ExpertPay is an online platform that lets a non-custodial parent (or an employer withholding from a paycheck) send child support electronically to any state, Puerto Rico, or Washington, D.C., through one account.1Conduent. ExpertPay Multistate Payment Solution for Child Support It sits between you and your state’s State Disbursement Unit, which is the agency federal law requires each state to run for collecting and distributing support.2Office of the Law Revision Counsel. 42 USC 654b – Collection and Disbursement of Support Payments You register once, link a way to pay, and ExpertPay routes each payment to the right state agency. No checks, no office visits.
What You Need to Sign Up
Registration takes three things: your Social Security Number, a working email address, and the child support case number your state assigned to your order. The case number is printed on your original court order and on any income-withholding notice from a child support agency. If you cannot locate it, call the agency handling your case and ask for the record.
You will also link a funding source by entering your bank’s nine-digit routing number and your account number. ExpertPay verifies the account by sending one or two small test deposits, usually under a dollar, which land in your bank within one to two business days. Log back in, confirm the exact amounts, and the account activates. Most states add a one-time $2.50 registration fee to your first payment.3Office of Child Support Enforcement.

Ways to Pay and What They Cost
ExpertPay accepts bank accounts, Visa, Mastercard, and Discover cards, PayPal, Venmo, Apple Pay, and Google Pay.1Conduent. ExpertPay Multistate Payment Solution for Child Support You can also pay by phone through an automated line at 1-866-645-6347.4ExpertPay. The Child Support Payment Center Fees vary by method and by state:
- Bank account (ACH direct debit): no transaction fee in most states. A few states charge around $1.50 per payment.
- Credit or debit card: a convenience fee of roughly 2% to 3% per transaction. On a $500 payment, that is about $10 to $15.
- PayPal and Venmo: usually the same 2% to 3% as cards, with some states capping the fee at $60 per transaction.
- Apple Pay and Google Pay: vary by state, but generally track the card rates.
These fees are separate from the support you owe. They do not reduce your balance or count toward it. The exact fee shows on screen before you confirm, so you can see the full charge before the money leaves your account. On a $1,000 monthly obligation, the gap between free ACH and a 3% card fee runs about $360 a year. You can store more than one payment method in your profile and switch between them.
How Long Payments Take to Post
Card payments actually move faster than bank transfers here, which catches some people off guard:
- Credit or debit card, PayPal, and Venmo: payments submitted before 5:00 PM Eastern typically process the next business day.
- Bank account (ACH direct debit): up to four business days to clear, because the system verifies funds before pulling them.
Once ExpertPay processes the payment, the money goes to the State Disbursement Unit, which federal law requires to distribute payments within two business days of receipt when the identifying information is sufficient.2Office of the Law Revision Counsel. 42 USC 654b – Collection and Disbursement of Support Payments Realistically, a card payment can be credited in as few as three business days total; a bank transfer might take five or six. Schedule at least a week before the due date. That buffer covers weekends and bank holidays that would otherwise land in the middle of the processing window.
Recurring Payments and Receipts
The member dashboard lets you make a one-time payment or set up a recurring schedule that matches your court order. Recurring debits are the surest way to avoid a missed due date, and missed due dates cost far more than any convenience fee.
Every payment produces a confirmation screen and an emailed receipt. Save them. If a dispute ever comes up about whether a payment went through on time, that digital record is the evidence you bring to court. The payment history tab shows every past transaction and its current status, so you can confirm the state actually received the money, not just that you sent it.
When a Payment Fails
A returned payment is the fastest way to create a problem. If your bank rejects the transaction for insufficient funds, a closed account, or a frozen account, ExpertPay may suspend your account and charge a $20 reversal fee for each failed payment. Repeated failures can lead to the account being closed, and reactivating it may require contacting ExpertPay and paying additional fees.
The larger risk is that the state records a missed payment. A bounced payment gets no credit toward your obligation, even if the money briefly left your account. Contact your State Disbursement Unit immediately to arrange a replacement. Waiting for the system to work itself out is how unexpected arrears build up.
If You Are an Employer
Employers and payroll processors use the same platform to comply with income-withholding orders, which federal law requires them to honor.5Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement Employer registration uses the company’s nine-digit FEIN plus business name and address; from there, employers organize employees into Payment Groups and can bulk-upload withholdings in CSV or fixed-length files. ACH from an employer bank account generally carries no per-transaction fee, so the platform costs businesses considerably less than it costs an individual paying by card.
If You Cannot Afford the Payment
If your finances have genuinely changed, do not stop paying and let arrears accumulate. Contact your local child support agency or file a petition with the court to modify the order. Courts can adjust the amount when there is a substantial change in circumstances, such as job loss or a serious medical condition. Until a judge signs a new order, the original amount keeps accruing, so acting quickly limits what you owe in the gap. Enforcement tools available to states are broad, and include automatic income withholding, seizure of federal and state tax refunds, suspension of driver’s, professional, and recreational licenses, passport denial once arrears pass $2,500, property liens, and credit bureau reporting.5Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement A modified order is far cheaper than any of them.
