Error - Quebec identification number QST/ PST number - invalid format

If you receive the message, "You entered an invalid number or an invalid format for the Quebec identification number (QST) or the PST number", please go to the first page of your business statement ("Business ID") on the "Interview" tab, and correct the "Quebec identification number" and/or "PST registration number of your business" (if present). They are both supposed to be in the format 1234567890TQ1234 (e.g. 1234567890TQ0001).

I also send you a link from Revenu Québec, which will allow you to verify the validity of your QST /PST numbers:
