How do I create a zip code to be exempt from VAT being added?

I need to make it so that pick up orders or orders shipping to 85200 zip code does not get VAT added. We're in a very small island in the Southern Aegean and we allow prices for items placed online that either ship to someone one the island or if they select pickup order in-store to not be charged VAT. Currently, I issue refunds but it tends to stop people from shopping since most of us don't like being charged even though we get refunded...

Unfortunately, VAT is not zip code specific. The best option may be to update the tax via template code on OPAY to zero it out if they are in the certain zip codes.

as additional info, you'll want to run:

<mvt:if expr="g.basket:shipping_zip EQ '12345'">
<mvt:do file="g.Module_Root $ '/modules/tax/vat.mvc'" name="l.success" value="VAT_Delete(l.settings:group:id)" />
</mvt:if>
In the basket loop of OSEL (and maybe OPAY and INVC)
