open cart tax issue

Question

I'm new to Opencart. In fact I'm working in my first project that is in Opencart 2.3.0.2. It's almost done.

Now the client need the price of a product should be inclusive of tax.

now actually it's working like the tax is added with unit price. I need it to be included.

ex: Rs.100 (includes GST 18%)

incorrect:
Unit Price: 100
GST@18%: 18
Total: 118

Correct:
Unit Price: 84.75
GST@18%: 15.25
Total: Rs.100

instead of 100*18/100, we need to calculate 100*100/118 (100*100/118)-100 to get GST

Answer 1

Go to Admin->System->Settings, edit your Store, and select the Option tab. There is a setting called "Display Prices With Tax."
