Australian Taxation Office payments – Payment Reference Number (PRN) validation companion guide

This guide provides information to assist in validating Payment Reference Numbers (PRN) for Australian Taxation Office payments.

We receive over 32 million payments annually. Of these, approximately 10% of payments require correction due to mistakes made by the client when sending the payment to us. Using the correct PRN will ensure there is no delay in payments being credited to the correct account or unnecessary debt collection activity occurring. 

This guide contains instructions and samples, to assist digital service providers and other parties to appropriately validate an ATO PRN.
