ITL Tax Codes with Validity Periods

Tax authorities change Tax rates frequently. Companies operating on SAP platforms therefore face the risk of running out of Tax codes available in standard SAP, as well as high costs of maintaining the Tax codes. ITL Tax Codes with Validity Periods is a solution that simplifies the management of Tax codes and Tax rate changes – In case of Tax rate changes you simply have to "end date" the old rate and add a new rate with a validity period.

Key features:
  • This product introduces the concept of Tax codes with validity periods to your SAP system. When Tax rates change, you will no longer have to create new 2-character Tax codes. All that is needed is end date the old rate and add a new rate with a new validity period.

ITL VAT Number Validation

Every company trading within the European Union is required by law to check that the VAT registration numbers (of its customers and vendors) are correct. Failure to provide evidence of such checks – for example via an extract of the VIES database, could have serious consequences to your company’s VAT position.

Key features:
  • This product introduces fully automated real-time validation of the VAT registration numbers and address data of your customers, vendors and invoices against the VIES portal of the European Commission and the BZSt portal of the German Tax authorities.
  • Full audit trail that provides evidence that the checks were performed.
