Every parent in Virginia has a legal obligation to support their children. The Commonwealth uses statutory guidelines to calculate the presumptive amount of support, but the calculation is more nuanced than running numbers through a formula. Income definitions, custody-time adjustments, healthcare allocations, and deviation requests all materially affect the actual amount ordered.
Randall J. Borden has handled child-support matters for Northern Virginia families for more than thirty years. The practice represents both obligors and recipients in Fairfax, Loudoun, Prince William, Arlington, and Alexandria — for initial support orders, enforcement, and modifications.
How Child Support Is Calculated in Virginia
Virginia uses the “income-shares” model. The basic calculation combines both parents’ gross monthly incomes, looks up the basic obligation in the statutory schedule based on combined income and number of children, then prorates that obligation between the parents based on each parent’s share of combined income.
Inputs to the Calculation
- Gross monthly income for each parent — salary, bonuses, commissions, self-employment income, rental income, investment income, military pay including BAH, and certain government benefits;
- Number of children covered by the order;
- Health-insurance premium paid for the children;
- Work-related childcare costs;
- Custody arrangement — sole, shared, or split.
Sole Custody vs. Shared Custody Calculations
Sole Custody
When one parent has the child more than 275 days per year, the standard calculation applies. The non-custodial parent pays support to the custodial parent in the amount derived from the schedule.
Shared Custody
When each parent has the child more than 90 days per year, Virginia’s shared-custody formula applies. The formula adjusts each parent’s presumptive obligation based on the number of days the child spends with each parent. Even small changes in custody time can produce material changes in support.
Split Custody
When the parents have different children primarily residing with each, separate calculations are run for each child, and the resulting obligations are offset. The net result is a single support figure flowing one direction.
Deviations from the Guideline
Virginia Code § 20-108.1 permits courts to deviate from the presumptive guideline amount when the deviation is supported by written findings and serves the child’s best interests. Common deviation factors include:
- Extraordinary medical or educational expenses;
- Special needs of the child;
- Custody arrangements outside the standard categories;
- Independent financial resources of the child;
- Significant tax consequences;
- Voluntary unemployment or underemployment;
- Other equitable considerations.
Deviation requests — whether seeking more or less than the guideline figure — require evidence and written argument.
Income Imputation and Voluntary Underemployment
When a parent is voluntarily unemployed or underemployed, the court can impute income based on earning capacity. Imputation cases often involve vocational experts, employment history, and analysis of the local job market. These are some of the most contested issues in support cases.
Self-Employment and Variable Income
When a parent is self-employed or earns variable income (bonuses, commissions, RSUs), establishing the correct income figure requires forensic analysis. Tax returns, profit-and-loss statements, K-1s, and bank records are typically pulled through discovery to construct an accurate income picture.
Enforcing a Virginia Child Support Order
When a parent fails to pay court-ordered support, enforcement tools include:
- Income withholding — automatic deductions from the obligor’s paycheck;
- Contempt proceedings — potentially leading to civil sanctions or incarceration;
- Tax-refund interception;
- Driver’s license and professional license suspension;
- Bank-account levies;
- Liens on real and personal property;
- Reporting to credit bureaus.
Modifying a Child Support Order
Child-support orders can be modified upward or downward when there is a material change in circumstances. Common triggers include a substantial income change, a change in custody arrangement, the birth of additional children, or the emancipation of a child under the existing order. See Custody and Support Modification.
When Does Child Support End in Virginia?
Child support in Virginia generally terminates when the child turns eighteen. If the child is still in high school and living with a parent, support continues until graduation or until age nineteen, whichever occurs first. Support for severely disabled children can be extended beyond the age of majority by court order.
Healthcare and Add-On Expenses
The child-support order should specify each parent’s share of uninsured medical, dental, vision, mental-health, and orthodontic expenses. Many orders also allocate extracurricular activities, private-school tuition, summer-camp costs, and college expenses, although Virginia generally does not require post-majority college contribution unless agreed to in a Property Settlement Agreement.
