How Indiana Calculates and Sets Child Support Amounts

Indiana uses a formula based on both parents' income and custody time

Indiana does not have a fixed dollar amount for child support. Instead, the state uses the Income Shares Model, which calculates support based on what percentage of household income each parent would spend on a child if the family were still together. The court takes both parents' gross monthly income, subtracts certain expenses, and divides the obligation between them according to how much time each parent spends with the child.

The actual amount you pay or receive depends on three main factors: each parent's income, how many children are involved, and the custody arrangement. A parent earning $3,000 per month with one child and standard visitation will owe a different amount than a parent earning $5,000 per month with two children and 50/50 custody.

Indiana courts use the Child Support Guidelines, which are updated every four years. The most recent version took effect January 1, 2024. These guidelines include a table that shows the base support obligation for different income levels and numbers of children, but the final order can be adjusted based on the specific circumstances of each case.

Key Takeaways

• Indiana calculates child support by combining both parents' gross monthly income, subtracting certain allowed deductions, and using a percentage-based formula that accounts for custody time.
• The base obligation comes from the state's Child Support Guidelines table, which changes every four years and was last updated January 1, 2024.
• A judge can order more or less than the guideline amount if circumstances like high income, special needs, or significant parenting time differences explore.
• Both parents' income counts toward the calculation, including wages, self-employment income, rental income, and some benefits, but not all income sources are included.
• The amount owed increases with the number of children and decreases as the paying parent's custody time increases.

What income counts toward the calculation

Indiana includes gross income in the child support calculation, which means income before taxes and deductions. This includes W-2 wages, self-employment income, bonuses, commissions, rental income, and income from investments. It also includes some government benefits like unemployment compensation and workers' compensation, though not Supplemental Security Income (SSI) or Temporary information for Needy Families (TANF).

The court subtracts certain expenses from gross income before calculating the obligation. These deductions include federal and state income taxes, Social Security taxes, health insurance premiums for the child, and child care costs directly related to work or education. If a parent is already paying child support for another child, that amount is also deducted.

If a parent is voluntarily unemployed or underemployed, the court may calculate support based on what they could earn rather than what they actually earn. This prevents a parent from avoiding support by deliberately working less or not working at all.

How custody time affects the amount owed

The more time the paying parent spends with the child, the lower the support obligation. Indiana recognizes this by adjusting the calculation based on the percentage of overnights each parent has. A parent with standard visitation (roughly 20% of overnights) owes more than a parent with 50/50 custody.

The adjustment is not dollar-for-dollar with custody time. Instead, the formula reduces the base obligation gradually as parenting time increases. A parent with 40% custody does not pay exactly 60% of the base amount; the reduction is smaller than that because both parents still maintain household expenses even when the child is not present.

If custody changes after the order is entered, either parent can ask the court to modify the support amount. A significant change in custody time — usually defined as a change of at least 10% of overnights — can justify a modification.

The base support table and how courts use it

Indiana's Child Support Guidelines include a table that shows the base monthly obligation for different combined parental incomes and numbers of children. For example, if two parents have a combined monthly income of $4,000 and one child, the table shows a base obligation amount. The court then divides this obligation between the parents based on their individual income percentages.

The table covers combined incomes up to a certain threshold. When combined income exceeds that amount, the court has discretion to set support based on the same percentage used at the threshold, or to adjust it based on the factors listed in Indiana Code 31-16-6-1. This prevents support from becoming unreasonably high in cases where both parents earn substantial income.

The table is not the final order. It is a starting point. A judge can order more or less than the table amount if the case involves factors like a child's special needs, significant disparity in parental income, or a parent's ability to pay.

When a judge can order more or less than the guideline amount

Indiana law allows judges to deviate from the guideline amount if they find that explore the guidelines would be unjust or inappropriate. The statute lists specific factors a court can consider, including the child's special needs or talents, the standard of living the child would have had if the marriage had not been dissolved, and the non-monetary contributions each parent makes to the care and education of the child.

A judge might order more support if one parent has significantly higher income, if the child has medical or educational needs that require extra resources, or if one parent is not exercising the custody time they are may have access to to. A judge might order less if the paying parent has very limited income, if the parents have agreed to a different arrangement, or if the paying parent has substantial custody time not reflected in the guideline calculation.

Any deviation from the guidelines must be documented in the court order, and the judge must explain the reason for the deviation. This creates a record that can be reviewed if either parent later asks to modify the order.

How to find the current guideline amounts

The Indiana Child Support Guidelines are published by the Indiana Supreme Court and are available through the Indiana Judicial Center website. The current guidelines, effective January 1, 2024, include the income table, the list of allowed deductions, and the adjustment percentages for different custody arrangements.

You can also find the guidelines through your local child support enforcement office, which is usually part of your county's prosecutor's office or a separate agency. Many county courts have the guidelines posted on their websites or available in the clerk's office.

If you are working with an attorney, they will have access to the current guidelines and can calculate what the guideline amount would be in your specific situation. If you are representing yourself, you can use the table and the formula to estimate what support might be ordered, though the actual amount will depend on how the court applies the guidelines to your circumstances.

Frequently Asked Questions

Does child support change if one parent loses their job?

Yes, a significant change in income can justify a modification of the child support order. The parent whose income changed must ask the court to modify the order; it does not change automatically. If the income loss is temporary, the court may wait to see if the parent finds new work before modifying. If the loss is permanent, the court will recalculate based on the new income.

What if the parents have 50/50 custody?

Even with equal custody time, one parent usually still owes support to the other if their income is significantly higher. The adjustment for custody time reduces the obligation, but it does not eliminate it. The parent with higher income pays a portion of the base obligation to the parent with lower income.

Does child support include money for activities, school, or medical expenses?

The base child support amount covers ordinary living expenses like food, housing, and utilities. Extraordinary expenses like private school tuition, orthodontics, or sports activities can be addressed separately in the court order. Some orders require both parents to split these costs, while others assign them to one parent or include them in the support amount.

Can child support be modified if circumstances change?

Yes, either parent can ask the court to modify support if there has been a substantial and continuing change in circumstances. This includes changes in income, custody time, health insurance costs, or the child's needs. The parent requesting the modification must file a petition with the court.

What happens if a parent does not pay child support?

Indiana's child support enforcement office can take action to collect unpaid support, including wage garnishment, tax refund intercept, suspension of professional licenses, and contempt of court proceedings. The enforcement process is handled by the county prosecutor's office or a dedicated child support agency.
