A self-employed parent may report substantial depreciation deductions on a tax return even though those deductions do not represent money actually paid during the year. When calculating California child support, the court may add depreciation back to business income to obtain a more accurate picture of the parent’s available cash flow.

Tax Deductions Do Not Control Support Income

Business income for child support generally consists of gross receipts reduced by expenditures reasonably required to operate the business. Federal and state tax rules may allow deductions that do not qualify as required business expenditures for support purposes.

Depreciation is a common example. It spreads an asset’s cost over multiple tax years rather than reflecting a current cash payment. A tax return showing reduced taxable income therefore may understate the money available to support a child.

Depreciation on Different Business Assets May Be Disallowed

California courts have disallowed depreciation deductions involving rental property, business vehicles, equipment, and other assets used in a self-employed parent’s operations. The reasoning is that depreciation is generally an accounting allowance rather than an actual outlay of cash.

The amount may be added back to the income reported on the tax return when calculating support. This does not mean the court must ignore the real cost of operating or preserving business assets, however.

Actual Capital Expenditures Still Require Review

A business may have made genuine cash expenditures to purchase, repair, or replace equipment. Those payments should be distinguished from the depreciation deduction itself.

The court may examine whether an expenditure was necessary, when it was paid, how it was financed, and whether it provided a personal benefit. An equipment purchase funded through a loan presents different cash-flow issues from a purchase paid entirely during the support period.

Accelerated depreciation and unusually large one-time deductions may require particular scrutiny. Using several years of records can help separate normal operations from accounting choices that produce an unrepresentative result.

Complete Business Records Are Important

Relevant evidence may include business tax returns, depreciation schedules, purchase invoices, loan documents, general ledgers, bank statements, and records showing capital expenditures. A self-employed parent who controls the records should be prepared to explain each claimed deduction.

A California child support attorney working with a financial professional can distinguish tax depreciation from necessary cash expenses and calculate income based on economic reality. Until the court modifies an existing support order, that order remains binding even if the parent believes taxable income has declined.
