Yes, you can sue an employer for paying you under the table, and federal law lets you recover double the unpaid minimum wage and overtime you’re owed, with the employer covering your attorney’s fees on top. You don’t need a written contract, pay stubs, or a W-2 to bring the case. The fact that you were paid in cash off the books doesn’t weaken your claim; if anything, it shifts some of the proof burden onto the employer who chose not to keep records.
What You Can Sue For
The Fair Labor Standards Act gives employees a private right of action against employers who violate minimum wage or overtime rules. If you were paid less than $7.25 per hour (or your state’s higher minimum), or you worked more than 40 hours in a week without time-and-a-half, you can file in federal or state court. The FLSA entitles you to the full amount of unpaid wages plus an equal amount in liquidated damages, which doubles your recovery.1Office of the Law Revision Counsel. 29 USC 216 – Penalties The court must also award reasonable attorney’s fees to a prevailing employee, so your lawyer gets paid by the employer rather than out of your check.
To make the numbers concrete: an employee paid $10 an hour in cash for 50-hour weeks over two years, with no overtime premium, is owed the half-time overtime rate on 10 hours a week for 104 weeks. That comes out to roughly $7,540 in back wages. Liquidated damages bring the total to around $15,080 before fees. If you were paid below minimum wage, the shortfall on every straight-time hour gets added on top.
Many employment attorneys take FLSA cases on contingency, charging nothing upfront and collecting through the court-ordered fee award. The FLSA also permits collective actions. If your coworkers were paid off the books too, one lawsuit can cover the group, which raises the stakes for the employer and often accelerates a settlement.
Breach of Contract
If your employer promised a specific pay rate, bonus, or benefit and didn’t deliver, you can add a breach of contract claim. A written contract isn’t required. Verbal agreements, texts, emails, and consistent past practice can establish the terms. These claims are harder to prove than FLSA claims because you have to show the promise and the breach, but they can cover money the FLSA doesn’t reach, like an agreed rate above minimum wage.
Small Claims as an Alternative
For smaller amounts, small claims court is faster and doesn’t need a lawyer. Limits vary by state, generally between $8,000 and $20,000. The tradeoff is that you give up the FLSA’s doubling of damages and its fee-shifting, so run the math before choosing this route.
How Long You Have To File
The FLSA sets a two-year statute of limitations from the date of each violation, extended to three years if the violation was willful, meaning the employer knew it was breaking the law.2Office of the Law Revision Counsel. 29 USC 255 – Statute of Limitations Paying workers off the books is almost always willful because the employer has to actively decide to skip payroll, so three years is the usual window in these cases.
Each paycheck is a separate violation with its own clock. Older weeks fall off the back end as time passes, so waiting costs you recoverable wages week by week. State wage laws sometimes allow longer periods, so a claim that’s stale under the FLSA may still be alive under state law.
How To Prove Your Hours Without Pay Stubs
The proof problem worries most off-the-books workers, but the law is on your side here. Because the FLSA requires employers to keep accurate wage and hour records, courts apply a relaxed standard when the employer failed to do so. You don’t have to prove your exact hours down to the minute. You need to give enough detail about your schedule that a fact-finder can reasonably approximate the unpaid amount. Vague statements won’t do it; a consistent, specific account of your regular week will.
Start gathering evidence before you file anything:
- Text messages with your employer or manager about shifts, pay, or complaints
- Screenshots of scheduling apps, group chats, or work assignments
- Bank deposits showing a recurring cash-in pattern
- Calendar entries, timestamped photos at the workplace, and location history
- A personal work log kept on your phone, the more contemporaneous the better
- Coworkers who can confirm your schedule and the pay arrangement
The Free Alternative: A Wage Complaint With the Department of Labor
You don’t have to sue to get paid. The Wage and Hour Division of the U.S. Department of Labor investigates minimum wage, overtime, and recordkeeping violations for free.3U.S. Department of Labor. Minimum Wage You file a complaint by phone or online, an investigator contacts the employer, and because off-the-books employers rarely have records, the investigator will typically build the case from your account and supporting evidence. If violations are confirmed, the WHD can order back wages directly, and many employers settle quickly once a federal agency is involved.
One tradeoff matters: if you file with the DOL and the Secretary of Labor decides to pursue the case, that cuts off your right to bring a private FLSA lawsuit for the same wages.1Office of the Law Revision Counsel. 29 USC 216 – Penalties For a straightforward wage recovery this is fine. If you want the doubled damages and attorney’s fees a private lawsuit produces, talk to an employment lawyer before filing with the DOL.
Retaliation Is Illegal, and the Claim Can Be Bigger Than the Wages
The FLSA makes it illegal for an employer to fire, demote, cut hours, or otherwise punish an employee for filing a complaint, participating in an investigation, or testifying about labor violations.4Office of the Law Revision Counsel. 29 USC 215 – Prohibited Acts The Department of Labor reads retaliation broadly, covering threats, schedule cuts, sending workers home without pay, and other actions that would discourage a reasonable worker from raising concerns.5U.S. Department of Labor. Retaliation
If your employer retaliates, you can recover lost wages, reinstatement, and an equal amount in liquidated damages.1Office of the Law Revision Counsel. 29 USC 216 – Penalties In practice, a wrongful termination often produces a bigger recovery than the original wage claim, because months of lost earnings add up faster than the underlying unpaid overtime.
Your Own Tax Situation
Suing your employer doesn’t erase your tax obligation on the money you were paid. Every dollar of cash wages is taxable income, and the responsibility to report it falls on you regardless of whether a W-2 ever gets issued. Cleaning this up before or alongside your claim protects you.
File IRS Form 4852 as a substitute W-2 when your employer won’t provide one. You estimate your wages and any taxes that should have been withheld using pay records, bank statements, or a prior W-2 from the same employer, and you explain what you did to try to get the missing W-2.6Internal Revenue Service. Using Form 4852 When Missing the Form W-2 or 1099-R Filing Form 4852 also builds your Social Security earnings record for the year, which the employer’s silence would otherwise leave empty.
If your employer misclassified you as an independent contractor when you were actually an employee, Form 8919 lets you pay only the employee’s share of Social Security and Medicare taxes instead of the full self-employment amount.7Internal Revenue Service. About Form 8919 – Uncollected Social Security and Medicare Tax on Wages You can also submit Form SS-8 to ask the IRS to formally determine your worker status.8Internal Revenue Service. About Form SS-8 – Determination of Worker Status
Skipping this piece has its own price. The IRS applies a 20% accuracy-related penalty on underpayments caused by negligence, and the same 20% applies as a substantial understatement penalty when the shortfall exceeds the greater of $5,000 or 10% of the tax you should have reported.9Internal Revenue Service. Accuracy-Related Penalty Interest runs on top. Filing amended returns voluntarily is almost always better than waiting for the IRS to catch it.
Reporting the Employer to the IRS for a Reward
Separately from your wage claim, you can report the employer’s tax evasion to the IRS whistleblower office. An employer paying off the books is skipping income tax withholding, employment taxes, and Social Security contributions, and the IRS pays informants for credible information about that.
Submit Form 211 with specific details: the employer’s name and address, taxpayer identification number if you have it, how you learned about the violations, and any supporting records like bank statements or communications about cash pay.10Internal Revenue Service. Submit a Whistleblower Claim for Award If the IRS acts on your information, the award is generally 15% to 30% of what the government collects.11Internal Revenue Service. Whistleblower Office You can’t file anonymously, but the IRS protects your identity from the employer during the investigation.
A wage lawsuit, a DOL complaint, and an IRS whistleblower claim can run in parallel; they target different violations and different remedies.
What Off-the-Books Work Is Costing You Beyond Wages
Cash pay with no reporting quietly drains benefits that depend on documented earnings:
- Social Security credits. In 2026, $1,890 in reported earnings buys one credit, and you can earn up to four a year. Every unreported year is a gap in the record that shrinks your future retirement or disability benefit, or leaves you short of eligibility entirely.12Social Security Administration. Quarter of Coverage
- Unemployment insurance. If the state has no record of your wages, it has no basis to approve a claim when the job ends.
- Workers’ compensation. Employers paying off the books usually don’t carry coverage for those workers, so a workplace injury lands on your own insurance or your own bank account.
Reporting the income yourself with Form 4852 preserves your Social Security record even when the employer refuses to cooperate.
What To Do This Week
Preserve evidence first. Screenshot text threads, export scheduling apps, save bank deposit records, and write out your regular hours while the memory is fresh. Ask a trusted coworker whether they’d confirm the arrangement.
Handle your taxes. File or amend using Form 4852, add Form 8919 if you were misclassified, and consider Form SS-8 for a formal status determination.
Then pick your enforcement path. A DOL complaint is free and requires no lawyer, but may block a private FLSA suit if the Secretary of Labor takes the case. A private lawsuit gets you doubled damages and employer-paid attorney’s fees, and most employment lawyers offer free consultations on contingency. An IRS whistleblower submission runs alongside either one. Whatever you choose, don’t wait: the statute of limitations is chewing through your recoverable weeks in the background.
