Example Child Support Calculation in District of Columbia

Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.

Step 1: Combined monthly income: $5,000 + $3,000 = $8,000

Step 2: Parent A's income share: $5,000 / $8,000 = 62.5%

Step 3: Look up basic obligation from the guidelines schedule for $8,000 combined income and 2 children.

Step 4: Multiply the basic obligation by Parent A's share (62.5%) to determine their payment.

Frequently Asked Questions About District of Columbia Child Support

How is child support calculated in the District of Columbia?
DC uses the Income Shares model. Both parents' gross incomes are combined, and a basic child support obligation is determined from the schedule (covering combined gross incomes up to $20,000/month). Each parent pays their proportional share based on their percentage of the combined income. Adjustments are made for health insurance, child care, and parenting time.
What income is used for DC child support?
The District of Columbia uses gross income from all sources, including wages, salaries, bonuses, commissions, self-employment income, rental income, investment income, and government benefits. The court may impute income to a parent who is voluntarily underemployed or unemployed.
Does shared custody affect child support in DC?
Yes, DC considers parenting time when calculating child support. When the non-custodial parent has the children for more than 35% of overnights, the court may apply a shared custody adjustment. This adjustment reflects the additional direct costs the non-custodial parent incurs during their parenting time.
Can DC child support orders be modified?
Yes, DC child support orders can be modified if there is a substantial and material change in circumstances. This includes significant changes in either parent's income, changes in custody arrangements, changes in the child's needs, or changes in the cost of health insurance or child care. Either parent can petition the court for a modification.
How long does child support last in DC?
In the District of Columbia, child support generally continues until the child turns 21. This is longer than most states. Support may also continue for adult children with disabilities who are unable to support themselves. DC is one of few jurisdictions where support extends to age 21 rather than 18.
