Hello there, @jana-tuckerman.
Great to see you here in the Community. Let me share some information about editing the sales tax rate in QuickBooks Online.
In the new sales tax feature, we calculate your sales tax through this information:
The state where you have nexus and are registered to collect sales tax.
The physical address of your business and on the sales receipt or invoice.
The product mapping you have associated with the products or services you are selling.
The exemption status of your customer.
With that being said, we're unable to change the edit tax rate. You can check out our help article: Set up and use automated sales tax. It helps you learn how the new automated sales tax experience in QuickBooks Online.
Feel free to message us again if you have follow-up questions. We're always delighted to help.
