How is Child Support Calculated in Arizona?

Understanding how child support is calculated in Arizona is crucial for parents going through divorce or establishing paternity. Brown Family Law is proud to serve Arizona families with compassionate divorce and family law services designed to help you protect what matters most – your children’s financial security and well-being.

Arizona uses a specific formula called the Income Shares Model to determine child support amounts, which considers both parents’ incomes and the time each parent spends with the children. This system aims to ensure that children receive the same level of financial support they would have received if their parents remained together.

The Income Shares Model Explained

Arizona’s child support calculation follows the Income Shares Model, established by the Arizona Child Support Guidelines. This approach is based on the principle that children should receive the same proportion of parental income that they would have received if the parents lived together in an intact household.

The model considers the combined income of both parents and determines what portion should be allocated to child support based on economic studies of how much intact families typically spend on their children. This amount is then divided between the parents based on their respective incomes and parenting time arrangements.

The Arizona Supreme Court maintains an online child support calculator that automates these calculations, making it easier for parents and attorneys to determine appropriate support amounts. However, understanding the underlying factors can help you better prepare for your case and ensure accurate calculations.

Key Factors in Arizona Child Support Calculations

Gross Monthly Income forms the foundation of child support calculations. This includes wages, salaries, bonuses, commissions, tips, self-employment income, rental income, investment returns, unemployment benefits, workers’ compensation, disability benefits, and other sources of income. Both parents must provide complete financial disclosure to ensure accurate calculations.

Number of Children directly affects the support amount, as the guidelines include different percentages based on whether you have one, two, three, or more children. The more children involved, the higher the total support obligation, though the per-child amount may decrease slightly.

Parenting Time significantly impacts child support calculations in Arizona. The guidelines recognize that parents who spend more time with their children incur more direct expenses for food, utilities, and other daily costs. The calculation considers overnight stays, with specific formulas for determining parenting time percentages.

Childcare Expenses are added to the basic support amount when parents incur costs for work-related or education-related childcare. These expenses are typically divided between parents in proportion to their incomes.

Health Insurance Premiums for the children are factored into the calculation. The parent who provides health insurance receives credit for the cost of covering the children, which is then allocated between both parents based on their income percentages.

Extraordinary Medical Expenses that exceed the basic amount included in the guidelines may be shared between parents. This includes costs not covered by insurance, such as deductibles, co-pays, and specialized treatments.

Step-by-Step Calculation Process

Step 1: Determine Gross Monthly Income for both parents. This requires gathering documentation such as pay stubs, tax returns, and other income verification. Self-employed parents may need to provide profit and loss statements or business tax returns.

Step 2: Calculate Combined Adjusted Gross Income by adding both parents’ monthly gross incomes and subtracting allowable deductions such as other child support obligations, spousal maintenance payments, and certain other court-ordered payments.

Step 3: Determine Basic Child Support Obligation using the Arizona Child Support Schedule, which provides specific dollar amounts based on combined income and number of children. This schedule reflects economic data about typical child-rearing costs.

Step 4: Calculate Each Parent’s Proportional Share by dividing each parent’s income by the combined income. For example, if one parent earns $4,000 monthly and the other earns $6,000, their shares would be 40% and 60% respectively.

Step 5: Apply Parenting Time Adjustment if the non-custodial parent has the children for significant time. Arizona provides specific adjustments based on the number of overnight stays, which can reduce the support obligation for parents with substantial parenting time.

Step 6: Add Additional Expenses such as childcare costs and health insurance premiums, allocated between parents based on their income percentages.

Step 7: Calculate Final Support Amount by combining the basic obligation with additional expenses and applying any applicable adjustments.

Parenting Time and Support Adjustments

Arizona recognizes that parents who spend more time with their children should receive credit in the child support calculation. The guidelines provide specific adjustments based on parenting time:

Standard Parenting Time (less than 95 days per year) typically results in no adjustment to the basic support calculation. This applies to traditional every-other-weekend and holiday arrangements.

Increased Parenting Time (95-127 days per year) may result in a modest reduction in child support, recognizing the additional direct costs incurred by the non-custodial parent.

Substantial Parenting Time (128-146 days per year) provides more significant adjustments, as the non-custodial parent is providing care for approximately one-third of the year.

Equal or Near-Equal Parenting Time (147+ days per year) can result in substantial adjustments or even eliminate child support obligations, depending on the income differential between parents.

The calculation of parenting time includes overnight stays, with specific rules for counting partial days. A period of 12 hours or more counts as one day, 6-11 hours counts as half a day, and 3-5 hours counts as a quarter day.

Special Circumstances and Deviations

While the Arizona Child Support Guidelines provide a standard calculation method, courts have discretion to deviate from the guidelines in certain circumstances.

High-Income Cases where the combined parental income exceeds the highest amount on the support schedule may require different approaches. Courts may extrapolate from the guidelines or consider the actual needs of the children.

Shared Physical Custody arrangements may require special calculations when children spend substantial time with both parents. The court may need to consider the costs each parent incurs and adjust support accordingly.

Special Needs Children may require additional support beyond the standard guidelines to address extraordinary medical, educational, or care expenses.

Multiple Families situations, where one or both parents have children from other relationships, require careful calculation to ensure fair allocation of support obligations.

Imputed Income may be used when a parent is voluntarily unemployed or underemployed. Courts can assign income based on earning capacity rather than actual earnings in appropriate circumstances.

Modification of Child Support

Child support orders can be modified when there are substantial and continuing changes in circumstances. Arizona law provides specific criteria for when modifications are appropriate.

Significant Income Changes of 15% or more may justify modification, whether due to job loss, promotion, career change, or other factors affecting earning capacity.

Changes in Parenting Time that substantially alter the time children spend with each parent may warrant support modifications to reflect new circumstances.

Changes in Children’s Needs such as new medical conditions, educational requirements, or childcare needs may justify adjustments to support amounts.

Cost of Living Adjustments may be appropriate after significant time has passed since the original order, especially if there have been substantial changes in the cost of raising children.

Enforcement and Collection

Arizona has robust mechanisms for enforcing child support orders and collecting past-due support.

Income Withholding is the primary collection method, where support is automatically deducted from the paying parent’s wages. This applies to most child support orders unless both parents agree to an alternative arrangement.

Asset Seizure may be used for parents who fall behind on support, including bank account garnishment, property liens, and seizure of tax refunds.

License Suspension can affect driver’s licenses, professional licenses, and recreational licenses for parents who are significantly behind on support payments.

Contempt of Court proceedings may result in jail time for parents who willfully refuse to pay court-ordered support.
