Tax Office and Local Tax Office 
The tax office to which the business place reports the VAT and other taxes must be entered in the business place master record. Enter the number of the tax office (3 characters, unique in the whole country) as the key and the name in the tax office master data table. This table is language dependent so that you should maintain it in all possible login languages.
In the section code master data a tax office and a local tax office have to be entered since the section code is a combination for those two tax authorities and a reporting unit for the withholding tax. Even if the withholding tax reporting is done on the business place level in your company it is not sufficient to enter only the business place instead of the tax office in the section code master record. The tax reports are accessing the tax office and the local tax office field in the section code master data. Enter the number of the local tax office as the key (3 characters, unique in the whole country) and the name in the local tax office master data table. This table is language dependent so that you should maintain it in all possible login languages.
