Like any payment method, SEPA Direct Debit may experience unsuccessful transactions. These are called R-transactions. There are
4 types of R-transactions that can happen at various stage of the SEPA Direct Debit timeline.


  • Reject: The debtor bank rejects the SEPA Direct Debit (SDD). This may happen if the bank account is closed, invalid or does not exist.
  • Refusal: There can be a refusal for a single transaction (the mandate remains valid for further transactions) or a revocation of the mandate, meaning additional transactions will be systematically refused.
  • Return: The debtor bank returns the SDD because there was an issue while processing the SDD. The vast majority of returns are because of insufficient funds on the debtor account.
  • Refund: Between D and D+8 weeks, the debtor can ask for a refund without any justification. Between D+8 weeks and D+13 months, the debtor can only initiate a refund in the case where they claims to never have signed a mandate.


The R-transactions can have various root causes. Here is an overview of the most common type of R-transactions:

AM04; MS03   Reject or Return       Insufficient funds (it is the most commun in Europe)
