Many California parents earn substantially more than their regular base salary.
A nurse may work additional shifts. A firefighter may receive significant overtime compensation. A salesperson may depend on commissions that fluctuate throughout the year. An executive may receive an annual performance bonus representing a substantial portion of total compensation.
When calculating child support, should the court include these earnings?
Generally, yes.
California Family Code section 4058 broadly defines gross income for child support purposes. Bonuses, commissions, and overtime ordinarily fall within that definition.
However, determining how these earnings should affect a monthly support obligation can be considerably more complicated.
Should the court average a salesperson’s commissions over twelve months? What happens when a parent receives an unusually large bonus that may never be paid again? Can a parent be required to continue working substantial overtime indefinitely because of an extraordinary work schedule maintained during the marriage?
California appellate courts have addressed these questions and established important distinctions between actual earnings, anticipated income, fluctuating compensation, and earning capacity.
In particular, the California Supreme Court’s decision in In re Marriage of Simpson (1992) 4 Cal.4th 225 limits the use of extraordinary historical work schedules when attributing earning capacity.
At Edgar & Dow, we examine compensation agreements, year-to-date earnings, historical income, and the circumstances affecting future compensation before preparing guideline child support calculations using Xspouse.
The software performs the mathematical calculation. Determining the appropriate income figures requires careful legal and factual analysis.
California Family Code section 4058(a) broadly defines annual gross income as income from whatever source derived, subject to statutory exceptions.
Section 4058(a)(1) expressly includes wages, salaries, commissions, and bonuses.
Overtime compensation also generally constitutes income because it represents additional wages earned through employment.
Consequently, compensation does not become irrelevant merely because it is paid irregularly or separately from ordinary wages.
Consider a hypothetical employee earning $110,000 annually in salary and receiving another $35,000 in commissions.
The additional commissions generally must be considered when determining the parent’s gross income.
However, identifying compensation as income is only the first step.
The court must determine the appropriate amount to include and whether historical compensation reasonably represents the parent’s actual or anticipated earnings.
This distinction becomes particularly important when compensation varies significantly.
Generally, yes.
In County of Placer v. Andrade (1997) 55 Cal.App.4th 1393, the Court of Appeal addressed the treatment of overtime and bonus compensation.
The court explained that predictable overtime ordinarily cannot be disregarded without evidence establishing that the earnings are unlikely to continue.
The parent had received substantial additional compensation over an extended period. The trial court excluded those earnings without an adequate evidentiary basis for concluding that they would not recur.
The Court of Appeal found that exclusion erroneous.
The decision illustrates an important principle.
A parent who consistently earns overtime cannot necessarily calculate child support using only regular wages by arguing that overtime is not contractually guaranteed.
Suppose a firefighter earns $105,000 annually in regular compensation and receives approximately $35,000 in overtime for several consecutive years.
If the overtime remains available and the earnings are reasonably predictable, the court ordinarily must consider that compensation.
But the analysis may change if overtime opportunities disappear or other circumstances make historical earnings an unreliable predictor of future income.
The question is what the evidence establishes about the parent’s actual and prospective earnings.
Historical overtime does not necessarily establish that equivalent compensation will continue indefinitely.
An employer may eliminate additional shifts, change staffing requirements, discontinue projects, or modify overtime policies.
Family Code section 4060 permits an adjustment when the calculated monthly net disposable income does not accurately reflect actual or prospective earnings.
For example, a hospital employee may have worked significant overtime during a temporary staffing shortage.
After the hospital hires additional employees, overtime opportunities may substantially decline.
Under those circumstances, the parent’s historical income may no longer accurately represent anticipated earnings.
However, the court needs evidence.
A parent’s unsupported statement that overtime is no longer available may be less persuasive than employer records confirming changes in staffing or scheduling.
Relevant documentation can include employer correspondence, revised work schedules, payroll histories, and compensation policies.
In Andrade, the court emphasized the need for evidence before excluding previously received overtime compensation.
A support calculation should not assume historical overtime will continue forever. But it should not disregard established earnings based solely on speculation that overtime may eventually disappear.
A voluntary reduction in overtime presents a different issue from an employer’s elimination of available work.
A parent may reduce additional shifts because of health concerns, childcare responsibilities, employment changes, or the desire to maintain a more reasonable work schedule.
Those circumstances may be legitimate.
Nevertheless, voluntarily reducing earnings does not automatically require the court to calculate support using the reduced amount.
California courts distinguish between actual income and earning capacity.
Actual income concerns the compensation a parent receives.
Earning capacity concerns the income that may appropriately be attributed based on the parent’s ability and opportunity to earn, subject to the statutory requirements.
The distinction is especially important when a parent previously worked unusually long hours.
That issue was addressed by the California Supreme Court in In re Marriage of Simpson.
In In re Marriage of Simpson (1992) 4 Cal.4th 225, the California Supreme Court considered whether a support obligation could be based on earnings generated through an extraordinarily demanding work schedule.
The father worked as a theatrical stagehand in theaters and television studios.
During the marriage, he frequently worked multiple jobs, including nights and weekends, and sometimes worked as many as sixteen hours in a day.
After separation, he voluntarily moved toward lower-paying employment with a more conventional schedule.
The trial court concluded that he had reduced his earnings primarily to avoid family support obligations.
The Supreme Court recognized that the trial court could properly consider earning capacity under those circumstances.
However, the trial court had attributed approximately $60,000 in annual earning capacity based on the father’s prior extraordinary earnings without adequately establishing that he could earn that amount through a reasonable work schedule.
The Supreme Court found that determination improper.
The distinction is critical.
A parent cannot automatically avoid support obligations by voluntarily moving to lower-paying work.
But a court also should not automatically require a parent to maintain excessive overtime or an extraordinary work regimen indefinitely.
The court must determine what the parent can reasonably earn based on an objectively reasonable work regimen at the time support is calculated.
No.
The California Supreme Court did not establish a universal forty-hour workweek limitation.
What constitutes a reasonable work schedule depends on the circumstances.
The court may consider the nature of the occupation, available employment, working conditions, customary hours, and other relevant factors.
Some occupations ordinarily require more than forty hours of work or occasional overtime.
For example, the normal schedule of a firefighter may differ significantly from that of an employee in a conventional office position.
Likewise, a healthcare professional may routinely work extended shifts.
The relevant question is whether the proposed work regimen is objectively reasonable, not simply whether it exceeds forty hours per week.
In Simpson, the Supreme Court recognized that an extraordinary schedule involving substantial continuous overtime should not automatically determine earning capacity.
The decision remains particularly important when a parent voluntarily reduces overtime.
It protects against attributing income based on an excessively demanding historical schedule while preserving the court’s ability to consider appropriate earning capacity.
The two decisions address related but distinct issues.
County of Placer v. Andrade concerns predictable overtime that forms part of a parent’s actual income.
In re Marriage of Simpson concerns the proper measurement of earning capacity when the court considers attributing income based on work the parent is no longer performing.
Suppose a nurse consistently earns substantial overtime and continues accepting additional shifts.
Under Andrade, those earnings ordinarily belong in the income analysis when they are reasonably predictable.
Now suppose the nurse reduces overtime to a more sustainable schedule.
If the court considers attributing additional earnings based on the nurse’s capacity to work overtime, Simpson requires consideration of whether the proposed schedule is objectively reasonable.
The fact that a parent once worked extraordinarily long hours does not necessarily establish that those hours must continue.
These decisions should be read together rather than treated as contradictory.
Generally, bonuses qualify as income under Family Code section 4058(a)(1).
However, determining how an annual bonus affects monthly child support requires examining its nature.
Suppose a parent earns $150,000 in annual salary and receives a $75,000 performance bonus.
That bonus substantially increases total compensation.
But the fact that a bonus was received does not automatically establish that an equivalent payment will be received every year.
Some bonuses are governed by employment contracts or established compensation formulas.
Others depend on individual performance, company profitability, discretionary employer decisions, or changing economic conditions.
A parent who consistently receives approximately the same bonus each year may present a different situation from an employee who received an exceptional payment under unusual circumstances.
The appropriate analysis requires examining the available evidence and determining whether past bonus income reasonably predicts future earnings.
One of the most important decisions concerning uncertain bonus compensation is In re Marriage of Mosley (2008) 165 Cal.App.4th 1375.
The father received a substantial base salary and had received a discretionary bonus.
The trial court established combined child and spousal support obligations of approximately $10,000 per month.
His regular monthly take-home salary was approximately $11,000.
The resulting order left him with very little money for ordinary living expenses during months when no bonus was received.
The Court of Appeal concluded that the order improperly depended on anticipated discretionary compensation without adequately considering the father’s ongoing financial circumstances.
The decision recognizes the practical problem of treating a potentially uncertain year-end bonus as though the money is continuously available throughout the year.
A parent should not automatically be required to finance living expenses by borrowing against a future bonus that may never materialize.
However, Mosley does not establish that discretionary bonuses are excluded from child support.
Bonuses actually received remain relevant income.
The question is how to account for those earnings in a manner consistent with the statutory support framework and the evidence.
Yes, depending on the evidence.
In M.S. v. O.S. (2009) 176 Cal.App.4th 548, the Court of Appeal considered recurring semiannual payments received through an Indian tribe’s gaming revenues.
The court determined that the payments properly formed part of the parent’s income under the circumstances presented.
The record did not establish that the recurring payments were likely to stop.
The court also distinguished the circumstances from those in Mosley.
These decisions illustrate why compensation paid less frequently than monthly is not automatically excluded.
A parent receiving predictable semiannual compensation may reasonably be expected to account for those earnings throughout the year.
A parent whose bonus depends on uncertain discretionary decisions may present different circumstances.
The inquiry concerns recurrence, predictability, and the evidence supporting anticipated future earnings.
Commission-based employment frequently produces substantial monthly fluctuations.
A real estate professional may receive a substantial commission following a completed transaction and little income in another month.
A salesperson may earn more during peak seasonal periods.
Another employee may receive commissions only after major contracts close.
Using a single month’s earnings can produce a misleading result.
In In re Marriage of Riddle (2005) 125 Cal.App.4th 1075, the Court of Appeal addressed income averaging for a commissioned salesperson.
The trial court relied on a two-month earnings period.
The Court of Appeal concluded that the sample was insufficiently representative of the employee’s income.
The court explained that an income average should be based on a fair and representative period reasonably predictive of prospective earnings.
The goal is to determine an appropriate income figure rather than select an unusually favorable or unfavorable month.
Twelve months is an important benchmark, but not an absolute rule.
In In re Marriage of Riddle, the Court of Appeal recognized that California’s child support statutes emphasize annual income.
As a result, the most recent twelve months will often provide an appropriate starting point for averaging fluctuating compensation.
However, the averaging period must reasonably represent the parent’s likely prospective earnings.
A longer period may be useful when income varies substantially from year to year.
For example, an employee receiving commissions through a business cycle may experience exceptional earnings one year and significantly lower earnings the next.
Conversely, historical income from an outdated compensation arrangement may not accurately reflect current earning opportunities.
A period that is too short may also distort the calculation.
In Riddle, the two-month sample did not provide a reliable basis for determining annual income.
The appropriate period depends on the nature of the employment, available financial history, and circumstances affecting anticipated earnings.
The objective is not simply to average numbers.
It is to select a representative period that reasonably predicts income available for support.
In In re Marriage of Pletcher (2021) 68 Cal.App.5th 906, the Court of Appeal addressed the problem of using a single unusually profitable year when calculating support for a parent with substantially fluctuating income.
The court determined that the selected period did not adequately account for the volatility of the parent’s earnings.
The decision discussed potential approaches that could more accurately address the income fluctuations.
One approach involved expanding the financial history to include additional years.
Another involved consideration of an appropriate percentage-based component addressing variable earnings.
Pletcher reinforces the principle established in Riddle: The income sample must reasonably represent the financial circumstances.
The court should not automatically use a single exceptional year simply because it produces a readily available annual figure.
When compensation fluctuates substantially, a broader analysis may be required.
Family Code section 4064 permits courts to adjust child support orders to accommodate seasonal or fluctuating income.
This flexibility may be important for employees receiving commissions, bonuses, or other irregular compensation.
For example, a salesperson may earn relatively little during slower months and substantially more during peak periods.
An appropriately structured support order may account for those variations without requiring frequent modification proceedings.
However, the statewide guideline formula requires specific income figures.
An arrangement addressing future variable compensation is not necessarily the same as the guideline calculation itself.
This distinction becomes especially important when an order requires an additional percentage of future bonuses or commissions.
The statutory requirements governing such an order must be considered.
An Ostler-Smith provision generally refers to a support arrangement addressing additional compensation through a percentage-based payment mechanism.
The term originates from In re Marriage of Ostler & Smith (1990) 223 Cal.App.3d 33.
Such provisions may be considered when future compensation cannot be predicted accurately at the time support is determined.
For example, the court may establish regular support based on a parent’s reasonably anticipated recurring income while separately addressing qualifying future bonuses.
However, the use of a percentage provision does not automatically make the resulting arrangement the statutory guideline amount.
The actual order must comply with California’s child support statutes.
Potentially, yes.
However, In re Marriage of Hall (2000) 81 Cal.App.4th 313 establishes an important limitation.
In Hall, the order required additional child support based on a percentage of earnings exceeding a specified amount.
The Court of Appeal concluded that the percentage provision could not simply be characterized as guideline support without satisfying the applicable statutory requirements.
Under the framework discussed in Hall, a percentage-based departure from guideline support requires an appropriate legal basis, such as a qualifying stipulation or the mandatory findings required for a guideline deviation.
Family Code sections 4056 and 4057 address the relevant statutory findings and circumstances.
The decision illustrates why percentage provisions should not be adopted merely because they appear convenient.
The court must first determine the appropriate guideline amount and then establish a legally supportable basis for any different arrangement.
The discussion in Pletcher further demonstrates that a percentage-based mechanism may be considered when conventional averaging does not adequately address substantial income volatility.
Nevertheless, the proposed arrangement must be consistent with the governing statutes.
Percentage-based support provisions can create disputes if their terms are unclear.
For example, an order should appropriately address the income to which the percentage applies.
Does the provision cover bonuses, commissions, or both?
Are the amounts measured before or after particular taxes?
When must the additional support be calculated and paid?
What happens if an employer changes its compensation structure?
Another important consideration is double counting.
If predictable bonus income has already been included when establishing base guideline support, a separate percentage provision should not automatically treat those same earnings as additional income again.
The financial analysis must identify which compensation is already reflected in the base calculation.
The objective is to establish an understandable and legally supportable order that appropriately addresses future compensation.
Year-to-date earnings provide an important starting point when evaluating variable compensation.
Pay statements may separately identify regular wages, overtime, commissions, bonuses, and other payments.
However, the reporting period must be understood.
A year-to-date statement covering nine months does not necessarily represent annual compensation.
Likewise, projecting nine months of earnings over twelve months may be misleading when substantial bonuses are paid at year-end or commissions fluctuate seasonally.
The attorney should compare current earnings with relevant historical compensation.
Prior-year W-2 forms, tax returns, compensation agreements, and employer records may help establish whether earnings are recurring or exceptional.
The purpose is to identify a reasonable figure supported by the evidence.
A parent seeking to exclude historical overtime or bonus compensation should be prepared to present reliable evidence establishing why the income is unlikely to recur.
In County of Placer v. Andrade, the court rejected the exclusion of historical compensation where the record lacked adequate evidence that the earnings would cease.
An employee’s unsupported prediction may not be sufficient.
Relevant records can include employer statements, revised compensation policies, changes in job duties, eliminated overtime opportunities, or documentation concerning the termination of a bonus program.
For commission-based employment, changes in sales territory, customer accounts, compensation percentages, and employment conditions may also be relevant.
The goal is to demonstrate why historical earnings no longer reasonably represent anticipated compensation.
A material change in compensation may support a request to modify an existing child support order, depending on the circumstances and applicable legal requirements.
For example, an employee may lose access to substantial overtime opportunities.
A salesperson may experience a significant change in compensation structure.
An executive may lose eligibility for a recurring bonus program.
Conversely, a parent may begin receiving substantially greater variable compensation.
These circumstances may change the financial information relevant to guideline support.
However, an existing order does not automatically change when income increases or decreases.
A parent should seek advice concerning whether a modification is appropriate and the procedural steps necessary to pursue it.
California guideline support software calculates support using the information supplied.
But the software cannot independently determine whether a bonus will recur, whether a commission average is representative, or whether historical overtime reflects an objectively reasonable work schedule.
Those are legal and factual questions.
At Edgar & Dow, we examine compensation histories, employer records, financial disclosures, and applicable California law before preparing guideline support calculations using Xspouse.
An inaccurate income figure can significantly affect the support obligation.
The goal is to determine income accurately rather than rely on assumptions drawn from a single paycheck or an unusually profitable year.
Generally, yes. Predictable overtime ordinarily constitutes income under Family Code section 4058, subject to appropriate consideration of evidence concerning future earnings.
Not automatically. In re Marriage of Simpson requires earning capacity to be measured according to an objectively reasonable work regimen rather than an extraordinary historical schedule.
No. Reasonable working hours depend on the occupation, employment conditions, and other relevant circumstances.
Generally, yes. However, the appropriate treatment depends on whether the compensation is recurring, predictable, discretionary, or unlikely to continue.
The court may consider reliable evidence concerning the uncertainty and appropriate treatment of the bonus. In re Marriage of Mosley provides important guidance.
Yes. Commissions generally qualify as income, although fluctuating compensation may require averaging over a representative period.
No. Twelve months is an important benchmark, but the court must select a period that reasonably reflects prospective earnings.
It is a commonly used term for an arrangement addressing future variable compensation through a percentage-based support provision. Such arrangements must comply with the applicable statutory requirements.
Potentially, yes. However, In re Marriage of Hall requires an appropriate statutory basis for a percentage provision that departs from guideline support.
A material change in compensation may justify seeking modification, depending on the circumstances. The existing order does not automatically change.
Bonuses, overtime, and commissions often represent a significant portion of a parent’s financial resources.
California law generally requires these earnings to be considered when determining child support.
However, the appropriate analysis involves more than adding historical compensation together.
The court may need to determine whether earnings are likely to recur, whether the averaging period is representative, and whether future variable income should be addressed through an appropriately structured support order.
In re Marriage of Simpson adds an important limitation concerning the use of extraordinary historical work schedules when attributing earning capacity.
The decisions in Andrade, Riddle, Mosley, Pletcher, and Hall further illustrate the importance of careful financial analysis and compliance with the statutory framework.
An accurate child support calculation requires consideration of both the evidence and the applicable California law.
If your income includes overtime, commissions, performance bonuses, or other fluctuating compensation, the financial analysis can materially affect your child support obligation.
