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.

Tables are complete for the following states:
AK, AL, AZ, CA, CO, CT, DC, DE, FL, GA, HI, IL, IN, KY, MA, MD, ME, MI, MN, MO, MS, MT, NC, NH, NJ, NY, OH, OR, PA, RI, TN, TX, VA, VT, WA, WI, WV.

It knows all state level taxes.

Tables still need to be added to deal with local taxes for the following states:
AR, IA, ID, KS, LA, ND, NE, NM, NV, OK, SC, SD, UT, WY.

If you have the information, please pass it along.

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. Sorry, you need Java 1.5+ to run this Applet.

If, americantax, the above American Sales Tax Calculator Java Applet (that can also be run as an application) does not work…

  1. This Java Applet (that can also be run as an application) needs Java 1.5 or later, best version 1.5.0_22 or later, version 1.6.0_17 recommended and a recent browser.
  2. You should see the Applet hybrid above looking much like the screenshot. If you don’t, the following should help you get it working:
  3. If you are using Microsoft Internet Explorer, try another browser. Seriously. Microsoft has taken great pains, over and over, to screw up Java and every other multi-platform standardisation.
  4. If you are using Internet Explorer 7 or 8, you must allow blocked content permission for Active X to run. This also gives permission to Java to run. 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. Don’t put up with it! Use a different browser.
  5. Especially if this Applet hybrid has worked before, try clearing the browser cache and rebooting.
  6. 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.
  7. If the above Applet hybrid does not work, check the Java console for error messages.
  8. If the above Applet hybrid does not work, you might have better luck with the downloadable version.
  9. 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.
  10. If you still can’t get the program working click HELP for more detail.
  11. If you can’t get the above Applet hybrid working after trying the advice above and from the HELP button below, have bugs to report or ideas to improve the program or its documentation, please send me an email atemail Roedy Green.
