Free sales tax software for windows

Calculates American sales taxes, state and district.
Java Applet that can also be run as an application.
Requires Java version 1.5 or later.
Java source code and sample HTML included.
This version computes by adding sales tax to a base price.
It also works in reverse given the total paid working
backwards to get the tax and original price. In other words
it will tell you the sticker price to make something come
out even after taxes are added. It also has a spinner that
lets get that result without typing.
Just select the buyers state and district, enter the amount
of the sale and hit calc. You can adjust the sale amount
with a spinner.
If you are a business, you dont have to collect sales taxes
from people in other states unless you have a business
presence in that state. In that case, you must collect just
the state tax, not the local tax.
The program splits out the state and local taxes so that if
you have a business presence in his state, you can tell him
the amount he must remit to you (the state part) and the
part he must remit voluntarily and directly (the local
district part).
