Italian translation.csv for tax not working

Question

We have a Italian website on our Magento installation. All the translations are working from our theme's locale/it_IT/translate.csv file with the exception of "Tax","IVA". On the italian site Tax is being translated to Tasse which is the default Magento translation that seems to be coming from app/locale/it_IT/.

I've reviewed this excellent Magento Stackexchange answer on this topic but can't seem to get it to work.

The translation is not working on our checkout page or to be more specific our /it/onestepcheckout/index/ page.

I thought that maybe our translation was conflicting with another module, I'm not sure how to check which module it could be conflicting with, so I guessed it was a checkout module and updated my csv with:

"Tax","IVA"
"Mage_Checkout::Tax","IVA"
"Magestore_Onestepcheckout::Tax","IVA"

I also tried to check to see where the 'tax' string was being called from to check that it was being called throught the __() method but couldn't find it in a template. The closest I came was in the /onestepcheckout/onestepcheckout/review/totals.phtml template which has a method <?php echo $this->renderTotals('footer', $_colspan); ?>. Here is the template file in it's entirety:

<?php
 * @category    design
 * @package     base_default
 * @copyright   Copyright (c) 2010 Magento Inc. (http://www.magentocommerce.com)
 * @license     http://opensource.org/licenses/afl-3.0.php  Academic Free License (AFL 3.0)
 */
?>
<?php if ($this->getTotals()): ?>
<tfoot>
    <tr><td colspan="2">&nbsp;</td><td>&nbsp;</td></tr>
    <?php $_colspan = $this->helper('tax')->displayCartBothPrices() ? 3 : 2; ?>
    <?php echo $this->renderTotals(null, $_colspan); ?>
    <?php echo $this->renderTotals('footer', $_colspan); ?>
    <?php if ($this->needDisplayBaseGrandtotal()):?>
    <tr>        
        <td class="a-right" colspan="<?php echo $_colspan; ?>">
            <small><?php echo $this->helper('sales')->__('Your credit card will be charged for') ?></small>
        </td>
        <td class="a-right">
            <small><?php echo $this->displayBaseGrandtotal() ?></small>
        </td>
    </tr>
    <?php endif?>
    <tr><td colspan="2">&nbsp;</td><td>&nbsp;</td></tr>
</tfoot>
<?php endif; ?>

I also checked the core_translate table and it was empty, I made sure the cache was cleared and disabled. All the other translations from our theme's locale/it_IT/translate.csv file are working.

Any help or suggestions of where I should look would be really appreciated. Could I add the translation from the core_translate table

Answer 1

Finally found the issue, the core Mage_Tax module was conflicting my theme's translation.csv, I was able to overcome it by simply adding the below to my theme's locale/it_IT/translate.csv

"Tax","IVA"
"Mage_Tax::Tax","IVA"

Answer 2

Did you check in "Sales > Tax > Manage Tax Zones & Rates" ?

Here you can find your taxes title for each store view
