This extention adds another new panel (Sales Tax) to the built-on Formulas application. This panel has fields for Total Sale, Sales Tax Rate, Tax Amount and Total with Tax. If you enter any two of these values, the remaining two will be calculated for you. This panel can also optionally remember the last sales tax rate used.
NOTE: If you installed the 1.0 version, which was named Sales Tax Formula, you must scrub it from the Extras Drawer before installing later versions.
