Introduction of a new universal payment slip (TUP) from 2 June 2025

Still 1.2 million TUP transfer orders every year

Despite the rise of digital banking, Luxembourg still sees around 1.2 million TUP-based transfer orders annually. Whether it is companies receiving invoice payments, associations collecting donations, or individuals transferring funds to friends and family, these transactions require reliable and secure banking infrastructure.

While the vast majority of transfers now occur through cards, direct debits or digital credit transfers, many people still rely on the TUP for its simplicity. Pre-filled data and a familiar format make it a preferred option, particularly for those less comfortable with online banking.

A more efficient process with better-structured data

To improve the processing of TUP-based payments, ABBL member banks and payment service providers (PSPs), together with Victor Buck Services, have modernised the TUP slip. The updated format features better-structured data, enabling more secure and efficient processing.

Starting 9 October 2025, users will also have the option to indicate whether their transaction should be treated as an instant payment, depending on their bank’s capabilities.
