What you can expect from this article

There are those moments when you think to yourself: That can’t possibly happen. It really can’t. It feels like the odds are somewhere between „being struck by lightning“ and „winning the lottery six times in a row“. And then it happens anyway: you’re standing in front of the lift in the office block, the doors open, everything as usual. A quick step forward, your car key held loosely in your hand – and suddenly it slips from your fingers. A faint metallic clink. A brief pause. And then that glance down: the key is gone. Vanished. Into the gap between the lift and the landing, exactly three centimetres wide.

From an unlikely isolated incident to a real risk

Three. Centimetres. How likely is that, really? Well, obviously: likely enough, because that’s exactly what happened here at hsp. Situations like this seem absurd at first glance. However, they happen time and time again. And usually when nobody expects them to. Which leads to more damage than one might initially think.

So losing a key leads to a whole string of consequences:

• Replacement procurement
• Loss of time
• organisational effort
• in the worst-case scenario, safety risks (e.g. with company vehicles)

In companies, people are just as keen to sweep things under the carpet

There are many parallels with the reality of business, particularly in the area of taxation. Here, too, many people think: „That won’t happen to us.“ In many companies, the subject of tax is still viewed as a purely technical task: the tax department or the tax adviser „will sort it out“. Processes have developed over time, responsibilities are implicitly defined, and documentation? Well, it exists. Surely. Somewhere.

But the reality is more complex. This is because companies operate in an environment characterised by an increasing regulatory burden, rising demands for documentation and traceability, international interdependence and advancing digitalisation. In this environment, even a minor error is enough: an incorrect tax code in the ERP system, a lack of coordination between departments, or an undocumented decision. And just like that, we have a ‘key error’ here too.

Why „unlikely“ is not a benchmark

The crucial point is not whether a risk is unlikely. What matters, instead, is simply whether it has been assessed.

Consequently, risk-aware companies systematically ask themselves two questions:

1. What is the probability of an error occurring?
2. How high is the potential amount of damage?

These two dimensions are at the heart of any effective tax compliance management system (TCMS). After all, you can only manage risks if you are aware of them.

A classic example: a company incorrectly reports its turnover over a period of several years. Not deliberately, but due to a flawed process. As a result, the error remains undetected until the next tax audit. This leads to significant consequences: back tax payments, interest, possible fines, damage to the company’s reputation and, last but not least, personal liability risks for those responsible. Suddenly, a minor oversight has turned into an existential problem.

TCMS as a strategic management tool

Companies should not set up a Tax Compliance Management System simply for the sake of having one. After all, the TCMS serves to identify, assess and manage tax risks. Ideally, therefore, it ensures that risks are identified at an early stage, errors are systematically reduced, responsibilities are clearly defined and decisions are documented in a way that can be verified. Above all, however, it creates transparency. One aspect that is often underestimated in this context is the human factor.

People tend to underestimate risks, fail to question established procedures and rely on past experience. Whilst this is helpful in everyday life, it is dangerous in a tax context. This is because tax errors rarely arise from a lack of knowledge. They arise from a lack of processes, unclear responsibilities and a lack of communication. At the same time, it is important to understand that a TCMS is not a static document. It is a living system. Organisations change, processes evolve and legal requirements are amended. An effective TCMS must reflect these dynamics and be continuously refined.

How Opti.Tax provides practical support to businesses

With this in mind, we developed Opti.Tax for Tax CMS. Our approach is practical, structured and designed to ensure that the Tax CMS is firmly embedded within the organisation in the long term. Firstly, Opti.Tax brings transparency to tax processes. Companies gain a clear understanding of where risks arise, which processes are affected and who is responsible. This transparency forms the basis for any further optimisation.

Building on this, risks are systematically assessed according to their probability of occurrence and potential extent of damage. This results in a clear prioritisation, enabling resources to be deployed in a targeted manner. In the next step, Opti.Tax assists with defining and implementing specific measures. These include process adjustments, the introduction of control mechanisms and clear documentation requirements. Practicality is key here: the measures can be integrated into existing workflows and are not perceived as an additional burden.

It all comes down to the foundations

Another key component is documentation. In the event of a tax audit, the company can at any time provide a clear account of how risks are identified, assessed and managed. This builds trust and can bring significant benefits in the event of an emergency. Finally, Opti.Tax also supports companies over the long term. The TCMS is regularly reviewed, adapted and further developed – for example, in response to new legal requirements or changes to business models. This ensures that the system remains not only up to date but also effective.
