Taxer is a powerful module for calculating Value-Added Tax (VAT) in the cart and invoices, independent of OpenCart's built-in tax system. Designed for stores that require full control over VAT logic, this extension allows precise configuration of tax rates, calculation methods, and visibility rules.

The module can add VAT to the order total or extract VAT from amounts where it is already included. You can also limit VAT calculation to specific customer groups or geographic regions such as countries, zones, or geozones.

Key Features:

Custom heading for the VAT line in the cart and invoice
Selectable base for calculation: either Total (including shipping and fees) or Sub-Total (products only)
Two calculation methods:
[list]Calculate VAT – adds VAT to the total
Extract VAT – separates VAT from an already tax-inclusive amount

Conditional display of tax for specific customer groups
Apply VAT only in selected countries, regions, or geozones
Ability to show tax amount on the product page
Fully compatible with OpenCart 3.0.x.x series
Easy configuration from the admin panel[/list]

Module Variants (choose one during installation):

taxer.ocmod.zip – single VAT rate for all orders
taxer_by_regions.ocmod.zip – different rates for specific regions or states
taxer_by_countries.ocmod.zip – different rates by country
taxer_by_geozones.ocmod.zip – advanced control using OpenCart geozones

Whether you need to comply with VAT rules in the EU or other jurisdictions, Taxer provides a clean and flexible solution for accurate tax handling.
