How Alabama Child Support is Calculated

Alabama follows the Income Shares Model under Rule 32 of the Alabama Rules of Judicial Administration. The idea is that a child should receive the same proportion of parental income they would have received if the parents lived together. Both parents contribute — not just the non-custodial parent.

The Step-by-Step Formula

  1. Determine each parent's gross monthly income — wages, self-employment, rental income, benefits, and all other regular income sources before taxes.
  2. Subtract allowable deductions — pre-existing child support paid to another child, and pre-existing alimony actually being paid.
  3. Combine the adjusted incomes and look up the Basic Child Support Obligation from the state's official schedule (Form CS-42).
  4. Calculate each parent's percentage share of the combined income. A parent earning $4,000 of a combined $7,000 has a 57% share.
  5. Add work-related childcare and health insurance costs to the basic obligation. These are split the same proportional way.
  6. Each parent's obligation = total obligation × their income percentage. The non-custodial parent pays their share to the custodial parent.

What Counts as Income in Alabama

Alabama's definition of income is broad. Courts include: wages, salaries, tips, bonuses, commissions, self-employment income, rental income, dividends, interest, Social Security benefits, disability payments, workers' compensation, unemployment benefits, pension and retirement income, and regular gifts. The court can also impute income if a parent is voluntarily unemployed or underemployed.

The 2023 Shared Custody Credit

Before 2023, the standard calculation applied regardless of how much time each parent spent with the child. In 2023, Alabama added a formal credit for shared custody arrangements where each parent has approximately 50% parenting time. Under the updated Rule 32, each parent's obligation is calculated independently as if the other were custodial, and the parent with the higher obligation pays only the difference to the other parent.

Alabama Child Support Ends at Age 19

Unlike most states where support ends at 18, Alabama's age of majority is 19. Support obligations continue until the child's 19th birthday unless the child marries, enters military service, or is otherwise legally emancipated beforehand. There is no automatic extension for college attendance under Alabama law.

Frequently Asked Questions — Alabama Child Support

Alabama uses the Income Shares Model under Rule 32. Both parents' gross monthly incomes are combined, then the Basic Child Support Obligation is found in the state's official schedule. This amount is split between parents proportionally to their incomes. Work-related childcare and the child's health insurance premium are added and split the same way. The non-custodial parent pays their share to the custodial parent.
19. Alabama's age of majority is 19, not 18. Child support continues until the child turns 19 unless they marry, join the military, or are otherwise emancipated earlier. There is no automatic continuation for college — unlike a handful of other states.
In 2023, Alabama added a shared custody credit for arrangements where each parent has approximately 50% time. Each parent's obligation is calculated as if the other were custodial, then the parent with the higher obligation pays the difference. This significantly reduces (or eliminates) support payments in true 50/50 situations compared to the old formula.
Alabama casts a wide net: wages, tips, bonuses, overtime, self-employment income, rental income, dividends, interest, Social Security, disability payments, workers' comp, unemployment benefits, pension income, and regular recurring gifts. Courts can also impute income to a parent they find is voluntarily unemployed or underemployed below their earning capacity.
Yes, if there has been a material change in circumstances — typically meaning the recalculated amount would be at least 10% higher or lower than the current order. File a Petition to Modify with the court that issued the original order. The Alabama DHR automatically reviews orders every three years for cases in the system.
File a petition to modify immediately — don't wait. Job loss is a material change in circumstances. Arrears that accumulate before a modification order is in place are nearly impossible to eliminate. Courts can retroactively adjust only to the date the petition was filed, not before.
Alabama enforces support through income withholding (automatic wage garnishment is standard), federal and state tax refund interception, reporting to credit bureaus for arrears over $1,000, driver's license and professional license suspension, passport denial for arrears over $2,500, and contempt of court proceedings. The Alabama DHR Child Support Services handles enforcement.
$50 per month. Courts generally will not order less than this even if the calculated amount is lower or if the non-custodial parent has very low income. This establishes the legal obligation and keeps the case active for enforcement purposes.
Apply through the Alabama Department of Human Resources (DHR) Child Support Services at childsupport.alabama.gov, or file directly with the court in your county. DHR services are free for families receiving Medicaid or TANF. Other families pay a $25 application fee. DHR can help establish paternity, locate the other parent, set up the order, and handle collections.
