California Bonus Pay Laws: Overtime, Clawbacks & Penalties

California bonus pay laws treat most bonuses as wages, which means employers must factor them into overtime, pay them on time, list them correctly on wage statements, and, starting January 1, 2026, follow new rules on sign-on bonus repayment clauses. Get any of this wrong and the penalties stack fast: waiting time penalties, wage statement penalties, and PAGA claims can all attach to the same underpaid bonus.

Discretionary or Non-Discretionary: The Classification That Drives Everything

Whether a bonus is discretionary or non-discretionary determines whether it counts as wages, whether it affects overtime, and whether late payment triggers penalties. This is the first question to answer for any bonus arrangement.

A non-discretionary bonus is tied to measurable criteria the employee can point to: a sales target, an attendance record, a production quota, a profitability threshold, or continued employment through a specific date. Because the employee earns it by meeting a standard, California’s Division of Labor Standards Enforcement treats it as wages that must be included in the regular rate of pay for overtime purposes.¹ Once the criteria are met, the employer cannot withhold payment. In Marin v. Costco Wholesale Corp. (2008), a California appellate court affirmed that overtime on a production-based bonus formula must be computed and paid in accordance with the pay period rules of Labor Code Section 204.²

A truly discretionary bonus is one the employer decides to give without any prior promise or formula. Holiday gifts and spontaneous rewards are the standard examples. Because the employee has no way to earn them by hitting a target, they are not wages and do not enter the overtime calculation.¹

The line is thinner than it looks. A year-end bonus paid every December can create an implied obligation once employees come to expect it. The safest approach is to document each discretionary bonus in writing at the time of payment, stating clearly that it was not promised, not tied to any formula, and creates no expectation of future payments.

Incentive bonuses tied to sales, retention, or other goals are a subset of non-discretionary bonuses and get the same wage treatment. Note one boundary: Labor Code Section 2751 requires written contracts for commission arrangements, but it explicitly excludes short-term productivity bonuses, variable incentive payments that only increase compensation, and profit-sharing plans.³ Even so, putting any bonus arrangement in writing prevents disputes about what was promised.

How Bonuses Change Overtime Pay

Every non-discretionary bonus has to be folded into the regular rate of pay for overtime calculations, and the method depends on the type of bonus. Overtime attributable to a bonus must be paid in the pay period following the end of the bonus-earning period.¹

Flat-Sum Bonuses

A flat-sum bonus is a fixed dollar amount, like a $500 attendance bonus. In Alvarado v. Dart Container Corp. of California (2018), the California Supreme Court held that flat-sum bonuses must be divided by the number of non-overtime hours worked during the bonus-earning period. That per-hour value is then multiplied by 1.5 (or 2.0 for double-time hours) and applied to every overtime hour worked.¹

An example: an employee earns a $30 flat-sum bonus in a week with 40 regular hours and 8 overtime hours. Divide $30 by 40 non-overtime hours for $0.75 per hour. Multiply by 1.5 to get $1.125, then by 8 overtime hours, for $9.00 in additional overtime pay attributable to the bonus. Using total hours (48) as the divisor would shortchange the employee and violate California law.

Production Bonuses

Production bonuses reward output on a per-hour basis. Divide the bonus by total hours worked (including overtime) during the earning period to find the per-hour bonus rate. Because the straight-time value is already in the payment, the employer owes only the overtime premium: 0.5 times the per-hour rate for time-and-a-half hours, and 1.0 times for double-time hours.¹

Percentage-Based Bonuses

A bonus calculated as a percentage of total earnings is already proportional to all hours worked. The bonus still must be included in total compensation before the overtime rate is recalculated, but the adjustment is smaller than with flat-sum or production bonuses.

When Bonuses Must Be Paid

Earned bonuses are wages, so they follow California’s wage payment deadlines. Under Labor Code Section 204, wages earned between the 1st and 15th of the month must be paid by the 26th, and wages earned between the 16th and the last day of the month must be paid by the 10th of the following month. For weekly or biweekly schedules, payment must be made within seven calendar days after the end of the payroll period.⁴

Bonuses tied to a specific pay period follow that same schedule. Bonuses calculated over longer periods, such as quarterly or annual performance bonuses, must be paid as soon as the amount becomes calculable.

Final Paychecks and Bonuses

When an employee is discharged, all earned wages, including any bonus that can be calculated at that point, are due immediately under Labor Code Section 201.⁵ When an employee resigns, final wages are due within 72 hours under Labor Code Section 202, or on the last day of work if the employee gave at least 72 hours of advance notice.⁶

What happens when an employee leaves mid-way through a bonus-earning period is the harder question. If the bonus terms allow proration and the employee met the performance standards, a prorated portion may be owed as earned wages. Vague language about when a bonus is “earned” tends to get resolved in the employee’s favor under California law, which is why written bonus agreements pay for themselves.

Sign-On Bonus Clawbacks Under the 2026 Rules

Effective January 1, 2026, California’s AB 692 places significant restrictions on “stay-or-pay” arrangements, including sign-on bonuses with repayment clauses. The law adds Section 16608 to the Business and Professions Code and limits an employer’s ability to claw back a sign-on bonus when an employee leaves before a specified retention period.

For a sign-on bonus clawback to be enforceable under the new law, the employer must meet all of the following:

The repayment terms must appear in a standalone document, not buried in the main employment contract.
The employee must be told they have the right to consult an attorney and given at least five business days to do so before signing.
Any repayment obligation cannot accrue interest and must be prorated based on the remaining retention period, which cannot exceed two years from when the employee received the payment.
The employee must have the option to defer the bonus until the end of the retention period, eliminating repayment risk entirely.
Repayment can be required only if the employee voluntarily resigns or is terminated for misconduct as defined under Unemployment Insurance Code Section 1256.

One important boundary: mid-employment retention bonuses with clawback provisions are not covered by this exemption framework, which makes them considerably riskier to enforce. Any employer using sign-on or retention bonus agreements with repayment terms should review them against these requirements before extending offers in 2026.

Tax Withholding on Bonus Payments

Bonuses are supplemental wages, and both federal and California rules require specific withholding treatment.

Federal Withholding

When a bonus is paid separately from regular wages and the total stays under $1 million for the calendar year, the employer can either withhold federal income tax at a flat 22% or use the aggregate method, adding the bonus to the regular paycheck and withholding as if the combined amount were a single payment for that pay period. Supplemental wages above $1 million in a calendar year are subject to a mandatory 37% withholding rate on the excess.⁷

Social Security tax applies at 6.2% up to the 2026 wage base of $184,500. Once cumulative earnings exceed that threshold, Social Security tax stops, but Medicare tax at 1.45% continues with no cap.⁸

California State Withholding

The Employment Development Department applies a flat 10.23% state withholding rate to bonuses and stock option payments, and 6.6% to other supplemental wages.⁹ These rates apply regardless of which federal method the employer chooses.

Wage Statements Must Reflect Bonus-Adjusted Rates

Labor Code Section 226(a) requires an itemized wage statement covering nine categories: gross wages, total hours worked, piece-rate details if applicable, all deductions, net wages, the pay period dates, the employee’s name and last four digits of their Social Security number (or an employee ID), the employer’s legal name and address, and all hourly rates in effect during the pay period with the corresponding hours worked at each rate.¹⁰

When a non-discretionary bonus changes the effective hourly rate for overtime, the wage statement must show the adjusted rate. If a retroactive bonus covers multiple pay periods, the statement should identify the relevant timeframe and any recalculated overtime. Employees who cannot determine their gross wages, net wages, deductions, or applicable rates from the statement alone are treated as “injured” under the statute and can pursue penalties.

Penalties That Stack

California layers several penalty schemes, and one underpaid bonus can trigger more than one at the same time.

Waiting Time Penalties

Under Labor Code Section 203, when an employer willfully fails to pay any wages owed at the end of employment, the penalty accrues at the employee’s daily wage rate for each day payment is late, up to 30 days. “Willful” does not require bad intent; it means the employer knew what it was doing and the failure was within its control.¹¹ An employee earning $200 per day could collect up to $6,000 in waiting time penalties on top of the unpaid bonus.

Wage Statement Penalties

Under Labor Code Section 226(e), an employee who suffers injury from a knowing and intentional wage statement violation can recover the greater of actual damages or $50 for the first violation and $100 for each subsequent violation, up to $4,000 per employee, plus attorney’s fees and costs.¹⁰ When bonus-related overtime adjustments are missing, every affected pay period is a separate violation.

PAGA Claims

The Private Attorneys General Act allows employees to sue on behalf of the state for labor code violations. After AB 2288’s 2024 overhaul, the default penalty is $100 per aggrieved employee per pay period.¹² The penalty drops to $50 for isolated, nonrecurring violations lasting no more than 30 consecutive days, and rises to $200 when a court or agency previously found the practice unlawful, or when the conduct was malicious or fraudulent.

Employers who were already taking all reasonable steps to comply before receiving a PAGA notice face a cap of 15% of the amount otherwise owed. Employers who begin taking reasonable compliance steps within 60 days of the notice face a cap of 30%.¹³

How Employees Can Recover an Unpaid Bonus

An employee who believes a bonus is owed should start with the employment contract, any bonus plan documents, and recent wage statements. Put the request to the employer in writing and keep a copy.

If direct resolution fails, the employee can file a wage claim with the California Division of Labor Standards Enforcement. There is no filing fee. The Labor Commissioner’s office investigates, typically schedules a settlement conference, and moves to a formal hearing if the parties cannot agree.¹⁴ A prevailing employee can be awarded the unpaid bonus, waiting time penalties, and interest.

Filing Deadlines

Statutes of limitations control how far back an employee can reach. Claims for unpaid overtime, illegal deductions, and minimum wage violations must be filed within three years. Claims based on an oral promise to pay more than minimum wage have a two-year deadline. Claims based on a written contract have four years. Missing these deadlines forfeits the right to recover, regardless of the merits.

Attorney’s Fees

Under Labor Code Section 218.5, a prevailing employee in a wage nonpayment action can recover reasonable attorney’s fees and costs. The provision is effectively one-way: if the employer prevails, it can only recover fees by showing the employee brought the claim in bad faith. That asymmetry makes it less risky for employees to pursue legitimate bonus disputes and more costly for employers to fight them.

For systemic violations affecting multiple employees, a class action or PAGA representative action may be appropriate and can produce company-wide penalties along with changes to bonus policies. Employers should treat even a single PAGA notice as a serious compliance event.
