Child Support in Nantucket County, Massachusetts: How Much Will You Owe?

Quick answer: it depends on both parents' incomes, how many children you have, and the parenting schedule. The calculator on this page turns those numbers into a real guideline estimate in about a minute. It is an educational estimate, not legal advice, and the judge always sets the final amount. FamilyCourtHelp.com is a self-help resource, not a law firm.

How much child support will you owe in Nantucket County, Massachusetts? There is no flat rate. Massachusetts uses one statewide formula, and the number moves with each parent's income, the number of children, and how many overnights the kids spend with each of you. This page walks through how the math works, and you can run your own estimate right here.

Massachusetts follows the Income Shares model under the Massachusetts Child Support Guidelines. The court combines both parents' monthly net incomes, looks up the basic support obligation on the state's guideline schedule for that income level and number of children, then prorates the obligation between the parents according to each parent's percentage share of the combined income.

What counts as income? Massachusetts runs the formula on net income, meaning income after taxes come out. Gross income from any source including salary, wages, commissions, self-employment, bonuses, severance, royalties, rental income, retirement, Social Security, workers' compensation, unemployment, and interest. Means-tested benefits are excluded.

Parenting time matters directly in Massachusetts: the number of overnights each parent has changes the math itself. Massachusetts uses a shared-care formula rather than a simple per-overnight credit. When parents roughly share physical custody, the Massachusetts Child Support Guidelines run a separate shared physical custody calculation that can lower the support number compared to a standard order. The more balanced the parenting time, the more the formula reflects each parent's direct spending on the child. The on-page calculator here is only an estimate, so confirm any shared-custody result against the official worksheet.

When does it end? Massachusetts child support can continue to age 23 if the child is principally dependent on the parent and pursuing a full-time post-secondary education program. Standard termination is age 18.

Can the amount change later? File a complaint for modification in Probate and Family Court, or request review through DOR/CSE. Inconsistency with current guidelines supports modification.

If payments fall behind, Massachusetts has real enforcement tools. Massachusetts DOR/CSE uses immediate income withholding, tax intercept, license suspension, lien filings, credit reporting, passport denial, and contempt referrals to Probate and Family Court.
