Tax - Canada

[kovacshazi]

Incorrectly calculated the tax value of the OPC

My TAX settings:
American settings: YES
Product unit price at checkout: CANADIAN
Subtotal at the checkout: CANADIAN
Coupon price at the checkout: whitout Tax
Plugin Discounts: NO
...
Show just one tax: NO
Show dynamic lines: YES

If "show just one tax" - is checked, the VAT calculation good
If "show just one tax" - is unchecked, the VAT calculation false.

hello, opc does not calculate the tax, it can only alter a different views of the tax itself.

i suggest to check your tax config from within virtuemart's calculations. there is a huge difference between calculating tax for "eu vat tax" and "canadian sales tax". In some cases the tax in US/Canada can be calculated before it's discounted.

in general you also may want to try to set all payment and shipping methods "to use no tax" and see if this fixes the problem.

hello, i just did a test on my demo on vm3.0.8 and i see the same problem, i am going to check on when did this behavior changed and see if this is a VM bug or OPC bug.

For this product there is no discount.
If the OPC is used then the TOTAL is good, so VAT is good.
A dynamic calculatd TAX value is false.

hello, i did further tests and i found that:
- when using "Bill Tax" the opc and VM should generate the lines properly
- but when using "tax per product" there is no summary within VM where opc could pick up the proper rate (or i have to create a work around for latest VM releases, am trying to consult with VM team if this is intentional or not... )

so you can fix this with two options:
- either change the tax to Bill Tax or try Vat Tax if it calculates the rate properly (i didn't yet tried vat tax)
- or keep the single line within OPC's config, so it summarizes the taxes (this is how the new default cart looks in VM as well)

hello, i located the issue within opc code that prepares the line tax display. this type of tax display is not available in core VM, so opc indeed does a calculation from VM's values to show each tax individually if needed. the issue is caused by a small change in VM's objects property where opc incorrectly gets the rates.

to fix this issue, you can either update to our dev version (upon request) or you can just comment one line within
\components\com_onepage\helpers\ajaxhelper.php

locate and comment this line:

Code: Select all

if (!empty($results) && (!array_key_exists($k2, $results)))


so it looks like:

Code: Select all

// if (!empty($results) && (!array_key_exists($k2, $results)))


i will also send you an update by email.
