Digitalization of the Tax Compliance Management System (Tax CMS)

A level that seems unattainable?

With us, you can build an effective and future-proof Tax Compliance Management System (TCMS) that is sustainable in terms of both tax expertise and digitalisation. Thanks to our many years of experience in industry, IT and consultancy, we can provide you with practical solutions tailored to your needs, from project planning to ongoing operations, combining the best tools on the market with seamless implementation.

We can help you take your Tax Internal Control System to the next level with #nextleveltaxcompliance!

Managing tax risks with digital solutions
Tax CMS Definition
A Tax CMS - also known as a Tax Internal Control System (Tax ICS) - describes a software solution for the efficient management and organization of tax-relevant documents and information. In designing the Tax CMS, we are guided by the seven interrelated core elements of IDW PS 980, which are based on §153 AO Tax Compliance (§153 AEAO).

The benefits of upgrading to a digital tax CMS

Over the past decade, numerous companies have invested significant effort in building a Tax Compliance Management System (Tax CMS), but now face the challenge of operating the Tax CMS sustainably in regular practice.

In our view, this is primarily because most Tax CMSs rely on manual sample checks, the continuous execution and documentation of which—often in an Excel-based risk control matrix—is associated with considerable effort.

Additionally, we have found that the intended sample checks are often poorly integrated with the relevant processes. Consequently, when changes are made to the underlying processes, the sample checks quickly become ineffective. In short, many Tax CMSs exist on paper but are not implemented sustainably in practice.

Consequently, the goals of a Tax Compliance Management System — particularly indemnification, efficiency improvement and facilitating tax audits — are often not achieved. This is because these goals require an effectively implemented Tax CMS!

Our core competencies
What is Tax Compliance?

The goal of tax compliance is to minimise risk and ensure lawful tax practices. Overcome the increasingly complex challenges by benefiting from our expertise.

The WTS consulting approach

In most cases, digitalisation is the solution! But how can the Tax CMS be further digitalised and tax risk management optimised?

The answer lies partly in processes and partly in data. Rather than, or in addition to, manual risk assessments, ERP raw data should be analysed using audit rules, and risk-mitigating measures should be derived based on the results. This makes it much easier to implement automated audit routines instead of manual spot checks.

New approach to the Tax CMS using data analytics

Although it sounds simple and plausible, it is nevertheless complex in practice! In particular, there is no 'one size fits all' approach. This is because analysing ERP raw data requires an in-depth understanding of its structure and the underlying processes. Therefore, the tax department cannot avoid reflecting on where tax-relevant decisions are made within the company, at least fundamentally.

Digitalization of the Tax CMS with SAP RAM in SAP S/4HANA

Integration of SAP Signavio in SAP RAM

Using the SAP Integration Suite allows for the standard integration of SAP Risk and Assurance Management (RAM) and SAP Signavio, which can be set up in just a few steps. Integrating these two cloud applications allows risk and control information to be linked to the modelled processes in SAP Signavio, creating a comprehensive Tax CMS representation within the SAP environment. The technical interface automatically updates the information and ensures direct access between the systems. This provides an efficient, transparent solution for documenting and operationalising the Tax CMS.

SAP RAM allows comprehensive issue handling.

Anomalies (issues) arising from automated test routines can be processed in a workflow-based issue handling system. SAP Risk and Assurance Management allows you to pre-filter the results of certain test routines based on predefined rules, ensuring the efficient processing of individual issues. Additionally, tasks for investigating and correcting issues can be defined and assigned to process participants. All activities relating to the investigation and correction of issues, up to the final outcome, are documented and evaluated in SAP RAM. This lays the foundation for the standardised processing of issues from individual test routines within a project at an early stage. Utilising the automation capabilities of SAP RAM minimises the manual effort required for operationalisation, enabling the focus to be placed on the accuracy of the SAP S/4HANA data.

We will support you on this journey, working with you to develop a bespoke consulting approach. Our goal is always to establish a customised, largely digitised Tax CMS. We offer various implementation solutions in both SAP and non-SAP environments. We have extensive experience of implementing a wide range of digitalisation solutions, and our business partnering provides us with the perspective of a practitioner. We guarantee a pragmatic and practical implementation approach.
