Unfortunately, Oracle has effectively decommitted Applets. This means you can no longer run the various CMP programs in a browser. You must download them and install them.
You must have the most recent Java
JRE (Java Runtime Environment) 1.8.0_131
32-bit or 64-bit. It no longer matters which browser you use.
Oracle has effectively decommited Applets, so this Applet will no longer run online in your browser, but it is a hybrid you
can also download, install and run it on your own machine as standalone
application. It will start and run faster if you do that. It will also
work safely even if you have disabled Java in your browser.
American sales taxes are complicated to the point of comedy. One of the odd features
is sometimes the vendor remits the tax and sometimes the buyer is supposed to do it.
However, in practice nearly all buyers forget to. For large
ticket items, like yachts, the vendor always collects and remits the tax. For smaller
items, the vendor only collects the tax if the buyer is in the same district.
If you are a business, you don’t 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.
After 12 years, the program is finally complete. It now
handles sales taxes for all American states, counties and cities. The task now is to
correct errors and keep it up to date. If you see any errors, omissions or out of date
information, please let me know.
American sales taxes are preposterously complicated. Every town can have a different
rate, every county and every state. Visitors to a town have no idea what to expect. The
rates are not posted in standard format anywhere on the Internet in computer-readable
format. Every state provides the information in a different computer-hostile way. In many
cases I had to guess what the tax rate was, making a lawyerly call on some obscure
explanation. Businesses may have to remit sales taxes to three different
bureaucracies.
I hope someday the feds do an honest taxes
measure where all federal, state and local taxes must be posted in standard
computer-friendly format so that your cell-phone can accurately compute the sales or any
other tax.
To check the rates, just enter a sale amount of $100.00
and the tax amounts will equal the percentages.
If you notice any errors, please let me know.
The calculator is also available with Java source to download. It is designed to be cannibalised, so that
you can use whatever parts of the calculator source code you want in your own code, e.g.
a shopping cart. There are notes in the source on precisely how the taxes are
calculated.
Java Requirements and Troubleshooting
AmericanTax
is a signed Java Applet (that can also be run as an application)
to American Sales Tax Calculator.
You are welcome to install it on your own website.
If it does not work…
For this Applet hybrid to work, you must click grant/accept/always run on this site/I accept the risk
to give it permission to let you copy/paste.
If you refuse to grant permission, the program may crash with an inscrutable stack dump
on the console complaining about AccessController.checkPermission.
In the Java Control Panel security tab,
click Start ⇒ Control Panel ⇒
Programs ⇒ Java ⇒ Security, configure medium security
to allow self-signed and vanilla unsigned applets to run.
If medium is not available, or if Java security is blocking you from running the program,
configure high security
and add http://mindprod.com
to the Exception Site List at the bottom of the security tab.
Often problems can be fixed simply by clicking the reload button on your browser.
Make sure you have both JavaScript and Java enabled in your browser.
Make sure the Java in your browser is enabled in the security tab of the Java Control panel.
Click Start ⇒ Control Panel ⇒
Programs ⇒ Java ⇒ Security ⇒
Enable Java Content in the browser.
This signed Java Applet (that can also be run as an application)
needs 32-bit or 64-bit Java 1.8 or later.
For best results use the latest 1.8.0_131 Java.
It works under any operating system that supports Java
e.g. W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, W10-32, W10-64, Linux, LinuxARM, LinuxX86, LinuxX64, Ubuntu, Solaris, SolarisSPARC, SolarisSPARC64, SolarisX86, SolarisX64 and OSX
You should see the Applet hybrid above looking much like this
screenshot.
If you don’t, the following hints should help you get it working:
If the above Applet hybrid appears to freeze-up, click
Alt-Esc repeatedly to check for any buried permission dialog box.
If you have certificate troubles,
check the installed certificates
and remove or update any obsolete or suspected defective certificates.
The only certificate used by this program is mindprodcert2017rsa.cer.
Especially if this Applet hybrid has worked before, try clearing the browser cache and rebooting.
To ensure your Java is up to date, check with Wassup.
First, download it and run it as an application independent of your browser,
then run it online as an Applet to add the complication of your browser.
If the above Applet hybrid does not work,
check the Java console for error messages.
If the above Applet hybrid does not work, you might have better luck with the downloadable version available below.
If you are using Mac OS X and would like an improved Look and Feel,
download the QuaQua look & feel
from randelshofer.ch/quaqua.
UnZip the contained quaqua.jar
and install it in ~/Library/Java/Extensions
or one of the other ext dirs.
Upgrade to the latest version of Internet Explorer or another browser.
Click the Information bar, and then click Allow blocked content. Unfortunately, this also allows dangerous ActiveX code to run. However, you must do this in order to get access to perfectly-safe Java Applets running in a sandbox. This is part of Microsoft’s war on Java.
Try upgrading to a more recent version of your browser,
or try a different browser e.g. Firefox, SeaMonkey, IE or Avant.
If you still can’t get the program working
click the red HELP button below for more detail.
If you can’t get the above Applet hybrid working
after trying the advice above and from the red HELP button below,
have bugs to report or ideas to improve the program or its documentation,
please send me an email at.
