The manage sales tax button does not work, it disappears when clicked upon. I am trying to setup the GST sales tax.

Hello mike376,

Your taxes play a vital role in keeping your books accurate. It's essential you're able to reap the amazing benefits of the tax module offered in QuickBooks without running into issue. Don't worry, I've got your back. I'll be happy to give you a hand with this going forward. 

First, I'd like to start off by troubleshooting this issue to determine if it's a browser-related issue. Clearing cache and cookies is a great way to clean your browser allowing it to work more efficiently. Here's an article that shows you how to do that: How to clear cache and cookies. If this doesn't work, I suggest using a private/incognito window to see if that works instead. Try this out and let me know what happens.

I'll be one message away in case you need further assistance. 

None of this works at all.
