Pay Frequency Laws in Missouri: How Often Must You Be Paid?

The Fair Labor Standards Act (FLSA), 29 U.S.C. § 201 et seq., does not mandate a specific pay frequency for private sector employers. The federal law enforced by the U.S. Department of Labor requires only that employers pay employees at least the federal minimum wage and overtime compensation when due, but it allows employers to determine their own pay schedules. Some states have established stricter requirements, but federal law leaves pay frequency largely to state regulation. The FLSA applies to employers with at least $500,000 in annual sales or engaged in interstate commerce. Remedies for FLSA violations include back wages, liquidated damages, and attorney's fees through the Department of Labor or private litigation. However, because the FLSA does not regulate pay frequency itself, employees seeking to enforce specific pay schedules must rely on state law protections.

Federal law does require that all wages earned be paid, and some interpretations suggest wages must be paid on a regular schedule, but this is not enforced through a specific frequency mandate. States fill this gap by setting their own pay frequency rules, which often exceed the federal baseline.

Missouri law, codified in Missouri Revised Statutes § 290.110, requires all employers to pay their employees at least twice per month on regular paydays established by the employer. This is a stricter requirement than federal law, which does not mandate any specific pay frequency. Missouri covers all employers, including private employers, regardless of size, with limited exceptions for certain wage categories.

Under Missouri § 290.120, employers must provide employees with at least 7 days' written notice before changing the pay frequency and must obtain written consent from the employee to implement the change. This protects employees from arbitrary or sudden shifts in when they receive their wages. The state law applies to all employees including hourly, salaried non-exempt, and salaried exempt workers, though exempt employees may receive payment on a less frequent schedule in certain circumstances under specific conditions.

Missouri's pay frequency law is significantly stronger than the federal baseline because it establishes a clear, mandatory minimum schedule. Employers cannot require employees to wait longer than a two-week period between paydays. The law also protects workers from unilateral changes by requiring notice and consent, giving employees leverage to object or plan accordingly. Additionally, Missouri prohibits employers from withholding or delaying wages as a disciplinary measure or for any reason other than lawful deductions (such as taxes, garnishments, or authorized deductions).

Exempt employees under the Fair Labor Standards Act may be subject to different rules; however, Missouri still requires regular paydays. The law is enforced through the Missouri Department of Labor and Industrial Relations, which can investigate wage complaints. Remedies include recovery of unpaid wages, penalties, and potential attorney's fees in successful wage claims.

Missouri law provides limited exceptions to the twice-monthly pay frequency requirement. Exempt salaried employees (those meeting the Fair Labor Standards Act definition of exempt) may be paid on a less frequent schedule, though employers must still establish regular paydays and cannot arbitrarily delay payment. Commission-based salespeople may have different arrangements if agreed to in writing, though they must still receive regular pay for non-commission wages at least twice monthly.

Employers may establish different pay frequencies for different groups of employees, provided all receive payment at least twice per month and the arrangement is communicated clearly. Agricultural workers engaged in seasonal work may have different arrangements under certain circumstances, though this exception is narrow. Employers cannot use pay frequency delays as a disciplinary tool or as retaliation for protected conduct such as wage complaints or safety reporting.

The requirement to obtain employee consent before changing pay frequency is a significant protection, meaning employers cannot unilaterally shift employees to monthly or less frequent payment. However, if an employee consents in writing to a different arrangement, courts may enforce that agreement. Federal contractors and employees covered by collective bargaining agreements may have additional or different requirements depending on their contract terms, which can supersede state minimums if more favorable.

Employers in Missouri cannot claim financial hardship as a reason to reduce pay frequency below the twice-monthly requirement. The law is mandatory and not subject to employer discretion based on business circumstances.

Step 1: Document Everything. Keep detailed records of all paychecks you receive, including dates, amounts, and pay stubs. Save copies of your offer letter, employee handbook, and any written communication about pay frequency. If your employer changes pay frequency, document when you learned about the change and whether you provided written consent. Take screenshots of direct deposit confirmations or bank statements showing when payments were deposited. Note any instances where a paycheck was delayed beyond the expected payday and document the reason given, if any. Create a timeline showing the pattern of late or infrequent payments.

Step 2: Internal Complaint and Documentation. Before filing an external complaint, contact your employer's human resources or payroll department in writing (email is acceptable) stating your concern about pay frequency violations. Describe the specific violation: for example, "I have not been paid in over 14 days" or "My pay frequency was changed from twice monthly to monthly without my written consent." Request a written explanation and ask for the violation to be corrected immediately. Keep copies of all correspondence. In some cases, employers will correct the issue once notified; however, if the employer does not respond or refuses to comply within 5-7 business days, proceed to the next step. This creates a paper trail showing good-faith effort to resolve the matter internally.

Step 3: File a Wage Complaint with the Missouri Department of Labor and Industrial Relations. Visit the official Missouri Department of Labor website at labor.mo.gov and locate the Wage and Hour division. You can file a wage complaint online or by mail; phone inquiries can be made at 573-751-2590. Provide detailed information including your name, employer name and address, dates of employment, pay frequency issue (with specific dates), and the amount of unpaid or incorrectly paid wages if applicable. Include copies of pay stubs, correspondence with your employer, and your documentation from Steps 1 and 2. The deadline for filing is generally 3 years from the date of the violation, though claims for willful violations may have a longer window. There is no filing fee.

Step 4: Investigation and Resolution. Once you file a complaint, the Missouri Department of Labor will investigate, typically within 30-60 days. An investigator will contact your employer for their response and may request additional documentation from both parties. The investigator will review your pay records, employment contract, and any written agreements about pay frequency. Expect to be interviewed about the violation and your employment history. The investigation process usually takes 60-90 days, though complex cases may take longer. The Department of Labor will issue a determination finding whether a violation occurred and, if so, calculating any wages owed plus penalties. If the employer does not comply with the determination, you have the right to pursue additional remedies.

Step 5: Legal Action and Attorney Consultation. If the Department of Labor investigation does not result in payment or if you wish to pursue additional damages, consult an employment attorney. Contact a Missouri employment law attorney (search through the Missouri Bar Association at mobar.org) who handles wage and hour cases. An attorney can evaluate whether you have grounds for a private lawsuit under Missouri law for unpaid wages, penalties, and potentially attorney's fees. Many employment attorneys work on contingency for wage claims, meaning they advance costs and are paid from your recovery. Your attorney can file a lawsuit in Missouri state court or, if federal law is also implicated, in federal court. Keep all documentation from previous steps to provide to your attorney immediately.
