How do i check to see that my Revenue Quebec taxes are being sent out today?

Did you sent your file electronically to Revenu Québec?  If yes, and you have received a confirmation number, Revenu Québec has received it.  If you have an amount due, you will have to pay separately through your financial institution.

You can confirm the status of your Québec return and find out when the RQ is going to issue your tax refund using Revenu Québec's Refund Info-Line service: https://www.revenuquebec.ca/en/online-services/online-services/refund-info-line/
