Unpaid Wages Laws — Your Rights & How to Recover Pay

Unpaid-wage law is broader than a single calculator formula. Federal law focuses heavily on minimum wage and overtime, while state wage-payment laws can govern additional compensation, deductions, final pay, and claim procedures. This guide explains those legal categories; use the calculator pages only for the arithmetic.

Key distinction: The FLSA provides federal minimum-wage, overtime, recordkeeping, and anti-retaliation protections. Not every dispute over a bonus, commission, deduction, PTO policy, or final paycheck is an FLSA claim; many of those rights come from state law, a contract, or an employer policy.

What Counts as Unpaid Wages?

“Unpaid wages” can describe several different problems. The legal source of the right matters because the formula, remedy, and deadline can differ.

The Fair Labor Standards Act: What Federal Wage Law Covers

The FLSA is a federal baseline for covered employment. Among its core protections are:

The FLSA is not a general federal contract-enforcement law for every type of promised compensation. State wage-payment statutes and contracts may control disputes involving commissions, PTO, deductions, pay frequency, and final wages.

Common Unpaid-Wage Problems

A payroll discrepancy is not automatically the same legal claim in every state. Before calculating penalties or filing deadlines, identify whether the issue is federal minimum wage/overtime, state wage payment, contract compensation, or another category.

Final Paycheck Laws Are Mostly State-Specific

Federal law does not generally require an employer to issue a former employee’s final paycheck immediately. The U.S. Department of Labor notes that some states impose faster final-pay deadlines, so the applicable state rule matters.

California example

California generally requires a discharged employee to receive earned wages, including accrued vacation when applicable, at termination. An employee who quits with at least 72 hours’ notice is generally due final wages at quitting; without that notice, final wages are generally due within 72 hours. California waiting-time penalties may apply to a willful failure to pay wages due on time, subject to statutory conditions and defenses, and can accrue for up to 30 days. Use the California Waiting Time Penalty Calculator to estimate the separate potential §203 amount when qualifying final wages were paid late.

Claim Deadlines: Federal and State Rules Differ

For FLSA minimum-wage and overtime back-pay claims, the general federal limitations period is two years, extended to three years for willful violations. State wage-payment, contract, penalty, retaliation, and final-pay claims can use different deadlines.

Do not select a deadline simply because it is the longest number in a state table. Different legal theories can have different filing requirements, and filing one type of complaint may not preserve another claim.

What Can Be Recovered in an Unpaid-Wage Claim?

The answer depends on the legal basis for the claim.

State-law remedies

State law may provide different damages, statutory penalties, interest, waiting-time penalties, or other remedies. California PAGA is a separate civil-penalty mechanism; penalty amounts depend on the violation and the 2024 reforms created new standing, cure, allocation, and penalty-reduction rules. It should not be added to every wage claim as a flat per-pay-period number.

How to Investigate an Unpaid-Wage Claim

  1. Identify the missing compensation: list the affected pay periods, hours, rates, commissions, deductions, or final-pay items.
  2. Gather records: keep pay stubs, time records, schedules, compensation plans, offer letters, and written communications.
  3. Use the matching calculator: the Unpaid Wages Calculator handles missing straight-time hours; the Overtime Pay Calculator handles overtime arithmetic; the Minimum Wage Underpayment Calculator handles direct minimum-wage shortfalls.
  4. Compare the estimate with payroll: document the discrepancy in writing and keep the employer’s response.
  5. Identify the governing law: determine whether the issue is an FLSA claim, a state wage-payment claim, contract compensation, or another category before choosing a filing route.
  6. Check the deadline: federal and state claims can use different limitation periods and procedures.
  7. Choose the appropriate enforcement route: the U.S. DOL Wage and Hour Division handles covered FLSA matters; state labor agencies and courts address state-law rights.

Frequently Asked Questions

What are unpaid wages?

Unpaid wages are compensation that became due under the applicable law, contract, or compensation plan but was not fully paid. Examples can include missing compensable hours, unpaid overtime, minimum-wage shortfalls, earned commissions, worked-through auto-deducted time, or final wages. Different categories can be governed by different rules.

Are unpaid wages illegal?

Failing to pay compensation required by applicable wage law can violate federal or state law. The FLSA primarily provides federal minimum-wage and overtime protections; many additional pay-frequency, deduction, commission, PTO, and final-pay rights come from state law or contracts.

How far back can unpaid wages be claimed?

For FLSA minimum-wage and overtime back pay, the general federal limitations period is two years and extends to three years for willful violations. Other wage claims can use different state or contract deadlines, so the correct period depends on the legal theory and jurisdiction.

Do unpaid wages include overtime?

Yes, unpaid overtime can be a form of unpaid wages. Under the FLSA, covered non-exempt employees generally receive at least 1.5× the regular rate for hours over 40 in a workweek. State law can add separate overtime protections.

What damages can I recover for unpaid wages?

For covered FLSA minimum-wage or overtime claims, a private action can seek back wages, an equal amount as liquidated damages, and reasonable attorney’s fees and court costs. State-law remedies vary and can include different penalties or interest. California PAGA penalties are fact-specific rather than a universal flat amount.

What is the FLSA?

The Fair Labor Standards Act is the federal law that establishes minimum-wage, overtime, recordkeeping, child-labor, and anti-retaliation protections for covered employment. It does not govern every possible dispute over promised compensation.

Can I claim unpaid wages after leaving a job?

Leaving a job does not by itself erase wages or other compensation that was already legally due. Whether a claim remains timely depends on the applicable federal, state, contract, or other limitation period.

What is a wage violation?

A wage violation is a failure to comply with an applicable wage-and-hour requirement. Examples can include minimum-wage or overtime violations, failure to pay compensable hours, unlawful deductions, certain final-pay violations, recordkeeping violations, or retaliation. The specific legal source and remedy vary by issue.

Is this article legal advice?

No. This guide provides general information and does not determine which federal or state claim applies to a particular worker. Wage-payment rules, deadlines, exemptions, and remedies vary by jurisdiction and facts.
