Tax applied on Base Price But not on Final Price

[johanyohan]

I have this problem, if the product has a reduction price, the state tax is applied on the "base price" but not on the "final price", there's a problem with this in the shopping cart because the customer will see the final price with a tax based on the "base price" w/c is quite confusing for the customers to look at.

for example: state tax= 6.25%(0.0625)
base price = $100 <---- tax is applied here
reduction = $20
final price = $80 <-- tax is not applied here


upon purchase, the cart is showing 80$(final price) but the displayed tax calculation is $6.25(applied from the "base price") and not 5$(applied from the "final price"), its how its doing now. HOW CAN I MAKE THAT THE COMPUTATION FOR TAX WOULD APPLY FROM THE "FINAL PRICE" instead?

Any good hearts in here who can help me???

Having same problem and it is a big issue. Anyone solved this? This is not the way the taxes should be calculated!

PS attributes are set to INCLUDE tax already.

My Tax on a separate line Modification includes changes to make the impact Exclude tax.

I don't know how that works. I have been using your module for a while. It puts the tax separately but doesn't affect tax calculation when there is a discount. The tax is still applied to the initial price - not the discounted price.

I'm not sure about discounts, it affects the price impact of attributes.

I'll check out the discounts when I get a chance, what type of discount are you using?

This happens when someone uses a voucher. I even tested a 100% voucher and it applied tax to the initial price of the product. So, with $0.00 to pay for a product, a customer would still have to pay a tax.

Also looking for a fix for this. Using v.1.3.7 and not able to find a way to compute tax AFTER discount/voucher and BEFORE shipping costs. Any help would be much appreciated. Thank you.

That happens in /classes/Product.php in the function public static function getPriceStatic

You can try to lower the tax addition below the vouchers

       if ($usetax)
           $price = $price * (1 + ($tax / 100));

To under

       // Group reduction
       if ($usereduc)
           $price -= Tools::ps_round($price * Group::getReduction(((isset($id_customer) AND $id_customer) ? $id_customer : 0)) / 100, 2);

Thanks for the suggestion tomerg3. What version of Prestashop is the fix for? I tried looking in classes/Cart.php but couldn't find the suggested code.

I meant Product.php (not Cart.php) in public static function getPriceStatic(....)
