CRA Notice of Assessment Calculation Error

Vipul Thakkar · ‎May 08, 2025

I have few clients who received NOA for 2024 tax and received significantly less refund or more amount to pay that what we calculated suing Profile.

There are no details avilable in NOA except "Because of a calculation error, we changed your federal tax payable to $....... As a result, your total payable has changed."

Double checked all the entries in tax return but everything seems perfect. Profile Helpdesk also confirmed this and said they do not see any error in software.

Tried calling CRA since past several days [atleast 50 times] but no luck so far, hence thought of find out from Community if any one knows the reason for this.

Yes, some of my clients got the same calculation error for the ACWB on their 2024 NOA. I would also like to know whether this is a Profile tax software error or CRA calculation error, so I can advice my clients accordingly.

One of my clients also received this message on the Notice of Assessment. Nothing appears amiss in Profile.

We are going to have to call CRA.

Did you ever find out from the CRA about the "calculation error"? I have a client with the same problem and not sure how to proceed. CRA impossible to reach right now.
