Tax Classes for TastyIgniter v4

Per-item VAT tax classes for countries with a split VAT rate — built for Germany (7% reduced for takeaway/delivery food, 19% standard for drinks), works for any two-rate scheme (Ireland 13.5/23, Belgium 6/21, …).

TastyIgniter core supports a single global tax rate. This extension replaces it with two inclusive tax lines, each computed from the gross prices of the items in its class:

Prices stay gross (tax is back-calculated and never added on top), totals are rounded once per class, and the two lines are persisted as separate order totals — so they appear in the cart, at checkout, on invoices and in order mails automatically.

Features

• Two tax classes (reduced / standard), rates configurable — defaults 7% / 19%
• Assign a class per menu item, per category (items inherit), or fall back to a configurable default class
• Correct German gross handling: back-calculated inclusive VAT, per-class rounding
• Delivery charge taxed in a configurable class (default: standard rate)
• Zero theme changes needed — uses standard cart conditions and order totals

Installation

1. Install the extension (marketplace or extensions/iamnothardcoded/taxclasses/), then run php artisan igniter:up to add the tax_class columns.
2. Disable the core VAT condition — otherwise you get a third, wrong tax line: Admin → Settings → Cart Settings → Cart Conditions tab → toggle "VAT" off. Leave "VAT reduced rate" and "VAT standard rate" enabled (they are by default).
3. Set your rates and defaults under Admin → Settings → Tax Classes.
4. Tag your categories: typically set the drinks category to Standard and leave everything else on the default class (Reduced). Individual items can override their category on the menu item form (General tab → Tax class).

Notes & limitations

• Item in several categories with different classes: the first classed category wins. Set the class on the item itself to be explicit.
• §19 UStG (Kleinunternehmer) / no VAT display: disable both tax-class conditions in the Cart Conditions tab — no tax lines are shown anywhere.
• Coupons: v1 computes VAT from the items' gross subtotals; a cart-level coupon does not reduce the VAT base proportionally.
• PayPal: the itemized tax field in PayPal's order breakdown (populated only for a condition literally named tax) stays empty. Charged amounts are correct.
• Your fiscal system (e.g. TSE-Kasse) remains authoritative for tax reporting; this extension makes the shop's displayed and recorded totals match reality.
