Many managing directors are surprised when, during a grant application, bank loan assessment, or tax incentive claim, it turns out that their company’s SME classification is not what they previously believed.
However, the classification as a micro, small, or medium-sized enterprise is far more than a statistical category and has significant implications in many areas. It can affect eligibility for certain corporate tax incentives, innovation contribution obligations, the application of transfer pricing rules, and access to various grants, subsidies, or financing opportunities.
What Determines SME Classification?
One of the most common misconceptions is that an SME classification can automatically be determined by the accountant based on the available accounting data.
In reality, this often requires information that does not appear in the accounting records. Examples include ownership structure, shareholdings in other businesses, partner or linked enterprises, and, in certain cases, relationships between owners and other companies.
For this reason, the managing director plays a key role in determining SME status, as they possess the information necessary to identify which companies’ data must also be taken into account.
While the accountant can assist with applying the rules, the complete picture is usually known only to the managing director and the owners.
The Three Main Indicators of SME Classification
As a general rule, three key indicators must be examined:
- Average statistical headcount
- Annual net sales revenue
- Balance sheet total
Secondary Factors Affecting SME Classification
The SME Act also requires that, in certain cases, the data of partner enterprises and linked enterprises be considered. This can significantly alter the classification.
It is possible for a company that appears to be a small enterprise on its own to qualify as a medium-sized enterprise or even a large company when the data of related businesses are included.
When Should an SME Classification Be Reviewed?
A review of SME status is particularly important if:
- A new owner has joined the company
- The company has acquired a stake in another business
- A corporate group has been formed
- Family-owned businesses operate in parallel
- Significant organizational or ownership changes have occurred
SME Classification Can Change Over Time
Another common misconception is that SME status only needs to be determined once. Since classification is not permanent, it may change as the company’s size, ownership structure, or corporate relationships evolve.
Which Date Is Relevant for SME Classification?
Moreover, the relevant reference date is not always the same for every purpose.
For example, for innovation contribution purposes, the situation existing on the first day of the financial year may be decisive. In contrast, certain corporate tax incentives require an assessment based on the status at the end of the tax year. For investment tax incentives, the date on which the investment is reported may also be of crucial importance.
As a result, the same company may need to be assessed based on different dates depending on the specific tax benefit or obligation involved.
When Does SME Status Change? The Two-Year Rule
The so-called “two-year rule” often plays an important role in determining SME classification.
Under this rule, if a company exceeds or falls below the relevant thresholds, its classification typically does not change immediately. As a general principle, a change occurs only if the relevant conditions exist for two consecutive reporting periods.
While this rule provides stability for many businesses, it also highlights the importance of regularly and professionally reviewing SME status.
Our Advice for Avoiding Future Problems
As a managing director, it is important to address SME classification proactively. If necessary, seek assistance from your accountant or tax advisor, as an incorrect classification can have serious consequences.
A company may claim tax incentives to which it is not entitled, or miss out on grants, subsidies, or tax benefits because its classification was previously determined incorrectly.
