Help with Tax configuration


Recommended Posts



I need some help setting up the tax calculations.


Idaho charges 6% ST Tax, and Kootenai County adds another .5%.

Tests from within my county, inside the state, and out of state are charging both taxes. Is there a module that will check a list of zip codes for the county?

And why is it charging the ID tax for other states?


I am new to osCommerce and this forum, but not to news groups.

I am not a newbie. I've read the installation docs (wiki), searched the archives, and followed a few threads here.


I would appreciate a hint. Is there another FAQ, more docs, sample code, etc.?

I've only dealt with in & out of state tax, but in trying to set that up, I found lots of useful support & contributions, many of which dealt with county & zip code taxes. You can view a list of potential contributions here:




The zone tax stuff gets pretty convoluted (set up a tax zone & edit it, go to the regional zone & add the tax zone... I can't remember), but I found one lengthy step-by-step in these forums very useful... ah, there it is:




Again, I haven't stalled the by-county or by-zip tax contributions, but I expect they're set up using the standard make-the-zone/assign-the-zone process.


I hope this helps -
