Florida requires all child support payments to be processed through the Florida State Disbursement Unit (SDU), not paid directly between parents. Under Fla. Stat. § 61.1824, the SDU collects and disburses all court-ordered support payments, with a depository fee of 4% (minimum $1.00, maximum $5.25) applied to each payment. Parents can pay online at fl.smartchildsupport.com with a 2.5% debit card fee, through Walmart for $2, by mail to P.O. Box 8500 in Tallahassee, or via automatic wage withholding that can garnish up to 65% of disposable income for parents more than 12 weeks behind on payments.

Understanding the Florida State Disbursement Unit
The Florida State Disbursement Unit processes over 1.5 million child support payments annually and serves as the mandatory clearinghouse for all court-ordered support in the state. Established under Fla. Stat. § 61.1824 and federal welfare reform requirements, the SDU provides a single address for employers, parents, and agencies to send all support payments. Direct payments between parents are not legally recognized and do not satisfy court-ordered obligations, meaning a paying parent who hands cash directly to the other parent still owes the full amount through official channels.
The SDU operates in coordination with the Florida Department of Revenue Child Support Program, which enforces support orders and tracks compliance across all 67 Florida counties. Every payment processed through the SDU creates an official government record that protects both parents in future enforcement or modification proceedings. Parents can access their payment history 24 hours a day through the online portal or by calling 1-877-769-0251.
Federal law requires the SDU to disburse payments within 2 business days of receipt when the payee has signed up for electronic disbursement. Parents receiving support can enroll in direct deposit by submitting a paper application with a voided check or bank letter, with activation taking up to 5 business days. Alternatively, the SDU issues payments through the Way2Go prepaid debit card administered by Comerica Bank, which can be used anywhere Mastercard is accepted.
Online Payment Options Through fl.smartchildsupport.com
The Florida Smart Child Support portal at fl.smartchildsupport.com accepts debit cards, credit cards, and electronic checks for child support payments with varying fees and processing times. Debit card payments incur a 2.5% convenience fee and process within 2 business days. Credit card payments carry a 3.5% fee with 2-3 business day processing. Electronic check payments process with no fee in 4 business days. Payments made after 8:45 PM Eastern Time are credited to the next business day.
To make an online payment, parents need either their 10-digit child support case number or the 9-digit numeric portion of their court case number plus their Social Security number. First-time users must create an account at fl.smartchildsupport.com before scheduling payments. The portal allows one-time payments or recurring automatic payments aligned with pay schedules.
The Pay by Text feature enables parents to receive text message reminders when payments are due and authorize payments by replying with a confirmation code. This text-to-pay option uses the debit or credit card on file and applies the same 2.5% or 3.5% convenience fees. Parents must opt in through their online account to activate text payment notifications.
Phone payments are also available by calling the SDU Payment Center at 1-877-769-0251 and selecting option 5. A customer service representative processes credit card payments (Mastercard, Visa, Discover, American Express) with the standard 3.5% fee. Phone payment processing takes 2-3 business days.
Wage Withholding and Income Deduction Orders
Florida law has required automatic income withholding for all child support orders since 1988, making wage garnishment the most common payment method in the state. Under Fla. Stat. § 61.12, employers must begin withholding within 15 business days of receiving an Income Deduction Order (IDO) and remit payments directly to the State Disbursement Unit. The paying parent remains responsible for any support payments due before income deduction begins.
Federal law caps child support wage garnishment at 50% of disposable income for parents supporting another spouse or child, or 60% for parents without other dependents. Florida adds an additional 5% garnishment for parents more than 12 weeks (approximately 3 months) behind on payments, bringing the maximum withholding to 65% of disposable income. Disposable income means gross pay minus mandatory tax withholdings.
Employers face legal liability if they fail to comply with income deduction orders. Under Florida law, employers cannot fire, discipline, or retaliate against employees because of child support wage garnishment. The employer must send withheld amounts to the SDU within 7 business days of each pay period. Employers required to remit taxes electronically must also remit child support payments electronically under Fla. Stat. § 61.1824.
Parents who prefer wage withholding can request an income deduction order even when not required by the court. This approach ensures consistent, automatic payments and creates a clear record of compliance. The SDU coordinates with employers across all 50 states, so wage withholding continues even if the paying parent relocates.
Cash Payments at Walmart
Parents who need to pay child support in cash can use any Walmart MoneyCenter location in Florida for a flat $2 fee regardless of payment amount. The paying parent provides their depository number and uses biller name "Florida SDU" to complete the transaction. Walmart processes cash payments within 1-2 business days, making this one of the fastest payment methods available.
The Walmart payment option accommodates parents without bank accounts or those who prefer handling transactions in person. Walmart MoneyCenter hours vary by location but typically operate from 8 AM to 8 PM seven days a week. Parents should retain receipts as proof of payment until the transaction appears in their SDU payment history.
Effective January 1, 2026, Manatee County Clerk of Court no longer accepts child support payments at its office, directing parents to Walmart, online payment, or mail options instead. Other Florida counties may follow similar policies, making third-party payment locations increasingly important for in-person transactions.
Mail Payments to the State Disbursement Unit
Parents can mail child support payments by check or money order to: Florida State Disbursement Unit, P.O. Box 8500, Tallahassee, Florida 32314-8500. All payments must be made payable to "FLSDU" and include the payer's name, the other parent's name, and the child support case number or depository number. The standard 4% depository fee applies to mailed payments.
Mailed payments have the longest processing time, typically taking 5-7 business days from mailing to credit. Parents should mail payments at least 10 days before the due date to ensure timely processing. Certified mail with return receipt provides proof of mailing date if payment timing becomes disputed.
The SDU does not accept cash through the mail. Personal checks, cashier's checks, and money orders are acceptable. Payments missing required identifying information may be delayed or returned. The SDU processes mail payments in the order received and cannot expedite individual transactions.
Receiving Child Support Payments
Parents receiving child support have two electronic disbursement options: direct deposit to a personal bank account or the Way2Go prepaid debit card. Under Fla. Stat. § 61.1824, all payments must be disbursed electronically. Parents who do not designate a personal account automatically receive payments through the stored value Way2Go card.
Direct deposit enrollment requires submitting a paper application to the SDU with a voided check or bank letter showing routing and account numbers. Processing takes up to 5 business days after the SDU receives complete documentation. Direct deposit eliminates waiting for cards or checks and typically provides fastest access to funds.
The Way2Go card functions as a Mastercard debit card usable at any merchant accepting Mastercard, including ATMs, grocery stores, online retailers, and bill pay services. Cardholders can check balances at goprogram.com, through the Way2Go mobile app, or by calling cardholder services. The card includes fraud protection and can be replaced if lost or stolen. Initial card issuance is free, though replacement cards may incur fees.
Depository Fees and Transaction Costs
Under Fla. Stat. § 61.181(b)(1), the Florida SDU charges a 4% depository fee on all payments with a minimum of $1.00 and maximum of $5.25 per transaction. This fee applies regardless of payment method, including mailed checks, online payments, and Walmart transactions. The depository fee is separate from payment method convenience fees.
Total payment costs vary by method. A $500 payment by debit card costs $12.50 in convenience fees (2.5%) plus $5.25 depository fee, totaling $17.75 in fees. The same payment by electronic check costs only the $5.25 depository fee with no convenience charge. Cash at Walmart costs $2.00 plus the $5.25 depository fee for $7.25 total.
Cases involving the Florida Department of Revenue Title IV-D enforcement do not pay the Clerk depository fee, reducing costs for parents in DOR-enforced cases. Parents can verify whether their case is Title IV-D by checking their case documentation or calling the child support program at 1-850-488-5437.
Consequences of Nonpayment
Florida aggressively enforces child support obligations through wage garnishment, license suspension, contempt proceedings, and criminal charges. Parents who fall behind on support face accumulating interest at rates between 5.81% and 12% annually on unpaid amounts. The Department of Revenue can intercept federal tax refunds, lottery winnings, and unemployment benefits to satisfy arrears.
Under Fla. Stat. § 827.06, parents four months late who owe at least $2,500 face first-degree misdemeanor charges punishable by up to one year in jail and $1,000 in fines. Parents one year or more behind who owe $5,000 or more face third-degree felony charges carrying up to five years in prison, $5,000 in fines, and five years probation.
The Florida Department of Motor Vehicles can suspend driver's licenses and vehicle registrations for delinquent child support. Professional, occupational, and recreational licenses (including hunting and fishing) are also subject to suspension. License reinstatement requires paying arrears in full or entering an approved payment plan.
Civil contempt proceedings allow courts to jail non-paying parents until they pay, with sentences typically ranging from a few days to six months depending on the county and circumstances. However, under the landmark ruling in Bowen v. Bowen, 471 So. 2d 1274 (Fla. 1985), courts cannot incarcerate parents for civil contempt unless they have the present ability to pay the ordered amount. This protects genuinely indigent parents from imprisonment solely for inability to pay.
2026 Law Changes Under House Bill 1014
Effective January 1, 2026, House Bill 1014 significantly updated Florida's child support calculation and modification rules. The combined parental net income limit increased from $12,000 to $50,000 per month, affecting high-income support calculations. The self-support reserve now equals 180% of federal poverty guidelines, protecting lower-income paying parents from orders that leave them below subsistence levels.
Modification thresholds require a 15% or $50 difference between current and guideline amounts before courts recognize a substantial change in circumstances. Title IV-D cases enforced by the Department of Revenue use a lower 10% or $25 threshold. These thresholds prevent minor income fluctuations from triggering modification litigation.
Parents with at least 20% of overnight parenting time (73 or more nights annually) may see adjusted support obligations under the 2026 guidelines. The Income Shares Model continues to calculate support based on combined parental net income and number of children, but time-sharing now factors more prominently into the calculation.
Modifications take effect only from the filing date, not retroactively. Parents seeking modification must file a petition with the court demonstrating the substantial change and providing current financial documentation. Simply agreeing privately to modify payments does not change the legal obligation under the existing court order.
Why Direct Payments Between Parents Are Not Allowed
Florida law prohibits direct child support payments between parents because such arrangements cannot be properly tracked, verified, or enforced. The Florida Fourth District Court of Appeal in Golson v. Golson, 207 So. 3d 321 (Fla. 4th DCA 2016), confirmed that parents cannot contract away a child's right to properly routed support payments. Informal arrangements leave both parents legally vulnerable.
A paying parent who hands cash directly to the other parent still owes the full amount through official channels because the direct payment does not discharge the legal obligation under the court order. Even if both parents agree to the arrangement, the receiving parent cannot waive the child's right to support paid through proper mechanisms. The paying parent may later face enforcement actions for the full "unpaid" amount.
If parents wish to change payment arrangements, they must petition the court for a modification. The court reviews any proposed changes to confirm guideline compliance or properly documented deviation. Informal agreements, handshake deals, and text message confirmations have no legal effect on the underlying support order.

The paying parent should file a motion to terminate once the child reaches emancipation age and confirm the obligation has ended through the court.
