DESCRIPTION

This module will allow you to calculate the Canadian GST and PST charges on items.

There are several key processes:

CONSTRUCTING A TAX OBJECT

  my $tax = Business::Tax::Canada->new;

First, construct a tax object. There is no need to specify a list of provinces as all are supported.

PRICING AN ITEM

  my $price = $tax->item(
    from => $province_code,
    to => $province_code,
    $unit_price => $province_code);

You create a Price object by calling the 'item' constructor, with the seller's location (from), the buyer's location (to), and the unit price. From and to locations are used to determine if PST tax should be charged.

You must supply all values or you will receive an error.

CALCULATING THE COMPONENT PRICES

  my $price_to_customer = $price->full;
  my $gst_charged       = $price->gst;
  my $pst_charged       = $price->pst;
  my $tvq_charged       = $price->tvq;
  my $net_price_to_me   = $price->net;

Once you have the price, you can query it for either the 'full' price that will be charged (GST + PST if applicable), the 'gst' amount, the 'pst' amount, or the 'net' amount, which will be the same number you entered in the item method. tvq (Quebec's PST) is simply an alias to the pst method.
