Use Form B only when each parent has the minor for at least 123 overnights per year and both contribute directly to daily expenses. This version applies to shared physical care arrangements recognized by North Carolina courts.
Enter gross monthly earnings for both parents using pay stubs or tax records, then add verified costs such as work-related care fees and medical coverage premiums paid for the minor. Inaccurate income figures or missing expense lines can shift the final amount by hundreds of dollars.
Review overnight totals with a calendar count rather than estimates. A difference of even ten nights can move the case to a different form. After completing all rows, confirm proportional shares and credits before relying on the final payment figure for filing or negotiation.
NC Child Support Calculator Worksheet B Step by Step Guide
Confirm shared physical care status before using Form B by verifying that each parent exceeds 123 annual overnights. Courts reject this form if the threshold is not met.
- Record gross monthly earnings for both parents using recent pay statements or Schedule C totals for self-employed income.
- Add monthly health coverage costs paid for the minor, separating employer-paid and out-of-pocket portions.
- List work-related care expenses with receipts or provider statements to avoid disputes.
- Calculate each parent’s income share as a percentage of combined earnings.
- Apply the overnight adjustment factor using the official state table tied to annual night counts.
Recheck numeric entries after each step, since small data errors can alter the final transfer amount. Keep a copy of the completed form for filing or mediation reference.
When Worksheet B Applies Based on Custody and Overnight Counts

Use Form B only if both parents exceed 123 overnights per year, verified through a written schedule or court order. Counts below this threshold invalidate shared-care calculations.
Base overnight totals on a 365-day period, not calendar months, and include school nights, holidays, and extended summer stays. Partial days do not qualify unless the overnight occurs.
Apply this method when physical care is substantially split, commonly near a 50/50 arrangement, but not equal in every case. A 183/182 split still qualifies if both sides pass the minimum.
Avoid Form B if one parent falls at 122 nights or fewer, since courts then require the alternate form tied to primary placement. Keep written proof of exchanges to prevent later challenges.
Entering Parent Income Dependent Care and Health Coverage Data
Record gross monthly earnings for each parent using pay stubs, tax filings, or verified employer statements, then convert hourly or weekly figures into a monthly amount using 4.333 weeks.
Include bonuses, commissions, and self-employment profit after ordinary business deductions, while excluding nonrecurring gifts or reimbursements. Use averaged figures if income fluctuates across quarters.
Enter dependent care costs paid for work or school purposes only, supported by invoices or contracts. Allocate amounts to a single parent if paid directly, not split unless invoices show shared payment.
List medical insurance premiums covering minor dependents as a separate line item, counting only incremental cost beyond self-only coverage. Do not include copays or out-of-pocket treatment charges.
Verify totals before submission since minor entry errors shift proportional shares and lead to incorrect payment figures in court review.
Reading Final Payment Amounts and Adjustments on Form B
Review final monthly figures by locating each parent’s proportional share, calculated from combined earnings and assigned overnight totals. Compare owed versus received amounts to identify which party transfers funds.
Check deviation lines for dependent care expenses, medical insurance premiums, and extraordinary costs. These entries modify base figures and shift responsibility percentages shown beside each parent name.
Confirm credit application for overnight stays exceeding guideline thresholds. Miscalculated night counts directly alter final obligations and often trigger court corrections.
Scan adjustment rows for prior payments, arrears offsets, or agreed deviations approved by court order. Any value outside guideline math must reference a signed agreement or judicial finding.
Validate rounding rules applied to cents and ensure totals align with official tables before filing, since arithmetic mismatches delay approval.
