Hello there, @accounts430.
Thank you for asking us here in the Community. At the moment, adding multiple GST numbers is unavailable.
As a workaround, you can open a separate QuickBooks account for each tax id.
I appreciate your idea of this feature. We're continuously making improvements to our product, and this preference might be available in the future.
As we assess this, I suggest you visit our QuickBooks Resource Center to stay updated with all the changes.
I also recommend reading through this article to learn how to handle GST in QuickBooks: Setting up QuickBooks for GST.
Feel free to posts again at any time, @accounts430. I'd be here to help. Take care!
