Hi gsb06. Knowing the right tax code to use is essential when it comes to recording your transactions. Here's an article which shows you the types of tax codes included in QuickBooks: Common sales tax codes. I'd also recommend reaching out to your accountant for expert advice on which tax code works best for your scenario. If you're not in contact with one, I encourage you to search for one on our website using this link here. I'll leave this question here so other accounting professional members can chime in. Let me know if you have other questions. I'm here to help.
