Hi dan-iddigital-or,
Welcome to the Community. It's important to correctly record your sales tax to ensure that the correct informtion is submitted to Revenue Quebec. QuickBooks Online is a flexible program that simplifies the way you manage your books. I'd be glad to provide you with information on sales tax exceptions.
In QuickBooks Online, sales tax exceptions are transactions that you have previously filed for, but have since changed, deleted, or added. I encourage you to consult an accountant to review your exceptions to keep your books balanced. If you don't have an accountant, we can help you locate a ProAdvisor in your local area.
Let me know if you have any questions, I'll be happy to help.
