11. State-Specific Notes

1. Income Shares Model: The District of Columbia uses the Income Shares Model that considers both parents' incomes to estimate what would have been spent on children in an intact household.

2. Age 21 Obligation: D.C. child support continues until the child reaches age 21, which is significantly longer than most jurisdictions.

3. Shared Custody Threshold: The shared custody adjustment applies when the nonresidential parent exercises 128 or more overnights per year (approximately 35% of the year).

4. D.C. OAG Calculator: The D.C. Office of the Attorney General provides an online Child Support Guideline Calculator for preliminary calculations.

5. Imputation of Income: Courts may impute income to a voluntarily unemployed or underemployed parent based on education, training, work history, and available job opportunities.

6. Federal Employment: D.C. has a high proportion of federal employees; government salary and benefits (including locality pay) are included in gross income.
