10. MASSACHUSETTS-SPECIFIC NOTES

• Income Shares Model: Massachusetts uses the Income Shares Model under the Child Support Guidelines, considering both parents' gross incomes.
• 2025 Guidelines Effective December 1, 2025: The current guidelines apply to combined incomes up to $450,000/year (increased from $400,000).
• Child Multipliers: 1.00 (1 child), 1.20 (2 children), 1.27 (3 children), 1.32 (4 children), 1.35 (5 children).
• Childcare Cap: Up to $430/week for childcare may be apportioned between parents.
• Parenting Time: The Guidelines address three scenarios: (i) approximately equal shared time; (ii) 2/3 Recipient / 1/3 Payor; (iii) split custody.
• Extended Support: Support may extend to age 21 (if dependent) or age 23 (if in undergraduate program), which is atypical among states.
• Modification: Either party may seek modification upon a material change in circumstances or upon the issuance of new guidelines.
