Massachusetts Child Support Calculator & Guide (2025)
Overview of Massachusetts Child Support
Massachusetts uses the Income Shares Model under the Massachusetts Child Support Guidelines (updated 2021). In 2021, Massachusetts reformed its child support guidelines, moving from a percentage-based model to an Income Shares approach that considers both parents' incomes and creates a more equitable system.
The Massachusetts Department of Revenue - Child Support Enforcement administers the guidelines. Massachusetts is notable for its relatively high self-support reserve of $1,287 per month and its provision for college contributions through age 23.
How Child Support Is Calculated in Massachusetts
The Massachusetts child support formula works as follows:
- Determine each parent's monthly income from all sources including wages, salaries, commissions, bonuses, self-employment income, and investment income
- Combine both parents' incomes to get the total household income
- Use the state schedule to find the basic support obligation based on combined income and number of children
- Allocate each parent's share proportionally based on their percentage of the combined income
- Add health insurance premiums and childcare costs to the base obligation
- Apply adjustments for reciprocal support orders, college contributions, and the self-support reserve

Key Factors in Massachusetts Calculations
2021 Reform
Massachusetts significantly reformed its child support guidelines in 2021, transitioning from a percentage-based model to the Income Shares Model. This reform ensures that both parents' incomes are considered and that the support obligation is distributed proportionally based on each parent's financial capacity.
Reciprocal Support Orders
Massachusetts allows for reciprocal support orders between parents. This means that in certain situations, the court can order support payments from one parent to another and vice versa, depending on the specific circumstances of the case.
College Contributions
Massachusetts may order college contributions as part of a child support order, potentially through age 23. The court considers each parent's financial capacity, the child's educational needs, and the availability of financial aid when determining college support orders.
Health Insurance Considerations
The court specifically considers the cost of adding children to health insurance coverage when determining the support obligation. Health insurance premiums are added to the base obligation and shared proportionally between the parents.
Minimum and Maximum Amounts
Self-support reserve: $1,287 per month (2024). This is one of the higher self-support reserves among states, ensuring the paying parent retains enough income for their own basic living expenses.
Minimum support: Massachusetts does not set a fixed statutory minimum, but the court will ensure the support amount is appropriate given the financial circumstances of both parents.
Income table: The Massachusetts support schedule covers combined incomes up to $10,000 per month. For incomes above this level, the court has discretion to determine an appropriate support amount.
Modification and Enforcement
Modification
Massachusetts allows modification of child support orders when:
- There has been a material change in circumstances
- A significant change in either parent's income
- Changes in custody or parenting time arrangements
- Changes in the child's needs (medical, educational, etc.)
- The child reaches the age of majority or graduates from college
Enforcement
The Massachusetts Department of Revenue - Child Support Enforcement enforces child support through:
- Income withholding from paychecks
- Tax refund interception (federal and state)
- Driver's license suspension
- Professional license suspension
- Credit bureau reporting
- Contempt of court proceedings
- Liens on property and financial accounts
- Passport denial for arrears exceeding $2,500
