Prices Include Tax Option For Different Storefronts

Hi guys

I'm looking for a way to switch the 'prices include tax' on for one storefront and disable for another.

We have two shops; normal ( and wholesale (

The normal store should show prices with VAT and on checkout / invoice show ho much of the product is and how much vat is included.

On the wholesale store it should show the price ex vat and add the vat ass additional cost

Any one know of a way to do this or a plugin that can take care of this?
