How Maryland Calculates Child Support

Maryland calculates child support using the Income Shares Model as defined in Maryland Family Law Code §12-201 through §12-204. Both parents' actual incomes are combined to determine the total support obligation from the state schedule, then each parent's share is allocated proportionally based on their percentage of the combined income.

The calculation begins by determining each parent's actual monthly income from all sources. Maryland also considers potential income for voluntarily impoverished parents. These incomes are combined, and the state schedule is used to find the basic support obligation. Health insurance premiums and childcare costs are added, and adjustments are made for shared custody (when both parents have 35%+ overnights), extraordinary medical expenses, and the self-support reserve of $1,158 per month.

Maryland also imposes a local income tax (county piggyback tax) that varies by jurisdiction, which is factored into the net income calculation. Courts may deviate from guideline amounts when justified by the specific circumstances of the case.

Frequently Asked Questions

How does Maryland calculate child support under the Income Shares model?
Maryland uses the Income Shares Model under Maryland Family Law Code §12-201 through §12-204. Both parents' actual incomes are combined to determine the total support obligation from the state schedule, then each parent's share is allocated proportionally based on their percentage of combined income.
What is the self-support reserve in Maryland?
Maryland maintains a self-support reserve of $1,158 per month (as of 2024). This ensures the paying parent retains enough income to meet their own basic living needs before child support is calculated.
What is voluntary impoverishment in Maryland child support?
Maryland distinguishes between actual income and potential income. If a court finds that a parent is voluntarily unemployed or underemployed (voluntary impoverishment), it may impute income based on the parent's earning capacity, education, skills, and employment history.
Does Maryland consider both parents' income for child support?
Yes. Maryland's Income Shares Model combines both parents' actual incomes to determine the total support obligation. Each parent is responsible for their proportional share based on their income as a percentage of the combined total.
How does shared custody affect Maryland child support?
Maryland provides shared custody adjustments when both parents have 35% or more overnights with the child. The adjustment accounts for the direct expenses each parent incurs during their parenting time and can significantly reduce the support obligation.
