Child Support and Bonuses: When Extra Income Must Be Shared

California Child Support Recovery System | Justice Foundation

Annual bonuses, commissions, stock option exercises, and other variable compensation are income for child support purposes in California — and they are often the most significant income events in a paying parent’s year. Ensuring that this variable income is properly accounted for in the support calculation and collected when it arrives requires specific strategies that most custodial parents don’t employ.

Variable Income in the Guideline Calculation

California’s guideline formula uses net disposable income from all sources. For employees with variable compensation — sales commissions, annual bonuses, stock-based compensation — courts typically average variable income over the relevant period to determine monthly income for support purposes. A salesperson who earned $80,000 in base salary plus $60,000 in commissions last year has average monthly income of $11,667 — the commission income is included, not ignored.

If the paying parent’s support obligation was set based on base salary only and their variable compensation is substantial, a modification may be warranted to include average variable income in the calculation.

Bonus Orders: Percentage Shares of Variable Income

California courts can order a paying parent to pay a percentage of bonuses, commissions, and other non-regular income directly to the custodial parent when received. This is sometimes called a “bonus order” or a provision addressing variable income. The percentage is calculated to bring total annual support closer to what the guideline would require if variable income were fully included. If your support order doesn’t have a bonus provision and the paying parent receives significant variable compensation, request one at your next hearing.

Monitoring and Collecting Variable Income

Variable income is easily concealed — a bonus paid to a different account, stock options exercised and transferred, commissions delayed to a period when support is no longer being actively monitored. DCSS’s income withholding process captures regular wages but often misses variable compensation. Independent enforcement through periodic debtor examinations and tax return review is the most reliable way to capture variable income. The Justice Foundation kit includes bonus order request language and monitoring procedures for variable compensation.
