E-Verify Requirements in Missouri: Employer Obligations

Under the Immigration Reform and Control Act (IRCA), 8 U.S.C. section 1324a, all employers—regardless of size—must verify that employees are authorized to work in the United States using Form I-9. However, E-Verify (the electronic system) is only mandatory for federal contractors and subcontractors under 41 U.S.C. section 4712 and FAR clause 52.204-12. Federal contractors must verify all new hires within 3 business days of employment start date.

E-Verify is a free online system operated by USCIS and DHS that compares information from employee Form I-9 documents against Social Security Administration and Department of Homeland Security records. Private employers are not required to use E-Verify but may voluntarily participate. Employers who knowingly hire unauthorized aliens face civil penalties ranging from $375 to $16,000 per violation depending on whether it is a first, repeat, or aggravated offense. Criminal penalties also exist for pattern and practice violations. The EEOC enforces Form I-9 compliance for non-federal employers.

Missouri does not impose a statewide E-Verify mandate for private employers, making it less restrictive than some states like Arizona and Mississippi. Missouri Statute section 285.525 applies only to public employers, requiring use of E-Verify for all new employees hired by the state and political subdivisions. This means private employers in Missouri have no state-law obligation to use E-Verify unless they are federal contractors.

Under Missouri law, public employers must use E-Verify and complete verification within 3 business days of employment commencement. However, this requirement does not extend to private sector employers. Missouri's approach aligns with federal policy: only those receiving federal contracts must verify electronically. All Missouri employers, whether public or private, must still complete Form I-9 for all employees and maintain compliance with federal IRCA requirements.

Missouri does not provide state-specific penalties for E-Verify non-compliance for private employers. Instead, federal sanctions apply. The state has not enacted additional protections or remedies for workers or employers beyond federal law. This means a Missouri private employer cannot be sanctioned by the state for failing to use E-Verify, but federal contractors in Missouri face the same federal penalties as contractors nationwide.

Federal contractors are exempt from E-Verify if they hire only workers who present a valid passport or other federally acceptable document that itself proves work authorization without additional verification. However, this exception is narrow and rarely applicable in practice. Employees hired before December 19, 2009, cannot be required retroactively to participate in E-Verify under federal law, even for federal contractors.

Missouri law exempts private employers entirely from E-Verify mandates, meaning a private employer cannot face state sanctions for non-use. However, if a federal contract is involved, the federal requirement supersedes. Employers can rely on I-9 verification using paper documents without E-Verify for private sector hires (though this creates higher liability risk for hiring unauthorized workers). Self-employed individuals and sole proprietors are not covered by IRCA requirements.

Employees have limited defenses if E-Verify generates a mismatch notice. While workers may contest mismatches through SSA or DHS channels, employers are not required to terminate employment solely based on E-Verify findings. However, federal contractors must resolve mismatches within a specified window before any termination. Missouri employers cannot discriminate based on national origin or citizenship status when enforcing E-Verify or I-9 requirements.

Step 1: Document and Audit Compliance. Gather all employee I-9 forms completed in the past 3 years. For federal contractors, compile E-Verify records showing verification dates and mismatch resolutions. Maintain copies of all work authorization documents (passport, permanent resident card, employment authorization document). Create a compliance log noting hire dates and verification method used. Store documents in a secure location separate from personnel files to minimize discrimination risk.

Step 2: Identify Your Employer Status. Determine whether your company is a federal contractor, subcontractor, or recipient of federal funding. Check SAM.gov (System for Award Management) to see if your organization holds federal contracts. Review all contracts signed since 2009 to identify any FAR flow-down clauses requiring E-Verify. Consult your contracts manager or legal counsel to confirm contractor status. If you are not a federal contractor, E-Verify is voluntary in Missouri.

Step 3: Register for E-Verify if Required. Navigate to e-verify.gov and select "Employer" sign-up. Create an employer account using your company's EIN and business information. Designate a company E-Verify administrator and at least one employee as authorized representative. Complete identity verification for your administrator account (typically takes 10-15 minutes). Obtain your E-Verify Client ID once account is activated. Keep your Client ID and login credentials secured and updated.

Step 4: Verify New Hires Within the Timeframe. After an employee completes Form I-9, enter their name, date of birth, SSN, and document information into E-Verify within 3 business days of hire (federal contractors only; private employers are not legally required). E-Verify will return a status of "Employment Authorized," "Tentative Nonconfirmation," or "Nonconfirmation" within seconds to 24 hours. If the result is Employment Authorized, retain the verification record. If Tentative Nonconfirmation is received, notify the employee in writing within 1 business day and allow them 8 Federal business days to contest through SSA or DHS.

Step 5: Resolve Mismatches and Maintain Records. For any Tentative Nonconfirmation, provide the employee with Form I-797 notice of mismatch and inform them they have 8 Federal business days to appeal through the appropriate agency (SSA or DHS). Track all mismatch cases and their resolution status. Do not terminate employment based solely on E-Verify results; the employee must be given opportunity to correct the mismatch through proper channels. Once mismatch is resolved or appeal period expires, update E-Verify status and document the outcome in your compliance file.

Step 6: Consult an Attorney for Violations or Disputes. If you receive an I-9 audit notice from ICE, immediately contact an employment law attorney licensed in Missouri who handles immigration compliance. If an employee contests a mismatch or E-Verify result, do not proceed with termination without legal advice. If an employee claims discrimination based on E-Verify enforcement, consult counsel before taking any adverse action. If you discover you have hired unauthorized workers, consult an attorney before self-reporting (voluntary disclosure may reduce penalties but has strategic implications).
