Understanding Schedule LEP (Form 1040): Request for Change in Language Preference

1. Introduction – What is Schedule LEP (Form 1040)?

Schedule LEP (Form 1040), officially titled “Request for Change in Language Preference,” is an optional federal tax schedule administered by the Internal Revenue Service (IRS), an agency of the U.S. Department of the Treasury.

It is attached to Form 1040, Form 1040-SR, or Form 1040-NR by individual taxpayers with Limited English Proficiency (LEP). Schedule LEP allows non-native English speakers and multilingual taxpayers to officially request that future written IRS communications, tax notices, and compliance letters be sent to them in their preferred primary language.

2. Purpose of the Form – Why Does Schedule LEP Exist?

Understanding federal tax notices, audit inquiries, or balance due letters can be challenging, especially for taxpayers who are not fully fluent in written English. Receiving complex legal tax notices in English can lead to confusion, missed response deadlines, and unnecessary tax penalties.

Schedule LEP exists to promote language access and taxpayer rights across the federal tax system. By filing Schedule LEP, taxpayers can select from more than 20 non-English languages.

The IRS records this language preference in the taxpayer’s permanent master file. Whenever translated versions are available, the IRS will automatically issue future written communications—such as tax refund notifications, balance statements, or information requests—in the taxpayer’s requested language.

3. Who Needs to File This Form

Schedule LEP (Form 1040) is an optional, voluntary form designed for individual taxpayers. You should complete and attach Schedule LEP if you meet these criteria:

• Limited English Proficiency Taxpayers: Individuals who prefer reading official IRS correspondence in a language other than English.
• Nonresident Aliens & Immigrants: Foreign nationals filing Form 1040-NR or recent immigrants filing Form 1040 who prefer written tax letters in their native language.
• Senior Citizens (Form 1040-SR): Older adults who feel more comfortable reviewing tax notices in their primary language.
• Taxpayers Updating Language Preferences: Individuals who previously selected a language with the IRS and want to update or change their written communication preference.

4. Who Is Exempt / Not Required to File

You do not need to fill out or attach Schedule LEP (Form 1040) if your situation falls into any of these categories:

• English-Fluent Taxpayers: Individuals who are comfortable receiving all IRS notices, letters, and tax statements in English.
• Existing Preference Unchanged: Taxpayers who already registered their preferred language with the IRS in a prior tax year and do not wish to change it.
• Corporate & Entity Filers: Businesses, corporations, partnerships, or non-profits filing commercial returns (Schedule LEP is strictly for individual tax returns).

5. When to File

Schedule LEP is an annual schedule attached directly behind Form 1040, Form 1040-SR, or Form 1040-NR, so it follows the exact filing deadline of your primary return.

The standard federal filing deadline is **April 15** following the close of the calendar tax year (or **October 15** if a valid 6-month extension is requested on Form 4868). You can attach Schedule LEP in any tax year when submitting your annual tax return.

6. Where and How to File

Schedule LEP cannot be submitted as a standalone document. It must be attached directly behind Form 1040, Form 1040-SR, or Form 1040-NR.

Taxpayers can e-file Schedule LEP alongside Form 1040 using IRS Direct Pay, IRS Free File, or commercial tax preparation software. If paper filing, attach Schedule LEP directly behind Form 1040 and mail the complete filing package to the specific IRS service center address as per instructions for Form 1040 based on your residency and payment status.

Detailed Filling Steps

1. Complete Taxpayer Identification Header: Enter your full legal name and Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) at the top of the schedule. If filing a joint return, enter your spouse’s name and SSN/ITIN as shown on Form 1040.
2. Select One Preferred Language: Review the list of 20+ supported languages. Check **only one box** corresponding to your preferred primary written language.
3. Attach directly Behind Form 1040: Place Schedule LEP directly behind Form 1040 or Form 1040-SR when compiling your tax return package for e-filing or paper mailing.

8. Required Documents/Information Needed Before Filling

Completing Schedule LEP requires minimal paperwork. Gather the following information before filling out the form:

• Taxpayer Identification Numbers: SSN or ITIN for yourself (and your spouse if filing jointly).
• Primary Income Tax Return: Form 1040, Form 1040-SR, or Form 1040-NR.
• Language Selection: Knowledge of which written non-English language you want the IRS to use for future notices.

9. Common Mistakes to Avoid

While Schedule LEP is straightforward, minor errors can delay your language preference update. Watch out for these frequent mistakes:

• Checking Multiple Language Boxes: Selecting more than one language box on the form. You must select only *one* primary language.
• Submitting as a Standalone Form: Attempting to mail Schedule LEP by itself to the IRS. Schedule LEP must always be attached to Form 1040.
• Expecting All Tax Software to Print in Foreign Languages: Believing that filing Schedule LEP will cause your tax preparation software to display or print Form 1040 in another language. Your annual Form 1040 tax return is still prepared in English, but future *IRS written notices* sent after return processing will arrive in your chosen language.
• Expecting Phone Translation Changes Automatically: Believing Schedule LEP alters IRS telephone customer service languages. Live phone interpretation is requested verbally whenever you call the IRS customer service helpline.

10. Penalties for Non-Filing or Errors

Schedule LEP is a voluntary taxpayer preference form. There are **zero financial penalties, fines, or interest** for failing to file Schedule LEP, omitting it, or making an error on the form.

However, selecting the wrong language box could cause future IRS letters to arrive in a language you cannot read, potentially causing you to misinterpret important tax deadlines or notices.
