Hi, I did a quick and not integrated solution when I couldn't get the Tax exemption module working and I realized that it just basically subtracted the tax.
I will take a look at your Mod when I get time numinix, it sounds like what I am looking for.
Anyway, with the realization that the module is just basically subtracting the tax amount, this is what I did.
I created a "group pricing" under customers called PST exempt and made the discount 7% (BC PST)
When I get a customer who is PST exempt I add them to the PST exempt group and it gives them a 7% discount called "PST exempt"
And last but not least, I changed "Fax number" to "Tax number" everywhere in the files and I can collect the tax number when they set up the account. I Ithink I moved it to show up under "additional contact information" (I don't require Fax numbers so it worked for me)
I have edit order working on my site, so I just go in to their first order and subtract 7% and name it PST exempt. After I move them to the pricing group, they just automatically tax exempt.
I have been setting up my site for a long time (has months turned to over a year) as i have a lot of product, so I haven't really been able to test this except with test orders I create, so I am not sure if there is anything I didn't think of, but it works for now.
I am looking for something that actually removes the tax rather than subtracts it, but up to now I have not seen anything that works.
hth, Pat
