Hi there, @kpagnotta. Let me share some details about automated sales tax.

Once you turn on the automated sales tax feature in QuickBooks Online (QBO), turning it off is not an option. As a workaround, you can make the items not taxable and set customer as tax-exempt.

To make items into non-taxable, here's how:

1. Go to the Gear icon at the top.
2. Select Product and services. 
3. Locate the taxable item you want to change to non-taxable by clicking Edit under the Action column.
4. Go to the Sales tax section, and click on Edit sales tax.
5. Select Nontaxable.
6. Click Done, then Save and close.

To make a customer into tax exempt:

1. In the left menu, click Sales.
2. Go to the Customers tab.
3. Locate and click the customer's name.
4. In the Customer Details tab, click the Edit button.
5. In the Additional info section, put a checkmark for This customer is tax exempt.
6. Click Save.
