Hi there jten_bribke-hotm,
Thanks for reaching out about your taxes. QuickBooks Online is a great tool able to help you keep track of tax on transactions so you know the amount owed to the government. I can point you in the right direction for assistance with tax for companies without an HST number.
To know if you should be keeping track of these transactions since you don't have an HST number, as well as how it should be tracked since it might not be owed to the government, I recommend speaking to your accountant. They'll be able to best assist in making sure those taxes are entered correctly if they do indeed need to be entered so that your books can be well balanced. You can invite your accountant to your QuickBooks Online account by clicking on the My Accountant tab. There's also an option to find an accountant near you in that section by clicking on the Find a Pro to help button.
If you have any other questions, feel free to reach out here.
