Good evening, @mikefinleyco.
Thanks for posting your question here. I'd be happy to provide insights about commuting sales tax automatically based on the customer's address.
At this time, QuickBooks Desktop doesn't offer a feature that bases the sales tax automatically off of a customer's address. I can see how this feature would be helpful to you and your business. I will send this feedback on your behalf so our developers will be aware of how we can improve your QuickBooks Desktop experience.
For now, In QuickBooks Desktop you can set up different sales and apply them. There's a default one you can choose in the Preferences section. You can refer to this article as it has detailed instructions with setting with sales tax: Set up sales tax in QuickBooks Desktop.
Feel free to comment below if you have any more questions or concerns. Have an excellent rest of your day!
