Changes in the Taxation Procedure
Description
By means of a further indicator in the G/L account master record, you can now allow postings to be entered without tax codes for tax-relevant accounts. This is especially necessary in those countries where the tax calculation is carried out using a jurisdiction code, as otherwise you would still have to enter a dummy jurisdiction code for non-tax-relevant postings or store it in the respective master records (cost center, customer, and so on).
For all other countries, this control is not necessary since it is sufficient here to create a "Sales not controllable" tax code with zero percent, to enter it for the corresponding transactions, and not to take this indicator into consideration in tax reporting.
Change system parameters in customizing
If you post to a tax-relevant account without a tax code, a warning message
is issued. You can switch this off via the Financial accounting Implementation
Guide. To do this, choose the step 
"Change message control for taxes" . The application area of the
messages is "FS", the message number is 219.
For more information, refer to the Implementation Guide.
Dependent functions
The postings without tax codes do not generate tax information. They are therefore not taken into cnsideration by the programs for tax reporting.
