What a background check report may include

Who it covers: Anyone reporting criminal history records, in practice consumer reporting agencies (610.143); all employers (inquiry rules in 610.140.11 and 610.141).

In force since: August 28, 2026

No state 7-year rule. Since August 28, 2026 (SB 1421), records of arrests, indictments pending trial, and convictions may no longer be reported once it is learned that a full pardon or expungement was granted, or that an arrest or indictment did not end in a conviction (RSMo 610.143.1). The attorney general may sue for an injunction and damages, and an affected consumer may get an injunction. On inquiries: a person whose record was expunged by petition may answer ‘no’ to an employer’s question about arrests, charges, or convictions if no public record remains (610.140.11). For offenses expunged automatically under 610.141, no inquiry may be made about the expungement at all, and the person need not disclose it (610.141.1(7)). Exceptions: the person must disclose an expunged offense when applying to a federally insured bank or credit union, an insurer subject to 18 U.S.C. 1033, or an entity allowed to see closed records under 610.120 (610.143.5), or when law requires the employer to exclude people with certain convictions (610.140.11).

Exceptions

  • 610.140.11 and 610.143.5: disclosure still required for federally insured banks and credit unions, insurers under 18 U.S.C. 1033-1034, entities with access to closed records under 610.120, and positions where law requires excluding certain convictions

RSMo 610.140.11 (version effective January 1, 2025) · RSMo chapter 407 section list (Merchandising Practices) · RSMo 610.143.1 (L. 2026 SB 1421; effective August 28, 2026) · RSMo 610.141.1(7) (L. 2026 SB 1421), truly agreed bill text · RSMo 610.143.5 (L. 2026 SB 1421)

Sealed and expunged records

Who it covers: All employers.

In force since: August 28, 2026

Two tracks. (1) Petition: a person may petition 3 years after completing a felony sentence or 1 year after a misdemeanor, with lifetime limits of 2 felonies and 3 misdemeanors (610.140). (2) Automatic: SB 1421 (signed July 9, 2026) adds petition-free expungement by the Highway Patrol’s central repository, screened at least weekly, for drug possession and paraphernalia convictions only (195.202 and 195.233 as they existed before 2017; 579.015; 579.074). An offense qualifies if it is the only conviction in the case, 1 year (misdemeanor) or 3 years (felony) have passed since final disposition with no new conviction in that time, no charges are pending, and it is not a class A felony. It applies retroactively to electronic records. The section took effect August 28, 2026 but runs ‘when technically feasible’, and no later than January 1, 2027. The automatic and petition tracks share the 3-misdemeanor and 2-felony lifetime cap. Marijuana offenses were expunged automatically under the 2022 constitutional amendment. An employer, volunteer organization, or landlord that engages a person with an expunged record is immune from claims about misconduct related to the expunged record, unless it failed to use reasonable care (610.143.4).

Exceptions

  • 610.140: listed offenses are never eligible (not re-read this pass)
  • Mo. Const. art. XIV sec. 2.10(8): distribution to a minor, violent offenses, and driving under the influence are excluded from automatic marijuana expungement

XIV sec. 2.10(8)(a) · RSMo 610.141.1(6) (qualifying offenses), truly agreed SB 1421 · RSMo 610.141.1(3)(d) · RSMo 610.141.10 (operative date) · RSMo 610.141.10, truly agreed SB 1421 · RSMo 610.143.4 (employer immunity) · SB 1421 (2026) action history

Cannabis use and testing

Who it covers: All employers.

In force since: December 8, 2022

Medical cardholders are protected; adult-use consumers are not. Under the constitution, an employer may not discriminate in hiring, firing, or any term of employment against a qualifying patient or caregiver with a valid card, including for legal off-premises use during nonworking hours, or because of a positive marijuana test, unless the person used, possessed, or was under the influence at work or during work hours, unless the employer would lose a federal monetary or licensing benefit, or unless the position is one where cannabis use affects job duties or safety or conflicts with a bona fide occupational qualification. For adult use, the constitution requires no accommodation and lets employers discipline or take adverse action for working while under the influence; it gives no off-duty protection and no testing limit. Missouri’s off-duty statute (290.145) covers alcohol and tobacco only.

Exceptions

  • Art. XIV sec. 1.7(15): use or impairment on the premises or during work hours; loss of a federal monetary or licensing benefit; positions where use affects duties or safety or conflicts with a bona fide occupational qualification
  • Art. XIV sec. 2.3(3): no duty to permit or accommodate adult use; discipline for working while under the influence

Mo. Const. art. XIV sec. 1.7(15) · Mo. Const. art. XIV sec. 1.7(15)(a) · Mo. Const. art. XIV sec. 1.7(15)(b) · Mo. Const. art. XIV sec. 2.3(3) · Mo. Const. art. XIV sec. 2 (revisor effective-date line)

The state consumer reporting law

Who it covers: N/a

No state consumer reporting act. Missouri has no extra disclosure or authorization form, no investigative-report rule, and no CRA registration. Two 2026 changes touch CRAs: RSMo 610.143 bars reporting pardoned, expunged, or non-conviction records (see reporting_limits), and 610.141.11 lets a CRA get data from the Highway Patrol to delete automatically expunged records, if it signs a use-and-destroy agreement. The Highway Patrol’s fee for a name-based state record check may now reach $20 (43.530.1).

RSMo chapter 407 section list · RSMo 610.141.11 (L. 2026 SB 1421) · RSMo 43.530.1 (as amended by SB 1421; effective August 28, 2026)

Where federal law alone applies

We found no Missouri rule for private employers on these topics. The FCRA and other federal laws still apply.

  • Criminal history questions
  • Credit checks
  • Salary history
  • Drug testing procedures

Local rules

Some places in Missouri add their own rules. A local rule applies on top of the state rule.

Coming changes

Laws already passed that take effect later.

  • From January 1, 2027. SB 1421 (2026) automatic expungement (RSMo 610.141): the statute took effect August 28, 2026, but the weekly automated expungement runs only ‘when technically feasible’, and no later than January 1, 2027. Covers drug possession and paraphernalia convictions only. CCS SS SB 1421 (2026), RSMo 610.141.10; signed July 9, 2026

Every state’s changes, in date order: What changed.

Adverse action notices

Before you reject or act against someone because of a background check report, the FCRA requires a pre-adverse action notice, a wait, and then a final notice. The adverse action letter generator writes both notices and adds the Missouri requirements where they apply.

The waiting period calculator gives the date under the federal rule.

Paperwork at hire

Besides the federal Form I-9 and W-4, Missouri sets these for each new hire.

  • State withholding. Have each new hire complete Form MO W-4; if the employee does not turn one in, withhold at the single rate. Form MO W-4
  • New hire report. Report each new hire to Missouri within 20 days. State new hire reporting
  • Notices at hire. Missouri adds none beyond the federal forms that every employer gives.

Build the new hire checklist for Missouri, with city rules, special cases and a due date for each item.

After the hire

Once a background check clears, payroll and onboarding come next. Rippling (paid link) runs payroll, benefits and onboarding from one employee record.
