Hello there, @ASHLEY_512.
Let me provide a few information on how the sales tax center works.
At this time, the option to delete a sales tax is unavailable QuickBooks Online (QBO). However, you can change its status to inactive. From there, you'll no longer receive notifications about it. Here's how:
- Go to Taxes from the left menu, select Sales Tax.
- Click the Sales tax settings link.
- From the Action column, click the Edit drop-down arrow.
- Hit Make inactive.
You can visit this blog for more detailed information: Sales Tax in QuickBooks Online.
Just in case you wanted to set rules for how to tax a product or service, you can refer to this article: Add sales tax categories to your products and services.
Keep me posted if you have more questions. I'll keep my notifications open. Stay safe and well!
