Child support is one of the most consequential, and most frequently misunderstood, aspects of family law in Indiana. Whether you are going through a divorce, a paternity case, or a post-decree modification, understanding how child support is calculated can make a significant difference in your ability to plan for the future and advocate for your interests.
Indiana uses an income-shares model for calculating child support, which is designed to approximate the financial support a child would have received if both parents were still living together. The calculation takes into account the income of both parents, along with a number of additional factors including healthcare costs, childcare expenses, and the amount of parenting time each parent exercises. While the Indiana Supreme Court provides a free Child Support Calculator to help parents estimate their obligations, the underlying calculations involve a number of nuances that are easy to get wrong without experienced guidance.
At Ciyou & Associates, P.C., we help parents understand their child support obligations and rights at every stage, from the initial calculation to post-decree modifications. This blog will walk you through how child support is determined in Indiana, what goes into the Child Support Obligation Worksheet, when and how a support order can be modified, and practical steps you can take to protect your interests throughout the process.
Overview of Indiana Child Support Law
In Indiana, both parents have a legal obligation to financially support their children. This obligation exists regardless of whether the parents were ever married, and it continues until the child reaches the age of nineteen or is otherwise emancipated under Indiana law. Child support in Indiana is governed primarily by Indiana Code Title 31, Article 16, and by the Indiana Child Support Rules and Guidelines, which are promulgated by the Indiana Supreme Court and reviewed every four years by the Domestic Relations Committee of the Indiana Judicial Conference.
The Indiana Child Support Guidelines create a rebuttable presumption, meaning that the amount calculated under the guidelines is presumed to be the correct amount of support unless a party demonstrates that deviation is warranted. Courts take this presumption seriously, and any agreed-upon or court-ordered deviation from the guideline amount must be supported by specific, documented reasons explaining why the guideline figure would be unjust or inappropriate in a particular case.
The Income-Shares Model Explained
Indiana's child support system follows what is known as an income-shares model. The fundamental premise of this model is that children should receive the same proportion of parental income that they would have received if the family were still intact. Rather than basing support solely on the income of the non-custodial parent, the income-shares model considers the combined income of both parents and then allocates the total child support obligation between them in proportion to their respective incomes.
This approach recognizes that raising a child is a shared financial responsibility. The custodial parent is presumed to be meeting their share of the obligation through direct expenditures on behalf of the child, housing, food, clothing, and other daily necessities. The non-custodial parent's share is typically satisfied through periodic support payments to the custodial parent.
Determining Weekly Gross Income
The starting point for any child support calculation is determining the weekly gross income of each parent. Under the Indiana Child Support Guidelines, weekly gross income is defined broadly to include the actual weekly gross income of a parent who is employed to full capacity, potential income if the parent is unemployed or underemployed, and the value of in-kind benefits that reduce a parent's living expenses.
Weekly gross income includes income from all sources. This encompasses wages and salaries, but it also includes commissions, bonuses, overtime pay, self-employment income, rental income, interest, dividends, pensions, Social Security benefits (other than survivor benefits paid for children), veterans' benefits, and many other types of income. Notably, the gross income figure for child support purposes may differ from the figure reported on a parent's tax return.
There are certain types of income that are excluded from the calculation. Means-tested public assistance programs, those based on the recipient's income level, are not included in weekly gross income. However, other government benefits, such as Social Security retirement benefits and veterans' pensions, are included.
If a parent is voluntarily unemployed or underemployed, the court may impute income to that parent based on their earning capacity. The court will consider the parent's education, work experience, employment history, and the job market in their area to determine what they could reasonably be earning. It is important to note that Indiana law specifically provides that incarceration may not be treated as voluntary unemployment for purposes of imputing income.
Adjustments to Gross Income
Once weekly gross income has been calculated for each parent, the guidelines permit certain adjustments. These deductions are intended to account for pre-existing financial obligations that reduce the income available for supporting the children at issue. Permitted adjustments include:
Maintenance or alimony payments. If a parent is paying court-ordered spousal maintenance, this amount is deducted from their gross income.
Support for prior-born children. If a parent has a legal duty of support for children from a prior relationship (not including stepchildren) and there is no court order for that support, a deduction may be taken.
Adjustment for subsequent-born or adopted children. A deduction may also be available for children born or adopted after the children at issue.
These adjustments produce each parent's weekly adjusted income, which is the figure used in subsequent steps of the calculation. It is important to apply only those deductions that are authorized by the guidelines, claiming improper deductions can lead to an inaccurate calculation and potential issues in court.
The Child Support Obligation Worksheet
Indiana requires the completion of a Child Support Obligation Worksheet (CSOW) in every case involving child support. The worksheet is a structured form that walks through each step of the calculation and produces a presumptive weekly support amount. Courts, attorneys, and parents all rely on this worksheet, and it must be submitted to the court with any agreement or order involving child support.
The worksheet captures each parent's weekly adjusted income, combines them to arrive at a total weekly adjusted income, and then determines each parent's proportionate share of the combined income. These proportionate shares are applied to the basic child support obligation, the figure derived from the Guideline Schedules, to allocate the total support obligation between the parents. Additional costs such as healthcare premiums and work-related childcare expenses are added to the basic obligation and allocated proportionately as well.
As of January 1, 2024, the Indiana Supreme Court approved updated Child Support Guidelines that include a revised schedule for calculating support amounts, changes related to healthcare cost allocation, and modifications to the parenting time credit calculation. These updated guidelines better approximate actual family spending on children across different income levels, and the Indiana Supreme Court has noted that they are expected to result in an overall increase in support amounts for many families.
The Guideline Schedules for Weekly Support Payments
The Guideline Schedules are essentially lookup tables that provide the basic child support obligation based on the parents' combined weekly adjusted income and the number of children. These schedules are derived from economic data about the actual cost of raising children at various income levels and are periodically updated to reflect current spending patterns.
To use the schedules, you identify the row corresponding to the parents' combined weekly adjusted income and the column corresponding to the number of children. The figure at the intersection represents the total weekly cost of supporting those children at that income level. This figure is then prorated between the parents based on their respective shares of the combined income.
For families with very low income, specifically a combined weekly adjusted income of less than one hundred dollars, the guidelines do not provide a fixed amount and instead require a case-by-case determination. In these situations, the court must carefully balance the child's needs against the obligor's ability to pay without being reduced below a minimum subsistence level.
Additional Costs: Healthcare, Childcare, and Extraordinary Expenses
Beyond the basic child support obligation, the guidelines require that certain additional costs be factored into the calculation. The most common of these are:
Health insurance premiums. The weekly cost of health insurance premiums attributable to the child (not the parent's individual coverage) is added to the basic obligation and allocated between the parents in proportion to their income shares. Every child support order in Indiana must address health insurance coverage.
Uninsured healthcare expenses. The court must also designate how uninsured medical, dental, optical, and other healthcare expenses for the child will be allocated between the parents. These are costs not covered by insurance and can include copays, deductibles, orthodontic treatment, and prescription medications.
Work-related childcare costs. If a parent incurs childcare expenses that are necessary for them to maintain employment, those costs are added to the basic obligation and allocated proportionately.
Extraordinary expenses. In some cases, the court may consider extraordinary educational expenses, special needs costs, or other expenses that significantly exceed typical child-rearing costs. The treatment of these expenses may require the completion of a separate worksheet, and the court has discretion in determining whether to include them in the support calculation.
The Parenting Time Credit
The standard child support calculation assumes that the children reside primarily with one parent, the custodial parent, who bears the direct costs of day-to-day care. However, when the non-custodial parent exercises significant parenting time, they incur their own out-of-pocket expenses for the children during those periods. The Indiana Child Support Guidelines account for this through the parenting time credit.
The parenting time credit applies when the non-custodial parent exercises at least fifty-two overnights per year with the children. The credit increases as the number of overnights increases, with a proportionally larger credit applied as parenting time approaches an equal split. Under the Indiana Parenting Time Guidelines, the standard parenting time schedule results in approximately twenty-seven percent of annual overnights with the non-custodial parent, a figure that serves as a benchmark for the credit calculation.
The parenting time credit recognizes two types of expenses that both parents incur: transferred expenses (costs that shift from one household to the other when the child moves between homes) and duplicated expenses (costs that both households must bear regardless of where the child is on a given day, such as maintaining a bedroom for the child).
It is important to understand that the parenting time credit is not automatic. The judge retains discretion to determine whether applying the credit would jeopardize the custodial parent's ability to adequately support the children. If so, the court may decline to apply the credit or may treat it as a basis for deviation from the guideline amount.
Deviations from the Guidelines
While the guideline calculation creates a rebuttable presumption of the correct support amount, Indiana law recognizes that a rigid formula cannot account for every family's unique circumstances. Courts have the authority to deviate from the guideline amount when the circumstances warrant it, but any deviation must be supported by a written explanation of the reasons.
Under the updated 2024 guidelines, courts must conclude that a proposed deviation is just and appropriate based on the specific facts of the case. The guidelines provide examples of circumstances that may justify deviation, including situations where parents share the child's controlled expenses, where a parent is on work release or a similar correctional program, or where other unusual circumstances make the guideline amount unreasonable.
Parents who agree to a support amount that differs from the guideline calculation must submit their agreement to the court along with the worksheet and a detailed explanation of why the deviation is appropriate. If the agreed-upon amount is less than the guideline amount, the court will scrutinize the reasons especially carefully to ensure that the children's needs will still be adequately met.
Modifying a Child Support Order
Life does not stand still after a child support order is entered, and Indiana law provides a mechanism for modifying support when circumstances change. Under Indiana Code § 31-16-8-1, a child support order may be modified in two primary circumstances.
First, a modification may be granted upon a showing of changed circumstances so substantial and continuing as to make the existing order unreasonable. This standard is intentionally broad and leaves significant discretion to the trial court. Examples of changes that may qualify include job loss, a serious illness or injury, a significant change in parenting time, a substantial change in either parent's income, or the birth of additional children to either parent. Under this standard, there is no mandatory waiting period, the petition can be filed at any time after the original order is entered.
Second, a modification may be sought when the existing support amount differs by more than twenty percent from the amount that would be calculated under the current guidelines, and the order being modified was issued at least twelve months before the petition for modification was filed. This second pathway recognizes that financial circumstances evolve over time and that periodic recalculation may be necessary to ensure that the support amount continues to reflect the family's actual economic situation.
Any modification of child support may be applied retroactively only to the date the petition for modification was filed, not to an earlier date, with very limited exceptions. This makes it critically important to file a petition promptly when circumstances change, rather than waiting and hoping for a retroactive adjustment later.
Conclusion
Child support calculations in Indiana involve a detailed, multi-step process that accounts for the income of both parents, the costs associated with raising children, and the amount of time each parent spends with the children. While the Indiana Child Support Guidelines provide a structured framework for determining support obligations, the application of these guidelines to any particular family's situation requires careful attention to detail and a thorough understanding of the applicable rules.

Frequently Asked Questions
How is child support calculated in Indiana? Indiana uses an income-shares model. Both parents' incomes are combined, and the total child support obligation is determined based on the Guideline Schedules. The obligation is then divided between the parents in proportion to their respective incomes, with adjustments for healthcare costs, childcare, and parenting time.
What income is included in the child support calculation? Weekly gross income includes income from virtually all sources: wages, salaries, commissions, bonuses, self-employment income, rental income, interest, dividends, pensions, Social Security benefits, and more. Means-tested public assistance is excluded.
Can child support be modified after it is ordered? Yes. Child support can be modified if there has been a substantial and continuing change in circumstances that makes the current order unreasonable, or if the existing amount differs by more than twenty percent from the current guideline calculation and the order is at least twelve months old.
What is the parenting time credit? The parenting time credit is an adjustment to the child support calculation that accounts for the out-of-pocket expenses a non-custodial parent incurs when they have the children for at least fifty-two overnights per year. The credit increases as parenting time increases.
When does child support end in Indiana? Child support generally ends when the child turns nineteen years of age or is otherwise emancipated under Indiana law. If the child is incapacitated, support may continue during the period of incapacity or until further order of the court.
Do both parents' incomes matter, or just the non-custodial parent's income? Both parents' incomes matter. Indiana's income-shares model is based on the combined income of both parents, and the total support obligation is allocated proportionately between them.
