I'm here to provide some information regarding your sales tax in QuickBooks Online (QBO), @jantco.
For manual setup, you can create a new custom sales tax rate and then assign the newly created one after inactivating the old one.
If you're using Automated sale tax, since you've already verified the set up I recommend contacting our support team to assist you further.
Here's How:
- Sign in to your QuickBooks Online company.
- Select Help (?).
- Click either tab to get started: Assistant or Talk to Human.
- Search Contact Us, then Start a chat with a support expert.
Please be guided as well of our Support hours. For Plus, Essentials, and Simple Start users, support is available from Monday through Friday from 6 AM to 6 PM PT and Saturday from 6 AM to 3 PM PT. For Advanced subscriptions, support is available any time and any day.
I've added an article to learn how to track your sales tax payments dues in QuickBooks: File your sales tax return and record sales tax payments in QuickBooks Online.
Please let us know if this works for you. I'll be waiting for your response!
