FedNow and the RTP network are the two real-time payment rails operating in the United States. Both clear and settle in seconds, run 24 hours a day every day of the year, and cap individual transfers at $10 million. The core difference is who runs them and how the money actually moves: FedNow is operated by the Federal Reserve and settles directly through each bank’s master account at a Reserve Bank, while RTP is operated by The Clearing House, a private company owned by large commercial banks, and settles through a joint prefunded account.1FedNow Explorer.

Side-by-Side Comparison
The two networks share a goal but differ in structure, mechanics, and governance.
- Operator. FedNow is a public utility run by the Federal Reserve. RTP is a private network operated by The Clearing House, owned by large commercial banks.
- Settlement. FedNow debits and credits participants’ master accounts at a Federal Reserve Bank in real time, with no prefunding required. RTP settles through a joint prefunded account, with designated funding agents supplying liquidity.1FedNow Explorer. FedNow Features – Settlement, Reporting and Liquidity Management
- Transaction limit. Both networks cap individual transfers at $10 million. RTP raised its ceiling from $1 million to $10 million in February 2025. FedNow raised its ceiling from $1 million to $10 million in November 2025. Individual banks can still set lower internal limits for their customers.2Federal Reserve Financial Services.

- Processor flexibility. FedNow lets a single participant use multiple sending processors, all settling to the same master account. RTP limits each participant to a single processor, which can complicate banks running multiple technology vendors.
- Fraud controls. FedNow provides network-level tools such as negative lists and account activity thresholds that apply across all of a bank’s processors. On RTP, banks rely more heavily on their processor for those controls.
Many larger banks connect to both networks to maximize the number of counterparties they can reach. Neither network is a replacement for the other on the receiving side: a payment initiated on RTP can only be received by an RTP participant, and the same applies to FedNow.
What FedNow and RTP Have in Common
Both networks are built on the same underlying model. Clearing and settlement are separated: the clearing layer exchanges messages confirming account details, amount, and any remittance data, and the settlement layer moves the money by debiting the sender’s bank and crediting the receiver’s bank. Validation happens before funds commit, which reduces errors without adding delay.
Both use the ISO 20022 messaging standard, which structures payment data into defined fields for invoice numbers, amounts due, due dates, and other remittance details rather than a single text string.4FedNow Explorer. FedNow Service ISO 20022 Readiness Guide Both operate around the clock, every day.
Both also run on a tight clock at the transaction level. FedNow’s operating procedures set a 20-second window from when a payment message is created to when it must either settle or be rejected, with the receiving bank getting up to five seconds to decide whether to accept.5Federal Reserve Services. FedNow Service Operating Procedures Most payments settle in well under five seconds.
Finality: The Rule That Changes Everything
The defining feature of both networks is finality. Under Article 4A of the Uniform Commercial Code, a funds transfer is complete when the beneficiary’s bank accepts the payment order.6Legal Information Institute. UCC Article 4A – Funds Transfer Once accepted, the sender cannot unilaterally cancel or reverse the payment. Cancellation only works if the receiving bank agrees or the network’s rules specifically permit it. That is a sharp departure from credit cards, where chargebacks can claw back funds months later, and from ACH, where certain returns can be initiated days after settlement.
For consumers, this creates a gap. Authorized push payment scams, in which a fraudster convinces you to send a payment yourself by impersonating a bank, agency, or business, sail through fraud filters because you authorized them, and the money is typically gone within seconds. Consumer protection laws in the United States generally do not cover authorized push payment scams; liability protection applies only when someone else initiated the payment without your permission. In 2023, customers at the three largest banks on Zelle, which uses similar push-payment mechanics, disputed more than $206 million in scam transactions and bore more than 80 percent of those losses.7Federal Reserve Bank of Kansas City.

Finality also does not mean errors cannot be fixed. FedNow provides a formal Request for Return process. A bank that discovers an erroneous payment can send a return request to the receiving bank, and the operating procedures direct that these requests be submitted within 60 calendar days of the original settlement date. The receiving bank is not obligated to honor the request. It can return the funds, decline, and the network cannot force a return. Two exceptions extend beyond that 60-day window: confirmed fraud, which is not subject to the 60-day guideline, and Request for Payment warranty breaches, which allow a return request up to 95 calendar days after settlement, with the sending bank given 20 business days to respond.8Federal Reserve Services. FedNow Service Operating Procedures
Under Regulation J, a sender that believes a FedNow payment was unauthorized or executed in error has 60 calendar days after receiving notice of the debit to notify its Federal Reserve Bank. That deadline applies to the bank-to-bank relationship, not to a consumer’s rights against their own bank.9eCFR. 12 CFR Part 210 Subpart C – Funds Transfers Through the FedNow Service
The practical takeaway for anyone sending money on either network: treat it like handing over cash. Recovering it depends on the other party’s willingness to send it back.
Who Can Join Each Network
Both networks limit direct participation to regulated depository institutions. RTP is open to any insured depository institution regardless of size, and to uninsured branches or agencies of foreign banks.10The Clearing House. Real Time Payments Network For FedNow, a participating institution or its correspondent must maintain a master account at a Federal Reserve Bank, and the legal framework sits in Regulation J, Subpart C of 12 CFR Part 210.9eCFR. 12 CFR Part 210 Subpart C – Funds Transfers Through the FedNow Service
FedNow offers three participation types, which lowers the barrier for smaller institutions:
- Receive only, meaning the institution can receive customer payments and send Requests for Payment, but cannot initiate credit transfers.
- Send and receive, which is full participation for customer credit transfers, returns, and optionally incoming Requests for Payment.
- Liquidity management transfers only, which connects the institution solely to move funds between master accounts.11Federal Reserve Financial Services. FedNow Service Participation Types
How Fintechs Reach These Networks
Fintechs and other non-depository companies cannot directly join FedNow or RTP. They reach real-time payments through two paths: acting as a service provider for a participating bank, or using a sponsor bank that processes transactions on their behalf.
On FedNow, a service provider is an agent authorized by a participant to initiate and receive messages, operate the electronic connection, select security settings, and access transaction information. Every rule that applies to the bank also applies to the service provider when it performs those functions, including the certification requirements before going live.
The sponsor bank model carries different trade-offs. The fintech depends on the sponsor bank for connectivity, settlement, and technical support. That sponsor bank is often a competitor in the same market, which can create tension around data sharing and pricing. Fees for indirect access vary widely, and the sponsor bank can end the relationship at its discretion.
Choosing Between Them
For a bank, the deciding factors are usually reach, settlement preference, and existing technology. Connecting to both networks reaches the widest set of counterparties. Institutions that prefer to avoid prefunding a joint account favor FedNow’s direct master-account settlement. Institutions running multiple processors also benefit from FedNow’s flexibility, since RTP requires a single processor per participant.
For a business or consumer, the choice is usually made by your bank, not by you. What you see is a real-time payment option in your banking app or portal; what runs behind it is whichever network your bank participates in. The rules that matter to you, chiefly finality and the limited path to reversing an erroneous payment, are the same either way.
