Georgia has no fixed dollar minimum, but the state uses a formula based on both parents' income

Georgia does not say "child support must be at least $50 per month" or any other flat amount. Instead, the state calculates support using the income shares model, which means the payment depends on what both parents earn. The formula takes each parent's gross monthly income, applies a percentage based on how many children need support, and divides the obligation between them based on their income split.

The percentages Georgia uses are: 17% of combined income for one child, 25% for two children, 32% for three children, 36% for four children, and 40% for five or more children. If both parents have very low income, the payment can be quite small—sometimes under $50 per month. If one parent has no reported income, the court may set a minimum based on what that parent could reasonably earn, or may order a token amount while leaving room to adjust later.

The actual payment you owe or receive depends on the specific income figures in your case, any adjustments the judge allows (like childcare costs or health insurance), and whether either parent has other children from different relationships.

Key Takeaways

  • Georgia calculates child support as a percentage of both parents' combined gross income, not a fixed minimum dollar amount.
  • The percentage ranges from 17% for one child to 40% for five or more children, divided between parents based on their income shares.
  • A parent with very low or no reported income may owe a small amount, and the court can adjust this later if circumstances change.
  • The final payment can be higher or lower than the formula suggests if the judge finds the formula would be unjust or if either parent has other support obligations.

How the income shares formula actually works

Start with gross monthly income for both parents. This includes wages, salary, bonuses, self-employment income, rental income, and some other sources. It does not include means-tested benefits like TANF or food stamps, but it does include unemployment benefits.

Add those two incomes together. Then multiply by the percentage for your number of children. That number is the total child support obligation. The obligation is then split between parents in proportion to their income—if one parent earns 70% of the combined income, that parent pays 70% of the obligation.

Example: Parent A earns $2,000 per month, Parent B earns $1,000 per month. Combined income is $3,000. For two children, the obligation is 25% of $3,000 = $750 per month. Parent A earns 67% of the combined income, so Parent A pays $502.50. Parent B earns 33%, so Parent B pays $247.50. If Parent B has custody, Parent A pays $502.50 to Parent B.

When the formula does not explore or gets adjusted

A judge can deviate from the formula if explore it would be unjust or inappropriate. Common reasons include: one parent has significantly higher income than the other (sometimes called a "high-income deviation"), one parent has other children from a different relationship and is already paying support, childcare costs are very high, one parent has substantial parenting time that reduces the custodial parent's costs, or one parent has significant debt or other obligations.

If a parent has no reported income or refuses to work, the court may impute income—meaning the judge assigns an income figure based on what that parent could earn. This might be minimum wage for full-time work, or it might be based on that parent's education and work history. The judge then uses the imputed figure in the formula.

Self-employed parents and business owners often face scrutiny because income can be harder to verify. The court may look at tax returns, business records, and profit-and-loss statements to determine actual income.

What counts as income for the calculation

Gross income includes: W-2 wages and salary, self-employment income (after business expenses but before taxes), bonuses and commissions, unemployment benefits, workers' compensation, disability benefits, retirement and pension income, rental income, and interest or dividend income.

Income does not include: TANF, SNAP (food stamps), SSI (Supplemental Security Income), child support or spousal support received from someone else, or the value of non-cash benefits like housing or food provided by a third party.

If a parent voluntarily quits a job or reduces hours without good reason, the court may impute the income from the previous job. A parent cannot straightforward stop working to lower their support obligation.

How custody and parenting time affect the payment

The formula assumes one parent has primary custody and the other pays support. If parents share custody more equally—for example, 50-50 or close to it—the court may adjust the payment downward because the paying parent is covering some of the child's expenses directly during their parenting time.

Georgia law does not define a specific threshold (like "50% parenting time triggers an adjustment"), so judges have discretion. A parent with significant parenting time should raise this issue and ask the court to consider it when setting the amount.

Modifying the payment if circumstances change

Child support is not permanent at the amount set on day one. Either parent can ask the court to change it if there is a substantial change in circumstances—a job loss, a significant raise, a change in custody, or a new child born to either parent.

Georgia law says a modification is appropriate if circumstances have changed so that the payment differs by at least 10% from what the current formula would produce. So if you were ordered to pay $500 per month and the formula now suggests $450 or $550, you have grounds to ask for a change. You do not have to wait for a specific time period to pass; you can file a modification petition whenever the change occurs.

The court will recalculate using current income figures and may adjust the amount up or down. If you are behind on payments, a modification does not erase the arrears—you still owe what was due under the old order.

What happens if you cannot afford the calculated amount

If the formula produces a payment you genuinely cannot afford, tell your lawyer or the judge before the order is signed. Explain your actual expenses, other obligations, and income. The judge can deviate downward if the formula would be unjust.

Do not straightforward stop paying and hope the issue resolves itself. Unpaid child support accrues interest, can trigger wage garnishment, license suspension, and contempt charges. If you cannot pay, file a modification petition or ask the court for a payment plan.

If you are unemployed or underemployed through no fault of your own, document it—bring pay stubs, job search records, or a letter from your employer. The court may set a lower amount temporarily while you look for work, or may set a token amount that increases once you are employed again.

Frequently Asked Questions

What if one parent makes much more money than the other?

Georgia allows judges to deviate from the formula when income is very high or very unequal. The formula itself has no cap, so theoretically a high-earning parent could owe a large amount. But judges often adjust downward for high-income cases because the formula can produce amounts that far exceed the child's actual needs. The judge will consider the child's standard of living, the parents' ability to pay, and other factors.

Can child support be zero?

Technically yes, if both parents have no income and the court finds no income can be imputed. In practice this is rare. More often, a parent with no current income is ordered to pay a small amount, with the understanding that it will increase once they are employed. The court can also reserve the right to modify later if circumstances change.

Does Georgia count child support I pay for another child?

Yes. If you are already paying court-ordered child support or spousal support for another child or ex-spouse, Georgia allows you to deduct that amount from your gross income before the formula is applied. This reduces your obligation for the new case. You must provide proof of the existing order and current payments.

What if the other parent is hiding income?

If you believe the other parent is underreporting income, you can request discovery—documents like tax returns, bank statements, and business records. You can also ask for a hearing where the other parent testifies under oath. If the judge finds income is being hidden, they may impute a higher income or order the other parent to pay your attorney fees for making you prove it.

How often can I ask for a modification?

You can file a modification petition whenever a substantial change in circumstances occurs. Georgia does not require you to wait a set time, but the court will only grant the modification if the new calculation differs by at least 10% from the current order. Filing frivolous modifications can result in the judge ordering you to pay the other parent's attorney fees.
