Arizona requires all child support payments to flow through the Arizona Support Payment Clearinghouse, the state disbursement unit established under A.R.S. § 46-441. Parents can pay child support in Arizona through six primary methods: automatic wage withholding (the default), iPayOnline bank transfers, phone payments via 1-888-585-7942, retail cash payments at CVS, Family Dollar, or 7-Eleven locations, money orders mailed to the Clearinghouse, or direct payments through the Clerk of Court. Processing time for payments averages 2-3 weeks, and unpaid support accrues interest at 10% per year under A.R.S. § 25-510.

Understanding How to Pay Child Support in Arizona
Arizona law mandates that all child support payments pass through the Support Payment Clearinghouse rather than being paid directly between parents. Under A.R.S. § 46-441, this centralized system tracks every payment, calculates arrears, and provides official payment histories that courts rely upon for enforcement proceedings. The Clearinghouse processed payments for over 300,000 Arizona child support cases in 2025, disbursing funds to custodial parents within 48 hours of receipt for electronic payments.
The Arizona Division of Child Support Services (DCSS) administers the child support payment portal and enforcement mechanisms. Parents who pay child support in Arizona must understand that the state distinguishes between IV-D cases (those receiving state enforcement services) and Non-IV-D cases (privately maintained orders). This distinction affects which payment methods are available and how payments are processed through the system.
Before selecting a payment method, parents should verify their case type by contacting DCSS at 602-252-4045 or checking their court order. IV-D cases receive full state enforcement services including wage withholding setup, while Non-IV-D cases may require additional coordination with the Clerk of Court.
Wage Withholding: The Default Child Support Payment Method
Wage withholding serves as Arizona's primary child support collection method, automatically deducting payments from the paying parent's paycheck before funds reach their bank account. Under A.R.S. § 25-504, all Arizona child support orders issued since 1988 include automatic wage withholding provisions, requiring employers to remit payments directly to the Support Payment Clearinghouse. Employers must begin withholding within 14 working days of receiving an Income Withholding Order and must transmit withheld amounts within 2 business days of each pay date.
Child support withholding takes priority over all other garnishments under Arizona law. Even if another creditor served a wage garnishment order first, child support must be deducted before any other legal process. The maximum withholding amount equals 50% of the employee's disposable earnings, protecting parents from excessive garnishment while ensuring children receive adequate support.
Employers face penalties for non-compliance with wage withholding orders. Under A.R.S. § 25-513, employers who fail to withhold or remit payments may be held liable for the amounts they should have withheld, plus penalties. Arizona provides employers with free electronic payment options through the Employer Portal at the DCSS website, streamlining compliance with Income Withholding Orders.
Self-employed parents and business owners cannot use wage withholding and must establish alternative payment arrangements. These parents typically use iPayOnline scheduled payments or retail cash payments to maintain consistent payment schedules without employer involvement.
iPayOnline: Arizona's Child Support Payment Portal
Arizona's iPayOnline system provides free, secure electronic child support payments directly from bank accounts at ipayonline.azsdu.net. Parents can schedule recurring automatic payments or make one-time payments through this child support payment portal, which sources funds via ACH bank transfers with no convenience fees. Registration requires the parent's ATLAS case number, Social Security number, and bank account information.
The iPayOnline portal offers several advantages over other payment methods. Parents can view payment history, schedule payments up to 365 days in advance, set up automatic recurring payments aligned with pay schedules, and receive email confirmations for each transaction. Customer service for iPayOnline is available at 602-843-1230 or toll-free at 844-518-4385 for registration assistance and technical support.
Processing time for iPayOnline payments typically ranges from 3-5 business days, faster than mailed payments but slower than wage withholding direct deposits. Parents should account for this processing time when scheduling payments to avoid accidental late payments that could trigger interest charges or enforcement actions.
To register for iPayOnline, parents need their court order case number (ATLAS number), valid bank account with routing number, and email address for confirmations. The system does not accept credit or debit card payments—only ACH bank transfers from checking or savings accounts.
Phone Payments and Payment Gateway Options
Arizona offers phone payment options through the State of Arizona Child Support Payment Gateway at 1-888-585-7942. This service allows parents to make child support payments using debit cards, credit cards (Visa, MasterCard, Discover), or bank account information over the phone. Convenience fees may apply for card payments, though exact amounts should be verified at the time of payment.
The DCSS Customer Service line at 602-252-4045 (Maricopa County) or 1-800-882-4151 (toll-free statewide) provides assistance Monday through Friday from 7:00 a.m. to 5:30 p.m. Staff can help parents understand their payment options, verify account balances, and troubleshoot payment issues. Parents should have their ATLAS number ready when calling to expedite service.
Phone payments process within 3-5 business days for bank account payments and 1-3 business days for card payments. While slightly slower than direct deposit from wage withholding, phone payments offer flexibility for parents with irregular income or those needing to make catch-up payments outside their normal schedule.
Retail Cash Payments: CVS, Family Dollar, and 7-Eleven
Arizona partners with PayInCashNow to offer retail cash payments for child support at CVS, Family Dollar, and 7-Eleven locations statewide. This cash-only option requires parents to visit PayInCashNow.com first to generate a personalized DCSS PaySlip with a unique barcode. The convenience fee is $2.49 per transaction for non-DCSS payments.
To make a retail payment, parents must print or display their PaySlip barcode on a mobile device, bring cash (exact amount or more) to a participating retailer, and present the barcode to the cashier. Payments typically post within 24-48 hours, making this one of the faster non-wage-withholding options. Receipts should be retained as proof of payment.
Retail payments work well for parents who prefer cash transactions, those without bank accounts, or parents making irregular catch-up payments. The $2.49 fee per transaction can add up for weekly payments, so parents making regular payments should consider setting up iPayOnline or wage withholding to avoid recurring fees.
Mailing Payments to the Support Payment Clearinghouse
Parents can mail payments to the Arizona Support Payment Clearinghouse at PO Box 52107, Phoenix, Arizona 85072-2107. Payments must be made payable to "Support Clearinghouse" and must include the parent's ATLAS case number on the check or money order. Personal checks, certified checks, cashier's checks, and money orders are all accepted with no convenience fees beyond postage.
For overnight or express payments requiring faster delivery, parents can send payments to: Arizona Department of Economic Security, DCSS – State Disbursement Unit, 1789 W. Jefferson, Mail Drop 7221, Phoenix, AZ 85007. Standard USPS rates apply for overnight delivery, and tracking is recommended for high-value payments.
Mailed payments require 2-3 weeks for processing, the longest processing time of any payment method. Parents relying on mailed payments should send them well in advance of due dates to avoid late payment issues. For time-sensitive payments, iPayOnline or phone payments offer faster processing alternatives.
Direct Deposit for Child Support Recipients
Parents receiving child support can elect direct deposit to have payments automatically deposited into a personal checking or savings account. The Authorization for Direct Deposit form is available from DCSS or local Clerk of Court offices. Parents can also set up direct deposit by calling 602-372-5375 or mailing Form CSE-1129A to: Arizona State Disbursement Unit, Electronic Payment Authorization Unit, PO Box 36626, Phoenix, AZ 85067-6626.
Direct deposit setup requires 4-6 weeks for processing. During this transition period, parents continue receiving payments via check. Once activated, direct deposit provides the fastest access to child support funds, with payments typically available within 24-48 hours of Clearinghouse receipt. All child support and spousal maintenance payments consolidate into a single designated account.
The Way2Go Electronic Payment Card serves as an alternative to direct deposit for parents who prefer debit card access or lack traditional bank accounts. This MasterCard-branded debit card is issued by Comerica Bank with no enrollment fee. If parents don't elect direct deposit or Way2Go within two live check mailings, the Clearinghouse automatically issues a Way2Go card to the address on file. The card works at ATMs worldwide and anywhere MasterCard debit cards are accepted.
Child Support Arrears and Interest Calculations
Unpaid child support in Arizona accrues interest at 10% per year under A.R.S. § 25-510. This rate applies as simple interest, meaning interest accumulates only on the principal balance and does not compound on previously accrued interest. Interest begins accruing at the end of the month following the month in which payment was due—a missed January payment starts accruing interest on March 1.
The Arizona eCalc tool at extranet.azdes.gov/ecalc provides official arrears calculations for Arizona child support cases. This web-based calculator, developed collaboratively by DCSS, fifteen Clerks of Court, the Attorney General's office, and court administration, generates court-accepted arrears statements. To use eCalc, the court order must have been issued by an Arizona court with payments made through the State Disbursement Unit.
Payment application rules changed on December 1, 1998. For arrearages in non-DCSS cases, payments apply first to principal and then to interest as of that date. Payments made before December 1, 1998 applied first to interest and then to principal. This distinction can significantly affect total amounts owed on long-standing arrearages.
Enforcement Consequences for Non-Payment
Arizona enforces child support orders through multiple mechanisms including license suspension, wage garnishment, tax refund interception, and criminal prosecution. Under A.R.S. § 25-518, the state can suspend driver's licenses, professional licenses, and recreational licenses for parents who fall significantly behind on payments. License reinstatement typically requires full payment or establishment of an approved payment plan.
Contempt of court represents the most severe enforcement remedy available in Arizona family courts. Under A.R.S. § 25-511, judges can impose fines and incarceration for willful non-payment. The court can order work release or work furlough from county jail until the parent pays a specified purge amount. First-time contempt findings may result in up to six months in jail and fines up to $2,500 for misdemeanor violations.
Failure to pay child support can constitute a Class VI felony in Arizona, punishable by up to 1.5 years in prison for severe or repeat violations. State and federal tax refunds can be intercepted to satisfy arrearages, and the Arizona Department of Economic Security maintains a public list of wanted child support evaders for parents owing substantial amounts.
Parents facing enforcement actions should contact DCSS immediately to discuss payment arrangements. Voluntary compliance and good-faith payment efforts typically result in more favorable treatment than forced collection through contempt proceedings.
Modifying Child Support Payment Amounts
Arizona allows child support modification when circumstances change substantially and continuously under A.R.S. § 25-503. A 15% or $50 monthly difference between the current order and a recalculated guideline amount constitutes a substantial change as a matter of law, automatically qualifying for modification review. Filing fees for modification petitions vary by county but typically cost approximately $162 for a Petition for Order to Show Cause.
Parents seeking modification must file a Petition to Modify Child Support with the Superior Court in the county where the original order was issued. The 2022 Arizona Child Support Guidelines remain in effect through 2026, establishing support obligations for combined monthly incomes from $1,000 to $30,000. Courts may impute minimum wage income at $15.15 per hour ($2,626/month) for parents found voluntarily unemployed or underemployed.
Fee waivers and payment plans are available for qualifying low-income filers. The Deferral Application is available at no charge from Law Library Resource Centers throughout Arizona. Parents who cannot afford filing fees should request a deferral when submitting modification paperwork to the Clerk of Superior Court.
