California Labor Code section 221 makes it illegal for an employer to collect or receive from an employee any part of wages already paid. That bar applies even when the employer overpaid by mistake. To get the money back, the employer needs either the employee’s written consent or a court judgment, and unilateral payroll deductions expose the employer to civil penalties starting at $100 per affected worker.1California Legislative Information.

What Section 221 Forbids
The statutory language is short and absolute: no employer may “collect or receive from an employee any part of wages theretofore paid.”1California Legislative Information. California Code Labor Code 221 – Payment of Wages The Division of Labor Standards Enforcement, which enforces California wage law, warns that an employer who “resorts to self-help does so at its own risk.”2Department of Industrial Relations. Deductions From Wages
That reaches situations employers routinely assume they can handle in-house. A short cash register drawer. A customer returning merchandise after the salesperson earned commission. A payroll glitch that doubled someone’s check. California courts treat losses from ordinary negligence or accident as a cost of doing business, not something the employer can push onto the worker’s next paycheck.2Department of Industrial Relations. Deductions From Wages
The Narrow Exceptions
Labor Code section 224 lists the only deductions from wages an employer may make:3California Legislative Information. California Code Labor Code 224 – Payment of Wages
- Deductions required by state or federal law, such as income tax withholding, Social Security, and court-ordered garnishments.
- Deductions the employee has expressly authorized in writing, covering items like insurance premiums or hospital dues. The written authorization cannot amount to a rebate of a wage set by a collective bargaining agreement or statute.
- Deductions for health, welfare, or pension contributions expressly authorized by a collective bargaining or wage agreement. A collective bargaining agreement, on its own, cannot authorize recovery of an overpayment.2Department of Industrial Relations. Deductions From Wages
None of these categories mention overpayment recovery. That silence is the point. Section 221 was written to make paycheck clawbacks difficult, and section 224 does not open a back door.
How Employers Can Lawfully Recover an Overpayment
Two paths exist. The first works only if the employee agrees.
Voluntary Written Authorization
The employer can ask the employee to sign a written agreement permitting repayment through future payroll deductions. The DLSE has confirmed that such deductions are lawful when the employee gives genuine written consent and, after each deduction, still receives at least the minimum wage for every hour worked in the pay period.4Department of Industrial Relations. Wage Deduction Authorization For Overpayments Due to Payroll Error California’s minimum wage rises to $16.90 per hour on January 1, 2026, and no deduction can drop the worker’s effective hourly rate below that floor.5Department of Industrial Relations. Minimum Wage
The written authorization should spell out the total overpayment, the amount deducted each pay period, and how long the deductions will continue. Vague or coerced authorizations do not hold up. Burying the language in onboarding paperwork or pressuring a worker to sign creates its own liability.
Civil Lawsuit
If the employee refuses to sign, the employer’s remaining option is court. The employer files a civil action, typically on a theory like unjust enrichment, and enforces any judgment through the ordinary legal process. The California Supreme Court’s decision in CSEA v. State of California confirms that an employer cannot bypass the wage garnishment laws by unilaterally deducting from current paychecks to recover past salary overpayments, even where a general statute appears to allow the offset.6Department of Industrial Relations. Payroll Deductions and Offsets Against Wages
The statute of limitations for a claim based on mistake is three years under Code of Civil Procedure section 338. An employer that sits on the error too long can lose the right to sue.
Final Paychecks: Even Tighter
The rules constrict when employment ends. In Barnhill v. Sanders, a California appellate court held that an employer cannot set off debts owed by an employee against the employee’s final wages.2Department of Industrial Relations. Deductions From Wages Even when the worker previously signed a written installment agreement, the employer can take only one installment from the final paycheck. Sweeping the entire remaining balance out of a departing employee’s last check is unlawful, no matter what the authorization says.
For any balance left after that last installment, the employer’s only route is a civil lawsuit. Deducting the full balance from a final paycheck exposes the employer to both section 225.5 penalties and waiting time penalties under section 203.
The Salaried Exempt Trap
Employers who try to claw back overpayments from salaried exempt workers face a separate federal problem. Exempt employees must receive their full predetermined salary for any week in which they perform work, and deductions are permitted only in a short list of circumstances such as full-day personal absences or safety rule violations.7U.S. Department of Labor. Salary Basis Requirement and the Part 541 Exemptions Under the Fair Labor Standards Act Overpayment recovery is not on the list.
A pattern of improper deductions from exempt salaries can destroy the overtime exemption for every employee in the same job classification under the same managers, converting a payroll fix into a much larger overtime bill. A safe harbor exists when the employer maintains a clearly communicated policy against improper deductions, reimburses any that occur, and commits to future compliance; isolated or inadvertent mistakes that get corrected will not sink the exemption.7U.S. Department of Labor. Salary Basis Requirement and the Part 541 Exemptions Under the Fair Labor Standards Act
Penalties for Unlawful Deductions
Labor Code section 225.5 sets the civil penalties. A first violation costs $100 for each employee whose pay was improperly withheld. Any subsequent violation, or a willful or intentional first violation, costs $200 per affected employee plus 25 percent of the amount unlawfully withheld.8California Legislative Information. California Code Labor Code 225.5 – Penalty for Unlawful Withholding of Wages The Labor Commissioner recovers those penalties through a wage claim hearing or through an independent civil action.
An unlawful deduction from a final paycheck can also trigger waiting time penalties under Labor Code section 203. When an employer willfully fails to pay all wages due at separation, the worker’s daily wages keep accruing as a penalty from the date they were owed, up to 30 days.9Department of Industrial Relations. Waiting Time Penalty For a well-paid worker, 30 days adds up quickly. A prevailing employee can also recover reasonable attorney’s fees and costs.
Filing a Wage Claim
An employee who believes an employer made an unauthorized deduction can file a wage claim online with the Labor Commissioner’s Office (the DLSE).10Division of Labor Standards Enforcement. How to File a Wage Claim The filing triggers an investigation and can lead to a hearing where the employer has to justify the deduction. If the deduction was not lawful, the DLSE can order the wages returned along with penalties.
The deadline is three years from the date of the deduction.10Division of Labor Standards Enforcement. How to File a Wage Claim Missing it forfeits the right to recover through the Labor Commissioner, though a civil lawsuit may still be available depending on the facts.
