Function and account assignment
The SAP Business One system automatically creates journal entries when posting-relevant documents are saved. The tax account plays a decisive role here, as it is used together with revenue or Expense accounts is posted.
The correct tax account is primarily assigned via the associated tax code, which is stored in the document lines. For manual journal entries, SAP Business One automatically calculates the sales tax based on the assigned tax code and posts the amount in a separate line. Manual journal entries can optionally use the standard sales tax code of the account.
Definition and allocation
Business users define the required tax accounts in the tax code table, which can be found under Administration in Financial Accounting. In detail, the column Tax account The corresponding input tax or sales tax account is specified in the tax code definition.
In addition, G/L account determination for sales and purchasing provides standard tax codes that the system uses for article or service transactions.
There are also special requirements for tax accounts:
• Purchase tax account: In reverse charge situations, the VAT account is defined as a purchase tax account.
• Output tax ledger account/Input tax ledger account: For tax invoices, the journal entry must be structured in such a way that an output tax invoice is credited to an output tax G/L account and an input tax invoice is debited to an input tax G/L account; the base amount must be specified.
Deviations and corrections
If an A/R credit note is based on an A/R invoice, the system automatically corrects the original tax amounts. In the case of a payment that takes a cash discount into account, the system automatically posts a correction to the VAT (in the case of an incoming payment to the bank account).
In addition, a G/L account can be permanently assigned a tax code. If this account is used for postings in the asset accounting is relevant, the account determination for the asset classes and the tax codes must be agreed with the tax consultant, as it is not recommended to change the account assignment during ongoing operations.
Relevance for master data
The country of a business partner is also relevant, as it influences the accounts that are addressed when an invoice is created (e.g. receivables a. Domestic, EU or third country). For tax reasons, the VAT number must therefore be stored in the business partner master data for customers from other EU countries or third countries. The tax code can be defined in the business partner master data depending on the tax status (mandatory, exempt, EU).
