Why do we need proof of your PPSN/Tax Reference Number?

From 29th June 2009, financial institutions are obliged to request customers to provide their tax reference number (e.g. Personal Public Service Number (PPSN) or Corporation Tax number) when they open a new current or deposit account which may give rise to the payment of such interest by their financial institution. Under the Regulations, this number will be included in the annual return of interest to the Revenue Commissioners. Financial institutions are also obliged to request personal customers to provide suitable documentation to verify their PPSN (in the form of a P60, Notice of Tax Credits, Payslip, Tax Assessment etc). It should be noted that the PPSN will only be used for the purpose of making this annual return to the Revenue Commissioners.

If customers fail, for whatever reason, to provide their tax reference number and/or the PPSN supporting documentation, financial institutions are required to indicate this on the annual return of interest.

These regulations and guidance notes are available on the Revenue website at

The following documentation (original or copy) may be used to verify the tax reference number as required under the current regulations.
