Thanks for your post.

I followed your instructions to find out my client’s (JOHN SMITH) confirmation notice using his SIN (XXXXXXXXX).

• There were 3 files with the client’s SIN.
• I opened the “XXXXXXXXX_response.xml” file.
• Then in the middle was the following message:

“<t1rsp:MessageText xml:lang="en">The 2020 tax return for JOHN SMITH has been successfully received and has been processed by the Canada Revenue Agency. The same selection criteria for verifying income tax returns are used for both paper and electronic versions. Your client needs to keep all tax information slips and documents for six years after you filed the tax return. Please keep this confirmation number and DCN for your records: [the DCN number follows]</t1rsp:MessageText>”
