The Single Euro Payments Area (SEPA) is a payment-integration system of the European Union that makes cross-border bank transfers in euros as fast, cheap, and simple as domestic payments. It allows individuals and businesses to make cashless euro transfers to any account within the zone using a single bank account and an International Bank Account Number, under the same basic conditions and charges as transfers within their own country.

Standard SEPA credit transfers settle within one business day, while the instant scheme (SCT Inst) processes payments in less than ten seconds around the clock. As of 2025^([update]), SEPA covers 41 countries: the 27 member states of the European Union, the four EFTA states (Iceland, Liechtenstein, Norway, and Switzerland), the United Kingdom, four European microstates (Andorra, Monaco, San Marino, and Vatican City), and five EU candidate countries (Albania, Moldova, Montenegro, North Macedonia, and Serbia).

SEPA covers predominantly standard bank transfers. Payment methods that include additional proprietary features, such as specific mobile payments or smart card payment systems, are not directly covered. However, the instant SEPA payment scheme facilitates digital retail payment services directly from smart devices.

The aim of SEPA as stated in 2008 was to improve the efficiency of cross-border payments and turn the previously fragmented national markets for euro payments into a single domestic one. SEPA enables customers to make cashless euro payments to any account located anywhere in the area, using a single bank account and a single set of payment instruments. People who have a bank account in a eurozone country can use it to receive salaries and make payments throughout the zone, for example when taking a job in another member state.

The project includes the development of common financial instruments, standards, procedures, and infrastructure to enable economies of scale. As of 2007^([update]), it was estimated this could reduce the overall cost to the European economy of moving capital around the region by up to 2–3% of total GDP.^([needs update])

SEPA does not cover payments in currencies other than the euro. This means that domestic payments in SEPA countries not using the euro continue to use local systems, while cross-border transactions involving the eurozone rely predominantly on SEPA in euros.

The different functionalities provided by SEPA are divided into separate payment schemes.

SEPA Credit Transfer (SCT) allows for the transfer of funds from one bank account to another. SEPA clearing rules require that payments made before the cutoff point on a working day be credited to the recipient's account by the next working day. The scheme was introduced in January 2008. In February 2014 it replaced the national credit transfer schemes, and later made the use of International Bank Account Number mandatory for transfers.

SEPA Instant Credit Transfer (SCT Inst), also called SEPA Instant Payment, provides for instant crediting of a payee, the delay being less than ten seconds, initially, with a maximum of twenty seconds in exceptional circumstances. This scheme was launched in November 2017, and was at that time operational for end customers in eight Eurozone countries.

As of 2024, not all banks offer their customers instant transfers; however, in March 2024 the EU adopted the Instant Payments Regulation which requires all banks to offer instant transfers from January 2025 (incoming transfers) / October 2025 (outgoing transfers).
