SSA No-Match Letters: Employer Obligations and Employee Rights

An SSA no-match letter is a notice from the Social Security Administration telling an employer that a name or Social Security number on a W-2 does not match what SSA has on file. It says nothing about a worker’s immigration status or work authorization. Its only purpose is to make sure earnings get credited to the right person’s lifetime record, which later determines retirement, disability, and survivor benefits. What the employer is allowed to do next, and what the employee needs to do to fix the record, are both narrower than most people assume.

What a No-Match Notice Actually Means

A mismatch is a records problem. Most trace back to clerical mistakes: a misspelled surname, a transposed digit, an unreported name change after marriage or divorce, or a data-entry slip in payroll. None of those tell you anything about whether the worker is authorized to be employed in the United States.

This boundary matters because federal regulation says so directly. The rule defining “constructive knowledge” of unauthorized employment makes clear that an employer cannot infer a worker is unauthorized from foreign appearance or accent, and cannot demand more documents than the law requires.¹ A name or SSN mismatch, on its own, does not put an employer on notice that anyone is working without authorization. The Department of Homeland Security once tried to write a rule linking no-match letters to constructive knowledge; litigation blocked it and it never took effect.

How Employers Find Out About Mismatches Now

The paper letters people remember are gone. The SSA suspended its Decentralized Correspondence (DECOR) notices to employees in August 2012 for budget reasons.² It discontinued Employer Correction Request Notices (EDCOR) in April 2021.³ When someone refers to a “no-match letter” today, they usually mean the concept, not something that arrived in the mail.

Employers now see mismatch data through the SSA’s Business Services Online (BSO) portal. Registering for a BSO account, adding the “View Wage Report Name/SSN errors” service, and completing a one-time activation opens up a view of which W-2 submissions contained name or SSN errors.³ Employers can also verify names and SSNs before filing through the Social Security Number Verification Service, restricted to current or former employees and used only for W-2 wage-reporting purposes.⁴

What the Employer Should Do

Start inside the company. Compare the flagged name and SSN against payroll and personnel files. If the mistake is internal, a typo or an outdated record, correct it and resubmit the data following SSA’s instructions.⁵

If internal records match what was submitted, the next step is to tell the employee. Give them enough detail to understand what didn’t match, and give them a reasonable window to sort it out with the SSA. No federal statute pins down how long “reasonable” is. As a practical benchmark, SSA allows up to 120 days to resolve tentative nonconfirmations in E-Verify, on the assumption that database corrections can take that long.⁶

During that window, employment terms stay the same. No reduced hours, no reassignment, no pressure to resign. The employer’s role is to review records and pass information along, not to investigate the worker.

What the Employer Must Not Do

This is where employers create legal exposure. Firing, suspending, demoting, or threatening a worker based only on a mismatch is the kind of reaction that generates discrimination claims. Federal law treats it as an unfair immigration-related employment practice.⁷

Demanding new or extra work-authorization documents is just as risky. Under 8 U.S.C. § 1324b(a)(6), asking for more documents than Form I-9 requires, or rejecting documents that appear genuine on their face, is document abuse when done with discriminatory intent.⁷ If the original I-9 was completed properly, a name or SSN mismatch is not a reason to re-verify eligibility.

Penalties for a first discrimination violation run from $250 to $2,000 per worker, and $3,000 to $10,000 per worker for employers with prior orders. Document abuse carries $100 to $1,000 per affected individual.⁷ Enforcement is handled by the Department of Justice’s Immigrant and Employee Rights Section (IER). Workers must file a charge within 180 days of the discriminatory act; the deadline is strict.⁸ The IER worker hotline is 1-800-255-7688; the separate employer hotline is 1-800-255-8155.⁹

How the Employee Fixes the SSA Record

Correcting the record starts with Form SS-5, the Application for a Social Security Card, which is also used to update information on an existing record.¹⁰ The signed form and supporting documents can be taken or mailed to any SSA office. Documents must be originals, not photocopies or notarized copies.

What to bring depends on the error:¹¹

Name change: a marriage document, divorce decree, certificate of naturalization showing the new name, or a court order approving the change. If the name change was more than two years ago, SSA may also require an identity document in the prior name.
Date of birth correction: a birth certificate, hospital record of birth, valid passport, or religious record established before age five.
Identity verification: a current U.S. driver’s license, state-issued ID card, or U.S. passport. If none are available, SSA will consider an employee ID, school ID, or health insurance card.

At the office, a representative compares the documents against SSA’s electronic records to identify whether the error involves a misspelled name, incorrect date of birth, or transposed SSN digits, and updates the record. Ask for documentation confirming the correction was made; payroll will need proof.

Closing the Loop With Form W-2c

Once SSA updates the record, the employee gives the corrected information to payroll. The employer then files Form W-2c, the Corrected Wage and Tax Statement, along with Form W-3c for each tax year involved. SSA instructs employers to file both “as soon as possible” after discovering the error; there is no specific calendar deadline. The employer must also give the corrected W-2c to the employee, who may need it for tax records if the original error affected reported wages or withholding.¹²

What Happens If the Mismatch Is Never Fixed

Wages reported on a W-2 that SSA cannot match to a record go into the Earnings Suspense File.² Suspended wages are not credited to anyone, so they don’t count toward the work credits needed for retirement, disability, or survivor benefits. The money is not permanently lost; if identifying information is later supplied, the wages can be moved to the correct worker’s record.¹³ Absent a correction, they stay in limbo, and the worker’s future benefit is smaller than the taxes they paid should have earned.

Employers who let mismatches sit face IRS exposure too. For information returns due in 2026, penalties escalate:¹⁴

Filed up to 30 days late: $60 per return
Filed 31 days late through August 1: $130 per return
Filed after August 1 or not filed: $340 per return
Intentional disregard: $680 per return, with no maximum

The intentional-disregard tier is the one that bites in the no-match context. An employer who knows about a mismatch, ignores it, and keeps filing incorrect W-2s can face $680 per form with no cap.¹⁴ The IRS can reduce or waive penalties for reasonable cause and good faith, but that argument gets harder once the employer has been specifically told about the error.
