Child Support in Maryland
Maryland calculates child support under the income shares model. This is set out in the Family Law Article, section 12-204 of the Maryland Code. The guideline combines both parents' adjusted actual income into a schedule of basic child support obligations. A self-support reserve is built in. It protects a lower-income paying parent's ability to meet their own basic needs. Maryland circuit courts hear child support matters. The Child Support Administration is the state's IV-D agency. It is part of the Department of Human Services. The agency helps parents apply for and manage support services.

The income shares guidelines and the self-support reserve
Family Law § 12-204 sets the formula. Maryland combines both parents' adjusted actual income into a schedule of basic child support obligations. The schedule is organized by combined income and number of children. If combined income falls between two amounts on the schedule, the obligation is extrapolated to the next higher figure. Above the schedule's top income level, the court has discretion in setting the amount. Maryland's schedule also includes a self-support reserve, marked on the published table. This reserve adjusts the calculated obligation for lower-income parents, so a paying parent is not pushed below a basic level of self-support.
Applying through CSA
The Child Support Administration is Maryland's IV-D agency. It's part of the Maryland Department of Human Services. A parent applies for services through MarylandBenefits.gov or by contacting CSA directly. The agency can help establish paternity, set up a new order, or enforce and collect on an order that already exists.
Who hears a Maryland child support case
Maryland circuit courts decide child support matters as part of a divorce, custody case, or standalone support action. They apply the Family Law § 12-204 guidelines to the parents' documented income. CSA works alongside the court system on IV-D cases and can pursue certain administrative steps directly.
Modifying an existing order
A Maryland child support order can be modified if you show a material change in circumstances since the order was entered. This can include a significant change in either parent's income or in the child's needs. Recent Maryland legislation also updated how the guidelines account for a parent's other children. This is sometimes called a multifamily adjustment. It can factor into whether an existing order still matches current law.
Enforcement tools
CSA can withhold income directly from a paying parent's wages. It can also intercept state and federal tax refunds against a parent who falls behind. Maryland's driver's license suspension law for unpaid child support took effect October 1, 2025. This added another enforcement option for cases with significant arrears. A parent who does not comply with a circuit court support order can also be held in contempt of court.
