Estimate monthly child support payments in Massachusetts using the state's Income Shares formula. Updated for 2026 guidelines.
Massachusetts Child Support Guidelines (2021 update) use combined gross income. Parenting time adjustment with cross-reference to custody arrangement.
| Children | Percentage of Combined Income |
|---|---|
| 1 Child | 21% |
| 2 Children | 30% |
| 3 Children | 35% |
| 4 Children | 38% |
| 5+ Children | 41% |
In Massachusetts, if a parent is voluntarily unemployed or underemployed, the court may impute income based on the parent's earning capacity, work history, education, and local job market conditions. Under the income-shares model, both parents' incomes are considered to determine the total child support obligation.
The Massachusetts child support enforcement agency handles establishing, modifying, and enforcing child support orders. They can assist with locating non-custodial parents, establishing paternity, and collecting past-due support through wage garnishment, tax intercepts, and other enforcement tools.
