Prices without tax included

Love the template. Trying to set a site up for business-to-business sales and want to show prices without tax, then add tax at checkout.
Can this be done whilst keeping the current styling?

Hi,
If you check our demo you will see that prices shown on product detalis or cateogry are without tax.

But can tax (VAT) then be added at checkout?

Tax is added in checkout. In cart you can see price,tax and total price(price+tax).
