doubles taxes?

[qwerty65]

hi,

 

I'm trying to setup osCommerce with just one taxzone for a dutch webshop. I've added one taxzone, one taxclass, one taxrate. When adding products I've selected the just added taxzone.

 

When I just browse through the products everything looks ok (i've set display prices with tax to true) but when I want to checkout the fourth page in the checkout (checkout_confirmation.php) show the productprices including VAT, but next to that it also has an additional line for the VAT:

 

Sub-Total:

115,78EUR

 

NL BTW 19%:

15,29EUR

(this one shouldn't be there as the productprice already included VAT)

 

Flat Rate (Best Way):

5,00EUR

 

Total:

120,78EUR

----------------

 

So the customer is billed for VAT twice.. Any idea how to fix this ?

 

I'd like to have the shop show the amounts including VAT and have one line on the invoice/overview that list the amount of VAT charged.

 

thanks,

I am having the same problem with all of my taxable customers in NC, USA.

 

Is there a setting that I'm missing?

It appears that I have figured out what went wrong with my situation. It appears to be a bug in the surepay.php payment module file.

 

Apparently, the module passed across the calculated total (the product, shipping, AND tax), but it also passed across a tax field to SurePay via...

 

            'taxamount'       => $HTTP_POST_VARS[ 'surepay_tax' ]

 

Therefore, though the customer sees the correct totals, even in their order email, when it comes across to SurePay, SurePay adds the tax again to the total.

 

I simply commented out the line above (around line 314) and it appears to have fixed the problem. I've recently seen a similar fix for the surepay module regarding double shipping costs.

 

I don't know if this is your situation, but it may be worth checking on, especially if you are using SurePay.
