How Georgia Child Support Works

Georgia uses the Income Shares Model under Official Code of Georgia Annotated §19-6-15, enacted in 2007. Like Ohio and most states, Georgia combines both parents' adjusted gross incomes to determine what two married parents would typically spend on their children, then apportions that amount based on each parent's income share.

Georgia Adjusted Gross Income

Georgia uses "adjusted gross income" (AGI), which begins with gross income and subtracts: pre-existing child support orders being paid, other qualified alimony payments, and support for other children living with the parent. This differs from some states that use net income after taxes.

Deviations Under OCGA §19-6-15

Georgia courts may deviate from the presumptive amount when deviation is in the best interests of the child. Common grounds for deviation include:

Parenting time: When NCP has 35%+ overnights (128+ per year), courts can apply a reduction
Travel expenses: Extraordinary transportation costs for parenting time
Extraordinary educational expenses: Private school, tutoring
Voluntary unemployment / underemployment: Courts can impute income
Extraordinary medical expenses not covered by insurance

Combined AGI = NCP Adjusted Gross + CP Adjusted Gross
Basic Obligation = GA Schedule Lookup (Combined AGI, # Children)
NCP Share = NCP AGI ÷ Combined AGI
NCP Support = Basic Obligation × NCP Share + Deviations (Health, Childcare, Travel)

Worked Example

NCP earns $5,800/mo AGI. Custodial parent earns $3,400/mo AGI. Two children. Standard parenting time.

Frequently Asked Questions

What is adjusted gross income in Georgia child support? ▼

Georgia's adjusted gross income starts with gross income from all sources (wages, self-employment, bonuses, interest, Social Security, etc.) and then subtracts: (1) pre-existing child support orders the parent is actually paying, (2) qualified alimony being paid under pre-2019 divorce orders, and (3) support for other children living in the parent's home. Imputed income may be used if a parent is voluntarily unemployed or underemployed.

When does the parenting time deviation apply in Georgia? ▼

Georgia OCGA §19-6-15(i)(2)(J) allows a parenting time deviation when the non-custodial parent exercises 35% or more of the parenting time (about 128 overnights per year). Georgia uses a specific deviation formula that accounts for the actual costs incurred during the NCP's parenting time. Unlike some states, this deviation is not automatic — the parent must request it and demonstrate it is in the child's best interests.

Does Georgia impute income to stay-at-home parents? ▼

Yes. Georgia courts can impute income to a parent who is voluntarily unemployed or underemployed without reasonable cause. Imputed income is based on the parent's earning capacity — their education, work history, job skills, and available jobs in their area. Courts consider whether a parent voluntarily left a job, whether unemployment is temporary, and the needs of minor children. Imputation can significantly increase the combined income and thus the basic obligation.

How often can Georgia child support be modified? ▼

Georgia allows modification when there has been a substantial change in either parent's income or financial status, or in the needs of the child. A difference of at least 15% between the current order and the newly calculated amount is generally considered a substantial change. There is no mandatory waiting period between modifications, but courts can consider the frequency of modification requests. Georgia OCGA §19-6-15(k) governs the modification procedure.

What is the self-support reserve in Georgia? ▼

Georgia maintains a self-support reserve to ensure the paying parent retains enough income to meet their own basic needs. If the calculated support would leave the NCP with less than the federal poverty level for one person (approximately $1,215/month), the court may deviate downward. This prevents support orders from being so high they make compliance impossible. Courts still expect some payment even at very low incomes.

When to Consult a Georgia Family Law Attorney

This calculator produces estimates. Consult a licensed Georgia attorney if your case involves: parenting time near the 35% deviation threshold, SB 454 parenting time adjustments effective 2026, self-employment or imputed income disputes, voluntary unemployment claims, or modification requests based on 15%+ income change under OCGA §19-6-15(k).
