# Taxes & Tax Mapping

Correct tax mapping is a prerequisite for error-free prices and orders. The connector links the BC **VAT Product Posting Groups** with the Shopware **tax rates**.

**Basic principle**

```mermaid
flowchart LR
    A[VAT Product Posting Group in BC] --> B[Item Tax Mapping]
    B --> C[Shopware tax rate taxId]
    D[Item] -->|refers to| A
    D -->|Upload| C
```

During the item upload, the connector uses the item's VAT Product Posting Group to determine the matching Shopware tax rate (`taxId`). If no mapping exists, the **default tax ID** from the configuration is used.

**Setup**

{% stepper %}
{% step %}
**Load taxes**

Use [Load Shopware Initial Data](/shopware/shopware6_en_us/configuration/load-shopware-initial-data.md) to import the Shopware tax rates and tax rules.
{% endstep %}

{% step %}
**Maintain the item tax mapping**

In [Shopware Assignment & Mapping](/shopware/shopware6_en_us/configuration/shopware-assignment-and-mapping.md) (module *Item Tax Mapping*), assign the matching Shopware tax ID to each VAT Product Posting Group.
{% endstep %}

{% step %}
**Set the default tax**

Enter a **default tax ID** in the configuration as a fallback.
{% endstep %}
{% endstepper %}

**Tax-exempt products & order tax**

* A separate **tax-exempt group** can be defined for **tax-exempt** products.
* For orders, the settings **Use VAT**, **VAT Business Posting Group** and **VAT Product Posting Group** determine how taxes are calculated on the document. For details, see [Order Configuration](/shopware/shopware6_en_us/configuration/basic-settings/order-configuration.md).

{% hint style="warning" %}
Check the tax mapping **before** the first large item upload. Otherwise, an incorrect mapping will result in incorrect prices in the shop.
{% endhint %}

{% hint style="info" %}
Use the **Reset VAT Mapping** action in the configuration to rebuild the tax mappings if required.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.solutioo.de/shopware/shopware6_en_us/configuration/taxes-and-tax-mapping.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
