Tax Settings

HI

In the UK when selling an item to the general public the price has to be displayed including the vat on the product you are selling.

the problem we have is that if we use the tax options in ST the tax is not added until checkout, so the price on the listing page is excluding tax.

Can any one guide us how we can get the product listing to show inc vat then the checkout page to itemise vat on the sale,

thanks
