How to set up tax?

Welcome to the Community.

Did you encounter issues or an error message when setting up tax in QuickBooks Online (QBO)? If so, can you provide us with more detail about your concern? It is for us to give you an accurate solution.

Moreover, QBO can occasionally stop working properly since locally stored internet cache files can cause the product to behave unexpectedly due to overloaded site data. I recommend opening a different browser or a private window to isolate possible issues. This can help us remove any cache-related matters that may have contributed to the problems.

Here's how to activate incognito mode in some of the most common online browsers:
 

• Google Chrome: Ctrl + Shift +N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Option + P

If you're finally able to set up Sales Tax, it's safe to say that the browser has caused it. This can be fixed by clearing your cache and cookies.

Additionally, I'll also share this link where you can search for articles to guide you in managing your taxes in QuickBooks: Help Articles for Taxes in QuickBooks Online.
