If you need to complete an income tax return to send it to Revenu Québec, you'll need to create a new profile to submit solely a provincial return. You can create a new profile using the dropdown menu in the top left navigation bar of your Wealthsimple Tax account. Visual instructions can be found in this help centre article.
You'll need to answer "Québec" to the question "In which province or territory did you live on December 31?".
Once you've completed your return and you are ready to file, click the Review & optimize button in the Review & optimize section, and clear any errors (in red/pink) that appear. If you still don't see the Submit section, click the Review & optimize button one more time.
When your return is free from all errors, the Submit section will appear. Click Submit Tax Return and follow the on-screen directions to submit it to Revenu Québec.
