Child Support in Massachusetts

Where to start

Your first step depends on what you already have. Some parents already have a court order but need payments collected. Others need to establish parentage first. Some need a change because income, custody, health coverage, parenting time, or child care costs changed.

How Massachusetts child support is set

Massachusetts child support is based on the child support guidelines. The court uses the worksheet to estimate the amount. The amount is not based only on what the other parent earns. The worksheet looks at both parents’ income and other facts.

Income is broad. The income definition includes wages, tips, overtime, self-employment income, commissions, bonuses, unemployment, workers’ compensation, pensions, certain Social Security benefits, rental income, investment income, and other sources. The guidelines also say means-tested benefits such as TAFDC, SNAP, and SSI are not counted as that parent’s income.

The worksheet can include health insurance, dental or vision insurance, child care costs, the number of children, and the parenting-time pattern. A judge can order a different amount in some cases, but the court must have a reason. Deviations may apply in special situations, such as ongoing extraordinary needs, high parenting-time costs, very low income, or facts that make the worksheet amount unfair or not in the child’s best interest.

If your case involves divorce, alimony, self-employment, cash work, overtime, disability benefits, more than two legal parents, college costs, or a child over 18, get legal help before relying on a simple estimate.

If parentage has not been established

Parentage means the legal parent-child relationship. If the other parent is not legally established, Massachusetts has two main paths. Parents may sign a Voluntary Acknowledgment of Parentage, or someone may ask the court to establish parentage.

Signing an acknowledgment can be simple when both parents agree, but it has legal consequences. A court case may be needed if there is disagreement, testing is requested, or the facts are complex. Massachusetts has court parentage forms for cases involving parentage, support, custody, and parenting time for unmarried parents.

If there are threats, abuse, sexual assault, coercion, stalking, or fear that the other parent may harm you or your child, speak with SafeLink or a legal aid office before starting contact. ASMOM’s Massachusetts safety guide may help you plan who to call first.

How to apply for help or file in court

You have two common paths. You can ask DOR Child Support Services to help, or you can file directly in Probate and Family Court. Many parents start with DOR because DOR can help locate a parent, establish parentage, get an order, collect payments, enforce support, and review some cases for changes. You can enroll with DOR online, by mail, or through listed contact options.

You can also file in court. The court’s get an order page explains which complaint may be needed. If the parents were not married and parentage is not established, the case may start with a parentage complaint. If parentage is already established, the filing may be for custody, support, and parenting time.

DOR can help with child support services, but it does not act as your personal lawyer. It also does not solve parenting time, where the child lives, or property settlement issues. Use legal aid, a lawyer, or court help if those issues are part of the case.

Documents and information to gather

You do not need every document before you ask for help, but paperwork can keep a case from stalling. For a fuller list, use ASMOM’s documents checklist. For court cases, Massachusetts keeps financial statements. The short form is generally used when annual income is under $75,000 before taxes. The long form is generally used when annual income is more than $75,000.

Payments, direct deposit, and enforcement

Support is often paid through DOR. In many cases, the paying parent’s employer withholds support from wages and sends it to DOR. DOR then sends the payment to the parent or caregiver who receives support. Parents who receive support can manage payment history and direct deposit through DOR’s receiving support page.

If payments stop, DOR may use enforcement remedies when a case meets the criteria. These can include wage withholding, bank levies, tax refund intercepts, license actions, and other collection steps. DOR also offers a virtual counter for some complex issues such as license suspension, bank levy, tax intercept, or modification.

Enforcement is not instant. Keep a simple log of missed or partial payments, notices from DOR, court dates, and any information you learn about the other parent’s job or address. If you need food or rent while waiting, look at ASMOM’s Massachusetts SNAP, Massachusetts housing, and local resources guides.

Changing, ending, or reviewing a child support order

A child support order does not change just because parents agree in a text message, one parent loses a job, or the child starts living somewhere else. The court order stays in place until it is changed by the court. If DOR is involved, DOR may be able to review the case and ask the court for a change. If DOR cannot help, it should send a letter, and you may still be able to ask the court on your own.

The 2025 guidelines say a support order may be modified if the amount under the current guidelines is inconsistent with the existing order, if health coverage changes, if health coverage is no longer reasonable, if new health coverage becomes available, or if another material and substantial change has happened.

Common reasons to ask for review include job loss, a large change in income, a change in parenting time, new health insurance, loss of health insurance, new child care costs, a child aging out of the order, or a child’s needs changing. Bring proof. Examples include pay stubs, tax returns, public assistance proof, unemployment proof, disability or injury documents, health coverage documents, and custody orders.

Massachusetts support may continue after age 18 in some cases. The state’s support after 18 page explains that support can continue for some children who are dependent and living with a parent, and up to age 23 when specific education-related conditions apply. Do not stop paying or assume payments will stop without checking your order and getting legal help.

Public benefits, safety, and legal help

If you receive TAFDC, child support rules can be different. Most people who receive TAFDC must cooperate with child support unless a good-cause reason applies. Legal aid explains that the state may keep most support paid while you receive TAFDC, while the first $50 per month in current support may be sent to the family. Read the TAFDC rules before you count child support as money you will receive directly.

If cooperation could put you or your child at risk, ask DTA, DOR, or a legal aid advocate about good cause. This can matter when there has been domestic violence, threats, stalking, coercive control, or other safety concerns. You can also read ASMOM’s family safety help guide.

If support is not enough to cover basic needs, look at other help at the same time. For child care, see Massachusetts child care. For broader state help, use Massachusetts grants. For benefit delays or closures, use ASMOM’s benefits problems guide.
