# VAT Group Affiliation (Organschaft)

## Business Value

In a VAT group (Organschaft), the turnover of all member companies is consolidated and reported to the tax authorities under a single tax number at the group parent level. With 365 business ERiC, companies map this VAT group affiliation directly in Microsoft Dynamics 365 Business Central — without an additional app and without manually consolidating the values from the individual companies.

## Feature Description

365 business ERiC implements VAT group affiliation itself. It is configured per company in the **ELSTER Setup** using the **Affiliation Code** and **Affiliation Parent Company** fields. All companies of the VAT group share the same **Affiliation Code**; exactly one company is flagged as the **Affiliation Parent Company**.

When calculating the Sales VAT Advanced Notification and the Permanent Time Limit Extension in the parent company, 365 business ERiC automatically includes all member companies and consolidates their values at the group parent level.

The **cross-company entry drill-down** makes the reported values fully traceable: the **Entries** action on a tax data line displays the underlying VAT Entries from all companies of the VAT group in a single view, including the company each entry originates from.

_**Note:** Up to and including version 17.13, VAT group affiliation was based on OPplus. That implementation has been superseded as of version 17.14._
