Charge only one tax from resellers

[harmeet]

Hi

I am from Ontario, Canada. Here we charge two taxes from end customers - GST (federal) and PST (provincial). But from resellers we only charge GST.

I have installed Dual Pricing mod on my site which allows me to show wholesale prices to resellers and retail price to end customers.

I have only one problem, on checkout, it adds both taxes to resellers.

What do I need to change to only charge GST from resellers?

Thanks

Did Anyone figure this out yet?

You'll need to write new code to exclude taxes from certain customers.

Thaks for replying, but I really am not sure how to do that.

Hi scully2569

I was not sure if anybody else needs this. I am not expert, but I managed to hack the code to my needs. Here is how I did it -

Please note that you need to have the "dual_pricing_1_3" module installed before making this change.

Open the file includes/functions/functions_taxes.php

Close to line 32, look for -

    $tax_query = "select sum(tax_rate) as tax_rate
                  from (" . TABLE_TAX_RATES . " tr
                  left join " . TABLE_ZONES_TO_GEO_ZONES . " za on (tr.tax_zone_id = za.geo_zone_id)
                  left join " . TABLE_GEO_ZONES . " tz on (tz.geo_zone_id = tr.tax_zone_id) )
                  where (za.zone_country_id is null
                  or za.zone_country_id = 0
                  or za.zone_country_id = '" . (int)$country_id . "')
                  and (za.zone_id is null
                  or za.zone_id = 0

Replace it with -

That is awesome, I will tackle that one soon!
Thanks for replying

[MB1]

sweet this must be the answer i have been looking for?

[fraso]

Now it seems that Zen Cart has some code that apparently works for wholesalers (Thanks Harmeet!), I'm going to seriously test how well this works for my needs. However, there is another download (Tax Exemption Status) that seems to be similar to the the modifed Dual Pricing module.

Has anyone set up a store for both retail and wholesale customers so that wholesale customers are exempt from paying provincial retail sales tax (in Canada)?

[fraso]

I see that the Dual Pricing - Wholesale Pricing download (modified with Harmeet's changes) allows a customer to be set up as a wholesale customer who is tax-exempt. However, the Tax Exemption Status download seems to do something similar.

I would like to set my store up as follows:

• retail prices shown to the general public.
• wholesale prices shown only to wholesale customers once they have logged-in.
• wholesale customers are exempt from paying provincial retail sales tax once they provide their tax exemption number.
• quantity-based discounts for wholesale customers and possibly also for retail customers.

What would be the best way to accomplish this?
