Taxes missing at all?

[papillon6]

Hi yvoronoy,

i think i found a bug. The extra fee is just added "on top" of all costs, without respecting taxes. Here a short example.
First without extra fee - standard functions of magento:

subtotal (without tax): 10€
shipping (without tax): 5€
/---------------------------------
tax (19%): 2,85€
/---------------------------------
total (including tax): 17,85€

Now i add an extra fee of 5€. What your extension does:

subtotal (without tax): 10€
shipping (without tax): 5€
/---------------------------------
tax (19%): 2,85€
extra fee: 5€
/---------------------------------
total (including tax): 22,85€

That's obviously wrong, because the extra fee is calculated without any taxes.
What it should do:

subtotal (without tax): 10€
shipping (without tax): 5€
extra fee (without tax): 5€
/---------------------------------
tax (19%): 3,80€
/---------------------------------
total (including tax): 23,80€

Did i miss a configuration-option?

Regards!

Hi @papillon6
Thank you for reporting this issue.

I think we should add configuration to choose needed behaviour.
Since at now taxes doesn't respect extra fee at all.

The Problem here is the sorting, Magento is a bit buggy here.
I also made an Fee Extension which had the same problem.
It could be easy fixed by changing
<.after.>subtotal</.after.>
<.before.>grand_total</.before.>
In the config.xml.

You have to play a bit with the values. Multiple values could be needed and could be used by "," as separator. E.g.
<.after.>nominal,subtotal</.after.>
<.before.>grand_total</.before.>

Take a look into sales config for examples:
app\code\core\Mage\Sales\etc\config.xml

Well as I figured out, this will only fix the tax usage in general, but not the tax calculation for the fee amount. For this it seems you have to add the tax in the collect method, which worked for me so far. Maybe there is a better way.
I did it similar to here: app\code\core\Mage\Tax\Model\Sales\Total\Quote\Tax.php

Any news on this problem?

Actually there is no solution yet @crysix
You are welcome for pull requests if you have solution.

Hi Yvoronoy,
that's a very interesting module but unfortunatelly it is crashing my front end (back end ok).
Is it compatible with Magento 1.7?
Thank you

Is there a way to add the proper amount to the taxes and the total so that calculations are correct? Right now the extra fee is like a totally separate amount added to the total and does not respect any taxes, which creates problems with various payment processors (e.g. I'm personally having problems with myPos).
