All 50 states have adopted child support guidelines. Some states use tables that indicate a support amount for different ranges of income, similar to tax tables. Although some states base support on the payor’s income, many states use an income shares model, which is based on the income of both parents. Usually, the parent without the child the majority of the time will pay support, but if both parents share time with the child equally, the parent with the greater income usually pays support. The support may be reduced based upon the amount of time the payor spends with the child. Some states also cap support at a certain income level. If a parent is intentionally not working or is working at less than he or she is capable of earning, the court can “impute income,” which means setting support based upon what the parent is capable of earning rather than actual earnings. States vary on what expenses are included in child support. For example, some states include medical expenses and day care, while other states add those costs on top of the child support.
