Hello, @debbie170.
To resolve this matter, you’ll need to assign tax agencies and set up tax codes. If this setup is missing or incomplete, the Tax rate dropdown won’t display selectable rates and will instead direct you to Manage Rates.
To guide you in finishing the setup, you can follow these steps:
- Open your QuickBooks Online account.
- Go to Taxes and select Sales tax.
- Click the Manage Sales tax.
- Hit the Add tax and then follow the on-screen prompt.
- Please ensure that any tax rates you add are set to Active.
Once you're done setting up your sales tax, you'll be able to make the Select tax dropdown work. If you have other questions, please don't hesitate to click the Reply button, and we'll be right here to help you any time.
