It says you can rename a tax agency but there are no instructions on how to do so and no obvious links. Has anyone successfully done this?

Thanks for reaching out here in the Community space, Diana.

If you're using the Auto Sales Tax feature in QuickBooks Online, the option you're trying to access is no longer available. Editing or renaming a tax agency is only available in the manual or old sales tax center. For more details, please see this handy article: Delete sales tax rates and agencies in QuickBooks Online.

On the other hand, here's an article to help you handle sales taxes inside the program: Set up your sales tax in QuickBooks Online.
