How Self-Employment Income Is Calculated for Child Support
Self-employed parents face additional scrutiny in child support proceedings because their income is often less transparent than W-2 employment. Courts look beyond Schedule C net income to determine a parent's true earning capacity.
What Courts Add Back to Schedule C Income
Courts frequently add back deductions that reduce taxable income but do not represent actual cash expenses that reduce the parent's living standard:
- Depreciation: Non-cash deduction courts often add back entirely
- Vehicle personal use: Portion of business vehicle used personally
- Meals and entertainment: 50-100% may be added back
- Home office deduction: Often partially added back
- Excessive owner compensation: If unreasonably low compared to market
- Business perks paid as expenses: Travel, club memberships, etc.
Self-Employment Tax Treatment
Self-employed individuals pay both the employee and employer portions of FICA (15.3% total). Courts generally allow the deduction of the employer-equivalent portion (7.65%) from self-employment income, mirroring how W-2 employees' income is treated.
Add-backs = Depreciation + Personal Vehicle Use + 50% Meals + Home Office
Court Income = Schedule C Net + Add-backs
SE Tax Deduction = (Gross Revenue × 7.65%) ÷ 2
Adjusted Income = Court Income − SE Tax Deduction
