Child Support — Built on the Real Numbers

What child support costs depends on the custody arrangement and each parent’s income and expenses. The guidelines do the math for most families; for higher incomes and complicated finances, the real work is getting the income right.

Calculating Child Support

To estimate child support in North Carolina, use the worksheet* that best describes your custody situation:

• North Carolina Child Support Guidelines — Using the Worksheets
• Child Support Worksheet A — Primary Custody
• Child Support Worksheet B — Joint/Shared Custody
• Child Support Worksheet C — Split Custody

These worksheets are created, copyrighted, and maintained by the North Carolina Administrative Office of the Courts (AOC). For additional forms, visit the North Carolina Courts website.

The Guidelines and the “Income Shares” Model

The guidelines calculate a child support obligation for families with combined incomes up to $480,000 per year (about $40,000 per month). Above that, there is no formula — the court sets support case-by-case, based on the child’s reasonable needs and the parents’ ability to pay. The guidelines are reviewed periodically.

North Carolina uses the “income shares” model: child support is a shared parental obligation, and a child should receive the same proportion of parental income he or she would have received if the parents lived together. As a result, when one parent’s income increases, the basic child support obligation increases too — contrary to the popular misconception that “if my ex’s income goes up, my child support will go down.”

What the Guidelines Leave Out — and When to Deviate

The guidelines are built on economic data estimating average household spending on children from birth to age eighteen, and they exclude child care, health insurance, and health-care costs in excess of $250 per year. Visitation expenses are not built into the schedule, so a parent who incurs substantial visitation-travel costs may file a motion to deviate from the guidelines. The guidelines also assume the parent who receives support claims the child’s tax exemption; where that parent has little or no income-tax liability, the court may assign the exemption to the paying parent and deviate. Deviation runs both ways — up or down — when the guideline figure doesn’t fit the child’s reasonable needs.

When the Income Is Complicated

Above the guideline cap — and whenever income is bonus-heavy, irregular, or self-employment — the number turns on what is actually earned, not just what a tax return shows. We build support on real income, including add-backs for depreciation and perks that understate a self-employed parent’s true earnings, so the figure reflects reality.

Child Support Is Its Own Claim — and It Can Change

Child support is a separate claim: you don’t have to be divorced to establish or modify it, and unlike alimony and property division, it isn’t lost when the divorce is entered. It can also be modified — generally on a substantial change of circumstances, or after three years when the guideline amount would differ from the current order by 15% or more.

Collecting & Enforcing Child Support

If you are the custodial parent and the other parent has neglected to pay, contact the North Carolina Child Support Enforcement (CSE) Agency, which helps secure financial and medical support from parents — for as little as $25.

Retroactive Child Support

Once a child support order is entered, support is vested and not subject to retroactive modification under N.C. Gen. Stat. § 50-13.10. But where no child support order has been established, North Carolina law allows you to recover child support retroactively from the other parent for the past three years.
