Since July 2021 mail order and service sales within the EU with individuals and entrepreneurs without a UID number are taxable from the first euro in the destination country. These sales can be reported to the Austrian tax office in the EU One-Stop-Shop procedure.
You want to implement the VAT declaration as time-efficient as possible?
With the help of our One-Stop-Shop extension you can submit your sales recorded in Microsoft Dynamics 365 Business Central via XML declaration to the Austrian Finanz Online.
Navigation
One-Stop-Shop is integrated with the existing financial accounting system in the VAT Statements.
The search terms "nvxoss", "navax" are recognized by "Tell me what you want to do".
This allows very fast access to the individual areas of the One-Stop-Shop.

The following section explains the setup steps necessary to use the One-Stop-Shop extension.
Gen. Business Posting Groups
In order for the sales to be properly recorded in Business Central with the appropriate tax rates, you will need a Gen. Business Posting Group and a VAT Posting Group for each EU country in which you make these sales.
VAT Business Posting Groups
Requirement for the upload of the EU-OSS sales is the creation of a VAT Business Posting Group per EU country in which you make the sales.
In addition, a VAT Business Posting Group must be created for each subsidiary, which is managed under its own VAT Registration No.
For more information, see Which sales can Austrian businesses and other EU businesses declare via the EU-OSS?
Business Central automatically adds the VAT Business Posting Group when you assign the Business Posting Group to a Customer or G/L Account.
Fields, VAT Business Posting Groups
For One-Stop-Shop, the following fields have been added to the page VAT Business Posting Groups.
OSS VAT Reg. No. Subsidiary
This field only needs to be filled if there are sales made from a different VAT registration number than the VAT registration number of the company. For these a separate VAT Business Posting Group must be created for this subsidiary. The VAT registration number of the subsidiary has to be entered in the field. This allows to report sales of branches also with their own VAT registration number.
Note
If there are no such branches, leave the OSS VAT Reg. No. Subsidiary field empty.
OSS Country/Region Code
Specifies the ISO Country Code for which the EU One-Stop-Shop Statement is to be made.
Important
The 2 digits ISO EU country code must be entered here. If you select the country from the Countries/Regions table, the stored value from the EU Country/Region Code field is automatically inserted. These values must be specified to use.
General Posting Setup
When a Business Posting Group has been created, you must create the required combinations of the new business posting group and product posting groups on the Gen. Posting Setup page.
This configuration is only necessary for sales, so the purchase accounts can remain empty.
Note
If the purchase accounts are not set up for these combinations no false posting can happen in this respect.
VAT Posting Setup
This configuration concerns the VAT Posting Setup, here you also need to configure the VAT Business Posting Group with the required VAT Prod. Posting Groups to set up.
The VAT Rates of the individual EU countries can be retrieved from the following link:

Important
In addition, a separate sales tax account must be set up and an input tax account must be entered.
