I remember working at the book keeping firm and she used to make some adjustments before filing. When I click on File Sales Tax, the amount on line 109 shows -$23.99 and at the bottom it says "Your HST is ready to file" with green tick mark.
Yes that is the function step to file the sales tax return in QB.
No one external can tell you if you need to make any adjustments - you have to determine that yourself. If every transaction impacting sales tax has been recorded using the 'sales tax code' on a QB document then likely there are no 'adjustments' required. But if anything has been posted by journal entry, or if you have made any of the 'special' transactions that have to reported separately on the tax return then an "adjustment" will be needed to make those entries onto the tax form.
Note that if you select the "online filing" option then QB will create a special file that you upload to CRA. The upload is a separate step you have to execute after the report creation is finished. If you file manually, or by GSTnetfile, or using a banks "tax filing" portal, then you should select "paper or other method" as the QB filing option.
My QB Pro 2020 takes me to CRA's NETFILE page where there is no option to upload the QB .tax file. The HST data then has to be entered manually. How can QB be set up to go to CRA's Internet File Transfer page where the .tax file can be uploaded directly?
I found this way works but I was expecting it to be all automatic.
you have to find on cra "internet file transfer" from there you can attach your file you will need your cra web access code. then pay from "my payment"
