Silverstripe Tax Admin

Adds ability to create and edit tax rates and categories in
the CMS (via siteconfig).

This allows for flexible tax configurations (meaning that
you can have tax rates for different countries, zones, etc).

You can then map these categories (or rates) to products,
line items (in invoices) etc and use them in your tax
calculations.

Assigning Taxes to Zones

By default this module integrates with the
GeoZones
module. This allows you to assign zones to TaxRate objects.
You can then use TaxCategory::getValidRate() to return the
most appropriate TaxRate for this category, based either on
the provided locale and zone, of the system default. EG:

use SilverCommerce\TaxAdmin\Model\TaxCategory;

// Get the tax category you want
$cateogry = TaxCategory::get()->byID(1);

// Find if we have a valid rate for Gloucestershire in the UK (GB)
$tax_rate = $category->getValidTax("GB", "GLS");
