Implementation VAT reduction

Project duration: 3 months

Brief description

The German government has decided that the VAT rate will be temporarily reduced from 19% to 16% for the second half of 2020. Therefore, comprehensive adjustments in the accounting-relevant systems (master data application and incoming document system) are necessary in order to ensure invoice entry or issuing with different VAT rates.


The customer's incoming document system processes (for the most part automatically) incoming invoices from network operators for the electricity and gas divisions. Due to the VAT reduction, which can be applied either on a key date basis as of 01.07.2020 or on a time period basis for all delivery periods ending in the second half of 2020, a softening of the verification of the amount of VAT in the invoices is necessary. As an alternative, evaluation options will be created for the key user. In the master data system of the customer, the billing takes place on the customer side, which is also adapted so that the correct VAT rate is determined depending on the time of posting towards SAP. The programming takes place with .Net code, the report creation with Reporting Services and the data processing with SQL databases.

Subject description

For discounts on the input and sales side, the VAT reduction must be taken into account. Furthermore, the adjustment of the monthly rolling settlement, the year-end settlement and the postings for noted items takes place. Settlement and credit notes for the own company code and the customer-receiver company codes are provided. In addition, a script will be created to convert existing budget billing schedules to the new VAT. Other tasks in the course of this project include support for testing and partial go-live, as well as customization of documents to reflect different tax rates within a billing statement. Different scenarios for the receipt of invoices from suppliers and network operators have to be mapped. After release by the client, the adjustments recorded in the conception will be implemented in the incoming document and master data system.
