Automated Tax Determination For SAP

Fully compliant and automated tax processes for SAP systems

The challenge

More and more multinational businesses have European operations with complex cross-border flows and multiple foreign VAT registrations. However, SAP is often unable to handle the complex VAT rules and associated reporting requirements faced by such businesses.

Increasingly, we see tax and finance staff experiencing issues such as:

  • Significant man-hours devoted to checking and validating transactional data
  • The need to develop bespoke reports either to correct errors or format VAT-return data according to each tax authority’s requirements
  • VAT compliance risk associated with errors, omissions and disclosure discrepancies stemming from underlying SAP transactional data

How businesses may solve these issues

  • A complex sequence of manual workarounds may be developed over time . For example, businesses often develop bespoke access sequences together with a complex set of condition records in order to try and derive a complex VAT decision. 
  • The order management team manually changes the VAT characteristics of sales orders. This could be done to attempt to overcome a known limitation within SAP VAT determination and to try and force the correct the VAT result. This means a company may allow non-tax staff to make decisions - which is very high risk.
  • Staff need to manually recognise in SAP each EU triangulation transaction flow. As such ensuring staff correctly recognise when triangulation applies is a huge challenge. 
  • Likewise, where AP staff are responsible for selecting a VAT code on a purchase invoice, the business is effectively reliant on AP staff to be tax experts. It is often the case that the tax department has to spend further time reviewing and correcting the VAT coding on invoices applied by AP staff.

The consequences

Many businesses are forced to carry out significant manual work outside of their system in order to compile their VAT declarations. Typically, doing such work in Excel or in some cases within a bespoke database or reporting engine, this yet another symptom of underlying issues caused by inaccurate VAT determination in SAP.

Although practical when done on a small scale, such a manual approach is often not scalable for tax and finance teams responsible for multiple jurisdictions and VAT registrations.
