I think I will take a look at the other package mentioned above that looks like the actual forms.
I have used StudioTax a few times now and like it. It costs $15 for 20 returns, but free if you are below 20k income.
https://www.studiotax.com/home.htmlI have played with TaxFreeway and it also seems serviceable, but maybe a bit less smooth:
https://www.taxfreeway.ca/For tax software in the cloud, I would only use it if the system was "zero-knowledge", meaning the company cannot read your information since it is encrypted on your own machine before it is stored in the cloud. This is the model that SimpleTax used to have before they were bought. It is also the model that good-quality password managers use, and some backup services like SpiderOak.
These days, I would much rather pay money so that I am the customer, not the product.
