Complete Guide to Child Support in Indiana

Child support ensures that both parents fulfill their financial responsibility to their children, regardless of relationship status. This comprehensive guide explains how Indiana calculates child support, what factors are considered, and how to modify existing orders.

Understanding Indiana's Income Shares Model

Indiana uses the Income Shares Model, which is based on the principle that children should receive the same proportion of parental income they would have received if the parents lived together. This model considers:

Important: Child support in Indiana typically continues until the child turns 19 years old (Indiana's age of emancipation), unless the child is still in high school or has special needs that require extended support.

What Income Is Considered?

Indiana courts consider gross income from virtually all sources, including:

Not included: Means-tested public assistance (TANF, SNAP/food stamps), SSI for disabled individuals, and child support received for other children.

The Parenting Time Credit (PTC)

One of the most significant factors affecting child support is the Parenting Time Credit. This credit acknowledges that when the non-custodial parent spends substantial time with the children, they incur direct expenses during that time.

Pro Tip: Even a difference of 10-20 overnights per year can change your support obligation by hundreds of dollars annually. Track your parenting time precisely using a calendar or custody app.

How the PTC works:

Modifying Child Support Orders

Child support orders are not set in stone. You can request modification when circumstances change substantially. Indiana allows modification under two main scenarios:

1. Substantial and Continuing Change in Circumstances

File for modification anytime if there's a significant, ongoing change:

2. The 20% Rule

If your order is at least 12 months old, you can request modification if recalculating with current information results in at least a 20% change (increase or decrease).

Example: If you currently pay $150/week, but a new calculation shows $185/week (23% increase) or $115/week (23% decrease), you meet the 20% threshold and can file for modification.

Critical: File for modification as soon as circumstances change. Support modifications are not retroactive—they only apply from the date you file the petition forward.

Frequently Asked Questions

Is Indiana's child support formula gender-neutral?

Yes. The formula determines who pays based solely on income and parenting time, not the parent's gender. Either parent may be the paying or receiving parent.

Can I refuse to pay if my ex denies me visitation?

No. Child support and parenting time are separate legal issues. If you're being denied court-ordered parenting time, file a motion to enforce that order. Stopping support payments will result in contempt charges against you.

What if my ex remarries someone wealthy?

Generally, a new spouse's income is not considered in child support calculations. However, in rare cases involving voluntary underemployment, the court may consider overall household resources.

Can we agree to zero child support?

Parents can agree to deviate from guidelines, but a judge must approve it. The judge will only approve if convinced the children's financial needs are met through other documented means.

What happens if I fall behind on payments?

Arrears (past-due support) accrue interest. Indiana can enforce collection through wage garnishment, tax refund intercepts, license suspensions, credit reporting, property liens, passport denial, and in severe cases, criminal prosecution.

How do I calculate income if I'm self-employed?

Start with your gross business income, then deduct only ordinary and necessary business expenses. Personal expenses, depreciation beyond actual cost, and excessive business expenditures are typically not deductible for child support purposes. Be prepared to provide tax returns and profit/loss statements.

Do my other children affect this calculation?

Yes, in two ways: (1) Existing child support orders you pay for other children are deducted from your income before calculating this obligation, and (2) If you have other biological children living with you, the court may consider this, but it's not automatic.
