Hi emmybl,
This is a great chance to take. It never hurts to ask questions before diving in with a software, and, as it turns out, this is the perfect question to ask for QuickBooks Self-Employed. I'd be happy to go over this with you so you can decide which version of QuickBooks is best for you.
QuickBooks Self-Employed is a streamlined version of the software that gives you the chance to record invoices, expenses, mileage, and sales tax. The program's sales tax processing is actually the reason why you've asked a perfect question. If sales tax is a feature you need, it's available in the program, however, QuickBooks Self-Employed does not currently support Quebec sales tax. You can learn more here: Sales Tax overview
In light of that, QuickBooks Online may be a better fit for you, depending on your needs. QuickBooks Online supports all provincial and territorial sales tax, but this version of the software is designed for small businesses rather than self-employed entrepreneurs. This means you wouldn't be able to record your personal transactions in the program like you can with QuickBooks Self-Employed. To see if QuickBooks Online is a good fit for you, you can learn more about it here: QuickBooks Learn & Support
In the event you've already got a QuickBooks Self-Employed account and would like to make the switch to QuickBooks Online, this article can help: Switch from QuickBooks Self-Employed to QuickBooks Online
I hope this helps! Feel free to post a reply here if you've more questions. :)
