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:
