North Carolina Child Support Overview

North Carolina uses the income shares model for calculating child support. This model is based on the principle that children should receive the same proportion of parental income they would have received if the family were intact. Both parents’ incomes are combined, and the support obligation is divided proportionally.

North Carolina uses the Income Shares Model. Both parents’ gross incomes are combined, then the basic child support obligation is determined from economic tables (schedule set by the Conference of Chief District Court Judges, last revised January 1, 2023). Each parent’s share is proportional to their percentage of combined income. NC uses three worksheets: Worksheet A for primary custody (non-custodial parent has fewer than 123 overnights/year), Worksheet B for shared/joint custody (each parent has at least 123 overnights/year, with a 1.5x multiplier on the basic obligation to account for duplicated housing costs), and Worksheet C for split custody (each parent has primary custody of at least one child). The combined gross income cap is 40000 per month; above that, courts have discretion based on the child’s reasonable needs. The minimum order is 50 per month.

How North Carolina Calculates Child Support

The North Carolina child support calculation considers multiple factors:

1. Determine each parent’s gross income — wages, salary, commissions, bonuses, self-employment income, investment income, and other sources.
2. Calculate combined parental income — add both parents’ adjusted gross incomes together.
3. Apply the guideline schedule — North Carolina’s guidelines provide a base support amount based on combined income and number of children.
4. Prorate between parents — each parent’s share is proportional to their percentage of the combined income.
5. Add healthcare and childcare costs — these are added to the base amount and divided proportionally.
6. Apply adjustments — parenting time credits, other child obligations, and special circumstances may adjust the final amount.

What Counts as Income in North Carolina

Gross income before deductions for federal/state taxes, Social Security, Medicare, health insurance, or retirement contributions. Included sources: wages, salaries, commissions, bonuses, self-employment income (gross receipts minus ordinary and necessary business expenses), rental income, royalties, retirement/pension distributions, interest, dividends, trust income, annuities, capital gains, workers’ compensation, unemployment insurance, disability pay, Social Security benefits, alimony received from another relationship, gifts, prizes, and significant in-kind payments (company car, free housing) that reduce personal living expenses. Excluded: means-tested public assistance (TANF, SSI, food stamps), employer-paid taxes or health insurance, and benefits received by or on behalf of the child. For self-employment, IRS non-cash deductions like depreciation and investment tax credits are NOT permitted reductions.

Imputed income: YES. Courts may impute income when a parent is voluntarily unemployed or underemployed in bad faith to minimize or avoid child support. The court must find the income reduction is not the result of good faith actions. Imputed income is based on recent work history, occupational qualifications, and prevailing employment opportunities in the community. If the parent has no recent work history or vocational training, income is imputed at minimum wage for a 35-hour work week. Income is NOT imputed to parents who are physically or mentally incapacitated.

Deviation factors: The court may deviate from guidelines if applying them would not meet or would exceed the child’s reasonable needs, or would be unjust or inappropriate. Specific factors include: (1) one parent pays 100% of both support and health insurance; (2) self-support reserve applies and parent also pays childcare, insurance, or extraordinary expenses; (3) custodial parent incurs childcare while attending school; (4) parent receives actual childcare tax credits; (5) either party pays alimony to current or former spouse; (6) parent pays support for multiple families under separate orders; (7) child has special needs with extraordinary medical, educational, or psychological expenses; (8) extraordinarily high or low income outside Guidelines schedule; (9) private school tuition or special educational expenses; (10) high transportation costs for custody exchanges when parents live far apart. Written findings required stating the guideline amount, basis for deviation, and how deviation serves the child’s best interest.

Healthcare & Childcare in North Carolina Child Support

Health insurance: All child support orders must require one or both parents to provide health insurance for the child if available through employer or group coverage. Health insurance is considered reasonable in cost if it does not exceed 5% of the providing parent’s gross income. The parent providing insurance receives a credit in the child support calculation. If a parent ordered to provide insurance fails to do so, that parent is liable for all medical expenses that would have been covered. Unreimbursed medical expenses not covered by insurance are typically divided between parents in proportion to their respective incomes. Statutory authority: N.C.G.S. Section 50-13.11.

Childcare costs: Work-related childcare costs are a standard component of the NC child support worksheet calculation. Eligible expenses include regular daycare, pre-K programs, before/after-school care, work-related summer camps, babysitters, nannies, and childcare while seeking employment. Total annual cost is divided by 12 for a monthly average. Both parents share the cost proportionally based on their income shares. The paying parent may receive a credit reducing their obligation. Childcare incurred while attending school (not work) may serve as a basis for deviation from guidelines.

When Does North Carolina Child Support End?

In North Carolina, child support generally ends when the child reaches 18, but if the child is still enrolled in primary or secondary school (high school) at age 18, support continues until the earliest of: graduation, ceasing regular school attendance, failing to make satisfactory academic progress, or reaching age 20. Early termination occurs upon legal emancipation, marriage, or enlistment in the U.S. Armed Forces on active duty. Statutory authority: N.C.G.S. Section 50-13.4(c).. However, support may continue or end earlier based on:

• The child graduates from high school (if still a minor)
• The child becomes emancipated (marriage, military service, self-supporting)
• The child has special needs requiring ongoing support
• College support: NO. North Carolina courts cannot order parents to pay college tuition or expenses. There is no statutory authority for court-ordered college support. However, parents may voluntarily agree to contribute to college costs in a separation agreement or consent order, which is then enforceable as a contract.

Modifying North Carolina Child Support

When to modify: A difference of 15% or more between the current order amount and the amount that would result from applying current guidelines to current circumstances is presumed to be a substantial change in circumstances. Orders may also be reviewed after 3 years since entry or last modification. Other qualifying changes include involuntary job loss or substantial income reduction, significant increase in child’s needs, change in custody arrangement, significant changes in childcare or healthcare costs, and disability of a parent. Voluntary income reduction does not qualify (courts may impute income). Statutory authority: N.C.G.S. Section 50-13.7.

How to modify: File a motion to modify with the court that issued the existing child support order. The motion must include updated financial information. The court holds a hearing to determine whether modification is warranted. Parents may also request a review through North Carolina Child Support Services (CSS) if they have an open case with the agency. CSS can initiate the modification process administratively or refer the case to court.

Either parent can request a modification. Changes are typically not retroactive to before the date of filing the modification request.

North Carolina Child Support Enforcement

North Carolina has multiple tools to enforce child support orders when a parent fails to pay:

• Income withholding (wage garnishment)
• contempt of court (civil contempt with possible incarceration until purged)
• federal and state tax refund interception
• state lottery winnings interception
• bank account seizure/levy
• property liens on real or personal property
• driver’s license suspension
• professional/occupational license suspension
• recreational license suspension (hunting/fishing)
• passport denial or revocation (when arrears exceed 2500)
• credit bureau reporting
• arrest and bail under Article 34 Chapter 1 of the General Statutes

Additional North Carolina rules: (1) NC uses three distinct worksheets (A, B, C) for different custody arrangements — unusual among states. (2) The 123-overnight threshold distinguishes primary from shared custody. (3) Shared custody Worksheet B applies a 1.5x multiplier to the basic support obligation for duplicated housing costs. (4) Guidelines are set by the Conference of Chief District Court Judges, not the legislature directly. (5) Combined gross income cap is 40000/month; above that, courts exercise discretion. (6) Minimum support order is 50/month even for low-income obligors. (7) Under N.C.G.S. Section 50-13.10, vested arrearages cannot be retroactively reduced — strong protection for custodial parents. (8) Self-support reserve is 1133/month (per 2023 guidelines based on 2022 federal poverty level for one person). (9) Extraordinary expenses such as private school tuition, long-distance transportation for custody exchanges, and counseling can be added to the basic obligation and shared proportionally by income.
