Question

I'm struggeling with this for a few days now.

I'm trying to sell products and insurances. Products have 19% VAT, insurances have 19% insurance tax.

I added a new Tax class, rate and rule.

enter image description here

If I see this correct, magento aggregates taxes with the same rate. There is no way to prevent this (at least I didn't found one)

\Mage_Tax_Model_Sales_Total_Quote_Tax::_totalBaseCalculation()

It doesn't matter what priority my rules has.

I'm ending with this, which is correct calculated, but not splitted in the correct parts:

MwSt. (19%)      21,70 $
Vst. (19%)       21,70 $
Tax              21,70 $

After adding shipping, it looks like this, now the sums are totally screwed:

MwSt. (19%)      22,50 $
Vst. (19%)       21,70 $
Tax              22,50 $

The interessting part is, the invoice in the backend is again ok (the pdf too):

Shipping & Handling Tax   0,80 $
MwSt. (19%)              15,97 $
Vst. (19%)                5,73 $
Total Tax                22,50 $

At the moment I think magento can't handle two different taxes with the same percent rate. At first glance, this use case isn't needed, but this evaluation is wrong :-/

Any ideas on this?

Was it helpful?

Solution 2

My current answer is: There is no way to have two tax settings with the same rate at the same time in the cart. The tax sum is always wrong.

In the invoice the calculation is correct...

OTHER TIPS

Magento 1.8 can't reproduce the issue.

Looks like as you want. Please contact with me, I think you have issues with configuration.

What country (is this common in Europe)? Why would you want a separate summary for insurance tax ( to remit for a refund or legal requirement )? I haven't tried yet - but have you tried CE 1.8.1; set a product tax class = Insurance; create an insurance rate/zone; create a tax rule (product tax class = Insurance; with insurance rate/zone; set sort to 1; select checkbox for calculate of sub-total). Does that work?

We see a similar issue

Suddenly there are 2 tax rates (whilst both are really 21%). Mage 1.8.1
