In Arkansas, having 50/50 custody does not automatically eliminate child support. Under Administrative Order No. 10, the higher-earning parent typically still pays support to equalize the child's standard of living across both homes. The court calculates a base obligation from combined gross income, then may adjust it when a parent has at least 141 overnights per year.
This guide explains exactly how child support works when parents share equal or near-equal parenting time in Arkansas. It covers the income shares model, the critical 141-overnight threshold, the offset method, add-on expenses, and the 2022 Family Support Chart figures still in effect for 2026. The short version: equal time reduces the math but rarely zeroes it out when incomes differ.

Do You Still Pay Child Support With Joint Custody in Arkansas?
Yes, you can still pay child support with joint custody in Arkansas. Equal 50/50 parenting time does not automatically cancel a support obligation. Under Administrative Order No. 10, the court combines both parents' gross incomes, calculates a base obligation, and the higher earner usually pays the lower earner to balance the child's living standard between two households.
The common myth is that shared physical custody means neither parent pays the other. Arkansas rejects that assumption. The state uses the income shares model, which is built on the principle that a child should receive the same proportion of parental income they would have received if the parents lived together. When one parent earns substantially more, that disparity drives a payment even when both homes house the child for half the year. A judge may decline to order support only in narrow cases — typically when both parents earn similar incomes and split time equally. So the answer to "do I still pay child support with joint custody" in Arkansas depends primarily on the income gap, not the calendar.
How Arkansas Calculates Child Support Under the Income Shares Model
Arkansas calculates child support by combining both parents' gross monthly incomes, finding the Basic Child Support Obligation (BCSO) on the Family Support Chart, then dividing that obligation in proportion to each parent's share of combined income. The model has applied to all orders entered after June 30, 2020, and was revised effective October 6, 2022.
Here is the step-by-step process. First, the court adds both parents' gross incomes — wages, self-employment, and most other sources before taxes and deductions. Second, it looks up the BCSO for that combined income and the number of children on the chart, which covers combined gross income from $900 to $30,000 per month. Third, it calculates each parent's percentage share of the combined income. Fourth, it applies that percentage to the BCSO. For example, if combined monthly gross income is $8,000 and Parent A earns $5,000 (62.5%) while Parent B earns $3,000 (37.5%), Parent A is responsible for 62.5% of the chart amount. In a standard primary-custody case, the non-custodial parent pays their share. The presumptive chart amount is governed by Ark. Code Ann. § 9-12-312 and may only be set aside with a written finding that the chart would be unjust or inappropriate.
The 141-Overnight Rule: When 50/50 Time Adjusts Support
The 141-overnight threshold is the central rule for equal custody child support in Arkansas. Under Administrative Order No. 10, when the paying parent has the child for at least 141 overnights per calendar year — roughly 40% of the time — the court may adjust the support amount downward. This adjustment is discretionary, not automatic, and applies specifically to shared and 50/50 parenting arrangements.
The standard guidelines assume the paying parent has the child fewer than 141 overnights. Once a parent crosses that 141-night line, the guidelines invite a deviation determined case by case. The same discretionary adjustment applies when parents each have the children approximately 50% of the time. In deciding whether and how much to adjust, the court weighs the income disparity between the parties, giving more weight when the income gap is less than 20%, and considers which parent pays the majority of non-duplicated fixed expenses — routine clothing, extracurricular activities, and school supplies. The court can also count significant daytime care that does not include an overnight stay. The takeaway for 50/50 parenting time support in Arkansas: the more equal the time AND the income, the smaller the payment; the larger the income gap, the more support survives the adjustment.
How Equal Custody Child Support Works When Incomes Differ
With equal custody child support in Arkansas, the income gap between parents drives the final number. When both parents earn similar amounts and share time 50/50, a court may order little or no support. When one parent earns significantly more, that parent typically pays the lower earner even with equal parenting time, because the guidelines aim to equalize the child's standard of living across both homes.
Consider two scenarios with one child and a true 50/50 schedule. In the first, both parents earn $4,000 per month. Their incomes are equal, their time is equal, and a judge may reasonably decline to order any support, finding the chart amount unjust under Ark. Code Ann. § 9-12-312. In the second scenario, Parent A earns $7,000 and Parent B earns $3,000. Even at 50/50 time, the income disparity is large — Parent A controls 70% of combined income — so a meaningful monthly payment from Parent A to Parent B typically results, because the income gap exceeds the 20% range that triggers heightened scrutiny. This is why "shared custody child support" in Arkansas can range from zero to several hundred dollars on identical parenting schedules. The variable is the paycheck, not the calendar.
The Offset Method and True Shared Custody
Arkansas uses an offset method in shared and split custody cases. Each parent's theoretical support obligation is calculated as though the other parent were the primary custodian, then the smaller obligation is subtracted from the larger, and the parent with the higher obligation pays the difference. This produces a single net payment rather than two parents paying each other.
The offset method appears most explicitly in split custody — where each parent has sole custody of one or more children — but the underlying logic informs how courts approach 50/50 arrangements. In split custody, a separate Worksheet is completed for each household based on the number of children there, and the obligations are offset against each other. For true shared custody with equal time, courts apply the same netting principle alongside the 141-overnight adjustment: calculate what each parent would owe, then net the figures so only the difference changes hands. The practical effect is that the higher earner pays the lower earner the net amount. The child support 50 50 custody Arkansas calculation therefore rarely produces zero unless incomes are also roughly equal. Parents in this situation should complete the official Arkansas Worksheet and Affidavit of Financial Means, which the court requires in every shared-custody case regardless of the overnight split.
Add-On Expenses: Health Insurance, Childcare, and Medical Costs
Beyond the base obligation, Arkansas adds three categories of expense and splits them proportionally by income: the child's health insurance premium, work-related childcare, and extraordinary out-of-pocket medical costs. These add-ons are divided based on each parent's percentage share of combined gross income, the same percentages used for the base calculation.
The Family Support Chart already builds in ordinary medical spending up to $250 per child per year, so only out-of-pocket medical expenses exceeding $250 per child annually qualify as an add-on. Work-related childcare and the child's share of health insurance premiums are excluded from the base chart and added separately. For a 50/50 custody arrangement, this matters because these costs can rebalance the overall picture: a higher-earning parent who already pays the child's health insurance receives credit for that contribution, which may reduce their net support payment. Each parent's responsibility for add-ons mirrors their income percentage — if Parent A earns 62.5% of combined income, Parent A covers 62.5% of qualifying add-on costs. Document every premium, childcare receipt, and medical bill, because Arkansas courts require proof before allocating these expenses. The add-ons are part of why two families with identical incomes and identical 50/50 schedules can still end up with different net support numbers.
Self-Support Reserve and Minimum Orders for Low-Income Parents
Arkansas protects low-income paying parents through a $900 Self-Support Reserve and a presumptive minimum order of $125 per month. When a paying parent's gross monthly income falls below $900, the court uses only that parent's income — not combined income — and the presumptive minimum of $125 per month applies. Standard add-on expenses are excluded in this low-income range.
The $900 threshold reflects approximately 100% of the federal poverty level for a single individual, adjusted for Arkansas. Its purpose is to ensure that a parent earning very little retains enough income for basic subsistence while still contributing something to the child. When a payor's income falls within the shaded portion of the Family Support Chart, the calculation method shifts: the court bases the obligation on the payor's income alone, and the health insurance, childcare, and extraordinary medical add-ons drop out of the formula. The $125 minimum guarantees that every child receives at least some financial support regardless of how little the paying parent earns. In a 50/50 custody case involving a low-income parent, these provisions can substantially limit or even eliminate a payment, especially when both parents share time equally and neither earns much above the reserve. The chart's full range runs from $900 to $30,000 in combined monthly gross income.
Modifying a 50/50 Custody Child Support Order in Arkansas
Arkansas allows modification of a child support order when there is a material change in circumstances, and a change of more than 20% or more than $100 per month in the calculated amount is presumed material. Either parent may petition the court, and the new amount is recalculated using the current Family Support Chart and Administrative Order No. 10.
Common triggers for modification in shared-custody cases include a significant income change for either parent, a shift in the overnight schedule that crosses the 141-night threshold, a change in childcare or health insurance costs, or the emancipation of a child. If a 50/50 arrangement changes so that one parent now has the children for more time, the support figure can move in either direction depending on the new income shares. To modify, file a petition in the same circuit court that issued the original order, complete an updated Worksheet and Affidavit of Financial Means, and request a hearing. The court applies the presumptive chart amount under Ark. Code Ann. § 9-12-312 and requires a written finding to deviate. Modifications are not retroactive before the filing date, so parents who experience an income drop should file promptly rather than waiting, because support continues to accrue at the old rate until the petition is filed.
