Tax codes in SAP Business One are used to identify the tax rate and the corresponding tax accounts for specific transactions. They enable the automated calculation and posting of taxes, which plays a central role in tax management. Tax codes should be defined carefully and ideally in collaboration with a tax consultant in order to fulfil tax law requirements.

Definition and parameters of control indicators

Tax codes are displayed under Administration > Definition > Financial accounting > Tax > Tax code created. The following parameters must be taken into account:

Tax ratePercentage value of the tax for the transaction.
Tax accountG/L account for tax posting.

Tax codes are used in various documents such as incoming and outgoing invoices or journal entries. They can be selected automatically using stored rules or manually in the respective document. Standards can be stored at both business partner and item level to simplify recurring transactions.
