Troubleshooting

We recommend that you wait until the Netfile and Refile services open by CRA on Monday, February 23, 2026, at 6:00 a.m. (Eastern time). If you need to make changes before February 23, 2026, you must wait until the service is reopened or submit a paper T1-ADJ form.  Currently, there is no other way to electronically transmit your return to CRA. 

You are receiving this error because Netfile and re-filing are currently closed for all the tax years.
