I believe in being proactive.  Many of you in Wilmington NC may be dealing with the new 8% sales tax rate in New Hanover County.  Here is how you change the rate in Quickbooks:

Go to the Item List.
Find the current Sales Tax item.
Double-click.
Change the Rate.
This will not effect past entries of Sales Receipts or Invoices.
Verify that the rate is correct in a new invoice.
