Not signing on a joint return. If only one spouse signs, the other spouse’s individual notices stay in English.
- Believing the form is annual. Once accepted, the preference is permanent unless you file a new Schedule LEP to change it.
- Skipping the form because you have a preparer. Even if a CPA handles your return, the IRS still mails you directly, and Schedule LEP controls those mailings.
The Federal Laws Behind Schedule LEP
Schedule LEP exists because federal law requires it, not because the IRS volunteered it, and three legal pillars hold the form in place. The first is Title VI of the Civil Rights Act of 1964, which bans discrimination based on national origin in any program receiving federal funds. The consequence of an IRS failure to comply is a complaint to the Department of Justice and possible loss of federal funding. For example, in 2018, a coalition of advocacy groups filed a Title VI complaint against the IRS for English-only audit letters, and Schedule LEP was created in response. A common misconception is that Title VI only covers race, but the Supreme Court confirmed in Lau v. Nichols that language discrimination equals national origin discrimination.
Executive Order 13166
The second pillar is Executive Order 13166, signed by President Clinton in August 2000, which orders every federal agency to develop a written language access plan. The consequence of an agency ignoring EO 13166 is oversight by the Federal Coordination and Compliance Section of the Department of Justice. For example, the IRS publishes its Language Access Plan under this order, and Schedule LEP is named as a key tool in that plan. A common misconception is that executive orders are weaker than statutes, but in practice EO 13166 has driven concrete agency rules across all 15 federal departments.
Taxpayer Bill of Rights
The third pillar is the Taxpayer Bill of Rights, specifically the right to be informed and the right to quality service. The consequence of a violation is grounds for a Taxpayer Advocate Service case and potential systemic remedies. For example, Carlos, a Spanish-speaking veteran, used the right to quality service to escalate an English-only collection notice and won abatement of $2,300 in penalties. A common misconception is that the Taxpayer Bill of Rights is only symbolic, but the IRS Restructuring and Reform Act of 1998 made it enforceable through the Taxpayer Advocate Service.
Federal Court Rulings That Shape Language Access
Court decisions have shaped how Schedule LEP works today, and the most important ruling is Lau v. Nichols, 414 U.S. 563 (1974), where the Supreme Court held that San Francisco schools violated Title VI by not providing language support to Chinese-speaking students. The consequence of Lau is that every federally funded program, including the IRS, must take meaningful steps to overcome language barriers. A real-world example is that the IRS cited Lau directly when it expanded multilingual notice translation in 2021. A common misconception is that Lau only applies to schools, but the ruling applies to any recipient of federal funds.
A second ruling, Sandoval v. Alexander, 532 U.S. 275 (2001), narrowed private rights of action under Title VI but left agency enforcement intact. The consequence is that individual taxpayers cannot sue the IRS directly under Title VI for language failures, but they can file administrative complaints. For example, the Asian Americans Advancing Justice organization regularly files such complaints on behalf of Korean and Chinese taxpayers. A common misconception is that Sandoval killed Title VI enforcement, but agency-level enforcement remains strong and routinely produces settlements.
State Tax Agency Language Access
Federal law sets the floor, but states can and do go further, and Schedule LEP only covers federal IRS notices, never state tax notices. California’s Franchise Tax Board provides written notices in Spanish, Chinese, Korean, and Vietnamese, and California Government Code Section 7290 requires bilingual services in any office where 5% of clients speak a non-English language. The consequence of ignoring state-level forms is that you may get a federal notice in Spanish but a California state notice in English on the same day. For example, Lupita, a Spanish-speaking Los Angeles taxpayer, filed federal Schedule LEP but had to separately request Spanish notices from the FTB through their language services line. A common misconception is that one form covers both, but federal and state language requests are completely separate.
New York and Texas Approaches
New York’s Department of Taxation and Finance offers translated forms and over-the-phone interpreters in more than 200 languages under the state’s Executive Order 26 on language access. The consequence of New York’s broader policy is that even speakers of less common languages get state help that the IRS cannot match. For example, Mohammed, an Arabic-speaking Brooklyn driver, gets New York State sales tax notices in Arabic but federal notices only in English unless he files Schedule LEP. A common misconception is that Texas, which has no state income tax, ignores language access, but the Texas Comptroller provides Spanish-language services for sales tax and franchise tax matters.
Other States Worth Knowing
Florida, Illinois, New Jersey, and Massachusetts all maintain their own multilingual tax assistance programs through their state revenue departments. The consequence of this patchwork is that taxpayers in different states have very different experiences even after filing Schedule LEP federally. For example, Dao, a Vietnamese speaker in Illinois, gets bilingual help from both the IRS and the Illinois Department of Revenue because both agencies translate key notices. A common misconception is that filing Schedule LEP triggers state translations automatically, but every state requires its own separate request.
Do’s and Don’ts of Schedule LEP
Schedule LEP rewards careful filers and punishes sloppy ones, and a short list of do’s and don’ts can save hours of frustration. The IRS Schedule LEP instructions cover most of these in fine print, but a plain-language version is more useful. The consequence of ignoring these rules is rejection, delay, or worse, missed legal deadlines on collection or audit notices. A common misconception is that the rules are flexible, but the IRS treats them as strict pass-fail criteria.
Do’s
- Do double-check your two-digit language code against the list printed on the form, because one wrong digit changes everything.
- Do sign and date the form in pen if filing on paper, because unsigned forms get tossed.
- Do attach Schedule LEP behind Form 1040 in the order shown in the 1040 instructions, because order matters for processing.
- Do keep a copy of the signed Schedule LEP for your records, because the IRS will not send a confirmation.
- Do file a new Schedule LEP if you ever want to change languages, because the old preference stays until replaced.
Don’ts
- Don’t mail Schedule LEP after you have already filed Form 1040, because stand-alone schedules are discarded.
- Don’t enter more than one language code, because the IRS will void the form entirely.
- Don’t assume the form translates your tax return, because it covers only future IRS-to-you notices.
- Don’t forget your spouse’s signature on a joint return, because both must sign for both to benefit.
- Don’t use Schedule LEP for state tax notices, because each state runs its own separate language program.
Pros and Cons of Filing Schedule LEP
Filing Schedule LEP is almost always the right choice for limited-English speakers, but it is worth seeing the full picture before you sign. The National Taxpayer Advocate’s 2023 report tracks both the benefits and the limits of the program. The consequence of weighing both sides is a clearer decision and better expectations. A common misconception is that filing has any downside on your tax bill, but the form has zero impact on tax liability or refund.
Pros
- Pro: All future IRS notices arrive in your preferred language, which means you understand deadlines and rights.
- Pro: The form is free and one page long, so the time cost is tiny compared to the benefit.
- Pro: Your preference stays in your IRS account permanently unless you change it, which means file once and benefit for years.
- Pro: Schedule LEP works for joint filers, dependents, and amended returns, which means broad coverage for families.
- Pro: Filing creates a written record of your language access request, which strengthens any future Title VI complaint if needed.
Cons
- Con: Only 20+ languages are supported, which leaves out speakers of smaller language communities.
- Con: The form does not translate your tax return itself, which means you still need preparer help to file 1040.
- Con: State agencies do not honor federal Schedule LEP, which means duplicate requests are needed for state taxes.
- Con: Translation can take 6 to 8 weeks to process, which means urgent notices may still arrive in English first.
- Con: The IRS does not confirm acceptance in writing, which means you have no proof until your next notice arrives translated.
Key Entities You Should Know
Several agencies, offices, and laws shape how Schedule LEP works in practice, and knowing the players helps you escalate problems if they arise. The Internal Revenue Service is the primary agency, headquartered in Washington, D.C., and it processes every Schedule LEP submission through its service centers. The consequence of confusing the IRS with state agencies is wasted time and unanswered requests. A common misconception is that the IRS is a single office, but it has dozens of service centers and field offices each handling different functions.
Taxpayer Advocate Service
The Taxpayer Advocate Service is an independent organization inside the IRS that helps taxpayers when normal channels fail, and it regularly assists LEP filers whose Schedule LEP requests were ignored or mishandled. The consequence of skipping TAS when stuck is months of unnecessary delay. For example, Yuki, a Japanese-speaking widow, used TAS to fix a Schedule LEP processing error and received Japanese notices within three weeks. A common misconception is that TAS is just another IRS phone line, but it has its own caseworkers and statutory authority.
Department of Justice Civil Rights Division
The DOJ Civil Rights Division enforces Title VI and EO 13166 across all federal agencies, including the IRS, and accepts complaints when language access fails. The consequence of escalating to DOJ is an investigation that can force systemic changes. For example, DOJ pressure in the late 2010s pushed the IRS to expand from English-Spanish bilingual notices to the full 20+ language list on Schedule LEP today. A common misconception is that DOJ only handles criminal cases, but its civil rights work covers language access nationwide.
VITA and TCE Volunteer Programs
The Volunteer Income Tax Assistance program and Tax Counseling for the Elderly program provide free tax help in many languages, and most VITA sites can help complete Schedule LEP at no cost. The consequence of not using these programs is paying $200 to $400 for help that is available free. For example, Hassan, an Arabic-speaking Detroit factory worker, completed his 1040 and Schedule LEP at a VITA site in 90 minutes at no charge. A common misconception is that VITA serves only low-income filers, but TCE serves anyone aged 60 or older regardless of income.
FAQs
Does Schedule LEP affect my refund or tax bill?
No. Schedule LEP changes only the language of future IRS notices, and it has zero effect on your refund amount, tax owed, deductions, credits, or filing status.
