Bonus Pay Laws in Michigan: When Bonuses Must Be Paid

Federal law provides limited protection for bonus payments. The Fair Labor Standards Act (FLSA) (29 U.S.C. § 201 et seq.) requires employers to pay earned wages, but does not specifically define or mandate bonus payments. The Department of Labor (DOL) takes the position that bonuses, including discretionary bonuses, are wages if they are part of the employment agreement or if the employer's compensation plan promises them. However, the FLSA leaves significant room for state law to impose stricter requirements.

Under federal law, bonuses earned for productivity, sales, or performance targets must be paid if they were promised as part of compensation. The FLSA applies to employers with at least two employees engaged in interstate commerce. Remedies under the FLSA include back pay plus an equal amount in liquidated damages, plus attorney's fees and costs. The Wage and Hour Division (WHD) of the DOL enforces federal wage claims, though private lawsuits are also permitted. Employers can challenge bonus claims by proving the bonus was purely discretionary and not part of the compensation formula.

Michigan's Wage and Fringe Benefits Act (MCL 408.391) provides substantially stronger protection for bonuses than federal law. Under this statute, wages include all compensation paid to an employee for employment, including bonuses, commissions, and incentive payments promised by the employer. Michigan law applies to all employers with at least one employee, with no interstate commerce threshold, making it far broader than the FLSA.

Michigan distinguishes between discretionary and non-discretionary bonuses more rigidly than federal law. If an employer's compensation plan or employment agreement specifies that bonuses will be paid based on meeting targets, profit-sharing, or other defined metrics, those bonuses are legally classified as earned wages and must be paid. The employer cannot later claim the bonus was discretionary if the original agreement promised it. This is codified in Michigan case law establishing that bonuses promised as part of the compensation package are enforceable wage obligations.

Michigan employers cannot reduce or withhold bonuses as a disciplinary measure unless the bonus plan explicitly reserves that right in writing and the employee received notice before the conduct occurred. The state treats such withholding as an unlawful wage deduction. Additionally, Michigan does not require bonuses to be paid in a particular timeframe—they must be paid at the next regular pay period following when they became earned or vested, or within 30 days if no regular pay schedule applies. If an employer violates these requirements, employees can file a wage claim with the Michigan Department of Labor or sue in court for unpaid wages.

Michigan's remedies are more generous than federal law. Employees can recover unpaid bonuses plus a penalty of 10 percent of the unpaid amount or $500, whichever is greater, under MCL 408.398. The statute of limitations for wage claims is 6 years, compared to 3 years under the FLSA (or 2 years for willful violations). Michigan also provides for recovery of attorney's fees and court costs, and the burden shifts to the employer to prove the bonus was not earned or that a valid exception applies.

Unpaid bonus claims in Michigan do not expire for 6 years (MCL 408.390).

Employees can request wage investigation by the Michigan Department of Labor at any time wages were unpaid.

Penalty for unpaid bonuses: 10% of unpaid amount or $500 minimum, whichever is greater (MCL 408.398).

No minimum employee threshold—Michigan wage law applies to employers with one or more employees.

Bonuses must be paid within the next regular pay period or within 30 days if no regular pay schedule exists.

Michigan law recognizes narrow exceptions to bonus payment obligations. The primary exception is that genuinely discretionary bonuses—where the employer retains sole discretion to award or deny the bonus with no contractual obligation—do not constitute wages and need not be paid. However, this exception is heavily scrutinized. If any employment agreement, offer letter, job posting, personnel handbook, or compensation plan contains language suggesting the bonus will be paid upon achievement of specified metrics, the bonus is presumed non-discretionary. The employer bears the burden of proving discretion was retained.

Bonuses tied to termination or post-employment events are subject to limitations. If an employment contract specifies that bonuses are forfeited upon termination without cause, that forfeiture may be enforceable if clearly disclosed, though Michigan courts have been skeptical of forfeiture clauses that apply to already-earned bonuses. A bonus earned during employment cannot be clawed back after termination if the employee met the performance conditions during their tenure, even if they left before payout. Michigan courts have held that employers cannot condition previously earned bonuses on the employee's continued employment unless that condition was explicit and conspicuous in the original agreement.

Bonuses subject to compliance conditions are enforceable exceptions if the condition was disclosed in advance. For example, if a bonus plan states that bonuses require the employee to have no disciplinary violations or to maintain a certain attendance record, and this was disclosed in writing before the performance period, the employer can withhold the bonus if conditions are not met. However, the employer cannot retroactively impose new conditions or change the rules mid-performance period.

When an employee is terminated for misconduct, bonuses earned prior to termination must still be paid unless the bonus plan explicitly permits forfeiture for that category of misconduct and the policy was provided in writing. At-will employment does not override wage obligations—being at-will does not permit an employer to refuse to pay earned wages as a form of discharge.

Step 1: Document the bonus promise and non-payment. Keep copies of the job offer letter, employment contract, written job description, employee handbook, compensation plan, email communications referencing the bonus, and evidence of performance meeting the bonus criteria (sales records, project completion dates, performance reviews, emails from management confirming achievement). Maintain records of pay stubs showing what was paid versus what was promised. Take screenshots of internal systems, performance databases, or communications before the employer deletes records. Retain all documentation showing when the bonus should have been paid and how much.

Step 2: Attempt an internal complaint if feasible. Write a formal email to your HR department or manager dated and timestamped, clearly stating the bonus amount promised, the performance metric or date it was earned, when it should have been paid, and requesting payment within 10 business days. Use language like "I am entitled to payment of the earned bonus of $[amount] under our employment agreement" rather than asking for reconsideration. Keep the email brief and factual. Request written confirmation of receipt. If HR responds orally, follow up with an email summarizing the conversation. This internal step is not legally required but creates evidence and sometimes prompts payment. Do not threaten legal action at this stage—simply state the fact and the request.

Step 3: File a wage complaint with the Michigan Department of Labor & Economic Opportunity (DLEO). Visit the DLEO website at michigan.gov/leo and locate the Wage and Hour Division complaint form. Alternatively, call the DLEO Wage and Hour Division at 517-335-3485 or toll-free 1-800-285-9003. Complete the wage complaint form providing: your name, address, and phone; employer name, address, and phone; dates of employment; description of the bonus promised and basis (written contract, verbal agreement, handbook policy); dates performance was met and when bonus should have been paid; amount owed; and whether you are still employed. The complaint is free. Submit online, by mail to the Michigan DLEO, or by phone. There is no filing fee and no statute of limitations bar—you can file for bonuses unpaid up to 6 years ago. The DLEO will assign a wage investigator to your case.

Step 4: Expect the investigation process to take 30-60 days. The DLEO investigator will contact your employer requesting pay records, the compensation plan, and the employer's version of events. The employer is required to provide records. You may be asked to provide additional documentation such as your employment contract, performance reviews, or emails. The investigator will determine whether the bonus was earned and promised, and whether payment was made. If the DLEO finds a violation, they will issue a determination letter and may demand payment of the unpaid bonus. The employer has the right to appeal the DLEO determination within 10 days. During this time, continue collecting evidence and communicate in writing with the employer only.

Step 5: Consult an employment attorney if the DLEO determination is not satisfied or if the bonus amount is substantial (over $5,000). Contact a Michigan employment law attorney who specializes in wage and hour or contract disputes. Many will offer free initial consultations. Bring all documentation, DLEO correspondence, and any correspondence with the employer. An attorney can file a civil lawsuit in Michigan district or circuit court for unpaid bonuses under MCL 408.398, seeking the unpaid bonus amount plus 10% penalty (or $500 minimum) plus attorney's fees and court costs. The statute of limitations is 6 years, so there is time to pursue litigation even if the DLEO process takes months. Your attorney can also demand that the employer preserve all payroll records and communications. Litigation typically takes 6-18 months to resolve.
