Hello, I'm trying to send my taxes via ImpôtNet Québec but I'm always getting an error telling me that I have to fill out the TP-64.3 however, I have completed the form but still the system doesn't allow me to send it. Am I missing anything? The only thing I can see is that I don't have handy the identification number of my employer (to note I'm working for the federal government), could it be the problem?
Thanks for your help,
