Child Support in North Carolina
How the income shares guidelines actually work, why the 123-overnight threshold decides your worksheet, what counts as income, and when a court will deviate from the number.

North Carolina uses an income shares model
The idea behind the North Carolina Child Support Guidelines is simple: estimate what the parents would have spent on the child if the household had stayed together, then divide that amount between them in proportion to their incomes. The guidelines produce a presumptive amount for combined incomes within the published schedule, and the court can deviate when the presumptive amount would be unjust or inappropriate.
What goes into a North Carolina child support calculation
- Both parents’ gross monthly income
- Overnights with each parent
- Health insurance for the child
- Work-related child care
- Extraordinary expenses
Three worksheets, and the one you use matters
The number changes dramatically depending on which worksheet applies, and the worksheet is determined by the overnight schedule, not by what the parents call their arrangement.
| Worksheet | When it applies | Effect on the number |
|---|---|---|
| Worksheet A | One parent has primary physical custody (the other has fewer than 123 overnights per year) | Straight income-shares calculation |
| Worksheet B | Shared custody: each parent has at least 123 overnights per year | Applies a shared-custody adjustment, usually reducing the transfer |
| Worksheet C | Split custody: each parent has primary custody of at least one child | Runs two calculations and offsets them |
The 123-overnight threshold is why parenting schedules and child support are negotiated together, never separately.
What counts as income
Gross income is broader than a paycheck. It generally includes wages, salary, commissions, bonuses, overtime, self-employment income after ordinary and necessary business expenses, severance, pensions, retirement income, rental income after expenses, and in some cases recurring gifts. It generally does not include public assistance benefits, and child support received for a different child is treated separately.
Where a parent is voluntarily unemployed or underemployed in bad faith, the court can impute income based on earning capacity rather than actual earnings.
The three add-ons that change the number most
- Health insurance. The cost attributable to the child, not the whole family premium, is added to the basic obligation and shared.
- Work-related child care. Daycare and after-school care needed so a parent can work or look for work is added. Bring documentation, not estimates.
- Extraordinary expenses. Private school, special needs services, long-distance travel for visitation and similar costs can be added at the court’s discretion.
Order of operations in a guideline calculation
When the guideline amount does not apply
Either parent can ask the court to deviate from the guidelines. The party requesting it must show that applying the guidelines would not meet or would exceed the reasonable needs of the child, or would otherwise be unjust or inappropriate. Deviation comes up most often with very high combined incomes, a child with extraordinary medical needs, or a parent supporting other dependents.
When combined income exceeds the top of the published schedule, the guidelines do not set a presumptive amount and the court determines support based on the reasonable needs of the child and the relative ability of each parent to pay.
Modifying support
A child support order can be modified on a showing of a substantial change in circumstances. In many cases a party can establish that by showing the order is at least three years old and the guideline amount differs from the existing order by fifteen percent or more. A significant involuntary change in income, a change in custody, or a change in the cost of health insurance or child care can also qualify.
Two hard truths: an informal agreement to pay less does not change a court order, and modifications are generally effective from the date the motion is filed rather than the date circumstances changed. Waiting is expensive.
Nothing generates arrears faster than two reasonable people agreeing, by text message, to change a court order.Christopher Adkins, Adkins Law
Enforcement
Unpaid child support is enforced by motion for contempt, income withholding, interception of tax refunds, license revocation and other remedies. Child support in North Carolina generally continues until the child turns eighteen, or until graduation from high school if the child is still enrolled and progressing, not to exceed age twenty.
Frequently asked questions
How is child support calculated in North Carolina?
Under the income shares model: both parents’ gross incomes are combined, a basic obligation is taken from the published schedule, health insurance and work-related child care are added, and the total is divided in proportion to income using worksheet A, B or C depending on overnights.
What is the 123 overnight rule?
If each parent has the child at least 123 overnights per year, the shared custody worksheet B applies, which usually lowers the transfer amount compared with worksheet A.
Does child support cover daycare and health insurance?
Work-related child care and the child-attributable portion of health insurance premiums are added into the calculation and shared, rather than being paid separately on top of a guideline figure.
Can we agree to no child support?
Parents can agree on an amount, but a court is not bound by an agreement that fails to meet the reasonable needs of the child, and child support terms are always subject to court review.
When does child support end in North Carolina?
Generally at age eighteen, or on graduation from high school if the child is still enrolled and progressing, but not beyond age twenty.
What if I lose my job?
File a motion to modify promptly. Modifications are typically effective from the date of filing, so waiting means support continues to accrue at the old rate.
Run the numbers before you agree to them
Support figures are easy to get wrong and expensive to fix. Adkins Law can calculate the guideline amount for your actual schedule and income, and can tell you whether deviation is realistic in your case.
