North Carolina Child Support Guidelines: How Support Is Calculated

In North Carolina, child support is calculated using the income shares model: both parents' gross incomes are combined and run through a statewide schedule of presumptive guidelines, and the basic support obligation is then divided between the parents in proportion to each parent's share of that combined income. These guidelines are set by the Conference of Chief District Judges under N.C. Gen. Stat. § 50-13.4(c1), and by statute must be reviewed at least every four years. The current guidelines (AOC-A-162, Rev. 1/23) took effect January 1, 2023 — because a new review cycle is required at least every four years, treat any dollar figures below as time-sensitive and confirm the current numbers with your local district court or the guidelines document before relying on them.

How the Income Shares Model Works

Rather than looking at only one parent's finances, North Carolina's schedule starts by adding both parents' gross incomes together. The combined figure is matched against the statewide schedule of basic child support obligations, and each parent then owes a share proportional to their percentage of the combined income. The schedule itself is built to reflect ordinary spending on a child from birth through age 18. It does not include work-related child care costs, health insurance premiums for the child, or uninsured medical expenses over $250 per child per year — those are calculated and added separately on top of the basic obligation.

What Counts as Income

"Gross income" is defined broadly under the guidelines. It generally includes a parent's actual income before deductions, from nearly any source: salaries and wages, commissions, bonuses, dividends, self-employment or business income, rental income, pension and retirement payments, interest, trust and annuity income, capital gains, Social Security benefits, workers' compensation, unemployment benefits, disability benefits, gifts, prizes, and even alimony received from a third party (someone other than the other parent in the current case). If you are preparing a financial affidavit for a North Carolina child support case, it helps to gather documentation for every one of these categories rather than just a pay stub.

When a Court Can Impute or "Assign" Income

A parent cannot simply reduce their child support obligation by refusing to work or by taking a lower-paying job in bad faith. If a North Carolina court finds that a parent is voluntarily unemployed or underemployed for that reason, the court may calculate support based on that parent's potential or imputed earning capacity rather than their actual reported income. There are important limits, though: income may not be imputed to a parent who is physically or mentally incapacitated, and — consistent with a federal regulation, 45 C.F.R. § 302.56(c)(3) — a parent's incarceration is not treated as voluntary unemployment for this purpose.

Low-Income and High-Income Cases

The guidelines build in a self-support reserve tied to the federal poverty level for one person. Under the current guidelines, that reserve is based on the 2022 federal poverty level of $1,133 per month (also a time-sensitive figure, since the federal poverty level is updated periodically). For an obligor whose adjusted gross income falls under $1,150 per month, the guidelines require a minimum support order of $50 per month unless the court orders a deviation from the guidelines.

At the other end of the income scale, if the parents' combined adjusted gross income exceeds $40,000 per month (roughly $480,000 per year), the standard schedule stops applying altogether. In that situation, North Carolina courts instead set support to meet the child's reasonable needs, considering the family's accustomed standard of living, rather than mechanically applying the schedule.

Which Worksheet Applies to Your Case

North Carolina uses three different worksheets depending on the custody arrangement:

• Worksheet A applies when one parent has primary physical custody — meaning the child lives with that parent for 243 nights or more per year.
• Worksheet B applies to shared custody, where each parent has the child for at least 123 nights per year. Under Worksheet B, the combined basic support obligation is multiplied by 1.5 before it is divided between the parents.
• Worksheet C applies to split custody, where there are two or more children and each parent has primary custody of at least one child.

Because the worksheet depends on actual overnights rather than the label used in a custody order, it's worth counting nights carefully — a schedule that looks "50/50" on paper may not actually cross the 123-night threshold once vacations, holidays, and travel are accounted for.

Modifying an Existing Order

A North Carolina child support order is not locked in forever, but it also cannot be changed just because one parent wants a different number. Under N.C. Gen. Stat. § 50-13.7, a modification generally requires a substantial change of circumstances. The guidelines add a helpful presumption: if the existing order is at least three years old, and recalculating support on the parents' current incomes under the current guidelines would produce a result that differs from the existing order by 15% or more, that difference is presumed to be a substantial change of circumstances supporting modification.

How Support Orders Are Enforced

Federal law provides the backbone that makes North Carolina's enforcement tools work, and that also makes support orders hard to escape by moving or by filing bankruptcy:

• Under 42 U.S.C. §§ 654, 659, and 666, states must run a child support enforcement (Title IV-D) program and must have tools such as automatic income withholding, license suspension, and liens available; federal wages and benefits can also be garnished to satisfy support obligations.
• If the other parent lives out of state, 28 U.S.C. § 1738B requires every state to enforce a validly issued child support order from another state and generally prevents a second state from modifying it outside narrow continuing-jurisdiction rules — this works together with North Carolina's version of the Uniform Interstate Family Support Act (UIFSA).
• In bankruptcy, child support and alimony are treated as a "domestic support obligation": they cannot be discharged (11 U.S.C. § 523(a)(5)) and are paid before most other unsecured debts (11 U.S.C. § 507(a)(1)). Property-settlement debts from a divorce decree are also generally non-dischargeable in a Chapter 7 case under § 523(a)(15).

Separately, if a custody dispute involves another state — for example, a parent relocating with the child — North Carolina's Chapter 50A adopts the Uniform Child-Custody Jurisdiction and Enforcement Act (UCCJEA), which governs which state's court has authority to make custody decisions. That jurisdictional question is distinct from how much support is owed, but it can come up in the same overall case.

What You Can Do in North Carolina

1. Gather full income documentation for both parents before your hearing — pay stubs, tax returns, and records for any of the broader income categories listed above (self-employment, rental income, benefits, etc.), since the guidelines calculation depends on combined gross income.
2. Count actual overnights for the current or proposed custody schedule so you know whether Worksheet A, B, or C applies — this changes the math significantly, especially the 1.5 multiplier under Worksheet B.
3. Add in child care, health insurance, and uninsured medical costs separately, since the basic schedule does not already include them (except uninsured medical costs of $250 or less per child per year).
4. If you are separated and also need a divorce or postseparation support, note that North Carolina does not require a written separation agreement to be legally separated — you simply need to be living in separate homes with at least one party intending the separation to be permanent. The state's Guide & File online service can help prepare court documents for certain case types, including absolute divorce.
5. If you need support before a final order, postseparation support under N.C. Gen. Stat. § 50-16.2A is a separate, temporary remedy based on financial needs, standard of living, income, earning ability, debt obligations, and each party's other support obligations — ask the clerk of court or a family law attorney whether it applies to your situation.
6. If you believe your order is out of date, compare your existing order's amount to what current incomes would produce under the guidelines — if your order is at least three years old and the gap is 15% or more, you may have grounds to file a modification motion.
7. If the other parent is out of state or not paying, contact North Carolina's child support enforcement (IV-D) agency about wage withholding, license suspension, or liens, and know that a valid North Carolina order should be enforceable in any other state under federal law.

Time-Sensitive Facts to Double-Check

• The guidelines effective January 1, 2023, are due for another statutory review by North Carolina's four-year cycle — confirm you are looking at the current schedule.
• The self-support reserve figures ($1,133/month poverty level basis; $1,150/month minimum-order threshold; $50/month minimum order) are tied to a 2022 federal poverty level snapshot and can change with future guideline revisions.
• The $40,000-per-month combined-income cap for the standard schedule is a guideline-specific figure that can also be revised.
