Short answer: California support decisions look at income and earning capacity available for support, not merely the amount an owner labels as a paycheck. A court may examine salary, draws, distributions, benefits, business-paid personal expenses, retained earnings, commissions, and the owner’s ability to earn. But business revenue is not automatically personal income, and a support calculation should not count the same dollars twice. The analysis requires reliable records and a clear explanation of what money is actually available.

Why a paycheck may not tell the whole story

An owner can receive compensation through payroll, draws, distributions, reimbursements, use of a company vehicle, housing, or payment of personal expenses. A professional may control when income is received, defer a bonus, retain cash, or change the mix of salary and distributions. A commissioned employee may have irregular checks despite a predictable annual pattern. These facts can make a single pay stub misleading.

That does not mean every business expense should be added back. A business needs legitimate costs to operate, pay employees, maintain inventory, and meet debt obligations. The useful question is whether an expense is ordinary and necessary, personal, discretionary, or a compensation substitute. Review several years, not just the month before a hearing, and account for seasonal variation.

Records a support analysis usually needs

Gather tax returns, W-2s or 1099s, pay stubs, payroll registers, profit-and-loss statements, balance sheets, general ledgers, bank statements, credit-card statements, loan applications, distributions, shareholder or partnership records, and records of benefits paid by the business. Include calendars or contracts showing commissions, bonuses, shifts, and expected work. Preserve a written explanation for unusual changes.

Compare the business return with the owner’s personal return and the financial disclosure. Look for business-paid expenses, shareholder loans, related-party payments, cash withdrawals, unusual travel, changes in inventory, and retained earnings. A discrepancy is a question for follow-up, not automatic proof of concealment. Lawful discovery may include targeted document requests, subpoenas, or a deposition.

What is earning capacity?

Earning capacity is an argument that a person could earn more than current reported income based on ability, opportunity, and willingness to work. A court does not simply assume that every professional should work maximum hours or that every business can produce its best year. Evidence might include health, skills, licensing, work history, available employment, business opportunities, child-care responsibilities, market conditions, and the reason income changed.

A voluntary reduction in work can raise different questions from a layoff, illness, business downturn, caregiving decision, or genuine loss of customers. The timing matters: a reduction after separation or a support request may prompt scrutiny, but timing alone is not proof of bad faith. The party asking the court to use earning capacity must present evidence, and the other party should be able to explain why the proposed income is unrealistic.

Retained earnings and business cash

Retained earnings are not automatically available for personal support. The analysis may consider whether cash is needed for payroll, taxes, inventory, debt, reserves, or a documented business purpose. It may also consider whether the owner controls distributions, has accumulated cash without a credible need, or uses the company to pay personal expenses. A balance-sheet number is not the same as spendable monthly income.

Separate two questions: the value of an ownership interest for property division and the cash flow available for support. Using the same retained earnings as both a property asset and monthly income can create double counting. Conversely, ignoring accessible business cash can understate available resources. A qualified accountant can explain the accounting; counsel should connect that explanation to the legal support standard.

Child and spousal support are not identical

Child support uses statewide guideline inputs and may involve timeshare, mandatory add-ons, and the children’s needs. Spousal support involves additional statutory factors and, in many settings, judicial discretion. A software estimate can help identify inputs, but it is not a ruling. Accurate gross income, tax assumptions, health insurance, child-care, and parenting time matter.

For spousal support, the court may examine the marital standard of living, each party’s earning ability, assets, needs, obligations, duration of marriage, and other statutory considerations. A person who owns a business should not assume that a low salary eliminates support exposure; a supported spouse should not assume that gross receipts equal available income.

Handling disagreement over the numbers

Create an income schedule showing each source, period, gross amount, taxes, business expenses, distributions, and proposed adjustment. Identify which figures are verified and which are estimates. Explain one-time events separately from recurring income. If a business is closely held, request records that can be authenticated and protect confidential customer or patient information.

Do not hide cash, transfer ownership, alter books, stop working solely to affect support, or use company accounts for personal litigation without advice. Such conduct can create evidentiary, fiduciary, tax, or sanctions issues. Review financial disclosure and discovery and keep a dated record of production.

Practical preparation checklist

Gather at least several years of personal and business income records.
List salary, draws, distributions, benefits, reimbursements, and business-paid personal costs.
Explain seasonality, unusual expenses, loans, losses, and changes in work.
Separate property value from support cash flow.
Document health, child-care, market, licensing, and opportunity facts relevant to earning capacity.
Use current guideline inputs and verify forms, deadlines, and local procedure.
Obtain accounting, tax, or vocational evidence when the numbers cannot be explained from ordinary records.

The strongest support presentation is transparent about both strengths and limitations. It gives the court a usable picture of actual resources without treating revenue, assets, or an optimistic projection as the same thing as available income.

Explain a change in income with evidence

If income declined, identify when it changed, what caused the change, and what steps were taken. A medical limitation may require medical evidence; a business downturn may require contracts, sales records, industry information, or financial statements; a caregiving decision may require a parenting and work schedule. If income increased, identify whether the increase is recurring, seasonal, or a one-time payment. The goal is not to present the most favorable month, but a credible picture over time.

If the other spouse controls the business, request records through counsel rather than relying on informal access. If both spouses work in the business, keep personal conflict out of bookkeeping and preserve ordinary operations. Never alter a ledger to make income appear lower or higher. Accurate records allow the court to evaluate capacity while reducing the risk that a legitimate fluctuation will be treated as intentional concealment.

The same records may also reveal whether a claimed loss is temporary or likely to continue. Present the explanation consistently in disclosures, discovery responses, declarations, and any proposed guideline calculation.

When records are incomplete, identify the limitation rather than presenting a precise but unsupported figure. That candor helps distinguish a disputed input from an intentional omission.
