Nebraska Worksheet 4 — Number of Children Calculation (DC 6:1(4)) is a form used to calculate the number of children a Nebraska taxpayer has for the purpose of determining the correct amount of state income tax each parent must pay. This form is used when both parents are claiming a dependent child on their Nebraska state income tax return. There are two types of Nebraska Worksheet 4 — Number of Children Calculation (DC 6:1(4)): (1) Worksheet 4-1, which is used for calculating the number of children when one or both parents are claiming a dependent child, and (2) Worksheet 4-2, which is used for calculating the number of children when both parents are claiming a dependent child. The form requires the taxpayer to provide information such as the name and Social Security number of the parents, the total number of dependent children in the household, and the tax year for which the form is needed. Depending on the information provided, the form will then calculate the total number of children the taxpayer has and the tax liability associated with each parent.
