Error 35

[JessicaMorrow]

I am getting an Error 35 when trying to file my mother's taxes for 2025. She passed away in 2026 so I understood everything should be 'normal for 2025' but is this the reason I am getting the error? Also, when I print the tax forms to mail in, it is asking for a signature from her and my dad to approve the pension splitting. How do I go about that if I have to paper file?

The CRA's "Error 35" (often specifically Result Code 35) is the software's way of saying, "This return cannot be sent electronically."

Even though your mother was alive for all of 2025, once the CRA is notified of a death (which likely happened when the 2026 death certificate was issued or CPP was notified), her Social Insurance Number (SIN) is "flagged" in their system.

You cannot use NETFILE (electronic filing) for a deceased person's return.

The CRA requires a physical signature from the legal representative (executor) to authorize the filing, and their automated system for individuals isn't set up to verify that authority electronically for a deceased SIN.

As the executor or legal representative, you (or whoever is the legal executor) must sign the return on her behalf.

You should sign as "[Your Name], Executor for the Estate of [Mother's Name].

Important: Ensure the CRA has a copy of the will or the Form RC4649 (Legal Representative Agreement) on file. If they don't, they won't process the return you sign.

Thank you for choosing TurboTax.

Thank you! very helpful. One last question. The form required a signature form the transferring spouse and the receiving spouse. My dad is the executor - I was just the representative for CRA. Does my dad just sign the form twice?

Because your father is the executor, he has the legal authority to sign on behalf of your mother's estate. In this case, yes—he will sign the forms.
