California Bonus Pay Laws: Overtime, Clawbacks, and Penalties

California bonus pay laws treat most bonuses as wages, which means they carry the same protections as regular paychecks: they must factor into overtime calculations, be paid on time, appear accurately on wage statements, and be included in final pay when employment ends. A new law effective January 1, 2026 also limits how employers can structure sign-on bonus repayment clauses. Getting any of this wrong exposes employers to penalties that stack quickly.

Discretionary vs. Non-Discretionary Bonuses

Almost every legal question about a bonus in California begins with this classification. It decides whether the bonus counts as wages, whether it has to be included in overtime pay, and whether late payment triggers wage penalties.

Non-Discretionary Bonuses Are Wages

A non-discretionary bonus is tied to measurable criteria the employee can point to and claim: a sales target, an attendance threshold, a production quota, a profitability number, or staying employed through a certain date. The Division of Labor Standards Enforcement treats these as earned compensation that must be included in the regular rate of pay for overtime purposes.¹

Once criteria are set and the employee meets them, the bonus is owed. In Marin v. Costco Wholesale Corp. (2008), a California appellate court affirmed that overtime on production-based bonuses must be computed and paid under the pay-period rules of Labor Code Section 204.² Delaying or withholding earned bonuses can trigger waiting time penalties under Labor Code Section 203, equal to the employee’s daily wage for up to 30 days.³

Truly Discretionary Bonuses

A discretionary bonus is one the employer awards without any prior promise or formula. Holiday gifts and spontaneous rewards are the classic examples. Because the employee has no way to earn it through specific performance, it is not treated as wages and does not get folded into overtime.¹

The line is thinner than it looks. If a company pays a year-end bonus every December and employees come to expect it, a court may find an implied obligation. The safer practice is to document each discretionary bonus in writing at the time of payment, stating that it was not promised, not based on any formula, and creates no expectation of future payments.

Incentive and Commission Bonuses

Incentive bonuses tied to sales targets, retention milestones, or similar goals are a subset of non-discretionary bonuses and must be included in overtime calculations.¹ Labor Code Section 2751 requires written contracts for commission pay, but it excludes most bonuses from that rule. Short-term productivity bonuses, variable incentive payments that only increase compensation, and profit-sharing plans are not commissions under Section 2751.⁴ A written agreement is still smart practice regardless, because vague bonus terms almost always get resolved in the employee’s favor.

How Bonuses Change Overtime Pay

Every non-discretionary bonus must be built into the regular rate of pay used for overtime, and the formula 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 non-overtime hours worked during the bonus-earning period, not total hours. That per-hour value is then multiplied by 1.5 (or 2.0 for double-time hours) and applied to every overtime hour.¹

A worked example: an employee earns a $30 flat-sum bonus in a week with 40 regular hours and 8 overtime hours. Divide $30 by 40 to get $0.75 per hour. Multiply by 1.5 to get $1.125. Multiply by 8 overtime hours. The employee is owed an extra $9.00 in overtime attributable to the bonus. Using 48 total hours as the divisor would underpay the employee and violate California law.

Production Bonuses

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

Percentage-Based Bonuses

A bonus calculated as a percentage of total earnings already scales with hours worked, which simplifies the adjustment. The bonus amount still has to be included in total compensation when recalculating the overtime rate, but the adjustment is smaller than for flat-sum or production bonuses.

When Bonuses Must Be Paid

Earned bonuses are wages, and California wage-payment deadlines apply. Under Labor Code Section 204, wages earned between the 1st and 15th of a month must be paid by the 26th, and wages earned between the 16th and the end of the month must be paid by the 10th of the following month. For weekly, biweekly, or similar schedules, payment is due within seven calendar days after the end of the payroll period.⁵

Bonuses tied to a single pay period follow that same schedule. Bonuses calculated over quarterly or annual periods must be paid as soon as the amount becomes calculable. Delay after the numbers are known creates the same liability as missing a regular payday.

Bonuses in Final Paychecks

When an employee is discharged, all earned wages, including any calculable bonus, are due immediately under Labor Code Section 201.⁶ When an employee resigns, final wages are due within 72 hours under Labor Code Section 202. If the employee gave at least 72 hours of advance notice, final wages are due on the last day of work.⁷

The harder case is a mid-period departure. If the written bonus terms allow proration and the employee met the relevant standards, a prorated share may be owed as earned wages. Clear written bonus plans decide these disputes; vague language rarely favors the employer.

Sign-On Bonus Clawback Rules in 2026

Effective January 1, 2026, AB 692 restricts “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, all of the following must be true:

The repayment terms are in a standalone document, not buried in the main employment contract.
The employee is told they have the right to consult an attorney and is given at least five business days to do so before signing.
Any repayment obligation does not accrue interest and is prorated based on the remaining retention period, which cannot exceed two years from receipt of the payment.
The employee has 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.

Mid-employment retention bonuses with clawback provisions are not covered by this exemption, making them considerably riskier for employers to enforce. Any sign-on or retention bonus with repayment terms should be reviewed against these conditions before new offers go out in 2026.

Tax Withholding on Bonus Payments

Bonuses are supplemental wages for tax purposes, and both federal and California rules set specific withholding treatment.

Federal Withholding

When a bonus is paid separately from regular wages and the employee’s supplemental wages stay under $1 million for the calendar year, the employer may either withhold federal income tax at a flat 22% or use the aggregate method, combining the bonus with the regular paycheck and withholding as if it were one payment. Supplemental wages above $1 million in a calendar year are subject to a mandatory 37% withholding rate on the excess.⁸

Social Security tax applies to bonus payments 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.⁹

California State Withholding

California sets its own supplemental wage rates through the Employment Development Department. Bonuses and stock option payments use a flat 10.23% state withholding rate; other supplemental wages use 6.6%.¹⁰ These rates apply regardless of the federal method chosen.

Wage Statement Requirements

Every California employer must provide itemized wage statements under Labor Code Section 226(a). The statement must include nine categories: gross wages, total hours worked, piece-rate details if applicable, all deductions, net wages, pay period dates, the employee’s name and last four digits of the 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 corresponding hours at each rate.¹¹

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

Penalties for Getting Bonuses Wrong

California penalty schemes stack. One underpaid bonus can trigger liability under several statutes at once.

Waiting Time Penalties

Under Labor Code Section 203, when an employer willfully fails to pay wages owed at the end of employment, the penalty accrues at the employee’s daily wage for each late day, up to 30 days. “Willful” does not require bad intent; it means the failure was within the employer’s control.³ An employee earning $200 a day could collect up to $6,000 in waiting time penalties on top of the unpaid bonus itself.

Wage Statement Penalties

Under Labor Code Section 226(e), an employee injured by a knowing and intentional wage statement violation can recover the greater of actual damages or $50 for the first violation and $100 for each later violation, up to $4,000 per employee, plus attorney’s fees and costs.¹¹ When bonus-related overtime adjustments are missing, every affected pay period counts as a separate violation.

PAGA Claims

Under the Private Attorneys General Act, employees can sue on behalf of the state for labor code violations. After the 2024 overhaul in AB 2288, the default PAGA penalty is $100 per aggrieved employee per pay period. It drops to $50 for isolated, nonrecurring violations lasting no more than 30 consecutive days, and rises to $200 when the employer was previously told by a court or agency that its practice was unlawful, or when the conduct was malicious or fraudulent.¹² Employers who were already taking all reasonable compliance steps before a PAGA notice can cap recoverable penalties at 15% of the amount otherwise owed; employers who begin reasonable compliance steps within 60 days of the notice face a 30% cap.¹³

How Employees Can Pursue an Unpaid Bonus

Start with the paperwork. Review the employment contract, any bonus plan documents, and wage statements. If a bonus that appears to have been earned has not been paid, request it in writing and keep a copy.

If that fails, 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 holds 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

Deadlines decide how far back a claim can reach. Unpaid overtime, illegal deductions, and minimum wage claims must be filed within three years. Claims based on an oral promise to pay more than minimum wage carry a two-year deadline. Claims based on a written contract have four years. Miss the deadline and the right to recover is gone, no matter how strong the underlying claim.

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 runs effectively one-way: a prevailing employer can only recover fees by showing the employee brought the claim in bad faith. That asymmetry makes legitimate bonus disputes less risky for employees to pursue and more expensive for employers to fight.

For systemic problems affecting multiple employees, a class action or PAGA representative action may be the right vehicle. These claims can produce company-wide penalties and force policy changes across an organization.
