California Child Support Guide / Income and earning capacity

Rental and investment income can affect California child support even when it is not received through a paycheck. The analysis distinguishes income from the underlying asset, examines legitimate expenses, and avoids counting the same money twice. A tax return is an important starting point, but it does not answer every support question.

Family Code section 4058 broadly addresses income from sources including rents, interest, dividends, and business activity. The practical task is to identify what the parent actually receives or has available and how it should be treated under the support rules.

Rental receipts are not the final income figure

Start with rent collected and supporting leases, deposit records, and property-management statements. Distinguish rent from refundable security deposits, transfers, borrowing, and owner contributions.

Then examine expenses. Property taxes, insurance, management costs, repairs, financing charges, and other claimed items must be supported and legally evaluated. A payment reducing loan principal is not automatically the same as an operating expense. Tax depreciation is not an allowable deduction from rental income for guideline child support.

For a short-term rental, compare platform statements with bank deposits, cancellations, fees, and operating records. Gross booking revenue and the amount deposited after platform deductions are different figures.

Why rental depreciation is added back

In Asfaw v. Woldberhan (2007) 147 Cal.App.4th 1407, 1425–1426, the court held that depreciation of rental property is not deductible in determining child support income. A tax return can therefore show a loss while the support calculation shows available rental income. The tax treatment and the support treatment serve different purposes.

Prepare a schedule that starts with rental receipts and separately identifies actual expenses, depreciation, loan principal, and capital expenditures. Adding back depreciation does not mean every cash payment becomes deductible. A roof replacement, for example, must be analyzed as a capital expenditure rather than automatically treated as an ordinary monthly repair. Supply the records so the court can evaluate each adjustment.

Use a representative period

One profitable month may not describe an entire rental year. Vacancy, seasonal demand, repairs, and unusual expenses can distort a short sample.

Provide enough history to explain the property’s normal operation and any material change. Identify an extraordinary repair separately from recurring maintenance. If the property was recently acquired, explain which figures are actual and which are projected.

The court needs a supported estimate of relevant income, not whichever month produces the preferred support result.

Investment income and account transfers

Interest and dividends should be traced to account statements and tax reporting. Moving money between brokerage accounts does not itself create new income.

A withdrawal can include earnings, invested principal, or both. A sale can produce proceeds much larger than the gain. Review the acquisition cost, sale documents, transaction history, and tax information before treating the entire deposit as income.

Likewise, unrealized appreciation and employment-related equity compensation raise different legal questions. Do not assume every increase in an account balance is current earnings.

Ownership through a business or trust

A parent may receive rental or investment returns through an entity. Examine ownership, distributions, retained funds, control, and the underlying records.

A schedule K-1, distribution, and bank deposit may describe overlapping aspects of the same economic activity. They should be reconciled rather than simply added together.

If the parent controls the entity, personal expenses paid through it may also matter. Identify the benefit and avoid counting it again if it is already included in the proposed income figure.

Asset value and earning capacity are separate issues

Owning a valuable asset does not mean its full value becomes monthly support income. However, investment choices and available resources can raise questions about earning capacity or an appropriate guideline departure.

Those issues require evidence and the applicable legal findings. A parent should not assign an arbitrary rate of return to the other parent’s property without explaining the legal basis and factual assumptions.

Records that make the issue understandable

Collect leases, rent rolls, management statements, bank records, mortgage statements, expense invoices, tax returns, brokerage statements, and entity records. Prepare a reconciliation showing receipts, claimed deductions, adjustments, and the resulting proposed figure.

For example, explain why a large deposit represents loan proceeds rather than rent, or why a tax deduction does not reflect a current cash expense. Specific explanations are more persuasive than broad claims that a property “loses money.”

Common questions

Does rental income count if the property is separate property?

Separate-property characterization does not automatically exclude income from child support analysis.

Can I deduct every expense shown on my tax return?

Not automatically. Support treatment requires its own analysis.

Is the whole sale price income?

Do not equate proceeds with gain or recurring income without examining the transaction.
