Taxes in SAP are a very important part of functionality. It is a topic of interest for different segments of the SAP community: Finance business users, Finance functional consultants, Logistics consultants and so on.
From the functional viewpoint, the taxes’ configuration is quite simple. There is a Sales Tax section within the Finance part of IMG. Most of the configuration for particular tax codes you can do in the transaction code FTXP.
However, have you ever thought about how SAP stores the data for tax configuration? If you ever had to write an overview of existing tax codes in your system, then you probably have already thought about this.
The diagram below summarizes some of the tables and their relations for tax codes’ configuration in SAP. It also shows the fields you need to extract to get a simple report: Country, tax code, GL account and description.
I must warn you that SAP Expert had to slightly simplify the diagram, excluding the tables that hold tax rates. If you need to get the rates, you need to add KONH and KONP tables into the overview.
I hope the diagram will be useful for the readers of SAP Expert. If you want to get a MS Visio version of the same file for a small fee, or have additional questions, please contact SAP Expert for details.
