Child Support in Virginia: How It's Calculated
Virginia uses the Income Shares Model (§20-108.2) to determine child support obligations. This guide walks through how the formula works, what factors Virginia courts consider, and how to modify or enforce an order — with links to official Virginia resources.
Income Shares Model (§20-108.2) in Virginia
Virginia uses the Income Shares Model under Virginia Code §20-108.2. Both parents' combined gross incomes are applied to the Virginia Child Support Schedule to determine a basic obligation, which is then divided proportionally based on each parent's income share.
Virginia provides a shared custody credit when the non-primary parent has the child for at least 91 overnights per year (approximately 25%). The credit increases on a sliding scale as overnights increase. Virginia courts may deviate from the guideline upon written findings, including consideration of the child's actual needs, debts of the parties, and the standard of living of the child.
Key Factors Virginia Courts Consider
- Both parents' gross monthly income
- Number of children
- Overnights with non-primary parent — 91+ triggers the shared custody credit
- Child's health insurance costs
- Work-related childcare expenses
- Extraordinary medical or educational expenses
- Existing support obligations for other children

Step-by-Step: How Virginia's Formula Works
Here is how Virginia applies the Income Shares Model (§20-108.2) to calculate a child support obligation, step by step:
1. Determine each parent's income
Virginia starts by calculating each parent's income — gross income (before taxes). The specific definition of income is set by Income Shares Model (§20-108.2).
2. Combine incomes and find the basic obligation
Both parents' incomes are combined and compared to Virginia's child support schedule. The schedule produces a basic child support obligation based on combined income and the number of children.
3. Add health insurance and childcare costs
Health insurance premiums paid for the child and work-related childcare expenses are added to the basic obligation before it is divided between parents.
4. Divide proportionally based on income share
The total obligation is allocated between the parents in proportion to each parent's share of combined income. The parent with the higher income share bears a larger portion of the obligation.
5. Apply parenting time credits
Overnights with non-primary parent — 91+ triggers the shared custody credit shared custody credit when the non-primary parent has the child for at least 91 overnights per year (approximately 25%).
Modifying Child Support in Virginia
In Virginia, a parent can seek modification of child support by showing a material change in circumstances since the last order — such as a 25% or greater change in either parent's income, a change in custody or parenting time, or a change in the child's needs. Virginia also permits a review every 3 years without needing to prove a material change. The modification must be filed in the Juvenile and Domestic Relations District Court that issued the original order. Support modifications are not retroactive — any reduction only applies from the date the modification petition was filed and served.
How Virginia Enforces Child Support Orders
Virginia's Division of Child Support Enforcement (DCSE) can enforce orders through income withholding, tax refund interception, license suspension (driver's, professional, and recreational), reporting arrears to credit bureaus, placing liens on real and personal property, and contempt of court. Virginia also uses the Case Adjudication and Revenue Collection System (CARCS) to track and manage cases. Parents who fall behind by more than $5,000 may face passport denial under federal law.
