How to have product price with tax show but without calculating it?

[GixxerMKD]

Hi guys,

i'm pulling my hair out from what it seemed like an easy thing to do. I've searched the forum and googled it but i can't find an answer.

Example: i've put 1800 in cost price, choose discount of -500 and on the frontend, the product details shows striketrough price of 1800 and new price of 1300 ('ive added the proper css to the classes), which is just what i want.

Now the problem is that i want to show on the bill (on the cart page) that those 1300 have calculated vat of 5% or 18% (we have different vat for different products).

Is there a simple way i can achieve this?

p.s. i've tried adding tax in "Tax & Calculation Rule" but it adds it to the final price (ie. 1300 price +18% makes it 1624)
