Employment attorneys will tell you which agency to file with before they discuss anything else, and there is a reason for that. The federal Fair Labor Standards Act covers most private-sector workers, but your employer's size, your job classification, and your state all determine whether your claim belongs with the U.S. Department of Labor's Wage and Hour Division, your state labor board, or a private lawsuit. Get the routing wrong and you can lose months to a jurisdiction that cannot help you.
Recovering unpaid overtime or wages is not complicated once you understand the two-track system: federal law sets the floor, state law sometimes raises it, and the choice of agency shapes your timeline, remedies, and leverage. What most workers do not realize is that filing with the wrong agency is not just a paperwork problem. It can affect the statute of limitations on your claim.
This guide covers private-sector employees in the United States. It does not address federal government employees, railroad workers, or agricultural workers under H-2A visas, who have separate complaint procedures and are better served by an employment attorney familiar with those specific programs.
Understand What You Are Owed Before You File
The FLSA requires that most non-exempt employees receive overtime pay at 1.5 times their regular rate for hours worked beyond 40 in a workweek. That is the federal baseline. Several states, including California, set a higher bar: California requires daily overtime after 8 hours, not just weekly overtime after 40. If you work in a state with stronger protections, your state law governs and typically delivers a larger recovery.
Wages include more than your hourly rate or salary. According to the Department of Labor, wages can encompass accrued vacation pay (in states where it vests), final paychecks, commissions that were earned but not paid, and shift differentials promised in writing. The distinction between what was promised and what was actually paid is your claim's foundation. Gather your pay stubs, any written offer letters, employment contracts, and any texts or emails discussing your pay rate before you do anything else.
Or rather: gathering documents is not just helpful, it is the single most important thing you can do before filing, because the agency investigating your claim relies almost entirely on the records you provide. The DOL's Wage and Hour Division does not have subpoena power in every state-level enforcement context, and employers routinely argue that time records are inaccurate. Your records are your rebuttal.
Misclassification is the downside case most wage-claim guides skip past. If your employer classified you as an independent contractor or as an exempt salaried employee to avoid overtime, your claim is still valid, but it requires a different legal theory. Misclassification disputes are substantially more complex, often require an attorney, and should not be filed pro se through a standard DOL complaint form without at least a free consultation with an employment lawyer. The standard filing process described below assumes you were classified as a non-exempt employee but were simply not paid correctly.
Choose the Right Agency: Federal vs. State
Two primary filing tracks exist for private-sector wage claims in the United States.
The federal track means filing a complaint with the DOL's Wage and Hour Division (WHD). This is the right choice when your employer operates across multiple states, when your state labor board has limited enforcement resources, or when your claim involves a federal contractor. The WHD investigates complaints at no cost to the worker, can assess back wages and liquidated damages equal to the back wages owed, and does not require you to hire a lawyer. According to the DOL, the WHD recovered more than $270 million in back wages for workers in fiscal year 2022.
The state track means filing with your state's labor commissioner or department of labor. Many states, including California, New York, and Texas, have their own wage payment laws with enforcement agencies that can handle claims faster than the federal process and sometimes recover penalties that exceed the federal remedy. California's Labor Commissioner's Office, for example, can award waiting-time penalties of up to 30 days of wages when a final paycheck is deliberately withheld.
So which track should you use? I would start with your state agency if your state has a strong labor commissioner with a record of active enforcement. The state process tends to be faster, the remedies can be larger, and the investigator is physically closer to your employer. The federal track becomes the better choice when your employer is a federal contractor, when your state has weak enforcement, or when the dispute crosses state lines.
Quick reference: filing track decision
Use the following factors to choose your filing track before submitting a complaint.
| Factor | File with WHD (Federal) | File with State Agency |
|---|---|---|
| Employer type | Federal contractor, multi-state employer | Single-state private employer |
| Claim type | FLSA overtime, minimum wage | State wage law, waiting-time penalties |
| State enforcement strength | Weak state enforcement or no state wage law | Strong state labor commissioner (CA, NY, WA) |
| Timeline pressure | 2-year FLSA limit (3 if willful) | Varies by state; some as short as 1 year |
| Attorney required | No | No, but recommended for complex claims |
The timeline column matters more than most workers realize. FLSA claims have a two-year statute of limitations, extended to three years for willful violations. State deadlines vary and can be shorter. California allows three years for most wage claims; Texas allows two years for most. Missing a deadline extinguishes your right to file, so check your state's specific deadline before deciding which track to pursue.
How to File a Wage Claim: The Step-by-Step Process
The DOL's online complaint process is straightforward. Go to dol.gov, navigate to the Wage and Hour Division, and submit Form WH-4 (the online complaint form). You will need your employer's legal name and address, the dates of your employment, your job title, your hourly rate or salary, the specific pay periods in dispute, and an estimate of the wages you believe you are owed. The WHD accepts complaints online, by phone at 1-866-487-9243, or in person at a regional office.
For state filings, search for your state's labor commissioner or department of labor wage claim page. Most states have moved to online portals. The required information is similar to the federal form: employer details, employment dates, wages owed, and supporting documentation. California's Labor Commissioner accepts claims through the DLSE (Division of Labor Standards Enforcement) online portal. New York uses the Department of Labor's online wage claim system.
After you submit, expect a waiting period before an investigator contacts you. That puts it around 30 to 90 days for initial contact at the WHD, though complex cases take longer. Your employer will be notified and given an opportunity to respond. The investigator may request additional records from both sides.
But filing is not the end of your options. You can also hire an employment attorney and file a private lawsuit under the FLSA or state law. Private litigation often results in faster settlements and can add attorney's fees to your recovery, since the FLSA allows fee-shifting: a successful plaintiff can recover attorney's fees from the employer. The math here is worth understanding. If you are owed $4,000 in back wages, a private attorney working on contingency may recover that amount plus liquidated damages of $4,000 and attorney's fees, making the case viable even for a relatively small claim.
What Happens After You File
The WHD investigation is confidential. Your employer will not be told who filed the complaint, though in practice, if only one employee reported an issue, the employer may infer the source. The investigator reviews payroll records, time records, and employment agreements. If violations are found, the WHD will attempt to recover back wages through a settlement with the employer. If the employer refuses to cooperate, the DOL can file suit on your behalf or refer the case to the Solicitor of Labor.
The most common mistake workers make at this stage is stopping communication with their employer entirely and assuming the agency will handle everything. Keep your own records of any contact with your employer after filing. If your employer retaliates, including cutting your hours, demoting you, or firing you, that retaliation is itself a violation of the FLSA. Report retaliation to the same agency immediately. Retaliation claims are handled separately and can add substantial remedies to your original complaint.
What happens if you do nothing? Practically speaking: nothing. The employer keeps the money. The statute of limitations continues to run. Once it expires, your legal right to recover those wages is gone permanently. A $6,000 unpaid overtime claim that sits unfiled for three years under the FLSA is simply unrecoverable by federal process at that point, and your state deadline may have already passed. That is not a recoverable situation.
The framing that trips up most workers is thinking of a wage claim as a confrontation when it is actually an administrative process with real legal teeth. You are not accusing your employer of a crime. You are triggering a statutory process that exists specifically to correct underpayment, and agencies like the WHD pursue these on workers' behalf every day.
When to Get an Attorney Instead
Filing pro se through the DOL or a state agency works well for straightforward claims: a clear underpayment, documented hours, a responsive employer. But several situations call for an employment attorney before or instead of an agency complaint.
Misclassification disputes, class actions involving multiple coworkers, claims against employers who are actively destroying records, and retaliation situations all benefit from legal representation. Employment attorneys who handle wage claims typically work on contingency (no upfront fee) precisely because the FLSA's fee-shifting provision makes these cases financially viable for them. A free initial consultation costs you nothing and usually clarifies whether your case is complex enough to warrant representation.
The National Employment Law Project (nelp.org) and your state bar's lawyer referral service are reliable starting points for finding qualified employment attorneys. Legal aid organizations in most states also offer free consultations for workers below a certain income threshold. Check sq footage of your claim, your employer's size, and whether coworkers have the same issue first, since those three factors usually determine whether a class action is worth exploring.
And a note on retaliation: if you have already been fired or demoted after raising a pay concern internally, do not file the wage claim yourself. Get an attorney. Retaliation cases are more complex, the damages can be substantially larger, and the procedural steps for preserving a retaliation claim differ from a standard wage complaint.
File Before the Clock Runs Out
If you believe you are owed unpaid wages or overtime, file your complaint with the WHD or your state labor agency now, not after you have gathered every possible document. You can supplement your complaint with additional records after submission. What you cannot do is recover wages after the statute of limitations has passed.
For most FLSA claims, the two-year window starts running from each pay period you were underpaid, not from your last day of work. A claim for three years of unpaid overtime filed today only recovers two years of back pay under federal law (three if the violation was willful). Every month you wait is a month of potential recovery you permanently give up.
If your situation involves misclassification, a federal contractor employer, or retaliation, contact an employment attorney through your state bar referral service or NELP before filing. The agency complaint and the private lawsuit are not mutually exclusive, but the sequence matters, and an attorney can advise you on which to lead with in your specific state.
