SYNOPSIS
     use Business::Tax::VAT;

     my $vat = Business::Tax::VAT->new(qw/uk ie/);

     my $price = $vat->item(120 => 'ie');
     my $price_to_customer = $price->full;     # 120
     my $vat_charged       = $price->vat;      #  20
     my $net_price_to_me   = $price->net;      # 100

     my $price = $vat->business_item(100 => 'uk');
     my $price_to_customer = $price->full;     # 117.5
     my $vat_charged       = $price->vat;      #  17.5
     my $net_price_to_me   = $price->net;      # 100

DESCRIPTION
   Charging VAT across the European Union is quite complex. The rate of tax
   you have to charge depends on whether you're dealing with consumers or
   corporations, what types of goods you're selling, whether you've crossed
   thresholds in certain countries, etc.

   This module aims to make some of this simpler.

   There are several key processes:

CONSTRUCTING A VAT OBJECT
 new
     my $vat = Business::Tax::VAT->new(@country_codes);

   First of all you have to construct a VAT object, providing it with a
   list of countries for which you have to charge VAT. This may only be the
   country in which you are trading, or it may be any of the 15 EC
   territories in which VAT is collected.

   The full list of territories, and their abbreviations, is documented
   below.

PRICING AN ITEM
 item / business_item
     my $price = $vat->item($unit_price => $country_code);
     my $price = $vat->business_item($unit_price => $country_code);

   You create a Price object by calling either the 'item' or
   'business_item' constructor, with the unit price, and the country to
   which you are supplying the goods. This operates on the priciple that
   prices to consumers are quoted with VAT included, but prices to business
   are quoted ex-VAT.

   If you do not supply a country code, it will default to the first
   country in the country list passed to VAT->new;

CALCULATING THE COMPONENT PRICES
 full / vat / net
     my $price_to_customer = $price->full;
     my $vat_charged       = $price->vat;
     my $net_price_to_me   = $price->net;

   Once we have our price, we can query it for either the 'full' price that
   will be charged (including VAT), the 'net' price (excluding VAT), and
   the 'vat' portion itself.

NON-VATABLE COUNTRIES
   If you send goods to many countries, some of which are in your VAT
   territory and others not, you can avoid surrounding this code in
   conditionals by calling $vat->item on all items anyway, listing the
   country to which you are supplying the goods.

   If the country in question is not one of the territories in which you
   should charge VAT then the 'full' and 'net' values will be the same, and
   'vat' will be zero.

NON-VATABLE, ZERO-RATED, REDUCED-RATE GOODS
   This module does not cope with goods which are not at the 'standard'
   rate of VAT for a country (as detailed below).

   Patches welcomed!

COUNTRIES AND RATES
   This module uses the following rates and codes:

     at, Austria, 20%
     be, Belgium, 21%
     cy, Cyprus, 15%
     cz, Czech Republic, 19%
     dk, Denmark, 25%
     ee, Estonia, 18%
     fi, Finland, 22%
     fr, France, 19.6%
     de, Germany, 16%
     gr, Greece, 17.5%
     hu, Hungary, 25%
     ie, Ireland, 21%
     it, Italy, 20%
     lv, Latvia, 18%
     lt, Lithuania, 17.5%
     lu, Luxembourg, 15%
     mt, Malta, 18%
     nl, The Netherlands, 19%
     pl, Poland, 22%
     pt, Portugal, 21%
     sk, Slovak Republic, 19%
     si, Slovenia, 20%
     es, Spain, 16%
     se, Sweden, 25%
     uk, United Kingdom, 17.5%

   If any of these rates become incorrect, or if you wish to use different
   rates due to the nature of the product (e.g. books are 0% VAT in the
   UK), then you can (locally) set the rate by assigning to
   %Business::Tax::VAT::Price::RATE. e.g.:

     local $Business::Tax::VAT::Price::RATE{uk} = 0
       if ($product_type eq 'book' and $country eq 'uk');
