Hi,
The product prices in the HikaShop backend are displayed without taxes unless you're using the "floating taxes" setting.
And it is the same thing in the HikaMarket front-end.
To display a product with taxes, you need to use an address (at least a country) in order to use the right tax rules.
That's why the prices without taxes are stored in the database and why the price with tax is processed dynamically.
If you want to display product prices with taxes in the vendor product listing ; you'll need to perform an override of the view and force the processing of the taxes to display the prices.
