Child support in Baltimore County runs on Maryland’s statewide Income Shares formula, with local cases administered by the Baltimore County Child Support Administration under the Maryland Department of Human Services. The amount is built from both parents’ incomes, not just the paying parent’s, and the same office that opens your case also handles collection and enforcement if payments stop. What follows is how the number gets set, how to file, how to change an order later, and what the state can do when a parent falls behind.
How the Support Amount Is Calculated
Maryland uses the Income Shares Model under Family Law sections 12-201 through 12-204. The idea is to figure out what the parents earn together, look up a base support amount on the statutory schedule, and divide that amount in proportion to each parent’s share of the combined income.
Income is defined broadly. Wages, salaries, commissions, bonuses, Social Security, pensions and annuities, workers’ compensation, unemployment, disability insurance, dividends, interest, trust income, and alimony received all count. Self-employed parents report gross receipts minus ordinary business expenses. The court has discretion to count severance, capital gains, gifts, and prizes. Means-tested benefits are excluded: Temporary Cash Assistance, Supplemental Security Income, SNAP, and transitional emergency or housing assistance do not count as income for either parent.
Before the schedule is applied, each parent’s income is adjusted downward for child support actually being paid under a preexisting order, alimony actually being paid, and a partial allowance for other children living in that parent’s home to whom the parent owes a legal duty of support. That figure is “adjusted actual income.”
The two adjusted incomes are combined and matched to the basic obligation schedule in section 12-204. The schedule covers combined monthly incomes up to $30,000. Amounts between listed figures are extrapolated upward to the next listed figure. When combined income exceeds $30,000 per month, the court sets the amount at its discretion rather than using the schedule.
Three add-ons get stacked onto the base amount and split in the same income proportions:
- The actual cost of health insurance coverage for the child.
- Work-related or job-search-related childcare costs.
- Extraordinary uninsured medical expenses for the child beyond routine care. The statute sets no specific dollar threshold for what counts as extraordinary.
The result is the non-custodial parent’s monthly obligation.
Shared Custody Changes the Math
When both parents hit at least 25% of overnights, roughly 92 nights per year, Maryland switches to Worksheet B for shared physical custody. If either parent falls below that threshold, Worksheet A and the standard calculation apply.
Under shared custody, the basic support obligation is multiplied by 1.5 to account for the higher cost of maintaining two households for the child. Each parent’s share is then calculated from their proportion of combined income and the actual split of overnights. For overnight percentages between 25% and 30%, a sliding adjustment factor between 0.02 and 0.10 applies based on the exact number of overnights. One ceiling holds in every shared custody case: the final amount cannot exceed what the obligor would owe as a non-custodial parent under the standard worksheet.
Filing a Case in Baltimore County
Pull together recent pay stubs, W-2s, any 1099s, and your most recent federal and state tax returns. You will also need documentation of the monthly cost of health insurance for the child and receipts for work-related childcare, since both feed directly into the support calculation.
Two court financial forms carry the financial picture into the record. Form CC-DR-030 is used when the parents’ combined income is $30,000 or less per year. Form CC-DR-031 is the general financial statement for combined income above $30,000. Both are available through the Maryland Courts website.
The Department of Human Services accepts applications through its myDHR online portal, where Form 980 (Application for Child Support) can be completed and uploaded. You can also request an application by mail or phone, or file in person at the Baltimore County Child Support Administration at 211 Schilling Circle, Suite 102, Hunt Valley, Maryland 21031. The office is open weekdays from 8:30 a.m. to 4:00 p.m. and can be reached at 1-800-332-6347. A nonrefundable $15 application fee applies, and it is owed even if the agency does not succeed in establishing support.
Once the application is in, the other parent has to be formally served before any hearing or administrative order is binding. The court then schedules a hearing to finalize the terms. Timing depends on the docket and on how quickly the other parent can be located and served.
Paternity Comes First for Unmarried Parents
No court can enter a support order without legal paternity. If the parents were married at the birth, Maryland presumes the husband is the father. If they were not, paternity has to be established before anything else happens.
The simpler path is an Affidavit of Parentage, a notarized form both parents sign that adds the other parent’s name to the birth certificate and creates a legal finding of parentage with joint natural guardianship rights. The completed form goes to the Division of Vital Records in Baltimore. This option is only available if the parent who gave birth was not married at any time during the pregnancy.
If paternity is disputed, the Child Support Administration can arrange genetic testing. If testing does not resolve it, a judge decides in a court proceeding.
Changing an Existing Order
Under Family Law section 12-104, either parent can move to modify a support order by showing a material change in circumstances since the order was entered. Job loss, a significant raise, a new disability, and a change in custody are typical examples. Maryland also recognizes incarceration as a potential material change when it substantially reduces the parent’s ability to pay.
Federal rules require states to review orders at least every 36 months after the order was established or last reviewed when a parent requests it, and Maryland offers this review through the Child Support Administration.
One rule traps parents who wait. The court cannot retroactively modify support for any period before the modification motion was filed. If your income dropped six months ago and you only file now, the original amount is still owed for those six months. File as soon as circumstances change.
What Happens When Payments Stop
Maryland’s enforcement tools escalate from automatic payroll collection up to jail.
Income withholding is the default. Every child support order entered since July 1, 1985 operates as an immediate and continuing withholding order on the obligor’s earnings, with the employer deducting support straight from the paycheck.
When arrears accumulate, the Child Support Administration can intercept federal and state tax refunds. Cases are automatically certified for federal tax offset once arrears reach $500 and equal at least twice the monthly order amount. Delinquent accounts can also be reported to credit bureaus.
Under Family Law section 10-119, the agency can notify the Motor Vehicle Administration to suspend the driver’s license of any obligor who is 120 days or more behind. The MVA may issue a work-restricted license in some cases. This tool does not apply to parents whose individual income falls below 250% of the federal poverty guidelines, unless the court previously found the parent voluntarily underemployed or unemployed. Professional and recreational licenses can also be suspended for unpaid support.
At the federal level, arrears over $2,500 trigger passport denial or revocation. The state agency certifies the debt to the U.S. Department of Health and Human Services, which notifies the State Department. No passport issues until the debt is resolved and HHS verifies eligibility.
For persistent non-payment, the agency or the custodial parent can bring contempt proceedings. Civil contempt is remedial: a parent can be jailed but can avoid incarceration by meeting a purge condition, typically paying an amount the court finds the parent currently able to pay. Criminal contempt is punitive, carrying a definite jail sentence for willfully defying the order. Contempt proceedings for unpaid support must be brought within three years of the date each payment became due.
When a Parent Lives Out of State
If one parent is in Baltimore County and the other is elsewhere, the Uniform Interstate Family Support Act controls. Every state participates, and the framework runs on a one-order principle: once a valid support order is entered, that single order governs no matter where either parent moves. The amount does not get re-litigated in a new state.
The federal Office of Child Support Services operates the Federal Parent Locator Service, which Maryland’s Child Support Administration can use to locate non-custodial parents, verify employment, and initiate withholding orders through out-of-state employers without opening a new case from the ground up.
Taxes
Child support is tax-neutral under federal law. The receiving parent does not report it as income, and the paying parent cannot deduct it. When calculating gross income to decide whether a tax return is required, child support received is excluded entirely. This differs from alimony, which has its own rules.
