When to File a Wage Complaint
Here's the thing — the DOL's Wage and Hour Division recovers more than `$230 million` in back wages every year, and filing costs you nothing. The trigger is any time your employer pays less than the law requires: below the federal minimum of $7.25/hour (or your state's higher floor), skipping 1.5x overtime after 40 hours under FLSA § 207, off-the-clock work before or after shifts, illegal deductions that drop your effective wage below minimum, misclassification as exempt when your duties don't match, or stiffing you on the final paycheck after termination. Each one is a separate violation — you don't have to pick just one.
Wage theft is not a fringe problem — it is one of the most widespread forms of economic harm in the American labor market. A 2017 study by the Economic Policy Institute estimated that workers lose $15 billion annually to minimum wage violations alone, and overtime violations add billions more. The DOL's Wage and Hour Division recovers more than $230 million per year in back wages for workers. Despite these numbers, the majority of wage theft goes unreported because many workers do not know their rights or fear retaliation. If your employer owes you money, you have both the right and the law's protection to file a complaint.
Before filing, use our overtime pay calculator to determine whether you are being paid correctly for your overtime hours. If there is a discrepancy between what you should be earning and what you are receiving, that discrepancy is the basis for your complaint. For a broader overview of overtime laws, see our guide on overtime pay laws by state.
How to File with the Wage and Hour Division
Filing a complaint with the WHD is free and can be done in several ways. You can file online through the DOL's complaint portal, by calling the WHD toll-free helpline at 1-866-487-9243, or by visiting your nearest WHD office in person. The complaint process does not require an attorney, and the WHD investigator will handle the investigation on your behalf. You do not need to be a U.S. citizen to file a complaint — the FLSA protects all workers in the United States regardless of immigration status.
When you file, you will need to provide: your name and contact information (your identity is kept confidential unless disclosure is required for the investigation), your employer's name, address, and phone number, the type of work you do, how and when you are paid (hourly, salary, weekly, biweekly), the specific violation you are reporting (unpaid overtime, minimum wage, off-the-clock work, etc.), and the approximate dates and amounts involved. The more detail you provide, the stronger the foundation for the investigation. Attach copies of pay stubs, timesheets, employment contracts, and any other supporting documents.
After you file, a WHD investigator will be assigned to your case. The investigator will contact your employer to gather payroll records, time records, and other documentation. The investigation may take several weeks to several months, depending on the complexity of the case and the number of employees affected. You will be notified of the outcome. If the investigation finds violations, the WHD can order the employer to pay back wages, assess civil monetary penalties, and in willful cases, refer the matter for criminal prosecution.
What Happens During the Investigation
WHD investigations are thorough and employer-facing — you do not need to do much after filing your initial complaint. The investigator will visit or contact the employer, request payroll records, examine how the employer classifies its employees, and determine whether the employer is complying with the FLSA's minimum wage, overtime, recordkeeping, and child labor provisions. The investigation often extends beyond the individual complaint. If the investigator discovers that the employer is violating the law with respect to other employees — not just you — the investigation can expand to cover all affected workers.
This is a significant advantage of filing with the WHD rather than pursuing a private lawsuit. A single complaint from one worker can result in back pay recovery for dozens or even hundreds of co-workers who were subjected to the same illegal pay practices. The DOL has the authority to investigate the employer's entire workforce, not just the individual complainant. Some of the DOL's largest recoveries — involving millions of dollars in back wages — began with a single worker's complaint. The DOL newsroom regularly publishes press releases about enforcement actions that illustrate this multiplier effect.
During the investigation, continue to keep your own records of hours worked and wages received. If the employer changes its pay practices after learning of the investigation — for example, suddenly starting to pay overtime it had not been paying before — document the change. This can serve as evidence that the employer was aware of the violation. Do not discuss the pending investigation with your employer or co-workers unless the investigator instructs you to do so.
Protection Against Retaliation
One of the biggest concerns workers have about filing a wage complaint is fear of retaliation. The FLSA addresses this head-on: Section 215(a)(3) makes it illegal for any employer to "discharge or in any other manner discriminate against any employee because such employee has filed any complaint or instituted or caused to be instituted any proceeding under or related to this Act." This protection applies whether you file with the WHD, file a private lawsuit, or simply complain to your employer about unpaid wages. Even complaining to your co-workers about pay practices is protected activity under the FLSA.
If your employer retaliates against you for filing a wage complaint — by firing you, reducing your hours, changing your schedule, demoting you, or taking any other adverse action — you have a separate legal claim for retaliation that is independent of the underlying wage claim. Retaliation damages can include reinstatement, back pay, compensatory damages, and in some cases, liquidated damages. The WHD investigator can investigate retaliation claims as part of the same case. For more on recognizing and fighting retaliation, see our guide on workplace retaliation.
Your identity is kept confidential during the WHD investigation to the extent possible. The investigator will not disclose your name to the employer unless it is necessary for the investigation and you consent. In practice, however, if you are the only employee who was denied overtime, the employer may figure out who filed the complaint. This is why the retaliation protection is so important — even if the employer knows or suspects you filed the complaint, they cannot legally punish you for it. If they do, the retaliation claim often produces a larger recovery than the original wage claim.
Filing a State Wage Complaint Instead of (or In Addition to) Federal
Beyond the federal WHD, most states run their own wage and hour enforcement agencies that investigate unpaid wage complaints under state law. Filing a state complaint may be advantageous when: your state's minimum wage is higher than the federal minimum (true in more than 30 states as of 2025), your state has daily overtime requirements (such as California), your state provides stronger remedies (some states allow treble damages — triple the unpaid amount — for wage violations), or your employer is too small to be covered by the FLSA but is covered by state law.
You can file with both the federal WHD and your state agency simultaneously — the investigations will run in parallel, and the agencies may coordinate. In some cases, the state agency is better positioned to investigate because it has more investigators in your area or because state law provides stronger enforcement tools. The DOL's state labor office directory provides contact information for each state's wage enforcement agency.
Some states also allow you to file a private lawsuit directly without going through an administrative agency. In California, for example, employees can bring wage and hour claims under the Labor Code Private Attorneys General Act (PAGA), which allows individual workers to sue on behalf of the state and recover penalties that are shared between the employee, the state, and other affected workers. PAGA claims have become one of the most powerful wage enforcement tools in the country. Consult an employment attorney to determine whether a private lawsuit, an agency complaint, or both is the best strategy for your situation.
Statute of Limitations: Do Not Wait Too Long
The FLSA allows you to recover unpaid wages for two years prior to the date you file your complaint — or three years if the violation was willful (meaning the employer knew or should have known it was violating the law). This means that every week you delay filing is a week of back wages you may lose forever. If your employer has been shorting your overtime for four years, you can only recover the most recent two or three years' worth — and the clock is ticking backward from the date you file.
State statutes of limitations may be longer. California allows recovery of unpaid wages for three years under the Labor Code (or four years under the Unfair Competition Law). New York allows six years for unpaid wages under the New York Labor Law. These longer state deadlines can significantly increase the total amount you recover, particularly if the violations have been ongoing for years. An employment attorney can advise you on which statute of limitations applies to your specific claim.
Do not wait to file because you think you need a lawyer or because you are gathering more evidence. The WHD complaint process is designed to be accessible to workers without legal representation, and the investigator will gather evidence from the employer's records. Filing quickly preserves the longest possible recovery period and sends a signal to the employer that you are serious about enforcing your rights. If you want an estimate of what you may be owed before filing, use our overtime pay calculator or lost wages calculator to run the numbers based on your hours, pay rate, and the duration of the violation.
