PrestaShop v.1.4+
PrestaShop taxes not working in the product page, when user enters ‘Pre-tax retail price’ and selects the ‘Tax rule’, nothing changes in the Back Office or Front Office of PrestaShop.
Step 1.) Confirm that you have enabled the feature to display tax in the Back Office as ‘tax included’: BO > Customers > Groups
If that did not resolve your taxes from displaying, then go on to step two.
Step 2.) Go to theme and edit product.tpl
Line 256
{if $tax_enabled && ((isset($display_tax_label) && $display_tax_label == 1) OR !isset($display_tax_label))}
{if $priceDisplay == 1}{l s=’tax excl.’}{else}{l s=’tax incl.’}{/if}
{/if}
Replace with..
{if $tax_enabled && ((isset($display_tax_label) && $display_tax_label == 1) OR !isset($display_tax_label))}
{if $priceDisplay == 1}{l s=’tax excl.’}{else}{l s=’tax incl.’}{/if}
{/if}
Line 275
{if $tax_enabled && $display_tax_label == 1}
{if $priceDisplay == 1}{l s=’tax excl.’}{else}{l s=’tax incl.’}{/if}
{/if}
Replace with..
{if $tax_enabled && $display_tax_label == 1}
{if $priceDisplay == 1}{l s=’tax excl.’}{else}{l s=’tax incl.’}{/if}
{/if}
Don’t forget to recompile your smarty template after editing any .tpl file in the Back Office.
