Document check using the secure verification code CSV

All documents and certificates issued by the Tax Agency, regardless of how they were requested, have a verification code to allow the recipient to verify their authenticity and validity on the website.Therefore, the Secure Verification Code allows for the integrity of the copy of this electronic document to be verified.

This code can be found at the bottom of the document (e.g. on certificates), or at the beginning (as is the case with tax return submission receipts).

Enter the Secure Verification Code, all in capitals, and click 'Send' to get the PDF containing the document.If you have any problems in seeing the document, click on 'See full screen'. Bear in mind that you need to have a PDF document viewer installed on your computer.Make sure you enter this 16-character code correctly, as otherwise an error message will appear telling you that it has not been possible to retrieve any documents catalogued with this CSV.You can find out where to find the Secure Verification Code by going to the 'HELP Link'.

You can also obtain proof of submission of the return sent by consulting "View tax returns filed".
