Maryland child support payments typically range from $50 to $2,847 or more per month, calculated using the state's income shares model under Maryland Family Law § 12-204. The exact amount depends on combined parental income, number of children, custody arrangement, and additional expenses like health insurance and childcare. For a combined monthly income of $15,000 with two children under primary custody, the basic support obligation is approximately $2,098 per month, divided proportionally between parents based on their income percentages.

How Maryland Calculates Child Support Payments
Maryland courts calculate child support using the income shares model, which assumes children should receive the same proportion of parental income they would have received if the family remained intact. Under Maryland Family Law § 12-202, the guidelines create a rebuttable presumption that the calculated amount is correct, meaning courts must follow the formula unless specific circumstances justify deviation.
The calculation process follows these steps:
- Determine each parent's gross monthly income from all sources (wages, bonuses, commissions, rental income, investments)
- Subtract preexisting child support or alimony obligations for other children
- Add or subtract alimony from the current case
- Combine both parents' adjusted actual incomes
- Look up the basic support obligation on the schedule in Maryland Family Law § 12-204
- Add work-related childcare costs and health insurance premiums
- Divide the total obligation proportionally based on each parent's share of combined income
For parents earning minimum wage or facing financial hardship, the self-support reserve ensures the paying parent retains at least 110% of the federal poverty level for an individual after paying support.
Maryland Child Support Schedule: 2026 Payment Amounts
The schedule of basic child support obligations under Maryland Family Law § 12-204 provides specific dollar amounts based on combined adjusted parental income. Below is a representative sample from the official guidelines:
| Combined Monthly Income | 1 Child | 2 Children | 3 Children | 4 Children |
|---|---|---|---|---|
| $1,200 | $50* | $55* | $57* | $58* |
| $2,000 | $403 | $591 | $658* | $667* |
| $5,000 | $897 | $1,316 | $1,584 | $1,784 |
| $10,000 | $1,361 | $1,885 | $2,236 | $2,495 |
| $15,000 | $1,569 | $2,098 | $2,472 | $2,752 |
| $20,000 | $1,752 | $2,313 | $2,716 | $3,017 |
| $30,000 | $2,112 | $2,847 | $3,362 | $3,740 |
*Asterisked amounts indicate adjustments made under the self-support reserve to protect low-income parents.
When combined monthly income exceeds $30,000, courts have discretion to set support amounts based on the children's actual needs rather than strictly following the guidelines. Between schedule amounts, courts extrapolate to determine the appropriate obligation.
How Much Is Child Support in Maryland: Real-World Examples
Understanding how much child support costs in Maryland requires examining typical scenarios with actual numbers.
Consider Parent A earning $6,000 monthly and Parent B earning $4,000 monthly with two children in primary custody with Parent B. The combined adjusted income of $10,000 yields a basic support obligation of $1,885 per month. Parent A earns 60% of the combined income ($6,000 / $10,000), so Parent A's share equals $1,131 monthly ($1,885 x 0.60). After adding Parent A's proportional share of $400 monthly childcare costs ($240) and $200 monthly health insurance ($120), the total child support payment from Parent A to Parent B equals approximately $1,491 per month.
For a higher-income family where Parent A earns $12,000 monthly and Parent B earns $8,000 monthly with three children, the combined income of $20,000 generates a basic obligation of $2,716. Parent A's 60% share equals $1,630 monthly before adding childcare and insurance contributions.
Shared Custody Child Support Calculations
Maryland defines shared physical custody as each parent having the children overnight for at least 92 nights per year, representing 25% of annual overnights. Under Maryland Family Law § 12-204, shared custody arrangements use Worksheet B instead of Worksheet A, resulting in adjusted support calculations that account for both parents' direct expenditures during their parenting time.
The shared custody formula multiplies the basic support obligation by 1.5 to account for duplicated household expenses, then adjusts based on each parent's percentage of overnights and income. This calculation typically results in lower support payments compared to primary custody arrangements because the higher-earning parent already covers expenses during their custodial time.
For parents with custody between 25% and 35% of overnights (92 to 128 nights annually), Maryland applies a transitional formula that gradually phases between the primary custody and shared custody calculations, preventing drastic payment changes as custody arrangements evolve.
New 2026 Multifamily Adjustment Rules
Effective October 1, 2025, Maryland implemented the Multifamily Adjustment, which significantly impacts child support calculations for parents supporting children from multiple relationships. Under this new provision, parents may deduct 75% of the theoretical child support obligation for qualifying children already living in their household.
Three conditions must be satisfied to claim this adjustment:
- The parent must have a legal duty to support the child through birth or adoption
- The child must reside with the parent for more than 92 overnights per year
- No existing court order requires the parent to pay support for that child
This adjustment reduces the parent's adjusted actual income before calculating support for other children, potentially lowering payments by hundreds of dollars monthly for parents with children from prior relationships living in their home.
How Long Child Support Lasts in Maryland
Maryland child support obligations continue until the child reaches age 18, dies, or becomes emancipated. However, if a child remains enrolled in high school past their 18th birthday, support continues until the child graduates or turns 19, whichever occurs first. For example, a child turning 18 in October but graduating the following June would receive support through graduation.
Maryland courts do not order parents to pay child support for college expenses, unlike some other states. However, parents may voluntarily agree to contribute to higher education costs in their marital settlement agreement or custody order, and courts will enforce such agreements.
Emancipation ends support obligations before age 18 when a child becomes legally independent through marriage, military enlistment, or demonstrated financial self-sufficiency. Parents seeking to terminate support based on emancipation must file a motion and present evidence to the court rather than simply stopping payments.
Modifying Child Support in Maryland
Under Maryland Family Law § 12-104, either parent may request a child support modification by demonstrating a material change of circumstance. Courts generally consider a change material when it represents at least a 25% difference in income or expenses and is relevant to the child's support needs.
Common grounds for modification include:
- Significant income changes (job loss, promotion, disability)
- Changes to custody arrangements affecting parenting time
- New childcare or educational expenses
- Medical conditions creating extraordinary healthcare costs
- Cost of living adjustments
- Incarceration of the paying parent (as of October 2024)
Importantly, modifications apply only from the date of filing forward. Under Maryland Family Law § 12-104(b), courts cannot retroactively adjust support to before the modification motion was filed. If circumstances change in March but no motion is filed until August, any adjustment begins in August, not March.
Child Support Enforcement in Maryland
The Maryland Child Support Administration (CSA) enforces support orders through multiple automated mechanisms. Wage withholding applies to most orders, with employers required to remit payments within seven business days of paying wages. Employers who fail to withhold or remit payments face liability for the full amount plus potential penalties.
Federal and state law limit wage garnishment to protect paying parents from excessive deductions:
| Situation | Maximum Garnishment |
|---|---|
| Supporting current family, current on payments | 50% of disposable earnings |
| No other dependents, current on payments | 60% of disposable earnings |
| Supporting current family, 12+ weeks behind | 55% of disposable earnings |
| No other dependents, 12+ weeks behind | 65% of disposable earnings |
Beyond wage garnishment, Maryland enforcement tools include federal and state tax refund intercepts, lottery winnings intercepts, credit bureau reporting, bank account garnishment, passport denial for arrears exceeding $2,500, driver's license suspension for 60+ days non-compliance, and occupational license suspension.
In fiscal year 2024, Maryland collected a record $549 million in child support payments, demonstrating the effectiveness of these enforcement mechanisms.
Filing Fees and Court Costs
Filing fees for child support matters in Maryland vary by county but generally range from $150 to $200 for initial petitions. As of March 2026, verify exact fees with your local Circuit Court clerk. Parents unable to afford filing fees may request a waiver if household income falls at or below 125% of federal poverty guidelines.
The Maryland Child Support Administration provides free services for establishing, modifying, and enforcing support orders when either parent applies for assistance. The CSA Customer Care Center (1-800-332-6347) handles general questions and payment information at no charge.
Maryland Residency Requirements for Child Support
Under Maryland Family Law § 7-101, at least one parent must reside in Maryland to file for child support through state courts. If the grounds for the action arose outside Maryland, the filing parent must have resided in the state for at least six months before filing. Unlike some states, Maryland does not require residency in a specific county, only within the state.
For interstate cases, Maryland participates in the Uniform Interstate Family Support Act (UIFSA), allowing coordination with other states' child support agencies to establish and enforce orders across state lines.
Frequently Asked Questions
How much is child support in Maryland for one child?
Child support for one child in Maryland ranges from $50 to over $2,000 monthly depending on combined parental income. At $5,000 combined monthly income, the basic obligation is $897; at $10,000 combined income, it rises to $1,361. The paying parent's share depends on their percentage of combined income plus additional amounts for childcare and health insurance.
Can Maryland child support be higher than the guidelines amount?
Yes, courts may order above-guidelines support when combined parental income exceeds $30,000 monthly or when children have extraordinary needs. Under Maryland Family Law § 12-202, judges must document reasons for deviating from guidelines, including how the deviation serves the child's best interests.
Does shared custody reduce child support in Maryland?
Shared custody typically reduces child support payments because both parents directly cover expenses during their parenting time. When each parent has the child at least 92 overnights annually (25%), Maryland uses Worksheet B, which accounts for duplicated household costs and each parent's actual caregiving expenditures.
What income counts for Maryland child support calculations?
Maryland counts all income sources including wages, salaries, commissions, bonuses, tips, rental income, investment returns, Social Security benefits, unemployment compensation, workers' compensation, and pension distributions. Courts may impute income to voluntarily unemployed or underemployed parents based on earning capacity.
How do I modify child support in Maryland?
File a motion for modification in the Circuit Court that issued the original order, demonstrating a material change of circumstance such as 25% or greater income change, custody modifications, or new extraordinary expenses. Modifications take effect from the filing date forward; Maryland courts cannot retroactively adjust support before the motion was filed.
What happens if I do not pay child support in Maryland?
Non-payment triggers enforcement actions including wage garnishment up to 65% of disposable earnings, tax refund and lottery intercepts, credit reporting, bank account garnishment, passport denial for arrears over $2,500, driver's license suspension after 60 days non-compliance, and potential contempt of court charges with jail time.
Does Maryland require child support for college students?
No, Maryland does not legally require parents to pay child support for children attending college after age 18. Support ends at 18 or 19 if the child remains in high school. However, parents may voluntarily agree to college expense contributions in separation agreements, which courts will enforce.
How is child support calculated with multiple children from different relationships?
As of October 2025, Maryland's new Multifamily Adjustment allows parents to deduct 75% of the theoretical support obligation for qualifying children living in their household from other relationships. This reduces adjusted income before calculating support for children from the current case, potentially lowering payments significantly.
Can child support be waived in Maryland?
Parents cannot waive child support because it belongs to the child, not the parents. Even when custodial parents agree to forgo support, courts may reject such agreements if they do not serve the child's best interests. Courts can establish support orders regardless of parental agreements.
Where do I file for child support in Maryland?
File in the Circuit Court of the county where either parent resides, or where the defendant is regularly employed or has a place of business. The Maryland Child Support Administration also accepts applications for establishing support orders at no cost through their Customer Care Center at 1-800-332-6347.
