I can tag AR invoices, but tagging expenses is missing. Where is the tag field for expenses and bills?

Allow me to help you resolve this tags issue so you can categorize your expenses and bills, @Sc0.

In QuickBooks, tags are used to label invoices, expenses, and bills. If you're unable to use it on a bill or an expense, let's try some browser troubleshooting to resolve it.

For now, login to your account in a private web browser. Unexpected issues in QuickBooks are sometimes associated with the amount of data stored in the cache.

A regular browser will constantly overwrite itself and will not remove history unless done manually. Private browsing will not save any history, so it's a great place to identify issues in the browser. Use these keyboard shortcuts to launch a new private window:

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

You may try a different browsers too, and see if the problem persists there. If you can use the tags feature in QuickBooks without any issues using the workarounds, clear the cache to start with a clean slate.
