SAP VAT Health check
The KGT SAP VAT Health Check is a structured, expert-led assessment performed by KGT’s SAP tax specialists, designed to identify VAT risks, inconsistencies, and control gaps directly within your SAP environment.
VAT determination in SAP is driven by a complex interaction between configuration, master data, and transactional flows across multiple modules. As a result, VAT errors often remain hidden until audits, reporting, or reconciliations, when the impact is already visible.
The SAP VAT Health Check provides a fast, data-driven understanding of how VAT is actually determined in your system, and where it goes wrong.
Why VAT issues occur in SAP environments
VAT errors are rarely caused by a single issue. They typically arise from a combination of structural factors:
- Misaligned tax determination logic
- Inconsistent or incomplete master data
- Configuration gaps in tax procedures and tax codes
- Complex intercompany and cross-border transaction flows
- Lack of automated VAT monitoring and controls
Standard SAP functionality and many third party tools evaluate VAT on a transaction-by-transaction basis, without considering the full business flow. This creates blind spots — especially in multi-party and cross-border scenarios.
What the KGT SAP VAT Health Check covers
The assessment combines data analytics, configuration review, and transactional testing across SAP modules including SD, MM, and FI.
- VAT Data Analytics
Extraction and analysis of VAT-relevant transactional data to identify inconsistencies, anomalies, and high-risk transactions. - Configuration Review
Assessment of tax procedures, condition records, tax codes, and SAP tax determination logic. - Master Data Validation
Verification of VAT-relevant master data such as VAT IDs, tax classifications, and country settings. - Transactional Testing
Validation of VAT treatment across real transactions, including sales, procurement, and intercompany scenarios. - End-to-End Flow Analysis
Evaluation of VAT determination across complete transaction chains from SD billing through FI postings and VAT reporting.
What the KGT SAP VAT Health Check identifies
The assessment focuses on identifying concrete VAT risks, including:
- Incorrect VAT determination and tax code usage
- Misclassification of domestic, EU, and non-EU transactions
- Missing or incorrect VAT IDs and master data inconsistencies
- Duplicate invoices and incorrect VAT recovery
- Incorrect VAT rates, exchange rates, or tax postings
- Configuration gaps impacting VAT calculation and reporting
Findings are quantified, prioritized, and linked to their root causes.
Structured approach: from detection to remediation
The SAP VAT Health Check follows a structured methodology:
- Detection: extraction and analysis of transactional VAT data
- Risk Assessment: automated VAT recalculation and identification of inconsistencies
- Control Evaluation: review of configuration, master data, and governance
- Remediation: clear recommendations and guidance for SAP corrections
Ensuring that issues are not only identified, but structurally resolved.
What you gain
- Immediate visibility into VAT risks and inconsistencies
- Clear understanding of root causes (not just symptoms)
- Prioritization of high-risk areas and transactions
- Actionable recommendations for SAP remediation
- Stronger foundation for VAT control frameworks and UAT
From assumptions to fact-based VAT control.
When to do the KGT SAP VAT Health Check
The SAP VAT Health Check is particularly valuable:
- During or after SAP implementations (e.g. S/4HANA)
- When preparing for a new e-invoicing mandate or digital reporting obligation
- When experiencing recurring VAT issues
- Prior to VAT audits or tax authority reviews
From insight to continuous VAT control
The SAP VAT Health Check is typically performed as a one-time assessment to quickly gain insight into VAT risks and control gaps.
Many organizations subsequently implement the SAP VAT Data Analysis add-on to enable continuous monitoring, automated controls, and ongoing VAT governance within SAP.
The add-on provides:
- Real-time VAT monitoring
- Automated VAT validation
- Continuous insight into VAT determination
Moving from one-time insight to continuous control
It is a structured assessment performed by KGT’s SAP tax experts to identify VAT risks, inconsistencies, and control gaps within SAP.
You will gain clear visibility into VAT determination, cross-border and intercompany transactions, and potential compliance gaps - all presented in an easy-to-read report.
The SAP VAT Health Check includes real-time analysis, tailored automated controls, and end-to-end visibility of VAT flows across invoices, sales orders - and intercompany transactions - including review of the correctness of chain transactions (e.g. 3 or 4 parties in the chain) and EU simplified triangulation.
By automating VAT controls and flagging discrepancies, KGT's SAP VAT Health Check helps reduce risks of incorrect VAT reporting and ensures your processes meet regulatory standards.
Both internal teams and external advisors gain value - internal teams get clear insight in VAT risks, inconsistencies and control gaps within SAP, while advisors can focus directly on critical VAT issues.
It helps identify VAT that was incorrectly reported, incorrectly not deducted and flags inefficiencies, allowing organizations to reduce unnecessary costs.
Typically, the assessment can be completed within a few weeks, depending on the scope and complexity of your SAP landscape and business model(s).
No. The assessment is performed on your existing SAP environment without requiring structural system changes.
Yes. It is highly recommended to identify VAT risks before migration to avoid carrying issues into the new environment.
The SAP VAT Health Check is part of our SAP Tax services and is a structured assessment performed by KGT’s SAP tax experts to quickly provide insight into VAT risks, combining data analytics, configuration reviews, and transactional testing.
The SAP VAT Data Analysis add-on, on the other hand, is a continuous solution embedded in SAP that can be used by the organization itself on an ongoing or periodic basis, providing real-time VAT monitoring, automated controls, and continuous insight into VAT determination across processes. It is often implemented following an SAP VAT Health Check to maintain and extend VAT control.
