For parents in Northern Virginia, understanding child support is about more than just a monthly payment—it’s about ensuring your child’s needs are met while maintaining your own financial stability.
In Virginia, child support is not a “guess.” It is a mathematical calculation governed by Virginia Code § 20-108.2. However, recent legislative updates in 2025/2026 have significantly changed how support is calculated for mid- to high-income families.
The Income Shares Model
Virginia uses the “Income Shares Model.” This assumes that the child should receive the same proportion of parental income that they would have received if the parents lived together. The state combines both parents’ gross incomes, looks up a “basic obligation” in a statutory table, and then divides that cost proportionally based on what each parent earns.
3 Critical Updates for 2026
If you haven’t looked at the child support guidelines recently, your previous understanding may be outdated:
- Expanded Income Cap: The statutory schedule has been expanded to cover combined monthly gross incomes up to $42,500. Previously, anything over $35,000 was left largely to judicial discretion.
- High-Income Multipliers: For families earning above the $42,500 threshold, Virginia now uses a specific percentage (ranging from 2.6% to 5.0%, depending on the number of children) to calculate the additional support owed on that “extra” income.
- The Medical Expense Shift: Parents now share all unreimbursed medical and dental expenses proportionally. The old “first $250” deductible paid by the custodial parent has been removed in newer orders to simplify the process.
The Step-by-Step Calculation
1. Determine “Gross Monthly Income.”
In Virginia, “Gross Income” is defined very broadly. It includes:
- Salaries, wages, and bonuses.
- Commissions and severance pay.
- Dividends, interest, and rental income.
- Note: It does not include federal SSI or certain public assistance benefits.
2. Apply Mandatory Deductions
You can subtract specific costs from your gross income before the calculation begins, such as:
- Spousal support paid to a different ex-spouse.
- Child support paid for children from a different relationship.
- Half of any self-employment tax paid.
3. Account for “Add-Ons.”
The “Basic Obligation” from the state table only covers food, shelter, and clothing. The court then adds the following to that total:
- Health Insurance Premiums: Only the portion specifically covering the child.
- Work-Related Childcare: The cost of daycare or after-school care is necessary for parents to work.
How Custody Changes the Math
The amount you pay or receive depends heavily on your parenting time:
- Sole Custody: Used when one parent has the child for 275 or more nights per year. The non-custodial parent pays their full proportional share to the custodial parent.
- Shared Custody: Used when the non-custodial parent has the child for more than 90 nights per year. This triggers a different, often lower, calculation that accounts for the expenses the parent incurs while the child is in their home.
Frequently Asked Questions
Q: Can a judge deviate from the guidelines?
Yes. While the guidelines are a “rebuttable presumption,” a judge can move the number up or down based on factors like a child’s special needs, extraordinary travel costs for visitation, or the standard of living established during the marriage.
Q: Does child support end exactly at age 18?
Usually, yes. However, under Virginia Code § 20-124.2, support continues until age 19 or high school graduation (whichever comes first) if the child is still a full-time student and living at home.
Q: What if the other parent is “voluntarily unemployed”?
If a parent is capable of working but chooses not to, the court may “impute income.” This means the court calculates support based on what they should be earning, rather than what they are actually reporting.
