NAME ^

Business::Tax::VAT - perform European VAT calculations

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');
