Registered automatically by registerAllPlugins() (via registerSwissTaxPlugins() from @unchainedshop/plugins/presets/countries/ch).

Registration

import { pluginRegistry } from '@unchainedshop/core';
import { ProductSwissTaxPlugin } from '@unchainedshop/plugins/pricing/product-swiss-tax';

pluginRegistry.register(ProductSwissTaxPlugin);

How It Works

1. Checks if the delivery address is in Switzerland or Liechtenstein
2. Determines the tax category from:
   • Product tags (e.g., swiss-tax-category:reduced)
   • Delivery provider configuration
   • Falls back to DEFAULT (8.1%)
3. Calculates and adds tax amounts to the pricing sheet

Tax Categories

Category	2024+	2018–2023	2011–2017	2001–2010	Use Case
DEFAULT	8.1%	7.7%	8.0%	7.6%	Standard goods and services
REDUCED	2.6%	2.5%	2.5%	2.4%	Food, books, newspapers, medicines
SPECIAL	3.8%	3.7%	3.8%	3.6%	Accommodation services

The rate is selected by the order date (supply date), so historical recalculations stay era-accurate.

Rate Data

Rates are bundled in ch-tax-rates.json as era lists ({ validFrom, rate }), verified against the ESTV. Rates are never fetched at runtime — updates land as reviewed diffs via the repository's update-tax-rates skill.

Configuration

Via Product Tags

Add a tag to the product:

swiss-tax-category:reduced
swiss-tax-category:special

Via Delivery Provider

Configure the delivery provider:

mutation CreateDeliveryProvider {
  createDeliveryProvider(
    deliveryProvider: {
      type: SHIPPING
      adapterKey: "shop.unchained.post"
    }
  ) {
    _id
  }
}

mutation ConfigureDeliveryProvider {
  updateDeliveryProvider(
    deliveryProviderId: "provider-id"
    deliveryProvider: {
      configuration: [
        { key: "swiss-tax-category", value: "reduced" }
      ]
    }
  ) {
    _id
  }
}

Net vs Gross Prices

The adapter handles both net and gross prices:

• Net prices: Tax is added on top (amount * taxRate)
• Gross prices: Tax is extracted from the total (amount - amount / (1 + taxRate))
