Hi debdeb1.
Being able to customize your estimates to show the information you want is one of the ways QuickBooks Desktop helps you add your own personal touch. I'd be happy to help you with removing the sales tax line.
Modifying your template is the best way to remove or add sections on your estimates. In order to modify your template to remove the sales tax option I recommend following the steps in this article. You can also use that article to make a custom estimate template as well that you can import and use.
If you have any questions let us know and we'd be happy to help.
