Bonus Pay Laws in Missouri: When Bonuses Must Be Paid

Federal law does not mandate employers offer bonuses at all. However, the Fair Labor Standards Act (FLSA), 29 U.S.C. § 201 et seq., requires that all compensation promised to an employee must be paid timely and cannot be withheld improperly. The U.S. Department of Labor enforces the FLSA and treats promised bonuses as part of an employee's wages if they are a condition of employment or promised through an employment contract.

Under the FLSA, if a bonus is promised—whether discretionary or not—the employer cannot unlawfully withhold it or use it as a penalty for lawful conduct. Bonuses that are part of an incentive plan, sales commission structure, or employment agreement are wages. Federal law allows the FLSA to be enforced through civil litigation by the employee or DOL investigation, with remedies including back pay, liquidated damages equal to unpaid wages, and attorney's fees. There is a two-year statute of limitations for FLSA wage claims (three years if willful).

Missouri Revised Statutes § 290.110 defines wages broadly to include all compensation for labor or services, including bonuses. Missouri law does not distinguish between 'discretionary' and 'non-discretionary' bonuses when the bonus has been promised to an employee or is part of an employment contract or agreement. Once a bonus is promised—whether orally or in writing—it becomes part of the employee's wages and the employer has a legal obligation to pay it.

Under Missouri law, bonuses must be paid when due according to the terms of the promise or agreement. If an employee is terminated and has earned a bonus, Missouri Revised Statutes § 290.140 requires the employer to pay all earned wages, including bonuses, at or before the next regular payday or within 30 days of termination, whichever is sooner. This is stricter than federal law in that Missouri specifies an exact timeline for final wage payment.

Missouri's wage laws apply to all employers in the state, including private employers, nonprofits, and government entities, regardless of size. There is no employee-count threshold for coverage under § 290.110. If an employer has promised a bonus and fails to pay it, the employee can file a wage claim with the Missouri Department of Labor and Industrial Relations (DOLIR). This state process is more accessible than federal litigation because there is no requirement to prove willfulness or file in court; the DOLIR investigates wage claims at no cost to the employee.

Missouri's law is generally comparable to federal law but provides clearer enforcement through a state administrative process. The state explicitly requires final bonus payment within 30 days of termination, which is more specific than the federal 'prompt and final' standard. Missouri does not require employers to offer bonuses, but once promised, the obligation is clear and enforceable.

Missouri law contains important exceptions and limitations on bonus claims. First, truly discretionary bonuses—those awarded at the sole discretion of the employer with no promise, agreement, or established practice—may not be enforceable as wages in some circumstances, though Missouri courts still require clear evidence that the bonus was truly discretionary and not conditional on any performance.

Second, if a bonus is expressly conditioned on meeting specific business metrics or profit targets that were not met, an employer may argue the bonus was not 'earned' and thus not owed as a wage. However, the employer must prove the condition was not satisfied; vague or subjective performance conditions are interpreted against the employer.

Third, forfeiture clauses in employment agreements may be challenged under Missouri law if they appear to be a penalty for lawful conduct (such as leaving the job) rather than a legitimate condition of earning the bonus. Missouri disfavors forfeiture provisions and will not enforce overly harsh or retaliatory bonus clawback terms.

Fourth, statute of limitations: claims must be filed within two years of the date the bonus was due. If an employee delays longer, the claim is barred. Finally, if a bonus is explicitly labeled as 'discretionary' in the employment agreement and the agreement clearly states the employer makes final decisions on award amounts with no guarantee, the employee may have difficulty establishing an enforceable right to the bonus, though this depends on the specific language and any prior payment history.

**Step 1: Document the Bonus Promise.** Collect all evidence that a bonus was promised. This includes written employment contracts, offer letters, employee handbooks, email exchanges with management, text messages, witnesses to oral promises, and any written bonus plans or commission structures. Keep dates, amounts promised, conditions for earning the bonus, and when the bonus was supposed to be paid. Write down the names and dates of any conversations about the bonus.

**Step 2: Make an Internal Complaint.** Before filing an external claim, request the unpaid bonus in writing from your employer or HR department. Send an email or letter stating: the bonus amount, the date it was due, the basis for the promise (contract, handbook, oral agreement with named manager), and a request for payment within 10 days. Keep a copy and send via email with read receipt if possible. This creates a clear record and sometimes prompts immediate payment. If the employer denies the bonus or does not respond within 10 business days, proceed to Step 3.

**Step 3: File a Wage Claim with the Missouri Department of Labor and Industrial Relations.** Visit the Missouri DOLIR website at labor.mo.gov or call 573-751-3976. You can file a wage claim online through their system or by mail. Provide: your name and contact information, the employer's name and address, the dates of employment, the amount of the bonus, the date it was due, documentation of the promise, and any correspondence with the employer about the bonus. There is no filing fee. The deadline is two years from the date the bonus was due, so file as soon as possible. The DOLIR will send the claim to the employer and request a response.

**Step 4: Participate in the Investigation Process.** The Missouri DOLIR will investigate your claim. You may be asked to provide additional documentation or participate in a phone interview. The employer will be given an opportunity to respond. The investigation typically takes 30–90 days, though complex cases can take longer. You will be notified in writing of the outcome. If DOLIR finds in your favor, the employer is ordered to pay the unpaid bonus plus any accrued interest. If the employer does not pay the wage order, DOLIR can pursue enforcement, including wage garnishment or liens.

**Step 5: Consult an Attorney if Necessary.** If the DOLIR claim is denied, or if the bonus amount is very large (over $5,000), or if you believe the employer retaliated against you for demanding the bonus, consult an employment attorney licensed in Missouri. An attorney can file a civil lawsuit in Missouri state court under § 290.530 to recover the unpaid bonus, plus penalties, interest, and attorney's fees. Many Missouri employment attorneys offer free consultations and work on contingency (you pay nothing unless you win).
