[solved] Apply specific price before adding tax

[vasikgreif]

Is there a way to apply amount based specific price before the tax is applied? I mean

 

Product price $10 => discount $2 = $8 => with 10% tax $8.8

 

instead of 

 

Product price $10 => with 10% tax $11 => discount $2 => total $9  

 

I found many threads about this issue, and didn't find any solution.

Thanks for the link! I think I have it working on PS 1.6. 

 

In Product.php I changed the line

$specific_price_reduction = !$use_tax ? $product_tax_calculator->removeTaxes($reduction_amount) : $reduction_amount;          

to 

$specific_price_reduction = floatval($reduction_amount);

I also had to switch the product price display under Customers - Groups to "Tax ecl.", as without that the tax got calculated wrong.

 

The last thing I did was commenting following line in themes/default-bootstrap/js/product.js, to display the price correctly on tyhe products page

 

//$('#our_price_display').text(our_price);

I have to test this solution more, to confirm it's really fully working.

This is not solved - commenting out the line in product.js leads to combinations not working. Anyone can point me to what to change in the product.js to make this work correctly?

This works for v1.6.0.9

 

In classes/product.php

 

Found on line 2761

 

Change:

$specific_price_reduction = !$use_tax ? $product_tax_calculator->removeTaxes($reduction_amount) : $reduction_amount;

 

To:

$specific_price_reduction = $reduction_amount;
