Child support in North Carolina is less a negotiation than a math problem, and on January 1, 2027, the math changes. The Conference of Chief District Court Judges adopted revised Child Support Guidelines at its October 7, 2026 meeting after a statewide review, a public hearing in Raleigh, and an economic study of what families actually spend on children. Any support hearing held on or after January 1, 2027 uses the new rules, even if the case was filed earlier.

This guide explains how the formula works, what changed for 2027, and how to modify or enforce an order. If you want to run numbers, start with our 2027 North Carolina child support calculator, then read on to understand what the result means.

How the income-shares formula works

North Carolina uses an income-shares model. The idea is simple: a child should receive the share of parental income the child would have enjoyed if the parents lived together.

A judge must use the guidelines unless a party asks to deviate and the court finds, with written findings, that applying them would exceed or fail to meet the child’s reasonable needs or would otherwise be unjust or inappropriate.

What changes on January 1, 2027

• A new support schedule. Every income level was recalculated from updated household spending data by the Center for Policy Research. Expect different numbers for the same incomes; some go up, some go down.
• Higher-income cases. The schedule now runs to $50,000 per month in combined adjusted gross income ($600,000 a year). Above that, support is set case by case based on the children’s reasonable needs and the parents’ ability to pay; the schedule may still be used as evidence.
• Low-income obligors. Absent a deviation, the minimum order is $100 a month for a parent whose adjusted gross income is under $1,600 a month, regardless of how many children. In that “shaded area” on Worksheet A, support is based on the obligor’s income alone and generally excludes child care and health insurance add-ons.
• One-time and irregular income. Bonuses, commissions and other nonrecurring income can be averaged or prorated, or handled by a percentage approach that applies the same share of income to the bonus when it is received.
• Clearer terms. The guidelines now clearly distinguish prospective support (from the filing date forward), retroactive support (for the period before filing, typically up to three years) and arrears (unpaid amounts under an existing order).

The three worksheets

What counts as income, and imputed income

The guidelines start with gross income from almost any source: salary and wages, commissions, bonuses, self-employment and business income (minus ordinary and necessary expenses), rental income, dividends, pensions, Social Security retirement and disability benefits, unemployment, workers’ compensation, and alimony received from someone other than the other parent. Means-tested public assistance such as SNAP or TANF is not counted.

If a parent is deliberately unemployed or underemployed in bad faith, the court can impute income based on earning capacity. This is a frequent battleground for business owners, commissioned salespeople and parents who quit or downshift after separation.

Modifying a child support order

A child support order can be changed under G.S. 50-13.7 when there is a substantial change in circumstances. The guidelines create a helpful shortcut: if the order is at least three years old and a new guidelines calculation would produce an amount that differs by 15% or more, a substantial change is presumed. Because the 2027 schedule changed every income level, practitioners expect more modification filings, especially for orders entered in 2023 or earlier.

Other common grounds: job loss or a large raise, a change in custody, new child care costs, or changes in a child’s medical needs. A modification generally applies from the date the motion is filed, so file promptly.

Enforcing an order in Mecklenburg County

When support is not paid, the receiving parent can file a motion for contempt (an order to show cause) or work with North Carolina Child Support Services. Tools include income withholding, interception of tax refunds, liens, suspension of driver’s and professional licenses, and, for willful nonpayment, jail until a purge amount is paid. A parent facing contempt can defend by showing an inability to comply that was not willful.

When child support ends

Support generally continues until the child turns 18. If the child is still in primary or secondary school at 18, support continues until graduation, until the child stops attending regularly, or until age 20, whichever comes first (G.S. 50-13.4(c)). Parents may agree in a contract to pay more, such as college costs, and those agreements can be enforced as contracts.
