Child Support Calculation Worksheet

IMPORTANT: THIS IS A PREPARATION GUIDE — NOT THE OFFICIAL COURT WORKSHEET

Maryland requires the use of official form CC-DR-034 (Worksheet A) or CC-DR-035 (Worksheet B, Shared Custody) for child support calculations.
This template provides the substantive content and calculation methodology to help you
prepare — but you must transfer your figures to the official worksheet before filing.

10. MARYLAND-SPECIFIC NOTES

• Income Shares Model: Maryland uses the Income Shares Model under Fam. Law § 12-202, considering both parents' adjusted actual incomes.
• Multifamily Adjustment (2025): Effective October 1, 2025, HB 275 introduced a multifamily adjustment reducing a parent's adjusted actual income by 75% of the basic obligation for additional children in the household for more than 92 overnights per year. Documentation is required.
• Shared Physical Custody: When each parent has the child for 128 or more overnights per year (35%), the shared physical custody formula applies under § 12-204(a).
• Above-Guidelines Income: For combined adjusted income exceeding $15,000/month, the court has discretion in setting support above the schedule amount.
• Voluntary Impoverishment: Courts may impute income if a parent is voluntarily impoverished (§ 12-201(b)(2)).
• Modification: Either party may seek modification upon a material change in circumstances.
